VARIANCE COMPONENTS AND SELECTION FOR FEATHER PECKING BEHAVIOR IN LAYING HENS
Provedor de dados: 21
Autores: Su, Guosheng; Kjaer, Jørgen B.; Sørensen, Poul.
Variance components and selection response for feather pecking behaviour were studied by analysing the data from a divergent selection experiment. An investigation show that a Box-Cox transformation with power =-0.2 made the data be approximately normally distributed and fit best by the given model. Variance components and selection response were estimated using Bayesian analysis with Gibbs sampling technique. The total variation was rather large for the two traits in both low feather pecking line (LP) and high feather pecking line (HP). The standard deviation was about three times as large as the mean in the observed scale, and about the same value as the mean in the transformed scale. Based on the mean of marginal posterior distribution, in the Box-Cox...

A review of Poultry Breeding stock in the Nordic Countries
Provedor de dados: 21
Autores: Sørensen, Poul; Danell, Brigitte; Brenøe, Ulrik; Tuiskula-Haavisto, Maria.
The poultry breeding is world wide concentrated in few and large breeding companies and none of them are situated in Nordic countries. Regarding egg laying stock the hybrids offered by these companies are primarily developed in order to produce in cage systems and although they are high producing stock they has some short comings when kept in free range systems in terms of inadequate behaviour, mislaying of eggs and sometimes high mortality.  The question of using cages for keeping hens has been a matter of much concern for many people and an animal welfare approaches has lead to regulations in individual countries as well as at the EEC level. In Sweden use of conventional cages was forbidden from 2002 and the EEC has  given rules which declare that it...

Quantitative trait loci detection and benefits from marker-assisted selection in dairy cattle
Provedor de dados: 21
Autores: Schulman, Nina.
The first objective of this study was to map quantitative trait loci (QTL)affecting economically important traits: milk production traits, health traits and fertility traits in the Finnish Ayshire population. The second objective was to investigate the effects of using QTL information in marker-assisted selection (MAS) on the genetic response and the linkage disequilibrium between the different parts of the genome.    In conclusion, several QTL affecting economically important traits of dairy cattle were detected. Futher studies are needed to verify these QTL, check their presence in the present breeding population, look for pleiotropy and fine map the most interesting QTL regions. The results of the simulation studies show that using MAS together with...

Djurmaterialets betydelse i ekologisk grisproduktion
Provedor de dados: 21
Autores: Wallenbeck, Anna; Lundeheim, Nils; Rydhmer, Lotta.
De djur som används i ekologisk grisproduktion i Sverige idag är selekterade för hög produktion i konventionell miljö. I den här studien vill vi ta reda på om dessa djur även är de bästa i ekologisk miljö. Det gör vi genom att undersöka om det finns genotyp-miljö-sampel för slaktgrisegenskaper mellan ekologisk och konventionell miljö. Om det finns sådana samspel så är inte de bästa grisarna i konventionell miljö de bästa grisarna i ekologisk miljö och då finns det behov av ett eget ekologisk avelsarbete (Rydhmer m fl, 2003).    Märkning och tatuering av smågrisar hos smågrisproducenten, identifiering av slaktkropparna på slakteriet och insamling av slaktkroppsdata går att genomföra i fält. Rangeringen mellan galtar efter ekologiskt fenotypiskt...

Is there something like bio-dynamic breeding?
Provedor de dados: 21
Autores: Baars, Ton; Spengler, Anet; Spranger, Joerg.
In this paper the differentiation made within the concept of naturalness will be used to explain the different approaches in breeding within the organic movement. The differentiation of the concept will result into a framework, which will be used as a tool to describe and explain the elements of bio-dynamic animal breeding. Bio-dynamics is a practical result out of the anthroposophical worldview. Bio-dynamics developed its own way to judge about relationships in the physical world, used its own language to express the holistic approach in agriculture and focused on additional relationships within the world.

Animal breeding in organic farming:Discussion paper
Provedor de dados: 21
Autores: Nauta, Wytze; Baars, Nauta; Groen, Ab; Veerkamp, Roel; Roep, Dirk.
It is uncertain whether animals which have been bred for conventional production are capable of optimum performance in organic conditions. In conventional agriculture there is a movement towards maximum control of production conditions in order to optimise animals' yield in intensive production systems. By contrast, organic agriculture is based on natural processes and closed cycles, and takes into account the underlying connections between production factors. Following organic ideology, production capacity should be curtailed by acting in accordance with guiding principles such as naturalness, animal welfare, efficient use of fossil fuels in the farm cycle, and agri-biodiversity (IFOAM, 1994). Organic production should be tied to the land, with farms...

Strategies for a diversified organic pork production
Provedor de dados: 21
Autores: Kongsted, A.G.; Claudi-Magnussen, C.; Hermansen, J.E.; Andersen, B.H.
Possible reasons for the low market share of organic pork may be heavy price competition with conventional produced pork products combined with no or small distinctive characteristics in appearance and quality, both regarding eating quality (flavour, tenderness) and ethical quality (production methods). The overall aim of this study is to identify strategies for a diversified organic pork production with high credibility and superior eating quality based on pigs foraging in the cropping system, use of a traditional breed and no castration. Preliminary results indicate that the use of a traditional breed, the Danish Black-Spotted pig, might be a way to produce pork, which in appearance differ from conventional pork and at the same time improve the...

Principles and practicality of organic dairy cattle breeding: different options and implications
Provedor de dados: 21
Autores: Nauta, MSc W.J.; Roep, Dr. D.
As yet there is no set of generally acknowledged rules for organic animal breeding. Most organic farmers depend on conventional breeding programmes, which conflict with organic principles. Do we need a separate, distinct organic breeding system? And how can we support the development of organic breeding? These questions were explored in a PhD study. In general organic farmers and other interest groups express the need for a separate, fully organic breeding system, particularly in view of the modern reproduction technologies used in conventional breeding. Also the difference in the magnitude of GxE between organic and conventional milk production indicates that a separate breeding program might be needed. In practice, however, organic farmers respond to...

Breeding in organic farming: different strategies, different demands.
Provedor de dados: 21
Autores: Nauta, Msc. W.J.; Saatkamp, Dr. H.; Baars, Dr. T.; Roep, Dr. D.
Abstract – Due to regulations organic farming is sub-jected to a different regime then conventional farm-ing. This results in different environments for ani-mals. The question is whether one overall breeding goal is sufficient to cover all different demands of organic farmers. A survey among 132 Dutch organic dairy farmers revealed that 55% of the farmers are specialized in milk production and 45% is running a multi-functional farm. The specialized milk production farms were significantly more intensive in farming compared to the multifunctional farms. Farmers from both strategies were also asked to value different breeding aspects of animals. In general farmers val-ued different aspects more or less the same: they wanted a robust, long living cow, with...

Der Beitrag der österreichischen Biobauern zur Erhaltung der   alten, seltenen Nutztierrassen
Provedor de dados: 21
Autores: Fischerleitner, Franz; Berger, Beate; Atteneder, Veronika.
The Austrian gene conservation programme for rare breeds from 2001 to 2006 re-sulted in increasing numbers of participating farms as well as increasing numbers of animals. On the whole the programme was readily accepted and successfully realized by the farmers. The percentage of participating organic farms lies with 41% signifi-cantly above the average as only 10% of all farms are organic farms. Further the number of breeding animals in the gene conservation programme proves the en-gagement of the farmers. On organic farms 11,804 animals (44%) are in use against 15,126 animals (56%) on conventional farms in 2006. However with 6.4 animals/farm the average number of animals per organic farm is a little higher than on commercial farms (5.6 animals/farm). 9%...

Autores: Hörning, Bernhard; Vössing, Ulrich; Trei, Gerriet.
Auf Grundlage von Interviews mit 16 laufenden Projekten im deutschsprachigen Raum sowie der Literatur wird ein Überblick über Alternativen für die ökologische Geflügelzucht gegeben. Bisherige Feldprüfungen von Hybridherkünften ergaben keine optimale Herkunft. Eine Zucht spezieller Ökohybriden durch die Zuchtunternehmen erscheint mittelfristig unrealistisch. Die Leistungen von Rassehühnern können gesteigert werden durch Selektion innerhalb der Rasse oder durch Kreuzungen (mit anderen Rasse- oder mit Hybridhühnern). Im Beitrag werden jeweils entsprechende Beispiele vorgestellt.

Autores: Sørensen, A.C.
I forskningsprojektet VIPiglets formulerer økologiske svineproducenter og forskere i samarbejde et nyt avlsmål for søer til økologisk produktion.    En ud af tre pattegrise i den danske økologiske svineproduktion dør før fravænning. Det skyldes blandt andet, at hver so føder flere grise, end den kan passe, og at disse grise samtidig er små og svage. Den høje pattegrisedødelighed er en barriere for at opnå en højere vækstrate i økologisk svineproduktion. Derfor er der brug for at sætte nye avlsmål for de søer, som skal bruges til udendørs, økologisk svineproduktion.

Autores: Küster, Simone; Baulain, Ulrich; Henning, Martina; Brandt, Horst.
In order to investigate if there are differences between endangered or modern pig breeds concerning growth and product quality a total of ninety fattened pigs were housed and fed after the principles of the organic farming. During the fattening period the animals got regularly weight and measured alive with magnetic resonance tomo-graphy (MRT) in order to research tissue growth. After achieving a live weight of about 120 kilogram the pigs got slaughtered. After slaughtering the carcass quality was acquired, samples were taken for investigating the meat quality and one carcass side was measured again with the MRT. Results point out that differences exist between the breeds concerning the attributes of growth, carcass and meat quality.

Genotype Environment Interaction between Organic and Conventional Dairy Production
Provedor de dados: 21
Autores: Nauta, MSc W.J.; Brascamp, Prof. E.W.; Veerkamp, Dr. R.F.; Bovenhuis, Dr. H.
Abstract – Due to genotype by environment interaction (GxE), conventional bulls might not be suitable for organic production circumstances. Therefore, lactation records from Holstein cows on organic and conventional farms were used to estimate the magnitude of GxE between organic and conventional production circumstances. GxE was quantified by estimating the genetic correlations between production traits in both environments. Genetic correlations for milk and protein yield were between 0.71 and 0.80 and found to be significantly different from unity. For fat yield the correlations were close to 0.90 and not significantly different from unity. It can be concluded that breeding values for yield traits should be adapted to organic production so that the...

Auswirkungen unterschiedlicher Duroc-Genanteile auf das ökologisch erzeugte Mastschwein
Provedor de dados: 21
Autores: Lapp, Dipl.Ing.agr. Judith; Baulain, Dr. U.; Brade, Dr. W.; Brandt, Dr. H.; Fischer, Dr. K.; Weissmann, Dr. F.
It is the aim of the present study with 93 organic fattening pigs of varying Duroc gene portion (0 %, 25 %, 50 %, and 75 %) to deduce the optimal Duroc gene percentage.  Increasing Duroc gene portions resulted in an impaired feed conversion ratio, decreasing lean meat content, and increasing intramuscular fat content. It is concluded that in a carcass quality based marketing system Duroc gene percentage should not exceed 50 %, whereas already 25 % Duroc gene portion significantly promotes meat quality. Only for marketing systems very strictly based on meat quality Duroc gene portion should have 75 % due to a significant promotion of intramuscular fat content.

Organic and conventional dairy farmers prefer different improvements in breeding goal traits
Provedor de dados: 21
Autores: Slagboom, Margot; Kargo, Morten; Edwards, David; Sørensen, Anders Christian; Thomasen, Jørn Rind; Hjortø, Line.
In dairy cattle breeding, breeding goals (BG) are developed and subsequently a selection index that farmers want to use. Therefore it is important to take their preferences for BG traits into account. Two production systems that are expected to influence farmer preferences for BG traits are organic and conventional systems. The aim of this study was to characterize preferences of organic and conventional Danish dairy farmers for improvements in BG traits for Holstein cattle. A survey was established to characterize preferences for improvements in ten traits, by means of pairwise rankings using the online software 1000Minds. These pairwise rankings were based on equal economic worth of trait improvements. The survey was filled in by 106 organic and 290...

Bayesian analysis of the linear reaction norm model with unknown covariate
Provedor de dados: 21
Autores: Su, G.; Madsen, P.; Lund, M.S.; Sørensen, D.; Korsgaard, I.R.; Jensen, J.
The reaction norm model is becoming a popular approach for the analysis of G x E interactions. In a classical reaction norm model, the expression of a genotype in different environments is described as a linear function (a reaction norm) of an environmental gradient or value. A common environmental value is defined as the mean performance of all genotypes in the environment, which is typically unknown. One approximation is to estimate the mean phenotypic performance in each environment, and then treat these estimates as known covariates in the model. However, a more satisfactory alternative is to infer environmental values simultaneously with the other parameters of the model. This study describes a method and its Bayesian MCMC implementation that makes...

Livestock breeds and Organic farming systems
Provedor de dados: 21
Autores: Van Diepen, Pauline; McLean, Dr Barbara; Frost, David.
Organic livestock farming has grown in Wales in recent years. It is focused on producing animals from a predominantly forage-based system, with an emphasis on maintaining animal health through improved welfare and a reduction in the use of routine, conventional veterinary treatments. Breeding and feeding are important factors of the health and welfare of farm animals in organic systems. The guidelines of EU regulation (EC) 1804/1999 address the issue of sourcing of (breeding) stock. Moreover, only activities such as the use of genetically modified organisms (GMOs) and embryo transfer are excluded, and few provisions are included that concern breeding. A number of breeds used in conventional farming could be considered as ’high maintenance’ animals...

The accuracy of genomic predictions based on reference populations consisting of bulls only and bulls and cows was compared. The gain in accuracy was very small or not existing at all. Reasons could be that the number of cows was too small for a reference population consisting of 4,085 bulls and that the cows and bulls were too closely related. Nevertheless, genotyping cows and subsequent inclusion in the reference population should be accelerated.

Selective Breeding in Organic Dairy Production
Provedor de dados: 21
Autores: Nauta, Wytze.
Organic dairy farming started to take off in the early 1990s, when the European Union laid down organic standards for animal production. Until now, however, only incidental steps have been taken towards organic breeding and organic farmers mainly use breeding stock from conventional breeding programmes. This thesis focuses on the possibilities for breeding in organic dairy farming.  This thesis starts with describing the basic backgrounds of organic dairy farming and the results of a study that was carried out in 1999-2000 on the vision on cattle breeding. The main conclusions are that breeding in organic dairy farming should be in line with the intensions of organic farming and that farmers need animals that fit to their extensive farming system.

Genetic Improvement of Livestock for Organic Farming Systems
Provedor de dados: 21
Autores: Boelling, Dorothe; Groen, Ab F.; Sørensen, Poul; Madsen, Per; Jensen, Just.
Over the last two decades, more and more farmers converted from  conventional to organic farming systems. The few breeds and genetic lines which are intensively used in conventional production systems are not necessarily well adapted to the conditions in organic farming, because  genotype * environment interactions may cause individual genotypes performing well in one environment to do poorly in another surrounding.   An example in poultry is given, illustrating that laying hens which were selected for high egg production in a cage, had a considerable decrease in number of eggs laid in a free-range system and furthermore developed unfavourable behaviour patterns like feather pecking. The range of phenotypes produced by one genotype can be determined by...

In vielen Ländern ist in den letzten Jahrzehnten ein deutlicher Anstieg der Milchleistung bei Kühen in der Milchviehhaltung zu beobachten. Gleichzeitig ging bei steigendem Kraftfuttereinsatz der Weidegrasanteil in den Milchviehrationen zurück und wurden die Kühe auch größer und schwerer. Fasst man die Literaturergebnisse zur Eignung von Hochleistungstieren für die (konsequente) Weidehaltung zusammen, dann zeigt sich folgendes Bild:  • Die tägliche Weidefutteraufnahme ist im Gegensatz zur Stallhaltung mit 15–20 kg T pro Tier stärker begrenzt. Als Ursachen dafür werden die begrenzte Fresszeit, Bissfrequenz und Bissanzahl diskutiert.   • Hochleistungstiere mobilisieren zu Laktationsbeginn im Vergleich zu niedrig leistenden Kühen über einen längeren Zeitraum...

Imputation of genotypes can be used to reduce the implementation costs of genomic selection. In this study, we evaluated the accuracy of genotype imputation from Illumina 54k to Illumina High Density (HD) in Brown Swiss cattle. Genotype data comprised 6,106 54k and 880 HD genotyped bulls and cows of Brown Swiss and Original Braunvieh cattle. Genotype data was checked for parentage conflicts and SNP were excluded if MAF was below 0.5% and SNP call rate was lower than 90%. The final data set included 39,004 SNP for the 54k and 627,306 SNP for the HD chip. HD genotypes of animals born between 2004 and 2008 (n=365) were masked to mimic animals genotyped with the 54k chip. Methods used for imputation were FImpute and Findhap V2.

The goal of the project „Implementation of a consulting network for ecological dairy breeding based on the ecological total merit index” is the genetic improvement of dairy herds of ecologically working farms in Bavaria. The centerpiece of the project is the development of an ecological module within the internet-based commercial mating program of the LKV Bayern.  The ecological mating program automatically analyses the breeding values for all cows and offers adequate sires for mating with respect to the genetic strengths and weaknesses of the cow compared with all cows on ecological farms. By working with the program the farmers get information on the genetic background of the herd and will become sensitized for problems of selection. The program can be...

The role of molecular markers and marker assisted selection in breeding for organic agriculture
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.; Backes, Gunter; de Vriend, H.C.; Østergård, H.
Plant geneticists consider molecular marker assisted selection a useful additional tool in plant breeding programs to make selection more efficient. Standards for organic agriculture do not exclude the use of molecular markers as such, however for the organic sector the appropriateness of molecular markers is not self-evident and is often debated. Organic and low-input farming conditions require breeding for robust and flexible varieties, which may be hampered by too much focus on the molecular level. Pros and contras for application of molecular markers in breeding for organic agriculture was the topic of a recent European plant breeding workshop. The participants evaluated strengths, weaknesses, opportunities, and threats of the use of molecular markers...

Autores: Slagboom, Margot; Kargo, Morten; Edwards, David; Sørensen, Anders Christian; Thomasen, Jørn Rind; Hjortø, Line.
The aim of this study was to characterize preferences of farmers with Red Danish Cattle (RDC) or Jersey herds. A breed-specific survey was established to characterize preferences of farmers for improvements in ten traits, by means of pairwise rankings using the online software 1000Minds. These pairwise rankings were based on equal economic worth of trait improvements. The RDC-survey was filled in by 87 farmers and the Jersey-survey by 76 farmers. Both RDC and Jersey herds had the highest preference for improvements in mastitis, followed by milk production. The lowest preference was given to calving difficulty. By means of a cluster analysis distinct clusters of farmers were identified and named according to the trait improvements that were the most...

A selection experiment was initiated in 1996 in which selection for (HP line) and against (LP line) feather pecking was performed. The foundation stock was a White Leghorn layer strain established in 1970 and maintained since then as a random bred control line at the Institute. Six hatches were produced over three generations. At the age of 68 wk (gen. 0, 1996), 35 wk (gen. 1, 1997), 30 wk (gen. 2, 1998), and 27 wk (gen. 3, 1999) female birds were transferred to observation pens and their feather pecking behaviour was recorded. In each generation, 30 females and 8 males were selected from approx. 200 females and 60 males. Selection criteria was breeding value estimated by animal model on the trait  ‘number of bouts of feather pecking per bird per hour’....

Seven different pig breeds were kept under conventional and under organic feeding and housing conditions on two performance testing stations to analyse genotype-environment interactions for meat quality traits. Genetically controlled physical pork quality traits like pH- and EC-values are unaffected by both housing and feeding systems and no genotype-environment interaction could be found. In contrast, chemical meat characteristics like intramuscular fat content and fatty acid pattern are strongly influenced by genotype and feeding and a significant genotype-environment interaction. But no considerable reranking could be observed. The differences are caused by the differences in energy and amino acid supply between environments and variable lean meat...

Within organic livestock farming, the use of AI versus natural mating is under steady discussion. However, no special organic breeding programs without AI are set in place so far. The present study takes goat breeding in Germany as an example to show how an organic breeding program without biotechnology could be organised. As basis, breeding planning on different breeding plans is carried out: the breeding program in place, a breeding program with buck rotation within “buck circles” and a breeding program with AI are evaluated. It can be shown that within smaller populations (here: goat breeding in South Germany) a buck rotation scheme with progeny testing is superior in genetic gain than the actual and a breeding program based on AI. In a second step, in...

Modellrechnungen zum Einfluss der Lebendmasse von Milchkühen  auf Futtereffizienz und Kraftfutterbedarf

On the basis of calculations the effects of dairy cow life weight on feed efficiency and  concentrate demand for a whole lactation have been investigated. The results show,  that the annual milk yield is not a sufficient efficiency indicator because efficiency is  strongly affected by the life weight. To compensate for an increase in life weight of 100  kg the annual milk yield of dairy cows must increase per 12-13 % to achieve the same  feed conversion efficiency (kg ECM/kg DM, kg ECM/MJ NEL). Given this, heavier  cows need a higher proportion of concentrate in the annual ration because feed intake  increases to a lower extent than the energy requirements. We conclude that in the  cattle breeding efficiency parameters have to be considered and that for...

Possibilities and requirements for organic dairy breeding lines    Until now, improvements in the efficiency of organic dairy production have mainly occurred through better management, feeding and production strategies, using the dairy cattle breeds developed in conventional production systems. The potential of breeding lines of dairy cattle that are genetically adapted to organic milk production is essentially unexploited even though specific lines offer the potential to breed for cows with specific characteristics.   The main reason why organic lines of dairy cattle not have been established in the past is most likely based on the assumption that the correlation between the breeding goals in the two production systems is above 0.8.

At the local level the values of the cattle were more related to everyday livelihood strategies of single households and families, whereas the representatives of the republic, in line with the newspapers, highlighted the importance of the cattle for Sakha's food production and for national identity. Thus, individuals at different levels were in favour of conserving the cattle, but for different reasons. The local residents and experts were more concerned about developing economically sustainable cattle production, whereas the experts in Yakutsk were concerned about the conservation of genetic resources. The genetic studies have indicated that Yakutian Cattle show genetic distinctiveness and have genetic value for the maintenance of cattle diversity.

Quantifying the value of genetically specific organic lines within dairy breeding
Provedor de dados: 21
Autores: Slagboom, Margot.
In animal breeding, breeding goals are defined to give relative importance to certain traits, usually based on economic weights (Groen et al., 1997). In Denmark, Finland, and Sweden, the Nordic Total Merit index (NTM), based on common economic weights, is used as the breeding selection tool in dairy production (Kargo et al., 2014). Breeding goals are defined for specific production systems and circumstances. To develop a breeding goal that farmers want to use, it is important to take the objectives of farmers into account. Setting up a breeding goal that does not correspond to the preferences of farmers will make little sense (Nielsen et al., 2014). These preferences can be defined by using farmer choice experiments, for example using conjoint analysis...

Possibilities for Breeding in Organic Dairy Farming
Provedor de dados: 21
Autores: Nauta, Wytze.
In the organic sector there is an ongoing debate about the development of organic breeding methods. The debate revolves around two issues: 1) how the principle of naturalness in organic agriculture (that is, using natural processes wherever possible) can be reconciled with the increasing use of modern reproduction techniques in conventional breeding; and 2) whether animals produced by conventional breeding programs are actually suitable for organic agriculture or whether the organic sector itself should start producing animals that fit into organic production systems. Investigations into these issues gave rise to a doctorate research: “Selective breeding in organic dairy production”

Herd characteristics influence farmers’ preferences for trait improvements in Danish Red and Danish Jersey cows
Provedor de dados: 21
Autores: Slagboom, Margot; Kargo, Morten; Edwards, David; Sørensen, Anders Christian; Thomasen, Jørn Rind; Hjortø, Line.
ABSTRACT  The aim of this study was to characterize preferences of farmers for breeding goal traits with Danish Red (DR) or Danish Jersey (DJ) cows. A breed-specific survey was established to characterize farmers’ preferences for improvements in 10 traits, by means of pairwise rankings using the online software 1000Minds. These pairwise rankings were based on equal economic worth of trait improvements. The DR survey was filled in by 87 farmers and the DJ survey by 76 farmers. Both DR and DJ farmers gave the highest preference to improvements in mastitis, and the lowest to calving difficulty. By means of a cluster analysis, three distinct clusters of farmers were identified per breed. Comparisons of herd characteristics between clusters suggest that farmers...

Ethical Concerns in LowInputBreeds. Background Paper for the LIB Symposium in Wageningen 15-16 March
Provedor de dados: 21
Autores: Jensen, Karsten Klint.
This paper is first part of a review of ethical concerns in the LowInputBreeds project. In this part, the overall context for raising ethical concerns for breeding for low input animal production and assessing these concerns is characterized. Low input animal production is different from conventional production in several important ways. This means that it faces a partly different array of ethical challenges, but also that the background for ethical assessment in many ways is different.

Genetic Improvement of Livestock for Organic Farming Systems
Provedor de dados: 21
Autores: Boelling, D.; Groen, A.F.; Sørensen, P.; Madsen, P.; Jensen, J.
Organic farming which experienced a constant rise over the last two decades is a system based on sustainability and on a concept tending towards functional integrity. Legislation as well as the wish to produce separately from conventional farming raise the question whether organic farming should be conducted completely apart from conventional farming or not. This paper discusses the aspects that affect animal breeding under these circumstances, e.g., maintaining genetic diversity by using local breeds and possible G×E interactions which might occur when breeds adapted to conventional farming systems are used in organic farming. Ways of modelling G×E are presented, moreover examples of G×E in dairy cattle, swine, and poultry are given. Trends in selection...

Genetic improvement on feather pecking behaviour by selection is promissing
Provedor de dados: 21
Autores: Su, Dr. Guosheng; Kjaer, Dr. Jørgen B.; Sørensen, Prof. Poul.
Long term selection of laying hens for production in cage systems could have resulted in a poor adaptation to other rearing systems. One of the problems with the poor adaptation is feather pecking. The objective of the present study was to investigate genetic variation in feather pecking behaviour and genetic improvement on this trait by selection using an appropriate data-transformation and an animal model. Conclusions Large phenotypic variation for feather pecking behaviour.     No full-sib group effect can be found, indicating that maternal effect is negligible. Moderate or low heritability.   Genetic improvement on feather pecking by selection is effective.

Genetics of sow efficiency in the Finnish landrace and large white populations
Provedor de dados: 21
Autores: Serenius, Timo.
The results showed that the sow efficiency traits are generally lowly heritable. The only exceptions are buck kneed on fore legs (conformation trait), age at first farrowing and gestation length, which are moderately heritable.   The most substantial unfavorable correlation among sow efficiency traits exists between litter size and piglet mortality.   In general, there was a tendency for sow efficiency traits to be favorably correlated with performance traits, and unfavorably with carcass lean and fat percentages, whereas there was no clear association between sow efficiency and meat quality.

The objective of this study was to evaluate the variability of the αs1-casein locus in the Scopelos breed. Skopelos is an indigenous Greek dairy goat breed that is characterised by high milk yield and robusteness. The notion is that the extensive polymorphisms of the caprine gene (CSN1S1) that encodes the aS1 casein (CN) fraction in different goat breeds is associated with milk yield and composition. The latter are investigated and discussed for Skopelos goats.

Autores: Suárez,Olga V.; Kravetz,Fernando O.
Dyad encounters between male and female adults of Akodon azarae (Fischer, 1829) were analyzed by means of observational techniques in a natural closure during the breeding and non-breeding seasons. The animals were held in observation during 21 days, with daily 15-minute recordings of interindividual separation distance, relative displacements, characteristics of the male-female interaction, copulation, and construction and exclusive or shared use of nests by each pair. The couples, which bred successfully, showed, on average, the longest separation distance between male and female allowed by the closure. During the first two weeks of gestation the females exhibited more displacements than their respective mates did. The male-pregnant female encounters...

Wheat trials - How reliably do wheat varieties perform under different organic farming conditions?
Provedor de dados: 21
Autores: Döring, Thomas F.; Haigh, Zoe; Pearce, Helen; Pearce, Bruce; Jones, Hannah; Clarke, Sarah; Wolfe, Martin.
A major obstacle in the development of organic farming in the UK is the central problem of winter wheat production. At present, there is a substantial gap between the supply of home-grown organic milling wheat and demand, partially due to shortfalls in both wheat yield and quality. Progress is being made in organic wheat breeding programmes across Europe, although the varieties arising from these are not widely available in the UK. A crucial and unanswered question is how reliably varieties will perform under the diverse conditions that prevail on organic farms. Wheat trial results reported here indicate that the main effects of variety, location, year, or farming practice may often be more important than the complex interactions among these factors....

Création de nouveaux cépages et testage des meilleures obtentions en vue de leur homologation. Etude de l'intérêt de nouvelles obtentions interspécifiques d'autres instituts
Provedor de dados: 21
1. L'aire d'adaptation des cépages cultivés est souvent très restreinte. Certaines régions viticoles ne disposent que d'une palette variétale très limitée. L'hybridation peut permettre de combler ce manque en combinant les aptitudes des parents retenus. Les principales lacunes subsistent actuellement au niveau de cépages rouges de haute qualité pour des vignobles peu adaptés aux traditionnels Pinot noir et Gamay en raison de conditions pédoclimatiques particulières. Au niveau des blancs, une attente subsiste pour un cépage réellement adapté aux conditions tessinoises ainsi que des possibilités de diversification pour d'autres régions viticoles au climat humide et frais. La sélection de cépages rouges destinés à apporter couleur, tannins et structure en...

New models for plant breeding: Key elements for collaboration within the food chain
Provedor de dados: 21
Autores: Nuijten, E.H.A.C.P.; Janmaat, Leen; Lammerts van Bueren, E.T.
As the financial threshold for cost-effective breeding continues to be raised, increasingly more crops are becoming 'too small' for breeding. The long-term consequence is that production of these crops will become increasingly difficult, because the availablevarieties will not be adapted to future changes in the cultivation system (new methods,new diseases, etc). The question is how to develop alternative crop breeding models for small markets.This is not only a problem for the organic sector, but increasingly also for minor crops within the conventional sector. To address this problem, the Louis Bolk Institute (LBI) is developing innovative approaches to funding and organizing crop breeding for small markets. For various arable crops the LBI has initiated...

'Suvetar' and 'Valotar' - new strawberry cultivars
Provedor de dados: 21
Autores: Hietaranta, Tarja; Parikka, Päivi.
The strawberry (Fragaria × ananassa) cultivars ‘Suvetar’ and ‘Valotar’ have been released from the breeding programme of MTT Agrifood Research Finland. Both new cultivars overwintered as well as the control cultivars ‘Jonsok’ and ‘Polka’. ‘Suvetar’ overwintered even better than ‘Polka’. ‘Suvetar’ was produced from the cross ‘Polka’ × ‘Emily’. It scored better than the control cultivars for sensory assessed skin resistance. Measured fruit firmness of ‘Suvetar’ was not significantly different from that of ‘Polka’, but was better than ‘Jonsok’. ‘Valotar’ originates from a cross between ‘Jewel’ and ‘Senga Sengana’. Its measured fruit firmness was better than that of ‘Jonsok’ and ‘Polka’. Considering sensory assessments, the good firmness seems to be largely...

A field trial with carrots was carried out in 1998 at two sites in Hesse (North: loamy soil in Neu-Eichenberg; East: sandy soil in Queck) to compare 6 open pollinating and 6 F1 hybrids under an Organic Farming regime. Characteristics of cultivation, harvest, quality, and longevity were measured. Of the parameters of cultivation and harvest the hybrids showed a more intensive foliage growth, higher marketable yields (plus 29 and 25%), and more homogeneous taproots than the open pollinating cultivars. Picture forming methods clearly separated the samples into the two groups of breeding methods. The open pollinating cultivars were characterized by higher degrees of form intensity and ripeness and a stable vitality. The hybrids of the sandy site had a better...

Provedor de dados: 21
Autores: Wanke, Diethild; Biedermann, G.
Not only the biodiversity of wild species, but also the diversity in livestock is declining rapidly: Out of 6.300 registered livestock breeds in the world 1.250 are endangered or already extinct. In Germany 16 out of 32 cattle breeds are endangered, while three of the most popular cattle breeds make up 92 % of the more than two million herd-book cows. Due to their adaptation to local conditions on first sight many rare and endangered cattle breeds appear to be well suited for organic farming systems, but the percentage of rare breeds on organic farms is not much higher than on conventional ones. Council Regulation (EC) No 1804/1999 on livestock production in organic farming recommends to encourage biological diversity and to favour the use of breeds which...

Seed-the source of life. And woman holds the seed with the hope of new life.    Instead of producing diverse seed from homestead agriculture, women are engaged traditionally to select seed, drying, preserving, protecting during storage, saving them from any economical crisis of the family. To ensure the seed quality and the perfect storage place &amp; methods, women hold the vast knowledge. They decide the quantity and variety of seed to be saved and the method of preservation. Seed selection by women is a continuous activity. Working in the fields, they observe the plants and decide which seeds to select. They identify plants of good quality on the basis of size, grain formation and their resistance to pests and insects. Here a woman looks at the seed...

There are numerous instances in which induced plant resistance responses (IR) have  been demonstrated. However, before IR can be made use of in practice it is important  to understand as much as possible the ecology and genetics of the inducing agents  and their interactions with plants and pathogens. Effects of host genetic background  were tested with thirteen tomato varieties and two isolates of Phytophthora infestans.  Isolate effects on inducibility were tested with six varieties and six pathogen isolates.  Leaf disks of plants that had been treated with BABA (DL-3-aminobutyric acid) or  water were inoculated seven days later with 20 µl sporangial solutions of 5*104  sporangia ml-1. All experiments were repeated three times with six replications each....

Participatory cotton breeding for organic and low input farming in India
Provedor de dados: 21
Autores: Messmer, Monika; Roner, Tina; Finckh, Maria R.; Forster, Dionys; Rajeev, Verma; Rajeev,  Baruah; Shreekant S, Patil.
Organic cotton production currently takes place in 22 countries resulting in 241’697 metric tons of fibre and 1.1% of the global cotton production (Truscott et al. 2010). Up to 80% of world’s organic cotton is produced in India. However, this market is threatened due to the displacement of traditional cotton species and cultivars by genetically modified (GM) hybrids selected for high input farming. Organic cotton farmers are facing increased difficulties in finding suitable cultivars in India (Nemes, 2010). Moreover, there is a big risk of physical and genetic contamination of organic cotton with GM cotton and the loss of locally adapted genetic resources. Therefore fast action is needed to re-establish a GM-free seed chain and breeding programs for...

Hybrid varieties are increasingly and widely used in organic farming, although there has  never been a conscious decision to do so. This is especially true for vegetables and maize. For bread cereals, especially rye, the decision can still be taken in Switzerland. Organic rye is grown on only 250 ha, about 20% of which are hybrid varieties. About 60% of the total organic demand is imported.

Diversity of mitochondrial large subunit rDNA haplotypes of Glomus intraradices in two agricultural field experiments and two semi-natural grasslands
Provedor de dados: 21
Autores: Börstler , Boris; Thiéry, Odile; Sýkorová, Zuzana; Berner, Alfred; Redecker, Dirk.
Glomus intraradices, an arbuscular mycorrhizal fungus (AMF), is frequently found in a surprisingly wide range of ecosystems all over the world. It is used as model organism for AMF and its genome is being sequenced. Despite the ecological importance of AMF, little has been known about their population structure, because no adequate molecular markers have been available. In the present study we analyse for the first time the intraspecific genetic structure of an AMF directly from colonized roots in the field. A recently developed PCR-RFLP approach for the mitochondrial rRNA large subunit gene (mtLSU) of these obligate symbionts was used and complemented by sequencing and primers specific for a particularly frequent mtLSU haplotype. We analysed root samples...

Autores: Bapst, Beat.
In Switzerland cattle are kept in a range of different production systems and environments: From lowland to mountain area, from intensive to extensive feeding systems and from conventional to organic production systems. Some of these environments can be classified as harsh environments. It is assumed that some genotypes affect traits differently in diverging environments. If that would be the case, genotype x environment (GxE) interactions would cause re-rankings of the cattle’s corresponding breeding values in the breeding value list.

There is an ongoing discussion amongst researchers and farmers involved in organic horticulture concerning the role that F1 hybrid varieties should play in organic farming. Proponents of hybrids state that their use is already much established in organic farming and that it would be a step backwards to dispense with them. Agronomic superiority of hybrids over open pollinated (OP) varieties is often claimed. Opponents to hybrid varieties claim that heterosis puts an emphasis on biomass accumulation and yield but that the more subtle aspects of ripening and creation of aroma are neglected in hybrid varieties.

Organic Agriculture is especially affected by the increasing spread of stem rust in rye (Puccinia graminis f. sp. secalis) because there is a lack of resistant cultivars in Germany. To analyze the virulence situation of rye stem rust, 71 single-pustule-isolates were established and 30 of those were tested with a differential set consisting of 19 lines. The isolates could be classified into 22 different pathotypes. Only seven pathotypes could be found more than once. Most of the isolates showed a complexity of five virulences. In a preliminary analysis a Simpson index of 0,98 was found indicating a high level of diversity of German stem rust populations. Nine of 19 tested lines reacted fully resistant in seedling stage. In 2011, 70 and 30 rye populations,...

While grain legumes can be regarded as highly valuable protein source for animal nutrition, certain drawbacks inhibit their use as sole foodstuff for livestock. The nutrient quality is reduced by low concentrations of tryptophan and sulfur amino acids. In the past substantial breeding effort has been invested in the reduction of antinutritional components and disease resistance while the protein quality has not been a focal point. To improve the protein quality the elevation of the low sulfur amino acid content is of prominent importance especially for organic production where high methionine feed components are rare. The present work tries to establish a method to select methionine enriched grain legumes for further breeding steps. Agronomical important...

Effektiv användning av DNA-markörer för förbättrad utveckling av friska plantor
Provedor de dados: 21
DNA-markörer är det bästa verktyget för dokumentation av genetisk variation och i strävan att säkra genetisk mångfald i jordbruket. Via inkorsning av landraser och vildtyper av korn och vete utnyttjas naturligt förekommande unika resistens- och allelopatikällor och dessutom tillförs genetisk variation till odlinsmiljön. Med DNA-markörer kan önskade, naturligt förekommande gener mycket effektivare och snabbare kombineras i miljövänliga sorter med långvarig och hållbar resistens som följd. Odling av korn och vete på 2000-talet kräver mindre fungicider och herbicider och har en utökad genetisk variation.    Det som i dag begränsar användningen av DNA-markörer är tillgången till kopplade markörer för viktiga egenskaper. Projektet har som mål att med...

Screening for Barley Waterlogging Tolerance in Nordic Barley Cultivars (Hordeum vulgare L.) Using Chlorophyll Fluorescence on Hydroponically-Grown Plants
Provedor de dados: 21
Autores: Bertholdsson, Nils-Ove.
Waterlogging can reduce crop yield by 20-50% or more, and lack of efficient selection methods is an obstacle in plant breeding. The methods currently used are mainly indices based on germination ability in Petri dishes and leaf chlorosis in plants grown in waterlogged soils. Cultivation in oxygen-depleted nutrient solution is the ultimate waterlogging system. Therefore methods based on root growth inhibition and on fluorescence in plant material hydroponically grown in oxygen-depleted solution were evaluated against data on biomass growthbiomass accumulation in waterlogged soils. Both traits were correlated with waterlogging tolerance in soil, but since it was easier to measure fluorescence, this method was further evaluated. A selection of F2 plants with...

Ethical Problems and Breeding Goals: Pigs
Provedor de dados: 21
Autores: Edwards, Sandra.
Ethical problems in pig production systems arise when the rights of different stakeholders conflict.  These rights can be summarised in the ethical principles of wellbeing, autonomy and justice. The stakeholders who should be considered are the animal itself, the farmer, the consumer (and wider society) and, more generally, the natural environment.

Interaktionen zwischen Genotyp und Ort sind ein Vorteil von  lokaler Züchtung von Ackerbohnen (Vicia faba L.)
Provedor de dados: 21
Autores: Ghaouti, L.; Link, W.; Vogt-Kaute, W.
Organic farming is based on low productivity environments regarding the restricted supply of inputs. Thus, to maximize the response of selection, the local breeding approach was put forward for organic agriculture. To analyse this approach, efforts of organic farmers and scientists were combined in a pertinent, participatory breeding approach using spring faba bean as crop. A set of genotypes with different levels of heterozygosity and heterogeneity were tested in four organic farms and one conventional location. Results for grain yield showed that the genotype-location interaction was highly significant and contributed to a large extent to the yield variation. The findings indicated that indeed local breeding programs could give greater genetic gains for...

Greenhouse screening for Fusarium wilt resistance in lupine
Provedor de dados: 21
Autores: Kuptsov, N.; Christiansen, J.L.; Raza, S.; Joernsgaard, B.
Fusarium wilt can cause total crop failure. Evaluation of Ffusarium resistance in heavily infected soil were performed in a grenhouse where the dominant fusarium species in the soil in descending order was F. oxysporum then F. avenaceum, F. culmorum, F. solani, F. gibbosum. Large fusarium wilt presure was observed and fully susceptible lines were completely destroyed by Fusarium wilt caused by F. oxisporum. Segregation in F2 and F3 in L. angustifolius showed that resistant genotypes have two dominant non-allelic resistance genes to wilt. We call this gene Relation to fusarium oxisporum (Rfo1,Rfo2). Susceptible genotypes have either two wild genes (++ ++) or one wild and one dominant resistant gene (++ Rfo2 Rfo2, or Rfo1Rfo1 ++). Crossing ‘++ Rfo2Rfo2’ to...

Food Soybean Varieties in Low-Input Conditions  Grain Yield and Quality from Three NE Italy Environments
Provedor de dados: 21
Autores: Miceli, F; Centa, M; De Infanti, R; Signor, M.
Soybean has been diffusely grown in northern Italy since early 1980s. Indeed, at present the organic area (less than 3 % of the total) and the  practical absence of certified non-GM productions are key issues for farmers and food processors. In 2013, four food-grade varieties were tested under  organic or low-input conditions in three environments of Friuli, NE Italy. Environments had a large impact on grain yields, genotypes on grain  composition. Late planting resulted in lower yields and high-protein seeds. Seed protein levels were associated to visual seed quality.

Screening for resistance to Fusarium head blight in spring wheat cultivars
Provedor de dados: 21
Autores: Scholten, Dr. Olga E.; Steenhuis-Broers, Greet; Osman, Aart; Bremer, Esther.
Fusarium fungi cause Fusarium head blight in wheat. This disease is a problem that occurs both in organic and conventional farming systems. As Fusarium fungi produce mycotoxins in wheat kernels they are a threat to human and animal health. Breeding for disease resistance is the only way to prevent or reduce the occurrence of the disease. The aim of the current research project is to identify different  mechanisms of resistance in cultivars and breeding lines to be used in further breeding programmes.

Ökologisches Rebpflanzgut – Wege zur Erzeugung und Verbreitung
Provedor de dados: 21
Autores: Gehr, Eva; Zerger, Uli; Eder, Joachim.
Im ökologischen Weinbau war es jahrelang üblich, konventionelles Rebpflanzgut zu verwenden. Der Grund für die Nichtverfügbarkeit von Ökoreben war die Einschätzung, dass die ökologische Rebpflanzguterzeugung sehr risikoreich ist und notwendige Voraussetzungen nicht erfüllt sind. Die zentrale Frage des auf Feldforschung basierenden Vorhabens lautete daher: Welche Voraussetzungen müssen erfüllt sein, damit ökologisches Rebpflanzgut erfolgreich hergestellt werden kann und die gleiche Qualität aufweist wie der konventionelle Standard?  In Feld- und Laborversuchen wurde schwerpunktmäßig nach geeigneten Behandlungsmitteln zur Desinfektion von Veredlungsmaterial gesucht und der biologische Pflanzenschutz in der Rebschule erprobt.

Nachhaltige Verbesserung der Verfügbarkeit ökologisch vermehrten Gemüsesaatguts für den Erwerbsanbau durch on-farm Erhaltung, Züchtung und Vermehrung
Provedor de dados: 21
Autores: Fleck, M.; Nagel, C.; Henatsch, C.; Bauer, D.
Die Verfügbarkeit von ökologisch vermehrtem Saatgut bzw. die Sortenauswahl wird insbesondere bei Gemüse als unzureichend eingestuft. Die verwendeten Sorten sind bei vielen Gemüsekulturen zum überwiegenden Teil Hybriden, die für eine /On-farm/-Erhaltung ungeeignet sind oder im Falle von aus Zellfusion (Protoplasten- oder Cytoplastenfusion) stammenden CMS-Hybriden nicht mehr fertil und auf Betrieben der Ökolandbauverbände per Richtlinie verboten sind.  Diese beiden Aspekte der Saatgutfrage waren maßgebend für den Start dieses Projektes.  Mit dem Ziel, die Eignung der Sorten für den ökologischen Gemüsebau zu prüfen, wurden 164 Saatgutmuster noch verfügbarer Populationssorten der Kulturen Kohlrabi (15), Möhren (86) und Porree (63) am europäischen Saatgutmarkt...

Samenfeste Möhrensorten im Vergleichsanbau mit Hybridsorten
Provedor de dados: 21
Autores: Arncken, Christine.
Hybridzüchtung ist seit Mitte des letzten Jahrhunderts weltweit auf dem Vormarsch. Im Bio-Landbau hat sie jedoch Gegner, die neben politischen,  ethischen und ökologischen Bedenken fürchten, dass durch sie die innere Qualität von Kulturpflanzen leidet (Arncken 2005).  Manche Bio-Züchter wie die SATIVA (CH) und der Verein Kultursaat e.V. (DE) setzen ganz auf offenbestäubende (OP-) Sorten, wofür die Züchtung auch weniger aufwendig ist, und nehmen dafür evtl. Nachteile (Ertrag, Sortierung) in Kauf. Wir fragten uns, wie groß die Unterschiede zwischen den resultierenden Sortentypen bei Möhren des Nantaise-Typus derzeit sind.

Swiss organic dairy farmer survey: Which path for the organic cow in the future?
Provedor de dados: 21
Autores: Haas, Edda; Bapst, Beat.
The survey showed a high interest of the Swiss organic dairy farmers in breeding, suggesting that there is potential to breed an adapted organic dairy cow. However, it is clear that it would be difficult to breed an “organic dairy cow” that would be suitable for all farms. The differences between farms, particularly between mountain areas and valley regions, were notable. As a result, each farm manager has to specify criteria and breeding goals essential for his or her farm and try to pursue and reach these goals with the available services. Existing tools, like the EBI, are widely considered as helpful, but have to be improved with new knowledge, and further possibilities should be developed.  The modern dairy cow for the organic sector must have a long...

Geitenbrij op een rij: De fokkerijpraktijk in de biologische melkgeitenhouderij nader bekeken, is er gevaar voor inteelt?
Provedor de dados: 21
Autores: Borsten, Jos.
Dit onderzoek had als doel meer inzicht te verschaffen in de praktijk van de biologische geitenfokkerij van Nederland en een indruk te krijgen van de kans op inteelt in deze sector. In de gevonden fokkerijpraktijk is de afstamming van de geiten aan vaderszijde niet goed geregistreerd. Veel geitenhouders lossen dit op door steeds na maximaal twee jaar de bok van het bedrijf af te voeren en nieuwe bokken te kopen. Dit is geen duurzame oplossing omdat de aangekochte bokken direct of indirect van dezelfde fokkers afkomstig zijn. Door middel van een zevenstappenmodel is een inschatting gemaakt van de kans op inteelt. Deze kans ligt op 76,5%. Dit is hoog. Alleen bij het kleine aantal bedrijven met een gesloten fokkerij (= eigen aanfok van bokken) en een totale...

A travers l’exemple du blé dur, les auteurs explorent l’évolution temporelle de la notion d’idéotype mais aussi comment la diversification actuelle des environnements en AB influe sur la diversification des idéotypes et rend nécessaire une démarche dynamique et participative d’amélioration des plantes. Cette façon renouvelée de concevoir et gérer la sélection amène à dépasser la notion d’idéotype, qui reste associée à des critères de sélection a priori, pour préférer le terme de « realtype », qui traduirait la mise à l’épreuve de l’idéotype à la réalité des terrains. Ce n’est donc pas la construction de l’idéotype « par rapport à » mais bien « dans » le contexte qui est recherché et permise par un dispositif collectif représentant la diversité des acteurs...

Auswinterung im Jahr 2011/12: Auswirkungen auf   Winterweizen-Liniensorten und Winterweizenpopulationen in der F10
Provedor de dados: 21
Autores: Brumlop, Sarah; Finckh, Maria R.
TThree winter wheat composite cross (CC) populations were created in 2001 in the UK consisting either of 20 modern wheat parents (called A population), a subset of 12 high quality parents (Q), or a subset of 9 high yielding parents (Y). Seed of the F4 was transferred to the University of Kassel in 2005 and the populations were grown since then under organic and conventional conditions in well separated large (&gt;100 m2) plots in two parallel sets (12 populations total) without conscious selection applied. In the conventional system fungicides and insecticides were not applied to expose the populations to natural pest and disease pressure. In addition, since the F8 two A populations have been maintained as broadcast sown populations without mechanical weed...

Gestalt, Geruch und Geschmack von Weizen im DOK-Anbauvergleichsversuch
Provedor de dados: 21
Autores: Arncken, C.; Weibel, F.P.; Mäder, P.
This project was designed as an iterative process of describing quality profiles of “organic” and “high-quality” wheat and finding adequate, sensory-based methods to do so. Wheat growing in 1998-2000 at the DOK long-term field trial (FLIEßBACH et al. 2007, MÄDER et al. 2002) was repeatedly investigated. The ripening phase started earlier and lasted longer in treatment D2 (bio-dynamic) and was shortest in treatment K2 (conventional). Coded grain samples were examined in respect to treatment differ-ences in smell and taste. For D2 samples the author used the highest number of “sweetness” terms and the lowest number of other terms, whereas in M (conven-tional/mineral fertilizer only) grains, the highest numbers of “poorness” terms and the lowest of...

Samengestelde kruisingspopulaties: alternatief veredelingsconcept in granen?
Provedor de dados: 21
Autores: Temmerman, Femke.
Gewassen hebben nood aan een zekere genetische diversiteit om zich optimaal te kunnen aanpassen aan wijzigende groeiomstandigheden. Dit wordt vaak benoemd als de ‘weerbaarheid’ of de ‘robuustheid’ van een gewas of een ras. Dit is al langer bekend in gebieden met zeer uitgesproken stressfactoren zoals bodemvruchtbaarheid of klimaat. Ook bij zeer wisselende klimaatsomstandigheden, zoals wij deze meer en meer ervaren in onze gematigde klimaatzone, wint dit gegeven mogelijk aan belang. In de biologische landbouw wegen de feitelijke en plaats specifieke groeiomstandigheden (nutriënten, vocht, ziekte,…) nog sterker door dan in de gangbare teelt, waar met bemesting en gewasbescherming de groeiomstandigheden gestandaardiseerd worden.

Concepts and Strategies of Organic Plant Breeding in Light of Novel Breeding Techniques
Provedor de dados: 21
Autores: Nuijten, Edwin; Messmer, Monika M.; Lammerts van Bueren, Edith T.
In this paper, we describe the development of a set of guiding principles for the evaluation of breeding techniques by the organic sector over time. The worldwide standards of organic agriculture (OA) do not allow genetic engineering (GE) or any products derived from genetic engineering.  The standards in OA are an expression of the underlying principles of health, ecology, fairness and care. The derived norms are process and not product oriented. As breeding is considered part of the process in agriculture, GE is not a neutral tool for the organic sector. The incompatibility between OA and GE is analyzed, including the “novel breeding techniques”. Instead, alternative breeding approaches are pursued based on the norms and values of organic agriculture not...

La production de tomate biologique tient une place importante sous abri froid en Provence. Le choix variétal est limité aux variétés disponibles en semences biologiques ou non traitées.   En circuit long, la filière impose des caractéristiques similaires à celles du marché conventionnel : bonne fermeté, forme et coloration régulières, absence de défaut visuel; le choix variétal s'oriente donc vers des variétés "classiques", de type mid-life : Brenda et Paola (semences biologiques), Pétula (semences non traitées) … qui assurent un bon rendement commercial (faible taux de déchets) et présentent de nombreux gènes de résistances aux maladies, mais dont la qualité gustative est souvent décevante.

Das Angebot an samenfesten Sorten des Chinakohl für den Erwerbsgartenbau ist praktisch gleich null. Um für den ökologischen Landbau Alternativen zur zunehmend kritischer betrachteten Hybridzüchtung zu erhalten, wurde während einer dreijährigen Projektlaufzeit versucht, fünf samenfeste Chinakohlsorten mittels Restsaatmethode und Prüfung von Einzelpflanzennachkommenschaften in Homogenität und Wertigkeit weiterzuentwickeln. Die Restsaatmethode, also das Zurückgreifen auf Saatgut, dessen Nachkommen bewertet wurden, erscheint bei Chinakohl als praktikabler Weg für die Züchtung, da eine Überwinterung von Elitepflanzen äußerst verlustreich ist.  Es zeigte sich bei den fünf Sorten eine sehr unterschiedliche Entwicklung in der Wertigkeit, doch konnte aufgezeigt...

Autores: Blum, Hanna; Fausten, Gudrun; Nega, Eva; Jahn, Marga; Gaerber, Ute; Aedtner, Ina.
As in vegetable growing or grain cropping the seed quality is an important factor for the successful cultivation of medicinal plants and herbs. In spite of intensive efforts made by specialised seed producers there are recurring problems with important quality parameters (e.g. germination capacity, emergence or seed health). The lack of sufficient study results is typical for special purpose crops, also concerning the particular host-parasite relationship and its methodical verification. Few experiences with the improvement of seed quality of medicinal plants and herbs are available. The intention of the study is to test physical and biological methods of seed treat-ment for their practicability in medicinal plants and herb cultivation. Fundamental...

Charakterisierung der Resistenz von Winterweizensorten gegenüber Steinbrand (Tilletia caries)
Provedor de dados: 21
Autores: Wächter, Dr. Rebecca; Wolf, Dr. Gerhard; Koch, Dr. Eckhard.
Attack with common bunt (Tilletia caries) is a potential threat to wheat production in organic farming. The situation may even become worse if (in agreement with EU-legislation) only organically produced seed is used in organic farming. The targeted use of resistant varieties could be a way to alleviate the problem. However, knowledge regarding bunt resistance of wheat varieties on the one hand and aggressiveness in populations of the bunt pathogen on the other hand is still insufficient. In the frame of a federal research programme for organic farming (BÖL),30 winter wheat varieties and breeding lines were studied at five different locations using spores of local origin in order to assess the natural level of resistance (WÄCHTER et al. 2004).

Due to fast spread of genetically modified (GM) Bt-cotton, organic farmers in India were suddenly exposed to a severe shortage of non-GM seed threatening the organic cotton production. Therefore, organic cotton grower organisations got engaged in decentralized participatory cotton breeding to develop their own locally adapted cultivars and to reintroduce the traditional more robust Desi cotton species. By engaging and training advisors and farmers using participatory methods, they became researchers and breeders. The close collaboration with the textile industry ensures that the market demand is also met. Training of male and female farmers in cultivar selection and seed propagation made them independent from global seed companies. Participatory breeding...

This study compared physical and sensory quality traits of three breeding lines and one hybrid of organic broccoli to find suitable open pollinating variety with high  potential for marketability. An Instron texture analyzer was used to measure the firmness of the texture. Descriptive and hedonic tests were done to assess sensory quality. The evaluation of the genotypes by the panelists showed a trend to rank the lines as “good” in respect to their sensory properties and their outer appearance. CHE-MIC-31 was the firmest open pollinating genotype. Results of this study showed that this breeding line has the potential for marketability because of it’s superior physical and sensory attributes.

Adapted vs. conventional cattle genotypes: sustainability for organic and low input dairy production systems
Provedor de dados: 21
Autores: Zollitsch, Werner; Ferris, Conrad; Sairanen, Auvo; Rinne, Marketta; Steinwidder, Andreas; Horn, Marco; Moorby, Jon; Vestergaard, Mogens.
Dairy cow strains arising from conventional breeding programmes are frequently perceived as unsuitable for organic and low input milk production systems. While farmers have identified a number of breeds and strains as being ‘adapted’ to organic and low input systems, there is often little scientific evidence to indicate that these breeds are more appropriate than conventional genotypes.  Thus the purpose of this study is to examine the response of different dairy genotypes (i.e. "conventional" versus "adapted") to an undersupply with nutrients and energy, which is a characteristic of low input systems with limited dietary supplementation and to provide information on the metabolic response of dairy cows to such dietary restrictions.

Die Pastinake hat seit geraumer Zeit an Bedeutung verloren, obwohl sie als sehr ertragreiche und widerstandsfähige Wurzelgemüseart gilt. Dies liegt wohl am strengen Geschmack und/oder am unangenehmen Geruch, den die Pastinake beim Kochen verströmt. Auch die geringe Dauer der Keimfähigkeit des Saatgutes ist einem umfangreichen Anbau dieser Gemüseart nicht zuträglich. Heute finden sich in vielen Sortenherkünften aus Handel und Genbank die unterschiedlichsten Formen, d.h. die Sorten sind häufig sehr heterogen geworden.

A longer life for laying hens is desired from an ethical point of view. Not only because the hens can be used for a longer period but also less male chicks would have to be killed at the age of one day. In large flocks of laying hens moulting has to be induced to prevent social instability in the flock. In this study, a method was investigated, to moult laying hens without too much stress for the hens. The chosen method with daily access to a bad weather hen run had no detectable negative effect on the behaviour of the hens. The moulting succeeded in improving egg quality and plumage condition.

Wheat populations: population performance and stability in organic and non-organic environments
Provedor de dados: 21
Autores: Wolfe, Prof. Martin; Boyd, Ms Helen; Clarke, Dr Sarah; Haigh, Ms Zoe; Jones, Dr Hannah.
Twenty winter wheat varieties were used as parents in a half diallel crossing programme for the production of wheat populations and physical mixtures that were then grown in field trials at two non-organic and two organic sites over three years in England. Yields of the populations and mixtures were compared with those of the relevant varieties grown as pure stands. In general, there was an improvement in yielding ability in the populations which was achieved while maintaining a high level of stability across environments. Potential improvements through selection or introduction of broader based populations are discussed.

Swiss Brown Swiss in different environments: Does GxE play an important role?
Provedor de dados: 21
Autores: Bapst, Beat.
Estimations of genotype by environment interactions have been carried out for Brown Swiss dairy cattle in Switzerland. Yield traits were considered as different traits in different environments. Genetic correlations were then estimated for the same trait in different environments.  First results from bivariate analyses showed that genotype by environment interactions might exist in the investigated population, especially for fat yield and protein yield. Further analyses are needed to prove genotype by environment interactions in Brown Swiss cattle in Switzerland.

Comparison of performance and fitness traits in German Angler, Swedish Red and Swedish Polled with Holstein dairy cattle breeds under organic production
Provedor de dados: 21
Autores: Bieber, A.; Wallenbeck, A.; Spengler Neff, A.; Leiber, F.; Simantke, C.; Knierim, U.; Ivemeyer, S.
Although the use of local breeds is recommended by organic regulations, breed comparisons performed under organic production conditions with similar production intensities are scarce. Therefore, we compared data of local and widely used Holstein dairy cattle breeds from 2011 to 2015 regarding production, fertility and health from German and Swedish organic farms with similar management intensities within country. In Germany, the energy-corrected total milk yield tended to be lower in the local breed Original Angler Cattle (AAZ, 5193 kg) compared to the modern German Holstein Friesian breed (HO, 5620 kg), but AAZ showed higher milk fat and protein contents (AAZ v. HO: 5.09% v. 4.18% and 3.61% v. 3.31%, respectively). In Sweden, the widely used modern...

Neue Züchtungsstrategien für den ökologischen Salatanbau
Provedor de dados: 21
Autores: Gärber, Ute; Behrendt, Ulrike.
The increasing demand of organically produced lettuce can only be met by enlarging the assortment and stabilizing the yield. Cultivating lettuce of a high quality safely  requires varieties with improved stress tolerance, a well-developed ability to utilize nutrients, a low demand of water, as well as a high resistance to pathogens,  particularly to downy mildew. Planting mixtures might be seen as an alternative method to present pure varieties. The results of four-year studies in the field in three  locations showed that line mixtures reacted in a far more stable way to stress factors than pure varieties. The diversity in cultures is promoted by mixing so that the  variation of resistance can be exploited to control diseases. Total losses caused by Bremia...

Autores: Shetty, Nisha; Janss, Luc; Zaalberg, Roos Marina; Kargo, Morten; Buitenhuis, Albert Johannes.
In this paper we present the results of a genome-wide association study to identify significant genes that contribute to genetic variation in abundant milk fatty acids (FAs) C14:0 and C16:0 with considering lactation stage effect. FA composition phenotypes were measured using Application Note 64 (FOSS) and were available on 24,661 milk samples from 3,213 Danish Holstein cows. Association mapping analyses was performed using a Bayesian Variable Selection method. Results showed, in total 21 significant SNPs were detected for C14:0 and 18 significant SNPs were detected for C16:0 that are significant in changing over lactation stage for abundant milk FAs C14:0 and C16:0. For both milk FAs most significant SNPs influencing the slope of the lactation curve were...

Organic farming systems are characterized by reduced nitrogen supply. Nitrogen (N) is one of the most important yield limiting factors and an essential component for proteins. For organic farming cereal varieties with high N use efficiency are required. The main components of N use efficiency are N uptake and N utilization efficiency. Triticale has shown to be very suitable for organic farming due to its tolerance to marginal conditions and high competition against weeds. Little is known about N use efficiency and its components in triticale. The aims of the study were to i) analyze the influence of N uptake and N utilization efficiency for improved N efficiency, ii) estimate quantitative genetic parameters for N uptake and N utilization efficiency, and...

BackgroundWorldwide, India is the most important country for organic cotton production with 67% market share. In India, organic cotton production is challenged by 95% genetically modified (GM) cotton cultivation.Public breeding and seed multiplication were neglected and local non-GM seeds supply were eroded. With the continuous growth of the organic market it is important to maintain non-GM germplasm, to enlarge the offer of organic cultivars with a better performance that meet the demand of the market, and to rebuild the seed sovereignty of organic smallholder cotton farmers. Participatory breeding of Gossypiumhirsutumand traditionalG. arboreumcotton offers a great opportunity for developing locally adapted cultivars for increasing genetic diversity.

Autores: Stauss, R.
Ecological intensification of agricultural practices can be a minimum input agriculture with a maximum utilization of the epigenetic potential for a maximum output.  The application of Quantitative Population Epigenetics as a catalyst for sustainable agriculture offers earning opportunities (market segments or business cases) for the existing players in the high-input agriculture in terms of win-win.  For example, agriculture is a major factor in eutrophication of surface waters. By using epigenetically active compounds to switch on yield or stress genes, new crop varieties for low-input agriculture could be developed to improve nitrogen and water use efficiency for cereal production significantly.

Evolutionary plant breeding in cereals– into a new era
Provedor de dados: 21
Autores: Döring, Thomas; Knapp, Samuel; Kovacs, Geza; Wolfe, Martin.
In evolutionary plant breeding, crop populations with a high level of genetic diversity are subjected to the forces of natural selection. In a cycle of sowing and re-sowing seed from the plant population year after year, those plants favored under prevailing growing conditions are expected to contribute more seed to the next generation than plants with lower fitness. Thus, evolving crop populations have the capability of adapting to the conditions under which they are grown. Here we review the current state of research in evolutionary plant breeding and concentrate on the ability of evolving plant populations to deal with stressful, variable, and unpredictable environments. This resilience of evolving plant populations is seen as a major advantage under...

As organic farmers are searching for new market and sale opportunities, the organic farming system may grow and process a wider range of species than the conventional farming system. Concerning wheat especially the hulled wheat species einkorn, emmer wheat and spelt wheat are in recent years of growing interest for organic farmers. Field trials were carried out at three Czech locations from 2009 to 2010 to study the performance of 4 einkorn, 8 emmer wheat and 7 spelt wheat accessions. All trials were spring sown and bread wheat variety SW Kadrilj was used as check. The results show that some accessions of the hulled wheat species are inclined to lodging. On the other hand, they are resistant to foliar diseases, e.g. powdery mildew and leaf rust. Hulls...

Macroscopic leaf symptoms in wheat infected by Tilletia tritici
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
Common bunt (Tilletia tritici) infects the wheat plant during germination of the seed. For experiments with common bunt it is conventional to examine symptoms of infection in the head of the plant. Previous research has advocated the possibility of scoring chlorosis on the leaf instead of head symptoms in order to reduce the duration of the experiment. By comparing the two diagnosis methods in climate chambers, the current experiment demonstrated that the sensitivity and specificity of the two methods depends on the wheat variety used. Using leaf symptoms as a diagnosis for infection has considerable disadvantages when used for screening for resistance in breeding programs, but have advantages e.g. when investigating effects of seed treatments.

Four DNA markers associated with Cd concentration were found: two RAPDs (random  amplified polymorphic DNAs), one REMAP (retrotransposon-microsatellite amplified  polymorphism), and one SRAP (sequence-related amplified polymorphism). The  markers were assigned to one linkage group which exhibited a QTL (quantitative trait  locus) representing a major gene for Cd accumulation. The markers can be used in  future breeding programmes for healthy oat cultivars.

Participatory cotton breeding for organic and low input farming in Central India
Provedor de dados: 21
Autores: Roner, T.; Messmer, M. M.; Finckh, M.; Forster, D.; Verma, R.; Baruah, R.; Patil, S. S.
Up to 80% of world’s organic cotton is produced in India. However, involved producers are facing increased difficulties to find suitable cultivars. Few hybrids selected for high input farming and genetically-modified (GM) cotton, which is explicitly excluded in organic farming, are presently dominating the Indian seed market. In addition farmers have lost their traditional knowledge on seed production and hybrid seed needs to be purchased each season.

Sind Ökotypen von Welschem Weidelgras für den Ökolandbau  besser geeignet als Zuchtsorten?
Provedor de dados: 21
Autores: Boller, Dr. Beat; Schubiger, Dr. Franz Xaver; Tanner, Peter.
Ten ecotype populations of Italian ryegrass collected in permanent grassland in  different regions of Switzerland were compared to two currently recommended  cultivars in plot trials under both organic and conventional conditions. On average, the  ecotypes had similar yields as the cultivars under organic conditions, but significantly  outyielded them under conventional conditions. However, some of the best ecotype  populations appeared to be also very suitable for organic agriculture. All ecotypes  were extremely susceptible to crown rust. Therefore, targeted selection is needed to  exploit their potential for use in organic agriculture.

Epidemiology of dark leaf spot caused by Alternaria brassicicola in organic seed production of cauliflower
Provedor de dados: 21
Autores: Köhl, J.; van Tongeren, C.; de Haas, B.H.; Driessen, R.G.
Dark leaf spot caused by Alternaria brassicicola is a seed-borne disease of Brassicae. Production of healthy seed is essential for the organic vegetable production. Literature on the epidemiology of the disease in organic seed production of Brassica was reviewed and an epidemiological field experiments was carried out. External and internal contamination of seeds with A. brassicicola increased steadily during their development. Colonisation of pod tissues as quantified by TaqMan-PCR increased exponentially. The developed knowledge can be used for optimizing cropping systems for organic seed production with lower risks for seed contamination by Alternaria spp. and to develop critical control points for disease management.

In organic agriculture site related factors of animal environment can’t be changed to a great extend by using remedies like additional food, concentrates and medicines as it is common in conventional agriculture. Therefore site related environment factors have a great influence on the possibilities of dairy cow breeding and husbandry on an organic farm. Non site related animal breeding can elevate the risk of (metabolic) stress and diseases in cows. The goal of this project was to introduce a new tool for advisers and farmers to estimate and ameliorate the site relatedness of dairy cow breeding and husbandry. The tool should help to characterize and compare “farm types” and “dairy cow types” and to judge if they fit together or not. 12 site related factors...

Detailed milk fatty acid profiling of the Danish dairy cattle population
Provedor de dados: 21
Autores: Poulsen, Nina Aagaard; Hein, Lisa; Gregersen, Sandra Beyer; Sørensen, Lars Peter; Larsen, L.B.; Kargo, Morten; Buitenhuis, Albert Johannes.
Abstract  Milk fatty acid (FA) composition can be manipulated through feeding, and especially effects of grazing have been shown to promote a healthier milk FA profile due to increasing contents of beneficial FAs, like conjugated linoleic acid (CLA) and α-linolenic acid (C18:3, the main n3 FA in milk). In addition to diet-based manipulations, selective breeding for specific FA could also be a strategy for altering the FA profile as milk FA display low to moderate heritabilites (0.07-0.34 in Danish Holstein).  Since 2015, milk samples from all Danish dairy cows under yield control have been analyzed using mid infrared spectroscopy. The FOSS Application Note 64 has subsequently been used to predict content of seven FA groups (short-chain FA (SCFA),...

Autores: Lammerts van Bueren, Edith T.; Struik, Paul C.; Eekeren, Nick van; Nuijten, Edwin.
How the growing world population can feed itself is a crucial, multi-dimensional problem that goes beyond sustainable development. Crop production will be affected by many changes in its climatic, agronomic, economic, and societal contexts.  Therefore, breeders are challenged to produce cultivars that strengthen both ecological and societal resilience by striving for  six international sustainability targets: food security, safety and quality; food and seed sovereignty; social justice;  agrobiodiversity; ecosystem services; and climate robustness. Against this background, we review the state of the art in plant  breeding by distinguishing four paradigmatic orientations that currently co-exist: community-based breeding, ecosystem-based  breeding,...

Differences in Yield Parameters of Emmer in Comparison with Old and New Varieties of Bread Wheat
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different localities in the Czech Republic. Results of the research were compared to characteristics of four old and two top  modern bread wheat (Triticum aestivum L.) cultivars. The emmer wheat varieties were resistant to usual wheat diseases. They formed their yield by a quantity of productive tillers (2.5), whereas the varieties of bread wheat had less productive tillers...

Autores: Brumlop, Sarah; Finckh, Maria R.
Introduction  In order to be able to adapt to changing environmental conditions, crop plants need a certain degree of diversity (Stevens 1942, Finckh 2008). The development of genetically diverse populations (composite cross populations, CCPs) instead of breeding entirely homogeneous pure line varieties by standard pedigree breeding methods is a strategy that aims at creating flexible varieties.   Material and Methods   Three winter wheat CCPs from the UK based on 20 modern wheat varieties (A) or a subset of either 12 high quality varieties (Q) or 9 high yielding parents (Y) were used. Since the F5 the CCPs have been grown under organic (O) and conventional (C) conditions in two parallel sets at the University of Kassel without artificial selection...

173 skulls of Swiss Brown dairy cows (horned=65, disbudded=165) were osteometrically sized. The greatest post-orbital width and the longitudinal height of the foreheads were recorded. The shape of the frontal bone was scaled into three categories: waveform, pointed, and straight. There was no significant influence of age on skull narrowness. More narrow skulls could be observed in dehorned cows than in horned cows. Dehorned cows had more pointed skull shapes, less waveform shapes, and less straight skulls. Whether these anatomic variances affect the wellbeing of cattle and how this alteration is exactly proceeding during growth should be examined in further studies.

Autores: Lammerts van Bueren, E.T.; Nuijten, E.H.A.C.P.; Tiemens-Hulscher, Marjolein.
Is er een voordeel te behalen als de selectie van uien voor de biologische teelt ook onder biologische omstandigheden gebeurt, in vergelijking met gangbare selectieomstandigheden? Deze vraag is opgepakt met twee brede basispopulaties (Ronde Rijnsburger Groep en Platte Groep) en het zaadvaste ras Balstora. Er is een trend zichtbaar dat biologische selecties onder biologische omstandigheden een betere opbrengst geven, en gangbare selecties onder gangbare omstandigheden.

Breeding for specific bioregions: a genotype by environment study of horticultural and nutritional traits integrating breeder and farmer priorities for organic broccoli cultivar improvement
Provedor de dados: 21
Autores: Renaud, E.N.C; Lammerts van Bueren, E.T.; Jiggins, J.; Maliepaard, C.; Paulo, J.; Juvik, J.A.; Myers, J.R.
The genotype by environment interaction study of broccoli,  amongst others  demonstrates that traits of a cultivar are sometimes ranked differently when grown in an organic production system compared to a conventional system. This has strong implications for breeding strategies. The breeders interviewed acknowledged that more attention on abiotic and biotic stress resistance in a broccoli breeding programme is needed which is in accordance with the farmers' varietal requirements. The first findings of the field trials show that cultivar performance is influenced by season and region, and differences in treatment (organic versus conventional management). The field trials showed that there are cultivars with broad adaptation such as "Green Goliath". These...

Qualitative und quantitative Beurteilung des Verhaltens von Jungsauen während eines freiwilligen Annäherungstests
Provedor de dados: 21
Autores: Pfeiffer, Christina; Leeb, Christine; Winckler, Christoph.
Free farrowing systems are required by organic standards (Commission regulation (EC) 889/2008). However, not only adequate housing design and good management but also sows which are able to rear piglets successfully in those systems are important. Several studies show a relation between approach time during behavioural tests and reproductive traits. So far behavioural traits are not considered when selecting gilts in Austria. The aim of this study was to perform a qualitative and quantitative behavioural assessment during a voluntary approach test at two organic gilt producers which could provide practical tools for behavioural assessment when selecting gilts. A total of 44 gilts was tested in a 3x3m arena and observed when approaching a test person....

Epigenetics and organic plant breeding
Provedor de dados: 21
Autores: Messmer, Monika.
One characteristic of process oriented organic plant breeding is that all breeding activities from the initial crosses up to final variety propagation are performed under organic growing conditions, allowing the plant to interact with its target environment across all generations. However, it is often argued that it is sufficient to select under conventional farming and test the released varieties under organic farming conditions.

Organic plant breeding and propagation: concepts and strategies
Provedor de dados: 21
Autores: Lammerts van Bueren, Edith.
The organic farming system differs fundamentally from conventionally agriculture in the management of soil fertility,weeds,diseases and pests.Organic farmers depend greatly on conventionally bred and produced varieties,but require varieties better adapted to organic farming systems for further optimisation of organic agriculture.This includes a greater need for ‘reliable ’ varieties contributing to higher yield  stability.  In this thesis the concept of ‘naturalness ’ as applied in organic agriculture is elaborated and used as a guide to develop concepts and strategies for organic plant breeding and propagation.It refers to ecological and ethical principles,including the non-chemical and agro-ecological approach,and also taking the integrity of life into...

Participatory Plant Breeding Concept as Tool for Creating Adapted Varieties for Local Conditions
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Janovska, Dagmar.
Organic farming has been developing worldwide over the last few decades. However, the crucial problem has not been resolved yet – a lack of suitable varieties. It is a serious factor limiting this development. Breeding is a very demanding and expensive process; special varieties are not bred for the organic farming from many crops then. A concept called "participatory plant breeding“ (PPB) is a possibility for resolving this problem. It is based on a direct involvement and participation of a farmer in the breeding process. Undemanding and cheap breeding methods are chosen there – they do not require any special education or equipment from the farmers involved. Training and professional surveillance are sufficient there. One of PPB methods has been already...

It cannot be generally recommended to use older varieties unless quality aspect are reflected in the price, but some old varieties were compatible with the commonly grown modern varieties. The results calls for targeted breeding for low input conditions, as breeding for high input condition contribute little to the benefit of organic agriculture and other low input conditions. Research is needed to quantify the effect of the different yield components of breeding on grain and straw yield and quality at low input conditions.

State of organic seeds in France
Provedor de dados: 21
Autores: Rey, F; Sinoir, N.; Wohrer, J.; Touret, C.; Mazollier, C.
A comprehensive range of investigations carried out between 2010 and 2012 provided information on the state of organic seeds in France. Results fit with the hypothesis that the market is a significant factor influencing the choice of seeds and cultivars (local cultivars, landraces, modern cultivars). Expectations and practices of producers selling on a local market (i.e., direct sale) differ radically from those of producers selling to long food supply chains.  This study showed that the availability and use of organic seeds have significantly improved over the last three years. A vast majority of organic producers willingly use organic seeds, with, on average, 45-70 % (cereals), and 75%-100 % (vegetables) of organic seeds being planted on farms. However,...

Zusammenfassung  Analog zum Ökologischen Gesamtzuchtwert (ÖZW) für Bullen wurde Ende 2008 erstmals ein ÖZW für Kühe berechnet und den ökologischen Milchviehbetrieben in Bayern mit dem Jahresabschluss der Milchleistungsprüfung zur Verfügung gestellt. Der ÖZW unterscheidet sich vom konventionellen Gesamtzuchtwert (GZW) hauptsächlich durch die deutlich stärkere Gewichtung der Fitnessmerkmale. Während bei der Zucht nach GZW der erwartete Selektionserfolg überwiegend in der Milch- und Fleischleistung liegt, wird bei der Selektion nach ÖZW, neben einer moderaten Verbesserung der Leistung, eine deutliche züchterische Verbesserung der Fitnessmerkmale angestrebt.  Der ÖZW für Kühe sowie die Teilzuchtwerte Leistung und Konstitution ermöglichen dem ökologisch...

Breeding strategies in poultry for genetic adaptation to the organic environment
Provedor de dados: 21
Autores: Sørensen, Poul.
Regarding access to breeding material for laying hens to organic egg production the following can be concluded:  The breeding material available is genetically adapted to the cage systems. This cage adapted material has a shortcoming regarding behaviour in larger flocks that manifest in: too high tendency to feather pecking and cannibalism, and, independent of flock size, also to many mislaid eggs. Experiments has shown that feather pecking, cannibalism and nesting behaviour can be improved by selection. A search for alternative breeds/hybrids has not yet given the ideal "Organic hen". There seem to be a possibility for adaptation of laying bird to diets with lower crude protein that makes a production possible based on "home grown" crops even in Northern...

Anders als bei Rindern und Schweinen ist die künstliche Besamung (KB) in der deutschen Ziegenzucht bislang ein kaum übliches Verfahren. Hauptursachen dafür sind der Umfang und die Strukturen der Zuchtpopulationen sowie die wirtschaftlichen Rahmenbedingungen für die Züchter. Andere Länder wie Frankreich, Schweiz, Spanien oder auch Schweden zeigen jedoch, dass durch konsequente Besamungszucht der züchterische Fortschritt erheblich gesteigert werden kann. Durch den Spermaeinsatz verschiedener Vatertiere kann wirksam der Inzuchtproblematik im Bestand begegnet werden. Gerade Halter kleinerer Bestände können so ohne eigenen Bock, dessen Geruchsbelästigung nicht zu unterschätzen ist, ihre Herde optimal reproduzieren. Ein genauso wichtiges Argument für die...

Estimation of genetic parameters for novel functional traits in Brown Swiss cattle
Provedor de dados: 21
Autores: Kramer, M.; Erbe, M.; Bapst, B.; Bieber, A.; Simianer, H.
The aim of this study was to estimate genetic parameters and accuracies of breeding values for a set of functional, behavior, and conformation traits in Brown Swiss cattle. These traits were milking speed, udder depth, position of labia, rank order in herd, general temperament, aggressiveness, milking temperament, and days to first heat. Data of 1,799 phenotyped Brown Swiss cows from 40 Swiss dairy herds were analyzed taking the complete pedigree into account. Estimated heritabilities were within the ranges reported in literature, with results at the high end of the reported values for some traits (e.g., milking speed: 0.42±0.06, udder depth: 0.42±0.06), whereas other traits were of low heritability and heritability estimates were of low accuracy (e.g.,...

Möglichkeiten der genomischen Selektion für neue funktionale Merkmale
Provedor de dados: 21
Autores: Kramer, Michael; Bieber, Anna; Bapst, Beat; Simianer, Henner.
Ziel dieser Arbeit war es, genetische Parameter für neue funktionale Merkmale beim Schweizer Braunvieh zu schätzen. Für Melkgeschwindigkeit und Verhaltensmerkmale wurden insgesamt hohe Heritabilitäten geschätzt, obwohl diskrete, subjektive Skalen Anwendung fanden. Der Grund dafür liegt in der gewissenhaften Anwendung dieser Skalen durch die Landwirte. Eine exakte Messung der Eutertiefe in cm über dem Sprunggelenk führte ebenfalls zu einer beachtlichen Heritabilität. Daraus ergeben sich hohe Genauigkeiten der konventionellen Zuchtwerte phänotypisierter Kühen. Dieses bringt große Vorteile bei der Verwendung gemischter Trainingssets aus nachkommen geprüften Bullen und phänotypisierten Kühen in der genomischen Selektion.

The specific aims were (1) to investigate the presence of heterogeneity in farmers’ preferences by means of cluster analysis, and (2) to associate these clusters with herd characteristics and production systems (organic or conventional). We established a web-based survey to characterize the preferences of farmers for improvements in 10 traits, by means of pairwise rankings. We also collected a considerable number of herd characteristics. Overall, 106 organic farmers and 290 conventional farmers answered the survey, all with Holstein cows. The most preferred trait improvement was cow fertility, and the least preferred was...

Børsterensning kan reducere stinkbrand i hvede
Provedor de dados: 21
Autores: Borgen, Anders.
Stinkbrand i hvede (Tilletia tritici) er tilstede i såsæden som frie svampesporer. De enkelte kerner er ikke inficerede ved høst, men efter såning spirer sporerne samtidig med kornet, og de fremspirende planter bliver så inficeret af svampen. Stinkbranden kan derudover også være til stede i såsæden som brandbutter, det vil sige de kornlignende sporefyldte sori, som sygdommen danner i hvedeakset.

Standortanpassung durch Nachbau und Auslese im landwirtschaftlichen Betrieb – eine Studie mit Landsorten der Linse
Provedor de dados: 21
Autores: Horneburg, Dr Bernd.
Agrobiodiversity and the on-farm production of seeds have been decreasing on a glo-bal scale during the past century. The concept of an organic farm as a self contained organism requires an entirely different development: Decentralized organic breeding can achieve an adaptation to local pedoclimatic conditions and preferences. Until now very little research has been carried out into the mechanisms and prospects of local adaptation fostered by breeding and maintaining varieties on farm.  To gain additional knowledge field trials were carried out in three farms during three years. Three lentil (Lens culinaris Medik.) landraces were subjected to natural selec-tion, positive mass selection, and progeny testing. Agronomic, morphological, and phenological traits...

Participatory Plant Breeding for Organic Farming in France, the cauliflower experience at the PAIS
Provedor de dados: 21
Autores: Chable, Dr Véronique; Le Lagadec, François.
The availability of organic seeds is a great problem for organic farmers. The private sector of plant breeding meets difficulties to answer to the organic farming (OF) demand, characterized by small quantities and a great diversity of criteria and by breeding methods which respect the natural species characteristics (see IFOAM Draft Standard on organic seeds and plant breeding). So, the organic sector is organizing breeding and seed production by itself    In France, since 2001, a Brittany regional organic umbrella (IBB, Inter Bio Bretagne), and some researchers from the national institute for agronomical research (INRA) have initiated a breeding program for organic production and a participatory plant breeding (PPB) program for organic cabbages and...

Against the grain
Provedor de dados: 21
Autores: Döring, Thomas F.; Crowley, Oliver; Wolfe, Martin.
An Organic Research Centre project is examining how diversity-based tools can assist in the on-farm improvement of organic wheat.  Successful organic crop production requires varieties that are resistant to diseases, competitive against weeds, and effective at scavenging nutrients. Yet conventional plant breeding has largely neglected organic systems by breeding varieties exclusively for high input conditions. As a consequence, organic producers currently do not have enough choice of plant varieties for organic conditions.  One way to expand the choice is to create plant diversity anew and subject it to natural selection on organic farms.  After several generations the dominating plants would be better suited to organic systems. This idea is being tested...

Comparison of interconnections between barley breeding material traits under organic and conventional growing conditions
Provedor de dados: 21
Autores: Legzdina, L.; Kokare, A.; Beinarovica, I.; Lammerts van Bueren, Edith T.
While breeding for organic farming it is necessary to identify the most appropriate growing  conditions in which to perform the selection process. Soil fertility, crop management, yield level  and other factors may vary very much between each organic farm, and between organic farms and  research institutions where the selection is usually performed. Since plant breeding requires  considerable input of resources and the market for organic varieties is limited, it is essential to find  the most appropriate selection conditions that will provide acceptable varieties for organic farms.  Spring barley breeding lines selected from two cross combinations (Primus/Idumeja and  Anni/Dziugiai) at two distinctive organic and two conventional locations were used in the...

Neue Züchtungsstrategien bei Salat zur Anpassung an ökologische Anbaubedingungen und Verbesserung der Resistenz gegen Bremia lactucae
Provedor de dados: 21
Die Anbaufläche verschiedener Salatformen ist in den vergangenen Jahren kontinuierlich gestiegen. Ware aus ökologischem Anbau ist dabei stark gefragt. Am Markt fehlen jedoch Sorten verschiedener Salatformen, die eine große Anbausicherheit im ökologischen Anbau mit einer guten Produktqualität vereinen. Neben guten geschmacklichen Eigenschaften sollen die Sorten eine hohe Stresstoleranz gegenüber abiotischen Faktoren, gutes Nährstoffverwertungsvermögen und eine hohe Widerstandsfähigkeit gegenüber Schaderregern aufweisen. Besondere Bedeutung kommt dabei der Resistenz gegenüber dem Erreger des Falschen Mehltaus, Bremia lactucae, zu, der äußerst variabel ist und vielfach hochvirulente Erregerformen bildet, die auch Sorten mit monogenen Resistenzen befallen.

Die Eu-Öko-Verordnung 2092/91 sieht auch für den Weinbau die Verwendung von ökologischem Pflanzgut vor. Eine Ausnahmegenehmigung erlaubt die Verwendung von konventionellem Pflanzmaterial, sofern nachgewiesen ist, dass biologisches Pflanzmaterial auf dem Markt nicht zu erhalten ist. Diese Ausnahmeregelung ist im ökologischen Weinbau derzeit anwendbar, weil europaweit fast kein ökologisches Rebpflanzgut verfügbar ist.

Greenhouse screening for Fusarium wilt resistance in lupine
Provedor de dados: 21
Autores: Kuptsou, N.; Christiansen, J.L.; Raza, S.; Joernsgaard, B.
Fusarium wilt can cause total crop failure. Evaluation of Ffusarium resistance in heavily infected soil were performed in a grenhouse where the dominant fusarium species in the soil in descending order was F. oxysporum then F. avenaceum, F. culmorum, F. solani, F. gibbosum. Large fusarium wilt presure was observed and fully susceptible lines were completely destroyed by Fusarium wilt caused by F. oxisporum. Segregation in F2 and F3 in L. angustifolius showed that resistant genotypes have two dominant non-allelic resistance genes to wilt. We call this gene Relation to fusarium oxisporum (Rfo1,Rfo2). Susceptible genotypes have either two wild genes (++ ++) or one wild and one dominant resistant gene (++ Rfo2 Rfo2, or Rfo1Rfo1 ++). Crossing  ‘++ Rfo2Rfo2’  to...

Adaptation of lupins for Northern European maritime conditions
Provedor de dados: 21
Autores: Joernsgaard, B.; Christiansen, J.L.; Kuptsov, N.
Lupin as a grain crop has been restricted in growing area to more continental conditions due to their indeterminate growth form, which in maritime Northern European areas causes excessive vegetative development, late and uneven ripening and lodging. However, new reduced branching types provides better possibilities for adaptation to these conditions, and preliminary results indicates potential seed yields up to 5-6 tons per ha in the narrowed leafed lupins (Lupinus angustifolius) and an acceptable stable and early ripening. Due to full susceptibility to anthracnose (Colletotrichum gloeosporioides) in white (L. albus) and yellow (L. luteus) their introduction in these environments is doubtful. In these growing areas Botrytis (Botrytis cinerea) and fusarium...

Possibilities for breeding to improve responsiveness to arbuscular mycorrhizal fungi in onion
Provedor de dados: 21
Autores: Galvan, Mr Guillermo; Burger-Meijer, Mrs Karin; Kuyper, Prof Dr Thom; Kik, Dr Chris; Scholten, Dr Olga E.
Arbuscular mycorrhizal fungi (AMF) play an important role in the uptake of nutrients and water from soil. However, some crops, for example onion, Allium cepa L., have a poorly developed root system. As a result, onion plants need a lot of fertiliser for growth, and they are sensitive to drought. The aim of this  project is to study the beneficial effects of mycorrhizal fungi on the growth and development of Allium species and to determine whether it is possible to improve onions for mycorrhizal responsiveness by breeding. Variation among Allium species indicated that selection and thus breeding for high responsiveness to AMF is possible. Two years of experiments with genotypes of a population segregating for mycorrhiza responsiveness indicated that...

Rothår og fosforopptak i korn
Provedor de dados: 21

Lavere nivå av fosfor i jorda er rapportert på gårder med økologisk drift. Jordbruksvekster kan til en viss grad tilpasses lavere fosfornivå ved utvalg og avl for høgere fosforeffektivitet. Danske forsøk har vist at lange rothår kan være en faktor som øker fosforopptaket i korn. Funn fra et nylig avsluttet MSc-arbeid tyder på at det er forskjell i fosforopptaksevne mellom bygg- og hvetesorter, men at andre faktorer enn rothår har vel så i stor betydning for fosforopptaksevnen.

Use of DNA-based genetic markers in plant breeding
Provedor de dados: 21
Autores: Backes, Gunter.
Genetic markers have been used since the beginnings of plant breeding, but the concept of linkage and recently the availability of molecular markers have offered new and powerful tools that can help to perform the traditional tasks of selection or that can change the traditional breeding process. Markers can either be used in a descriptive manner to identify varieties, to study the ‘micro-evolution’ of composite crosses or variety mixtures or to analyse the breeding progress retrospectively in order to learn from the past. The operative use of markers in plant breeding is connected to the selection of parental lines and progeny lines. The possible implementation of these processes stretches from the introgression of specific chromosome fragments to...

Experimental data confirm the importance of appropriate selection environments for breeding maize adapted to organic farming systems
Provedor de dados: 21
Autores: Messmer, Monika; Burger, Henriette; Schmidt, Walter; Geiger, Hartwig H.
Organic farming systems, characterized by special attention to soil fertility, recycling techniques and low external inputs, gained increased significance in recent years. As a consequence, there is a growing demand for varieties adapted to organic and/or low input farming. In several studies modern varieties as well as landraces have been tested for their suitability for organic farming (OF), whereas special breeding programs aiming at genotypes optimized for this farming system are scarce. Comparing the testcross performance of unselected recombinant inbred lines derived from the widely used US hybrid B73 x Mo17 under conventional (CF) and organic farming systems, Lorenzana and Bernardo (2008) concluded that high yielding maize hybrids for OF can be...

Das Angebot an samenfesten Sorten des Chinakohl für den Erwerbsgartenbau ist praktisch gleich null. Um für den ökologischen Landbau Alternativen zur zunehmend kritischer betrachteten Hybridzüchtung zu erhalten, wurde während einer dreijährigen Projektlaufzeit versucht, fünf samenfeste Chinakohlsorten mittels Restsaatmethode und Prüfung von Einzelpflanzennachkommenschaften in Homogenität und Wertigkeit weiterzuentwickeln. Die Restsaatmethode, also das Zurückgreifen auf Saatgut, dessen Nachkommen bewertet wurden, erscheint bei Chinakohl als praktikabler Weg für die Züchtung, da eine Überwinterung von Elitepflanzen äußerst verlustreich ist.  Es zeigte sich bei den fünf Sorten eine sehr unterschiedliche Entwicklung in der Wertigkeit, doch konnte aufgezeigt...

Dairy cow breeding for organic farming
Provedor de dados: 21
Autores: Roderick, Stephen.
Organic farming requires that in the choice of breeds or strains, account must be taken of the capacity of animals to adapt to local conditions, their vitality, and their resistance to disease. In addition, breeds or strains of animals shall be selected to avoid specific diseases or health problems associated with some breeds or strains used in intensive production. This review considers the research into organic dairy cow breeds and breeding, it discusses the need for a specific organic approach to breeding and cross breeding and makes some clear recommendations for selection priorities.  This research review describes the outputs from a range of studies on dairy cattle breeding that have specific relevance to organic farming conditions.

Development of organic plant breeding and seed production will have a valuable impact on organic plant production. Breeding of plant material adapted for organic agriculture is crucial in order to cope with stresses such as climate change, weeds and seed borne diseases. Conventional varieties may not meet the specific needs of organic agriculture. The use of plant material adapted to conditions of organic agriculture will have a positive effect on the productivity and sustainability of organic crop production.

Pflanzenzüchtung für den ökologischen Landbau am Beispiel wichtiger ackerbaulicher Kulturen
Provedor de dados: 21
Autores: Vogt-Kaute, Werner.
Das Thema „Ökologische Pflanzenzüchtung“, vielfach auch mit einer „Pflanzenzüchtung für den Ökolandbau“ verwechselt oder in einen Topf geworfen, wurde bis vor wenigen Jahren und noch immer überwiegend von Vertretern der biologisch-dynamischen Wirtschaftsweise bearbeitet. Dabei wurden leider in verschiedenen Veröffentlichungen Themen, die nichts miteinander zu tun haben, inhaltlich vermischt, z. B. die Notwendigkeit der Öko-Vermehrung ab 2003 mit Öko-Züchtung, oder Gentechnik mit der Forderung nach einem Verbot von Hybridsorten. Dazu wird ein Begriffsklärung gegeben.   Wenn es staatliches Ziel ist, den Anteil des Ökolandbaus auszuweiten, dann muss der Staat auch entsprechend Gelder für Forschung bereitstellen, auch für den Bereich der Pflanzenzüchtung. Dies...

Horntragende Rinderzucht sichern. Eine Status-Quo-Analyse der Zucht hornloser Milchrinder
Provedor de dados: 21
Autores: Scheper, Carsten.
Die zunehmende Zucht auf genetische Hornlosigkeit führt in einigen Rassen dazu, dass es bald zu einer hornlosen Zuchtbullenpopulation kommt, sodass keine Bullen oder Sperma mehr vorhanden sind, die die genetische Ressource Horn weitervererben. Die trifft vor allem auf die Rassen Fleckvieh und Holstein (Schwarz- sowie Rotbunt) zu. In kleineren Rassen ist die genetische Hornlosigkeit noch nicht so weit voran geschritten, Tendenzen aber erkennbar.

Breeding Goals for Organic Dairy Farming in Denmark Based on the Principles of Organic Agriculture
Provedor de dados: 21
Autores: Slagboom, Margot; Wallenbeck, Anna; Rydhmer, Lotta; Thomasen, Jørn Rind; Kargo, Morten.
Organic dairy farming (ODF) is different from conventional dairy farming in management practices, but so far the same breeding goal (BG) is used, based on the same economic models (EM). However, ODF is based on the principles of organic agriculture defined by the IFOAM, which are not easily interpreted in economic terms and it may be questionable to use a BG for ODF based on EM. In this study we set up three BGs for ODF in Denmark, one based on the principles of organic agriculture, one focusing on roughage consumption and feed efficiency, and one focusing on disease resistance. A questionnaire and desired gains index were used to set up the BGs. Correlations between these BGs and BGs based on EM were low. Which BG would be best suitable to use for ODF in...

Den faglige baggrund:Økohøns kræver eget avlsarbejde
Provedor de dados: 21
Autores: Sørensen, Poul.
Økologisk ægproduktion begyndte for ca. 6 år siden, og har siden da været gennem ganske mange problemer. Dødeligheden over de sidste 6 år har været 3-7% højere i den økologiske produktion end hos konventionelt fritgående høner. Selv om de to produktionssystemer ligner hinanden, er der forskelle, der kan være med til at forklare den højere dødelighed:  1. Det er ikke tilladt at næbtrimme økologiske høner  2. I den økologiske produktion er der store restriktioner på forebyggende sygdomsbehandling og 3 gange længere tilbageholdelses tid efter sygdom   3. Det er vanskeligere at sammensætte en balanceret fodring i den økologiske produktion.       Det er almindelig accepteret, at de høneafstamninger, der idag er på markedet beregnet til høj ægproduktion i...

Plant traits affecting thrips resistance in cabbage
Provedor de dados: 21
Autores: Voorrips, Roeland E.; Steenhuis-Broers, Greet; Tiemens-Hulscher, Marjolein; Lammerts van Bueren, Edith T.
The development of thrips populations and thrips damage in 15 cabbage varieties was monitored in two years of field experiments in the Netherlands..  A number of morphological and physiological plant traits were also measured. The most important factors leading to a low level of thrips damage were late development of a compact head, a low Brix value and a high amount of leaf wax. Two open-pollinated cabbage varieties with low and high susceptibility to thrips damage were crossed in both reciprocal combinations. The resulting F1 populations were intermediate for susceptibility to thrips damage.

Der ökologische Gesamtzuchtwert (ÖZW) als wichtiges Hilfsmittel für züchterische Entscheidungen im ökologischen Milchviehbetrieb
Provedor de dados: 21
Autores: Krogmeier, Dieter; Gerber, Antonia.
Der ÖZW für Bullen für die Rassen Braunvieh, Fleckvieh und Gelbvieh ist seit vielen Jahren in der Zuchtpraxis etabliert und er ist für ökologische aber auch für interessierte konventionelle Betriebe ein wichtiges Hilfsmittel bei der Bullenauswahl. Entsprechend dem ÖZW für Bullen wurde ein ÖZW für Kühe entwickelt, der seit Ende 2008 für die ökologischen Milchviehbetriebe gerechnet wird. In Kombination ist der ÖZW für Bullen und Kühe ein wichtiges Hilfsmittel für züchterische Entscheidungen im ökologischen Milchviehbetrieb und er soll in Zukunft dazu beitragen, dass die Bedürfnisse der ökologischen Milchviehbetriebe stärker in den aktuellen Zuchtprogrammen berücksichtigt werden.

Breeding high quality apples combined with excellent agronomic features promotes  sustainable production systems. This approach includes durable genetic disease  resistance against scab (Venturia inaequalis), powdery mildew (Podosphaera  leucotricha) and fire blight (Erwinia amylovora). Glasshouse screening of advanced  selections and traditional cultivars with a shoot inoculation test for fire blight resistance  highlighted considerable differences. We report on approaches for breeding new high  quality scab and mildew resistant and fire blight tolerant varieties including markerassisted  selection (MAS) and on promising advanced selections.

Evaluation of Nordic heritage varieties and NILs for resistance to common bunt (Tilletia caries syn. T.tritici)
Provedor de dados: 21
Autores: Borgen, Anders; Svensson, Jan; Wiik, Lars.
A number og wheat varieties from NordGen and Allkorn were tested fro susceptibility to common bunt. Most were susceptible to common bunt which is in line with other screening experiments of randomly selected varieties. However, a few lines not previously known to be resistant were shown to have different resistance genes. None of them however were resistant to all the virulence races tested. NILs developed by MacKey were evaluated and there seem to be a potential for using some of them as differential lines for resistance gene Bt1, Bt5, and Bt9. Purification based on resistant head rows may also develop NILs with resistance to Bt6 and Bt10 and possible also Bt7 from NGB16160. A crossing program of the remaining Bt-genes was started in 2016. The NILs may be...

Carbon isotope discrimination and water use efficiency relationships of alfalfa genotypes under irrigated and rain-fed organic farming
Provedor de dados: 21
Autores: Moghaddam, Ali; Raza, Amir; Johann, Vollmann; M.Reza, Ardakani; Wolfgang, Wanek; Gabriela, Gollner; Juergen K., Friedel.
Carbon isotope discrimination (∆) has been proposed as a method for evaluating water use efficiency (WUE) in C3 plants and as a precise technique for screening plants with higher tolerance under water deficit conditions. In this research, 18 alfalfa genotypes from different geographical origins were evaluated under irrigated and rain-fed conditions in organically manged fields in Austria. Significant differences were found amongst harvests for ∆-shoot under both conditions while genotype by harvest interaction was only significant under irrigated condition. Drought stress under rain-fed condition reduced the overall mean of water use efficiency and carbon isotope discrimination responses(up to 34%), but the ratios of reduction differed for characters and...

Autores: Schubbert, Antje; Dodenhoff, J.; Obermaier, Sabine.
In this study the impact of defensive behavior on reproductive performance was investigated in 75 litters of German Landrace sows. Defensive behavior was assessed  piglets and was categorized into three different grades (1 to 3). Performance data for a number of reproductive traits were collected from birth to weaning. The effect of  defensive behavior on these traits was analyzed with the SAS procedure GLM. Even though for most traits considerable differences between categories were observed, the  effects were statistically not significant. This could be due to the relatively small number of observations available for this study.

Wachstumsverlauf und Ertrag verschiedener Smallanthus sonchifolius Genotypen
Provedor de dados: 21
Autores: Kamp, L; Mast, Benjamin; Claupein, Wilhelm; Graeff-Hönninger, Simone.
The tuberous root plant yacon (Smallanthus sonchifolius) is native to the Andean region. It produces eatable roots, which contain roughly 70 % carbohydrates in dry  matter. Nearly all of them are fructooligosaccharides (FOS), which are not digested by the human intestinal tract and do not cause an increase of the blood glucose level  (Lachman et al. 2003). In order to identify the potential of yacon for temperate climates two yacon genotypes were investigated in a field trial located in South-West Germany.  In this field trial the focus was set on tuber yield and plant development. The results of 2015 showed significant differences in tuber yield of a red (3.3 kg per plant) and a  brown genotype (2.5 kg per plant). A revers picture has been found for the...

The organic seed regulations framework in Europe – current status and recommendations for future development
Provedor de dados: 21
Autores: Döring, Thomas F.; Bocci, Riccardo; Hitchings, Roger; Howlett, S. A.; Lammerts van Bueren, E.T.; Pautasso, Marco; Raaijmakers, M; Rey, F; Stubsgaard, Anke; Weinhappel, M.; Wilbois, Klaus-Peter; Winkler, Louisa; Wolfe, M S.
Organic agriculture regulations, in particular European regulation EC 889/2008, prescribe the use of organically produced seed. For many cultivated plants, however, organic seed is often not available. This is mainly because investment in organic plant breeding and seed production has been low in the past. To bridge the gap between organic seed supply and demand, national and European regulations define certain circumstances under which organic producers are permitted to use non-organically produced seed. While the organic sector currently depends on these concessions, they also threaten to impede a further increase in the demand for organic seed, thereby potentially restraining present and future investment in organic seed production and plant breeding....

Mapping of common bunt resistance gene Bt9 in wheat
Provedor de dados: 21
Autores: Steffan, Philipp; Torp, Anna-Maria; Borgen, Anders; Backes, Gunter.
Increasing organic wheat production in Denmark, and in other wheat-producing areas, in conjunction with legal requirements for organic seed production, may potentially lead to a rise in common bunt occurrence. As systemic pesticides are not used in organic farming, organic wheat production systems may benefit from genetic resistances. However, little is known about the underlying genetic mechanisms and locations of the resistance factors for common bunt resistance in wheat. A double haploid (DH) population segregating for common bunt resistance was used to identify the chromosomal location of common bunt resistance gene Bt9. DH lines were phenotyped in three environments and genotyped with DArTseq and SSR markers. The total length of the resulting linkage...

Plant Breeding Techniques
Provedor de dados: 21
Autores: Wyss, E.; Lammerts van Bueren, E.T.; Hulscher, M.; Haring, M.
Seeds form the basis for agricultural production, but most organic growers know little about how their seedstocks have been produced. Within the organic movement the discussion on the compatibility of plant breeding techniques has been accelerated by the public discussion on genetic engineering. This decision-making is important to develop a framework for organic plant breeding and facilitate investment by breeding companies. This dossier explains all standard techniques used in modern plant breeding and why they have been developed. The consequences of not allowing certain techniques for organic plant breeding are outlined, along with suggestions for alternative techniques that could be adopted.

What socially motivates farmers to grow organic cotton in central India?
Provedor de dados: 21
Autores: Riar, Amritbir; Mandloi, Lokendra S.; Poswal, Randhir S.; Messmer, Monika; Bhullar, Gurbir S.
India is the largest producer of ‘organic cotton’, as it contributes about three quarters (74%) to the global organic cotton production. The Nimar valley of Madhya Pradesh in central India is important region for organic cotton production. In general, cotton yields are low and variable in the Nimar valley and often do not reach the attainable levels on several farms of the region. With a steeply increasing demand for organic fibre, it is important to safeguard and increase the production of organic cotton in a sustainable manner. The precise understanding of social and biophysical motivations of different farmers for following their respective farming practices is of high importance for sustainable future of organic cotton in central India. The study of...

Bunt is one of the most devastating diseases of wheat, in Europe and  Northern  America  mainly  caused  by Tilletia  caries and T.controversa, in  the  warmer  climates  of  the  Near  East  by T.foetida. The generally obligate biotrophic pathogen is trans-mitted by contaminated seeds or can ersist in the soil. Infection occurs at the very first moments after germination of the grain. Once penetrated into the plant, the fungus grows endophytically, remaining undetected until early maturity stages when grains are replaced by spores. Besides yield losses, the malodorant spores contaminate the grains impairing their use as seeds or as food, thereby leading to serious economic losses. Usually the disease is controlled by the use of seed dressings and the use...

Genetic analysis of predicted fatty acid profiles of milk from Danish Holstein and Danish Jersey cattle populations
Provedor de dados: 21
Autores: Hein, Lisa; Sørensen, Lars Peter; Kargo, Morten; Buitenhuis, Albert Johannes.
The objective of this study was to assess the genetic variability of the detailed fatty acid (FA) profiles of Danish Holstein (DH) and Danish Jersey (DJ) cattle populations. We estimated genetic parameters for 11 FA or groups of FA in milk samples from the Danish milk control system between May 2015 and October 2016. Concentrations of different FA and FA groups in milk samples were measured by mid-infrared spectroscopy. Data used for parameter estimation were from 132,732 first-parity DH cows and 21,966 first-parity DJ cows. We found the highest heritabilities for test day measurements in both populations for short-chain FA (DH = 0.16; DJ = 0.16) and C16:0 (DH = 0.14; DJ = 0.16). In DH, the highest heritabilities were also found for saturated FA and...

Divergent selection on feather pecking behavior in laying hens has caused differences between lines in egg production, egg quality and feed efficiency
Provedor de dados: 21
Autores: Su, Guosheng; Kjaer, Jørgen B.; Sørensen, Poul.
The correlated changes in egg production, egg quality, and feed efficiency due to selection for or against feather pecking (FP) were investigated by analyzing the data from an experiment including two divergent selection lines and a control line. The experiment was conducted with hens at the age of 42 to 46 weeks (hatch 1) and 39 to 43 weeks (hatch 2) in the fifth generation of selection. Number of FP bouts per hour in low FP line (LP) was significantly lower than that in high FP line (HP) (0.38 vs. 2.01), and total plumage score in line LP was significantly better than that in line HP (16.9 vs. 11.6). During the four weeks, egg number and egg mass in line LP were significantly higher than those in line HP (24.4 vs. 18.3, and 1223 g vs. 1132 g).  On the...

Differences in Yield Parameters of Emmer in Comparison with Old and New Varieties of Bread Wheat
Provedor de dados: 21
Autores: Petr, Konvalina; Ivana, Capouchová; Zdeněk, Stehno; Jan, Moudry.
Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different localities in the Czech Republic. Results of the research were compared to characteristics of four old and two top  modern bread wheat (Triticum aestivum L.) cultivars. The emmer wheat varieties were resistant to usual wheat diseases. They formed their yield by a quantity of productive tillers (2.5), whereas the varieties of bread wheat had less productive tillers...

Association Mapping for Common Bunt Resistance in Wheat
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Backes, Gunter; Rasmussen, Søren K.
Common bunt, caused by Tilletia caries and T. foetida, is a fungal disease of wheat world wide. Infection, occurring via seed borne teliospores, is generally controlled by the application of seed treatments prior to sowing. Farming systems like organic agriculture with a very limited range of organic seed treatments available rely heavily on common bunt resistance genes within wheat. In the framework of the BIOBREED project an association study in winter wheat was conducted, aiming at the identification of genetic loci linked to resistance towards common bunt in wheat.  152 European wheat cultivars were phenotyped for their resistance reaction for the two consecutive years 2011/12 at Agrologica research station at Mariager. Infection was scored as percent...

Transmission of Xanthomonas campestris pv. campestris by the fly Calliphora vomitoria to blooming cauliflower plants (Brassica oleracea)
Provedor de dados: 21
Autores: van der Wolf, J. M.; van der Zouwen, P.S.; Garbeva, P.; Köhl, J.
Xanthomonas campestris pv. campestris (Xcc) is a seed borne pathogen that causes black rot, a destructive disease of cabbage. Exclusion of infec-tions is the most effective way to control black rot in organic seed production. Within this frame, the role of insects in transmission of Xcc to seed was deter-mined. It was found that Xcc survived for three days on flies (Calliphora vomitoria), used for pollination of cabbage plants in tunnels and greenhouses. In tunnel experiments, both the use of Xcc-contaminated flies and brush inoculation of flowers with Xcc resulted in internal seed infections. The implications for seed production are discussed.

Fatty acid profile of ghee derived from two genotypes (cattle–yak vs. yak) grazing different alpine Himalayan pasture sites
Provedor de dados: 21
Autores: Marquardt, Svenja; Barsila, Shanker R.; Amelchanka, Sergej L.; Devkota, N.R.; Kreuzer, Michael; Leiber, Florian.
The fatty acid (FA) profile of ghee produced from milk of cattle–yak hybrids grazing five mountain pasture sites along a high-alpine transhumance route in Nepal was analysed. Pastures differed in altitude above sea level(2600–4500 m), time period of being grazed and phytochemical composition of the swards. Additionally, a comparison of ghee from purebred yak and hybrid was performed, with samples produced at two of the sites. Pasture site had a strong effect on almost all FAs. Proportions of oleic, linoleic and a-linolenic acid in ghee were smallest on the highest pasture at 4500 m where the largest condensed tannin concentrations in the forages were found. No systematic site effects were found for c9,t11 conjugated linoleic acid and total polyunsaturated...

Organic dairy breeding lines? – Possibilities and Requirements
Provedor de dados: 21
Autores: Kargo, Morten; Thomasen, Jørn Rind; Wallenbeck, Anna; Hjortø, Line; Slagboom, Margot.
Genomic breeding schemes with large cow reference populations will give room for more line division within dairy cattle breeding and therefore also for organic breeding lines. The reason is that different economic values between organic and conventional production systems are expected in the future and the existence of genotype by environment interaction will presumably be even more recognized. Therefore, correlations between organic and conventional breeding goals are expected to be significantly lower than one. This in combination with increased future “break even” correlations opens up for specific organic breeding lines.

Die in der ökologischen Geflügelhaltung genutzten genetischen Herkünfte eignen sich aus verschiedenen Gründen in unterschiedlichen Maß für diese Verfahren. Die Bewertung der Eignung reduziert sich bisher im Wesentlichen auf Aspekte der Leistung (u.a. Eizahl, Eigewicht, Futterverwertung) sowie in gewissem Maße des Verhaltens (u.a. Kannibalismus). Aspekte der Tiergesundheit werden  häufig auf Mortatiltätsraten reduziert, so dass u.a. subklinisch verlaufende Erkrankungen unberücksichtigt bleiben. In ökologischen Haltungsverfahren für Legehennen zählen die Parasitosen, insbesondere die Helminthosen, vor allem verursacht durch Ascaridia galli, Capillaria-Arten und Heterakis gallinarum, zu den bedeutendsten Erkrankungen (KAUFMANN und GAULY, 2009).

Crop traits relevant for selecting potato genotypes adapted to low nitrogen availability
Provedor de dados: 21
Autores: Tiemens-Hulscher, Marjolein; Lammerts van Bueren, E.T.; Struik, Paul.
Canopy cover development was measured for 6 to 18 different potato varieties, under 3 different nitrogen regimes. This canopy cover development can be expressed in several paramaters. Of these parameters, the 'Area Under Cover Progress Curve' and the 'percentage of maximal ground cover' show the highest correlation with the final yield in low-nitogen conditions.

Selektion av genotyper med ett högt kväveutnyttjande, hög ogräskonkurrens och hög allelopati i förädlingsmaterial av vete och korn för ekologisk odling
Provedor de dados: 21
Målsättningen är att fortsätta en påbörjad förädling av korn och vetesorter för ekologisk produktion. Hydrokulturtekniker har tidigare använts för screening av genotyper med en kraftigare tillväxt på våren av skott och rot. Dessa egenskaper har påvisats vara positiva både för kväveupptagningen och ogräskonkurrensen. Genom att utnyttja hydrokulturer är det möjligt att reducera antalet linjer som testas i ekologiska fältförsök.                                 De tidigare genomförda fältförsöken visar även att allelopati är en viktig egenskap både i korn och vete. Speciellt i vete bör en förädling på ökad allelopati (dvs. förmåga att hålla tillbaka ogräsen genom att utsöndra olika kemiska substanser) vara effektiv då aktiviteten endast är hälften av den hos...

Identifying resistance genes in wheat against common bunt (Tilletia caries) by use of virulence pattern of the pathogen
Provedor de dados: 21
Autores: Borgen, Anders; Backes, G.; Müller, Karl-Josef; Gallehr, Andrea; Scherrer, Bettina; Ytting, Nanna Karkov; Spieß, Hartmut.
455 wheat varieties and breeding lines were grown in the field,contaminated with 7 to 11 different races of common bunt. Based on the reaction of the lines to the different virulence races, it was possible to group the lines by differential varieties with known resistance genes, indicating that they may have one or two of the resistance genes Bt1, Bt2, Bt5, Bt7, Bt13, BtZ or Quebon-resistance. Based hereof, genetic markers will be developed using a genome-wide association study (GWAS).

Breeding for improved responsiveness to arbuscular mycorrhizal fungi in onion
Provedor de dados: 21
Autores: Galvan, Guillermo A.; Burger, Karin; Kuyper, Thom W.; Kik, Chris; Scholten, Olga E.
Arbuscular mycorrhizal fungi (AMF) play an important role in the uptake of nutrients and water from soil. Onions, Allium cepa L., are plants with a shallow root system. As a result, onion plants need a lot of fertiziler for their growth. Furthermore, onion plants are sensitive to drought. The aim of the current research project is to study the beneficial effect of mycorrhizal fungi on the growth and development of Allium species and to determine whether it is possible to improve onions for mycorrhizal responsiveness by means of breeding. Variation among Allium species and segregation observed in a interspecific tri-hybrid population indicate that selection and thus breeding for high responsiveness to AMF is possible.

Der Kultursaat e.V. setzt sich für die Verbesserung des Sortenspektrums für den Erwerbsgemüsebau ein. Aus Arbeiten in der Saatgutgärtnerei Schönhagen und am Dottenfelderhof war bekannt, dass Geschmack und Mundgefühl von Pastinaken innerhalb und zwischen Sorten sehr unterschiedlich sein können.   Pastinaken sind, obwohl in Europa heimisch, wenig genutzt.   Die geringe züchterische Bearbeitung ist eine Ursache dafür.   Durch Verbesserung von Geschmack und Textur mittels Auslese stehen zwei biodynamische Sorten für alle Verwendungszwecke zur Verfügung.

In der Milchrinderzucht erfolgt der gezielte Einsatz von Zuchttieren üblicherweise durch die künstliche Besamung. Der Einsatz von Deckbullen nimmt jedoch zu. Hierzu wurde eine Befragung von Landwirten, die einen Deckbullen halten, in Oberbayern durchgeführt. Obwohl es in der Praxis verschiedene Meinungen zu der Haltung und dem Umgang mit Natursprungbullen gibt, würden sich die befragten Betriebsleiter erneut dafür entscheiden.  Als Vorteil des Natursprungs wird von den untersuchten Betrieben vor allem die verbesserte Fruchtbarkeit der Kühe und der reduzierte Arbeitsaufwand gesehen. Demgegenüber sind als Nachteile das Risiko unerwünschter Zuchterfolge und der Platzbedarf für den Bullen zu sehen.   Die Zuchtbullen kommen überwiegend aus der eigenen Nachzucht...

Participatory plant breeding: a way to arrive at better-adapted onion varieties
Provedor de dados: 21
Autores: Tiemens-Hulscher, M.; Lammerts van Bueren, E. T.; Osman, A.; Jeuken, J.; Groenen, R.; de Heer, R.
The search for varieties that are better adapted to organic farming is a current topic in the organic sector. Breeding programmes specific for organic agriculture should solve this problem. Collaborating with organic farmers in such programmes, particularly in the selection process, can potentially result in varieties better adapted to their needs. Here, we assume that organic farmers' perceptive of plant health is broader than that of conventional breeders. Two organic onion farmers and one conventional onion breeder were monitored in their selection activities in 2004 and 2005 in order to verify whether and in which way this broader view on plant health contributes to improvement of organic varieties.  They made selections by positive mass selection in...

Improving "low input" dairy cattle production systems
Provedor de dados: 21
Autores: Biscarini, Filippo.
Thanks to developments in DNA sequencing technology, in recent years a growing amount of information on the genetic make-up of livestock animals have become available. This information, typically in the form of panels of single nucleotide polymorphisms (SNPs), has been used in farm animals populations – usually specific breeds - to map QTLs and, more recently, to estimate genome-wide breeding values (GEBVs) to be used in the so-called genomic selection schemes. Not much attention has been paid to differences between animals farmed in different environments, such as intensive or rural production systems. Research and applications have so far focused on high input farming, due mainly to the larger available populations and the greater commercial interest....

Simulating consequences of choosing a breeding goal for organic dairy production
Provedor de dados: 21
Autores: Slagboom, Margot; Wallenbeck, Anna; Hjortø, Line; Sørensen, Anders Christian; Thomasen, Jørn Rind; Kargo, Morten.
Six different breeding goal (BG) scenarios were developed and simulated for organic and conventional dairy production, to study the effect on genetic change for specific traits. The first two BGs (BG1 and BG2) were based on economic weights from SimHerd simulations for a conventional and an organic dairy system in Denmark. The third BG (BG3) was based on weights derived from a farmer preference survey for organic farmers. The fourth BG (BG4) was based on the four organic principles defined by the IFOAM, and on the results of a questionnaire that was sent out to farmers, researchers and experts in the area of organic dairy husbandry. The fifth and sixth BGs (BG5 and BG6) were based on BG4, but altered to put more emphasis on roughage consumption and disease...

The parents will be selected partly on past knowledge of successful performance in terms of yield, quality and disease resistance and partly on the basis of molecular ancestry to try to ensure as wide range of diversity as possible. Following parental inter-crossing in all possible combinations, progeny population samples will be exposed to a range of widely different agricultural environments and systems through several seasons of, largely, natural selection. Performance of the population samples will be compared at different stages against both the parents grown as pure stands and as physical mixtures.   Our objective...

Selection and characterization of ‘low input’ farm groups in 3 macro-climatic regions in Europe for inclusion in a “farmer participatory” performance recording network (FP-PRN) and performance recording of currently used layer genotypes
Provedor de dados: 21
Autores: Leenstra, Ferry; Maurer, Veronika; Bestman, Monique; Zeltner, Esther; van Niekerk, Thea; Galea, Fabien; Reuvekamp, Berry.
In poultry, breeding is carried out by a very limited number of international operating breeding companies. For laying hens two companies dominate the market. Laying hens are in general 4-way crosses. Since 1960 the majority of commercial layers are bred and housed in cages. Non-cage housing started to appear again from 1980 onwards and increases slowly in importance, at first in Europe, but recently also in North America. It is questionable if birds bred to perform in cages are also suited for free range housing. In this project we examine the performance of current genotypes in free range systems (organic and conventional), and if and how an improved genotype for free range housing can be developed.

Autores: Howlett, Sally; Winkler, Louisa; Döring, Thomas F.; Pearce, Helen; Negri, Valeria; Torricelli, Renzo; Wolfe, Martin.
Field trials were conducted for three years on an organic farm in England to assess the performance and yield variability of two synthetic sprouting broccoli populations with 4 or 8 parents respectively, along with the original landrace mother plants and a commercial F1 hybrid variety as control (Santée). In terms of total yield, Santée outperformed the other entries, but for some other traits, e.g. heading time and number of sprouts, Santée was comparable with the mean of one or more of the genetically diverse entries. Analysis of yield variability over time showed mixed results. With regard to total yield and total sprout number, variability was higher in the F1 hybrid than in the genetically diverse populations, but for other parameters such as average...

A reduced extent of variety trials in organic agriculture makes a regional recommenda-tion more difficult. The Hohenheim-Gülzower method was developed for the evalua-tion of the conventional national variety trials in the states of the Federal Republic. This method should optimize the interpretation of test results in organic agriculture, too. Problems are shown by example of variety trials with grain peas. The new method enabled the representation of results by regionalization and weighed inclusion of adjacent regions.

In the period from 1992 to 1998 the fat and protein yield of both flocks could be increased. A specific breeding strategy had an important contribution to the increase but the environmental impacts on animal productivity is enormous (e.g. the very wet summer season 1994). A wrong decision in breeding bucks (dairy sheep in 1992-1994) had an negative effect on the productivity.

Prediction of grain yield of spring barley varieties by disease and growth characteristics from VCU testing
Provedor de dados: 21
Autores: Oestergaard, Hanne; Kristensen, Kristian; Jensen, Jakob W.
Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied greatly within and between environments (years and sites) and systems. Furthermore, the variation among varieties was substantial and differed among different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model was found for predicting the observed grain yield each year from these characteristics in the previous year. In this model, the...

Vergleich lokaler und kommerzieller Milchviehrassen im Biolandbau
Provedor de dados: 21
Autores: Bieber, Anna; Spengler Neff, Anet.
Die Biolandbau-Richtlinien empfehlen die Verwendung lokal angepasster Nutztierrassen. Es existieren bisher jedoch kaum Studien zur Eignung lokaler Milchviehrassen unter den Bedingungen des Biolandbaus.  Lokal angepasste Milchviehrassen könnten besser an die Bedingungen des Biolandbaus angepasst sein als kommerzielle Rassen, da ihre Leistung auf die lokale Futtergrundlage und graslandbasierte Fütterungssysteme abgestimmt ist.   Auf dem Poster werden die Ergebnisse des Vergleichs von Braunviehkühen mit einem Brown Swiss Blutanteil von mind. 60% als kommerzielle Rasse mit den zwei lokalen Rassen Original Braunvieh und Grauvieh auf Schweizer Biobetrieben gezeigt.

Estimation of genetic parameters for individual udder quarter milk content traits in Brown Swiss cattle
Provedor de dados: 21
Autores: Kramer, M.; Erbe, M.; Bapst, B.; Bieber, A.; Simianer, H.
The aim of this study was to estimate genetic parameters and accuracies of breeding values for milk content traits of individual udder quarters in Brown Swiss cattle. Data of 1,799 phenotyped cows from 40 Swiss dairy herds were analyzed, taking the complete pedigree into account. Fat, protein, lactose, and urea contents, somatic cell score (SCS), and information about hyperkeratosis were available for each udder quarter. The milk of rear udder quarters was found to have significantly higher lactose content and significantly lower fat content than milk of the front udder quarters. The same trend found for fat content was observed for protein content, whereas no differences between the udder quarters were observed for urea content, SCS, or hyperkeratosis....

Züchterische Weiterentwicklung samenfester Brokkolisorten  für den Ökolandbau hinsichtlich agronomischer  wie sensorischer Merkmale
Provedor de dados: 21
Autores: Fleck, Michael; Wolf, Stefanie; Claupein, Wilhelm.
Starting from identified breeding populations of broccoli, new open-pollinated broccoli varieties (OP varieties) are to be developed by means of two intensive individual selection steps with progeny testing in an on-farm approach. These new varieties are to meet the demands of organic vegetable production. To achieve this, agronomic characteristics such as yield stability, uniformity, short harvesting period, sufficient firmness of the head are sought after, coupled with good sensory characteristics and high amounts of bioactive substances beneficial to health and excellent taste.

Autores: Bapst, B.; Bieber, A.; Haas, E.
A survey on 1000 organic dairy cattle farms was done to obtain information on the state of breeding affairs in Switzerland. The response of 60% of returned questionnaires was very high. Milk performance data were average for organic as well as for traditionally managed farms. The farmers weighted functional traits to be very important in breeding.  The bulls used on organic farms were compared with the bulls used on traditional farms. A total of 25067 organic and 28003 traditional matings of Swiss Braunvieh was analysed. The comparison of breeding values of the sires showed that in the scope of selection strategies the functional traits were not as important. It is concluded that organic farmers persecute an organic breeding strategy but in the particular...

Do endangered sheep breeds have an advantage in organic farming?
Provedor de dados: 21
Autores: Rahmann, Gerold.
Endangered breeds are not compulsory for organic farming, but adapted and local breeds are considered suitable for Organic Farming. In the year 2001, 240 ewes of six different breeds were introduced on the experimental farm of the Institute of Organic Farming in Trenthorst. Two were high yielding breeds, four older endangered German breeds. The whole herd was kept in one herd in a low input – low output system, comparable to agri-environmental schemes. The scientific programme was to follow the herd’s development in terms of health status, growth rate and product qualities.   After three lambing seasons, no real advantages could be found for the old breeds. Nevertheless, high yielding and old breeds did not show big differences in production and health...

The quality of seed is the basis of successful organic plant production. Since seed treatment with synthetic chemicals is not allowed in organic farming, it is important to find alternative methods for seed treatment instead of that process. The goal of our research was to find methods that retain good quality of organic seed and assure high field emergence. The experiment consisted of two parts. In the first part, the effects of the chosen materials on germination green pea (Pisum sativum L.) seeds was measured. In the second part, the effect of the chosen materials on the seed-borne fungi Ascochyta sp., and Fusarium moniliforme on corn seed was observed. The chosen methods were warm water, Biokál, Alginit and Vetozán -permitted fertilisers and...

Erhaltung und Generierung genetischer Ressourcen durch die Entwicklung moderner Landrassen unserer Kulturpflanzen: Wozu wir die Ko-Evolution im Feld brauchen
Provedor de dados: 21
Autores: Finckh, Maria R.
Over the past 100 years, the biodiversity within varieties and species of field crops in agriculture has been reduced drastically through plant breeding approaches favouring genetic uniformity for all traits. This has practically eliminated all co-evolutionary proc-esses between hosts and their pests and pathogens. It also does not allow for dy-namic adaptation of plant populations to changing environment e.g. climatic change. Breeders and pathologists have all along pointed out the danger of this approach. Alternative approaches to the pure line breeding have been developed by using com-posite crosses, top crosses and population breeding. These have also been termed “evolutionary breeding”. The need for the reintroduction of diversity within our varieties...

Udsædsbårne sygdomme kan opdeles efter hvordan de smitter kornet. Nogle sygdomme (fx byg bladplet og stribesyge) inficerer kernerne, således at svampen er til stede inde i selve kernen allerede ved høst. Andre sygdomme kontaminerer såsæden med sklerotier (fx meldrøjer, Borgen 2005a) eller sporer (fx stinkbrand eller rugens stængelbrand, Borgen 2005b).    Sygdommenes forskellige tilstedeværelse i såsæden har betydning for, hvilke renseprocesser, der kan anvendes til at reducere deres forekomst.

Common bunt resistant wheat composite cross populations
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Backes, Gunter; Rasmussen, Søren K.
Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time.  BIOBREED is a project started in Denmark in 2011 to meet these challenges for wheat population breeding. The project is focusing on the development...

The aims of the present study were i) to analyse the genetic structure of the local black and white cattle breed (DSN), and ii) to analyse genotype by environment interactions based on defined herd parameter groups (geographic, environmental, phenotypic descriptors). The study considered 3688 DSN and 3599 HF cows from 46 herds keeping both breeds. Farms mostly reflected pasture based low input production systems. A multiple trait approach, i.e. defining same traits in different clusters as two different traits, was applied to prove genotype by environment interactions based on genetic correlation estimates. Genetic correlations between low heritability functional traits were lower than for production traits. Especially for functional traits such as somatic...

‘Low input’ pig production systems are usually characterised by smaller herd size, more space per animal, lower capital investment, often outdoor management, provision of bedding, greater labour requirement and focus on animal welfare. Examples of ‘low input’ pig production systems are “Iberico” in Spain, “Neuland” pigs in Germany, “Scharrelvarkens” in The Netherlands, “Natura Farm” in Switzerland, “Label Rouge” in France and “Freedom Food” in United Kingdom.  Organic pig production systems have similar characteristics to those described for ‘low input systems’ above. However, organic farming standards prescribe e.g. low stocking densities, access to outdoor runs, restrict the level of ‘bought in, non-organic’ feeds etc, which usually results in higher...

Different traits have been defined to describe the performance of dairy animals during their lifetime: productive lifetime, lifetime production, life efficiency and contribution trouble-free cows that reach the performance optimum of lactations. This continuous performance should be on basis of good roughage feed efficiency. Within the present total merit indices it is not possible to determine which cow fulfils these demands on longevity, health, performance and cost reduction. Further research is necessary to investigate the suitability of this trait for breeding value estimation or if the calculation of an index may be more useful.

The evaluation and use of the vast diversity contained in plant genetic resources (PGR) is a main challenge for today’s plant breeding. The use of molecular markers has hugely increased the knowledge about genetic diversity and great hopes are raised about the potential of marker assisted selection [MAS; sometimes also termed SMART breeding (Selection with Markers and Advanced Reproductive Technologies)] to help increasing the use of PGR and maintaining crop genetic diversity. Another approach growing attention has been paid to over the past two decades and which also aims to increase variation in crops is evolutionary and participatory breeding (EPB).

A Collaborative Breeding Strategy for Organic Potatoes in the Netherlands
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.
The ability of the organic farmer’s agronomic toolbox to reduce the susceptibility of a potato crop to late blight is limited, certainly under the Dutch climatic conditions. Conventional breeding programs do not generate either a sufficient number nor appropriate types of resistant varieties for organic systems; and a separate breeding program for the limited area of organic potato production is simply not viable. Therefore, all concerned forces have joined together in an umbrella program called Bioimpuls for organic potato improvement.

Aufbau einer Sammlung (Erhaltungszuchtbank) für samenfeste Gemüsesorten als Basis für ökologische On-farm-Züchtung
Provedor de dados: 21
Autores: Fleck, Michael; Nagel-Heinze, Christine.
Die Verfügbarkeit von ökologisch vermehrtem Saatgut bzw. der Sortenauswahl wird insbesondere bei Gemüse als unzureichend eingestuft. Die verwendeten Sorten sind bei vielen Gemüsekulturen zum überwiegenden Teil Hybriden, die für eine on-farm-Erhaltung ungeeignet sind oder im Falle von aus Zellfusion stammenden CMS-Hybriden nicht mehr fertil und auf Betrieben der Ökolandbauverbände per Richtlinie verboten sind. Diese beiden Aspekte der Saatgutfrage waren maßgebend für die Realisierung dieses Projektes.  Mit dem Ziel, die Eignung der Sorten für den ökologischen Gemüsebau zu prüfen, wurden 164 Saatgutmuster noch verfügbarer Populationssorten der Kulturen Kohlrabi (15), Möhren (86) und Porree (63) am europäischen Saatgutmarkt erworben und als Ausgangsmaterial...

Die Sonnenblume – eine Eiweißpflanze für den Ökologischen Landbau?
Provedor de dados: 21
Autores: Hahn, Volker.
Even though sunflower is primarily considered an oilseed crop, sunflower meal or cake is interesting for animal food, especially for organic farming, where the supply of protein is complicated. The quality of the oil cake is determined by its protein content. A breeding goal for the use of sunflower meal as a protein source is thus to increase the protein content of sunflower seeds without decreasing the oil content.

Dependence  of organic vegetable production on conventional seeds: are we ready for emancipation?
Provedor de dados: 21
Autores: Micheloni, MSc Cristina; Roviglioni, MSc Raffaella.
The organic system is urging the use of organic seeds in order to complete its integrity  and  enhance its reliability. The VIFP Organic Revision offered the possibility to investigate on the different issues related to organic seeds production and use: alternative seed treatments methods; variety availability; derogation regime in several EU Member States and causes for non-use of organic seeds. The results indicate the extreme difficulty the organic vegetable sector will suffer in case it is decided to stop the derogation regime and compell producers to use exclusively organic seeds.

Provedor de dados: 21
Autores: Brandt, Horst; Baulain, Ulrich; Brade, Wilfried; Lapp, Judith; Weißmann, Friedrich.
The aim of the present study including 190 organic fattening pigs of varying Duroc gene portion (0 %, 25 %, 50 %, and 75 %) was to analyze various meat and fat quality characteristics in order to deduce the optimal Duroc gene percentage in relation to different marketing goals. Increasing Duroc gene portions resulted (i) in increasing intramuscular fat contents, (ii) in improved meat quality characteristics (sensory properties, pH, electrical conductivity), (iii) in slightly increasing levels of saturated fatty acids, and (iv) in decreasing levels of mono-unsaturated fatty acids. It is concluded that Duroc gen portion should exceed 50 % only in marketing systems with a payment system including meat quality criteria.

Comparison of traditional and genomic breeding programs for organic and low input dairy cattle accounting for traits relevant in different macro-climatic zones
Provedor de dados: 21
Autores: Frevert, H.; Yin, T.; Simianer, H.; König, S.
In the past decade, successful selection on production traits for dairy cattle has greatly increased milk production. Recently, selection indices for female fertility were gradually and increasingly introduced into the overall breeding goals for dairy cattle (Miglior et al., 2005).  As a by-product of fermention in ruminants, enteric methane emissions (ME) should also be controlled and mitigated due to their contribution to global warming (Forster et al., 2007) and as a cause for inefficient use of dietary energy.  Moderate heritabilities ranging between 0.30 and 0.35 for predicted and real measurements of ME were reported for dairy cows and ewe lambs (de Haas et al., 2011; Pinares-Patiño et al., 2011), indicating that a heritable component for ME is...

Gebrauchskreuzungen - ökologische Nischenproduktion zur Erhaltung gefährdeter Haustierrassen?
Provedor de dados: 21
Autores: Vogt-Kaute, Werner; Damme, Dr. Klaus; Schreiter, Ruben.
In einem Testversuch wurden 3 Hähne der gefährdeten Hühnerrasse Mechelner mit 30 Lohmann braun Elternhennen gekreuzt. Es wurde die Leistung beider Geschlechter geprüft. Das Zielgewicht von knapp 2 kg bei den Hähnen wurde nach 84 Tagen erreicht bei einer Futterverwertung von 1:2,6. Das entspricht einer täglichen Zunahme von 23,4 Gramm. Die Hennen legten 248 Eier in 365 Produktionstagen und 268 Eier in 402 Produktionstagen pro Anfangshenne. Die Ergebnisse zeigen, dass die Kreuzung einer schweren Hühnerrasse mit einem Hybridelterntier eine akzeptable Fleisch- und Legeleistung erreichen kann. Jedoch sind die Ergebnisse aufgrund der geringen Anzahl an Hähner eher exemplarisch als für die gesamte Mechelner Rasse gültig.

Nachhaltige Verbesserung der Verfügbarkeit ökologisch vermehrten Gemüsesaatguts für den Erwerbsanbau durch on-farm Erhaltung, Züchtung und Vermehrung
Provedor de dados: 21
Laut EU-Öko-Verordnung ist es nicht zulässig, konventionell vermehrtes Saatgut im Ökologischen Landbau einzusetzen, solange biologisch vermehrtes Saatgut einer Sorte zur Verfügung steht. Das Problem im Gemüseanbau liegt jedoch in der Verfügbarkeit eines ausreichenden Sortiments an Gemüsesorten. Beim ökologisch produzierten Gemüsesaatgutangebot besteht dementsprechend eine Lücke. Bei steigendem Öko-Anteil am gesamten Gemüseabsatz im LEH ist hier Handlungsbedarf geboten. Mittels des Projekts soll bei unmittelbar geeigneten Sorten eine Erhaltungszucht unter Berücksichtigung der sortenrelevanten Eigenschaften als Grundlage eines Nachbaus unter ökologischen Bedingungen erfolgen, sodass hier direkt eine Erweiterung des Öko-Sortiments realisiert werden kann....

An Approach to Organic Plant Breeding of Cabbage and Cauliflower
Provedor de dados: 21
Autores: Chable, Dr Véronique.
Plant breeding activity has to be considered in the context of the agricultural system. The organic agriculture (OA) is more than a way of production: it is consistent with an ethics of the place and role of the man in the nature. Working for OA means to prefer a holistic approach with a ecological vision of the plant and animal in their environment to an analytic approach with a biochemical vision of the living beings.  The variety plays at least two roles in the organic way of production: (i) an ecological adaptation of the crop and the keeping of the environment equilibrium in the planting, (ii) a valorisation of products from a soil and a savoir-faire. Moreover, the breeders have to take in account the respect of the natural crossing barriers and the...

Adaptation of lupins for Northern European maritime conditions
Provedor de dados: 21

Lupin as a grain crop has been restricted in growing area to more continental conditions due to their indeterminate growth form, which in maritime Northern European areas causes excessive vegetative development, late and uneven ripening and lodging. However, new reduced branching types provides better possibilities for adaptation to these conditions, and preliminary results indicates potential seed yields up to 5-6 tons per ha in the narrowed leafed lupins (Lupinus angustifolius) and an acceptable stable and early ripening.

Vergleich von Hybriden und Populationssorten bei Lagerweißkohl unter den Bedingungen des Ökologischen Landbaus
Provedor de dados: 21
Autores: Elers, Barbara.
Ein zweijähriger Sortenversuch bei Lagerweißkohl unter den Bedingungen des Ökologischen Landbaus zeigt im Mittel der Jahre und Wiederholungen signifikante Sortenunterschiede in fast allen geprüften Merkmalen. Er wies aber ebenso in allen geprüften Merkmalen keine Vorzüglichkeit der Hybriden aus. Das bedeutet, das im Ökologischen Landbau ohne Ertrags- und Qualitätsverlust samenfeste Sorten angebaut werden können.

Suitability of traditional and conventional pig breeds in organic and low-input production systems in Europe: Survey results and a review of literature
Provedor de dados: 21
Autores: Leenhouwers, J. I.; Merks, J.W.M.
For many years, there has been debate about the suitability of traditional and conventional pig breeds in low-input and organic production systems. This review compiles reproductive and finishing performance of traditional and conventional breeds in low-input and organic production systems in Europe, based on literature studies and farm surveys until 2010. In comparison with traditional breeds, conventional breeds wean many piglets, have efficient and fast growth and lean carcasses. They thrive well in North West European climatic conditions with temperate summers and mild winters. Optimal housing may be indoors with outdoor runs, because this provides a controlled environment in which large litters are more easily managed. The lean meat of conventional...

Ekologisk sortprovning av spannmål, trindsäd, oljeväxter, vallgräs och potatis
Provedor de dados: 21
Moderna sorter är framtagna för att passa i ett lantbruk med stora insatser av kväve och ogräsmedel. Vi saknar erfarenheter om hur nya sorter fungerar utan dessa hjälpmedel. I den ekologiska sortprovningen provas därför sorterna i försök som ligger på ekologiska lantbruk. Resultaten har visat att många högavkastande sorter som har fungerat väl i konventionell odling, även har fungerat bra i ekologisk odling och där gett god avkastning och god konkurrens mot ogräset. Detta gäller dock inte generellt, utan t.ex. kortvuxna sorter har blivit ogräsbemängda och tappat mycket i avkastning. Resultaten visar därför att det är av stor vikt att prova sorterna i ekologisk odling som ett komplement till den konventionella sortprovningen....

First EUCARPIA Workshop on Implementing Plant - Microbe Interaction in Plant Breeding
Provedor de dados: 21
The workshop aims at creating a network among plant breeders and researchers of different disciplines to explore the potential of utilizing plant microbe interaction in plant breeding.  In recent years, plant‐associated microbial communities have received considerable attention in research for their ability to improve crop productivity and stability. It is now well recognized that all plants, and nearly all tissues within the plant, are inhabited by a variety of microorganisms. Many of them offer benefits to the host, improving nutrient uptake, preventing pathogen attack, and increasing plant growth under adverse environmental conditions. In return these microorganisms receive shelter from the surrounding environment and access to a carbon‐rich food...

The accuracy of genomic prediction determines response to selection. It has been hypothesized that accuracy of genomic breeding values can be increased by a higher density of variants. We used imputed whole-genome sequence data and various single nucleotide polymorphism (SNP) selection criteria to estimate genomic breeding values in Brown Swiss cattle. The extreme scenarios were 50K SNP chip data and whole-genome sequence data with intermediate scenarios using linkage disequilibrium-pruned whole-genome sequence variants, only variants predicted to be missense, or the top 50K variants from genome-wide association studies. We estimated genomic breeding values for 3 traits (somatic cell score, nonreturn rate in heifers, and stature) and found differences in...

Organic seed production and seed regulation
Provedor de dados: 21
Autores: Borgen, Anders.
Organic farmers must use organic seed material if such seed are available. If not available, conventional seeds can be used. This request exists in all accredited standards for organic farming. In the EU-regulation on organic production methods, the derogation from the use of organic seed material will only exist until the end of 2003. After this date only organic seed material may be used according to the present formulation.    Only a few countries in the EU have an organic seed production able to supply the market for organic seed material. It takes many years to develop a well functioning market for organic seeds. It is therefore unlikely that the derogation for the use of organic seed material will not be extended, since a majority of countries in the...

This study investigates meat quality of four autochthonous Swiss ovine breeds, White  Alpine (WAS, n=15), Walliser blacknose sheep (SN, n=8), Engadine sheep (EN, n=9)  and the Mirror sheep (SP, n=10). Especially for the latter two breeds, which are rare  and endangered, information about meat quality and constitution is important for  merchandising issues. All lambs (LW 20-25 kg) of each breed were fattened on pasture  for 208 d and subsequently slaughtered. Evaluations were carried out for slaughter  yield and classifications, pH-value, colorimetry (L*a*b*-System), shear force (Warner  Bratzler method) and cooking losses in the Musculus longissimus dorsi. The results  showed no meat quality defects in any breed. The main differences between breeds  arose...

Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.; Janmaat, Leen; Zeelenberg, Arend.
In the Netherlands the organic sector keeps growing, but organic potato production is lagging behind. This is due to the relatively high disease pressure from Phytophthora infestans, which causes foliage and tuber late blight. For organic potato growers this disease still forms a major cropping risk.  In the potato breeding programme Bioimpuls, the Louis Bolk Institute and Wageningen UR are working together with breeding companies and farmer-breeders to develop robust cultivars that are resistant to Phytophthora. Thanks to these new cultivars, organic growers now have more chance of yield security. The next step is to collaborate with organic wholesalers and retailers to make sure that the new cultivars reach the shop shelves and consumers’ plates. In the...

Regulation of 3β-Hydroxysteroid Dehydrogenase/∆5-∆4 Isomerase: A Review
Provedor de dados: 21
Autores: Rasmussen, Martin Krøyer; Ekstrand, Bo; Zamaratskaia, Galia.
This review focuses on the expression and regulation of 3β-hydroxysteroi ddehydrogenase/Δ5-Δ4 isomerase (3β-HSD), with emphasis on the porcine version. 3β-HSD is often associated with steroidogenesis, but its function in the metabolism of both steroids and xenobiotics is more obscure. Based on currently available literature covering humans,rodents and pigs, this review provides an overview of the present knowledge concerning the regulatory mechanisms for 3β-HSD at all omic levels. The HSD isoenzymes are essential in steroid hormone metabolism, both in the synthesis and degradation of steroids.  They display tissue-specific expression and factors influencing their activity, which therefore indicates their tissue-specific responses. 3β-HSD is involved in the...

Reproductive Management of Dairy Cows with Particular Reference to Organic Systems
Provedor de dados: 21
Autores: Diskin, Michel G.; Kelly, Frank.
Reproductive efficiency is a major factor affecting production and economic efficiency indairy herds. In seasonally calving herds the requirement of good reproductive performance is of greater importance than in  other production systems in order to maximally exploit the use of grazed grass in the diet of the cow. Reproductive  performance of lactating dairy cows worldwide has declined over the past 30 years in association with selection for milk yield. There is increasing and consistent evidence to  suggest that at least some part of the decline in cow reproductive performance is related to underlying changes in reproductive physiology caused by high milk production and or negative energy balance (NEB) in early lactation. Organic systems of milk...

This report describes the results of research into the vision of breeding systems within organic agriculture in the Netherlands. The purpose of the research was to arrive at a vision for breeding in organic agriculture by means of interviews and discussions with organic livestock farmers and social organisations.    The research was prompted by the fact that, as things stand, organic livestock farmers generally have to rely on the conventional breeding supply. Neither the breeding method not the animal type produced meet the requirements of organic agriculture. Interest in breeding has increased because organic agriculture is expanding, and as yet too little attention has been paid to the development of specific organic breeding programmes and associated...

Genotype and environment interaction on yield and quality parameters of organically grown winter wheat – Triticum aestivum L. genotypes
Provedor de dados: 21
Autores: Dashbaljir, Ichinkhorloo; Liebhard, P.; Hartl, W.; Loeschenberger, F.; Weinhappel, M.
The interaction of genotype and environment upon yield and quality parameters of eight winter wheat (Triticum aestivum L.) genotypes was studied under organic conditions in Austria over two growing periods, 2001/2002 and 2002/2003, respectively. Two sites that have significantly different climatic conditions, Innviertel and Marchfeld, were chosen for the field experiment.   Study site weather and soil conditions are important yield-affecting factors. Although the yield of Marchfeld-grown genotypes were lower, they had shown higher quality parameter values. Soil moisture conditions increase the grain yield but decrease its quality. To obtain seed with higher quality, a production site with favourable climate conditions should be chosen.

Produkce osiv obilnin v ekologickém zemědělství
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Janovska, Dagmar; Prokinová, Evženie; Honsova, Hana; Kas, Martin; Moudry, Jan.
Stěžejní legislativní normy Nařízení Rady (EC) No. 834/2007 a nařízení komise (EC) No. 889/2008 udávají podmínky použití osiva v ekologickém zemědělství. Povoleno je až na výjimky pouze použití ekologicky certifikovaného osiva pro zakládání porostů. Osivo proto musí pocházet z matečních rostlin, které byly po jedno vegetační období pěstovány v systému ekologického zemědělství. Problémem je ale vysoká náročnost množení osiv v ekologickém zemědělství, protože množitelský porost musí splnit podmínky pro uznávací řízení stejné jako konvenční porost, ale bez podpůrných prostředků konvenčního zemědělství (agrochemikálie). Ekologičtí zemědělci by měli používat pouze ekologicky certifikované osivo, v praxi ale mohou požádat u udělení výjimky pro setí konvenčního...

Genetic variation in specific root length in Scandinavian wheat and barley accessions
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Gahoonia, Tara Singh.
Specific root length (SRL, m root g-1 root dry matter) was studied in a broad selection of old and presently grown accessions of spring wheat and barley from Norway and Sweden, at sub-optimal phosphorus conditions in nutrient solution and soil. The results indicated that genotype did not have a significant effect on SRL. A close relationship between root length (RL) and root weight (RW) was found, and more than 70% of the variation in root lengths was explained by root weights of representative and homogenous root samples. In nutrient solution, the relationship between RL and RW was described by the regression equations RL = 0.32RW – 0.19 (R2 = 0.74) for wheat and RL = 0.20RW + 0.73 (R2 = 0.56) for barley. In the soil experiment, the relationships between...

Genetic evaluation of carcass traits in dairy cattle
Provedor de dados: 21
Autores: Mattalia, Sophie.
Two new genetic evaluations on carcass data, extracted from the Normabev database, have been developed by the UMT 3G (Gestion Génétique et Génomique des populations bovines). The first (VB) is a multibreed evaluation of sires on their ability to produce veal calves. It evaluates sires of dual-purpose breeds Montbeliarde (MON) or Normande (NOR) and sires of beef breeds mated with dairy cows. The second (JB) evaluates sires of the MON, NOR and Simmental (SIM) breeds on their ability to produce young bulls for slaughter. The JB evaluation considers three traits simultaneously (carcass weight, age at slaughter and carcass conformation), the VB four (the same three, plus meat color). Heritability estimates are moderate to quite high for carcass weight and...

Entwicklung des Befalles mit Weizensteinbrand (Tilletia caries) bei Saatgut in der Biosaatgutanerkennung in Österreich und Qualitätsvergleich zu Nachbausaatgut
Provedor de dados: 21
Autores: Weinhappel, Manfred; Riepl, Ernestine.
Common Bunt (Tilletia caries) is a mainly seed borne disease and causes high losses in organic wheat and spelt production. Due to the basic role of seed health in disease prevention, seed quality aspects have to be focussed strictly in organic farming.  In the scope of these studies, Tilletia results of 1291 wheat seed lots and 298 spelt wheat lots obtained from officially organic seed production from 2000 to 2012 have been analysed. The data indicated significantly the increasing spread of Tilletia caries in seed production in the last years, nevertheless in 2012 a high rate of more than 90% of the tested lots still corresponds to the requirements for untreated seed according to the Austrian Seed Regulations (threshold level 10 spores/kernel).

Genetic aspects of heat stress in pigs expressed in fertility traits
Provedor de dados: 21
Autores: Bloemhof, S.; Mathur, P.K.; van der Waaij, E.H.; Leenhouwers, J.I.; Knol, E.F.
The number of pig breeding programs has reduced in recent years. This leads to a small number of pig breeding companies producing pigs for many different environments. Therefore, pig breeding programs have to breed pigs capable of facing heat stress challenges during their productive life. Management practices such as cooling offer one option to reduce heat stress and warrant performance during hot seasons. A more sustainable alternative is to breed sows for improved heat tolerance. When evaluating breeding goals for dam lines we were confronted with different appreciation of two dam lines by pig producers in the Netherlands (temperate climate) and in Spain (warmer climate).These two dam lines, differed in the relationship between ambient temperature and...

Fedtsyreprofilen i mælk fra malkekøer - potentiale og perspektiver
Provedor de dados: 21
Autores: Kargo, Morten; Buitenhuis, Albert Johannes; Munk, Arne.
Projektet SOBcows har i samarbejde med RYK gennem 16 måneder i 2015/16 analyseret for indholdet af fedtsyrer i kontrolmælken fra alle ydelseskontrollerede køer i Danmark. Rapporten præsenterer opgørelser på målingerne og evaluerer potentialet i at bruge viden om mælkens fedtsyreprofil i avl og produktion samt i forhold til fedtsyrernes betydning for human sundhed.  En litteraturgennemgang viser, at fedtsyresammensætningen i komælk varierer betydeligt og er påvirket af en række faktorer relateret til fodring, race og management. Fodring med græs- eller urtebaserede rationer øger mælkens indhold af umættede C18-fedtsyrer, og tilsvarende øger fodring med mættet fedt indholdet af palmitin– og stearinsyre (C16:0 og C18:0) i mælkefedtet.

Autores: Moghaddam, Ali; Raza, Amir; Vollmann, Johann; M.Reza, Ardakani; Wolfgang, Wanek; Gabriela, Gollner; Juergen K., Friedel.
To identify the effective characters and their relative importance in improvement of BNF, two separate field experiments were conducted under irrigated and rain-fed organic managements of dry, Pannonian region of east Austria. The experiments were laid out in an α-lattice design with two replications and 18 genotypes (eight Iranian ecotypes and ten European cultivars). Plant height was positively and significantly correlated with leaf area index (LAI) and shoot dry matter (DM) under both conditions. Positive correlations were found between biological nitrogen fixation (BNF) and shoot DM (r = 0.61** and 0.87**, irrigated and rain-fed management, respectively). Regarding correlation coefficients, high yielding genotypes had taller plants and denser stands,...

Root traits differ between wet- and dry-adapted sets of faba bean accessions selected by FIGS
Provedor de dados: 21
Autores: Khazaei, Hamid; Street, Ken; Abdallah, Bari; Fred, Stoddard.
Grain legumes, such as faba bean (Vicia faba L.), are important sources of protein, particularly for people in developing countries where climate change is expected to result in higher temperatures and changing precipitation patterns. Among grain legumes, faba bean is thought to be relatively sensitive to drought. Faba beans are important legumes in the crop rotations of organic farming. Deeper roots and larger root biomass have been shown to be important contributors to crop performance under drought conditions. Thus root traits could be used as the selection criteria for drought adaptation. During 2010–2011, two sets of faba bean accessions, from ‘wet’ and ‘dry’ regions, each containing 201 accessions, were chosen using the Focused Identification of...

Möhren: Populations- und Hybridsorten im Vergleich
Provedor de dados: 21
Autores: Arncken, Christine.
Hybridzüchtung ist seit Mitte des letzten Jahrhunderts weltweit auf dem Vormarsch. Im Bio-Landbau wird sie jedoch aus politischen, ethischen und ökologischen Gründen hinterfragt und es wird befürchtet, dass sie die innere Qualität von Kulturpflanzen be-einträchtigt (Arncken 2005). Manche Bio-Züchter wie die SATIVA (CH) und der Verein Kultursaat e.V. (D) setzen ganz auf offenbestäubende (OP-) Sorten, wofür die Züch-tung weniger aufwendig ist, und nehmen dafür gewisse Nachteile (Ertrag, Sortierung) in Kauf. Wir untersuchten, ob und wie große Unterschiede zwischen den resultierenden Sortentypen bei Möhren vorhanden sind.

Foredling av planter og husdyr er en kontinuerlig prosess, og en forutsetning for dagens landbruk. Men satsingen på høye avlinger ved godt tilrettelagte betingelser kan redusere evnen til å gi brukbar avling under varierende forhold. Kan vi få mer robuste kornsorter hvis vi går andre veier i planteforedlingen, og satser bevisst på et stort genetisk mangfold? COBRA-prosjektet har bidratt til å undersøke dette.

Autores: Fontaine, Laurence; Rolland, Bernard; Bernicot, Marie-Hélène.
Bread winter wheat is one of the most important cash crops for French organic farmers. Nevertheless, most of varieties available on the market were bred for conventional farming systems (with high inputs of mineral fertilizers and chemicals for crop defense). In order to obtain correct levels of yield and quality, it is important i) to screen current varieties to find the best suited for organic conditions, and ii) to rapidly obtain suitable varieties that are specifically bred for organic farming conditions. Bread wheat variety trials under organic conditions have been coordinated since the year 2001, to centralize and evaluate results at national level. The ringtest not only aims to compare varieties, but also to support organic breeding, as it provides...

Introductory considerations on crop diversity
Provedor de dados: 21
Autores: Borgen, Anders.
Modern society faces decreased biodiversity in nature caused by increased uniformity in agriculture, and health related problems with nutrition caused by industrialisation in food production. Conversion to organic farming increases biodiversity, because of diversification in crops and decreased intensity in control of weed and pests, and increase biochemical diversity within food products because of decreased nitrogen application in field. The author argues that the positive effects of in organic farming can be further improved by improved genetic diversity within the crop. Inter-cropping and variety mixtures are already  used by some farmers, but diversity within the crop can be further improved by development of composite cross populations, composition...

Ziel des Beitrags ist eine Übersicht über aktuelle Initiativen zu Zweinutzungshühnern in Deutschland. Alternativen zum Töten der männlichen Eintagsküken der Legehybriden erscheinen ethisch geboten. Ein kurzfristiger Ansatz zur Reduzierung dieses Problems ist eine verlängerte Nutzung der Legehennen durch Legepausen. Einige Naturkostgroßhändler verlangen einen Aufpreis für die Eier, um damit die Mast der männlichen Legehybriden finanziell zu unterstützen. Eine dritte Lösung sind spezielle Zweinutzungsherkünfte; es werden Beispiele für Rasse- und Hybridhühner vorgestellt. Ferner werden Wirtschaftlichkeitskalkulationen für drei Herkünfte präsentiert.

Autores: Arncken, Christine; Schmid, Otto.
On April 19th, 2006, the 100 delegates of Bio Suisse, the Swiss organic umbrella organization, voted to ban Hybrid varieties in organic cereals (except maize). This decision primarily concerns rye. Organic rye is grown on only 250 ha, about 20% of which is sown to hybrid varieties at present. About 60% of total organic demand is imported. Hybrid varieties of the other cereals are not yet being grown. The delegates decided that it is time to act now to send a signal to breeders and to the international organic community before the alternatives to hybrids vanish.

In the scope of a research project, official data from the certification of organic seed in  Austria from 1999 to 2007 were analysed to determine the most important factors  effecting seed quality and leading to rejection of certification. Data from 4684 seed  multiplication fields and 3262 seed lots were analysed.  Weed seeds and wild oats (Avena fatua) have little effect on the quality of finished  seed due to highly effective seed processing plants and risk-based seed testing. In  cereal seeds the most frequent reason for rejection of certification in the category  Other Seeds by Number is Other Cereal Seeds. An important criterion resulting in  frequent non-certification of organic seed is the level of infection from seed-borne and  seed-transmitted...

The purpose of this study was to evaluate the effect of temperature and different levels of available phosphorus (aP) on the expression of nine genes encoding electron transport chain proteins in the Longissimus dorsi (LD) muscle of pigs. Two trials were carried out using 48 high-lean growth pigs from two different growth phases: from 15 to 30 kg (phase 1) and from 30 to 60 kg (phase 2). Pigs from growth phase 1 were fed with three different levels of dietary aP (0.107%, 0.321% or 0.535%) and submitted either to a thermoneutral (24°C and RH at 76%) or to a heat stress (34°C and RH at 70%) environment. Pigs from growth phase 2 were fed with three different levels of dietary aP (0.116%, 0.306% or 0.496%) and submitted either to a thermoneutral (22ºC and RH...

Autores: Rolland, B.; Al Rifai, M.; Bataillon, P.; Fontaine, L.; Gardet, O.; Oury, F. X.
The objectives of the French national institute of agronomy (INRA) cereals programme are to evaluate genetic material from breeding programmes for low input systems (high disease and lodging resistance, low seeding rate, good response to low level of nutrients, standard quality) including organic conditions.  The aim of the study is to define important agronomic characteristics of cultivar adapted to organic farming. Despite some relation with agronomical performances in low input system, weeds competitiveness, productivity and baking quality are specific in organic farming. Productivity and baking quality are linked to nutrient acquisition ability: nitrogen uptake and nitrogen-use-efficiency. The selection of new lines based on weed competition and N...

Late-acting self-incompatibility in Capparis retusa (Capparaceae), a species of Chaco woodland in NE Argentina
Provedor de dados: 88
Autores: BIANCHI,MARTA B.; GIBBS,PETER E.
The reproductive biology of Capparis retusa was studied by means of controlled pollination experiments and fluorescence microscopy observations of post-pollination events. Self-pollinated flowers mostly failed to form fruits despite the fact that self-pollen tubes grew to the ovary and penetrated ovules within 24 h. Since embryo development to globular stage was observed in some self-fertilized ovules it was concluded that control of self-fertilization in this species occurs by some kind of post-zygotic mechanism.

Provedor de dados: 95
Autores: Caieiro,Juliana Terezinha; Panobianco,Maristela; Bespalhok Filho,João Carlos; Ohlson,Osvaldo de Castro.
Plant breeding is generally done through sexual reproduction even when the species is propagated asexually for commercial exploitation, as for example, in sugarcane. Therefore, the development of procedures to evaluate sugarcane seed viability is important for plant breeding programs. The objective of this research was to develop a methodology for analyzing the viability of sugarcane seeds (Saccharum spp.). Three crosses were used, two biparental crosses and one polycross. For the germination test study, two substrates (paper and sand) and three constant incubation temperatures (25 ºC, 30 ºC and 35 ºC), in the presence of constant light and also an alternating temperatures (20-30 ºC), with 8 hours light (30 ºC) and 16 hours darkness (20 ºC), were studied....

ABSTRACT This study aimed at estimating the heritability of age at first calving and of performance traits included in the selection index and the genetic correlations between age at first calving and these performance traits. Data were extracted from the Conexão Delta G database and only data from herds in which heifers were bred younger than 24 months of age were used, resulting in a file with 331,310 evaluated animals. The following traits were included in the analyses: age at first calving, birth to weaning gain, post-weaning weight gain, visual scores of conformation, precocity, and muscling evaluated at weaning and in yearling heifers. Covariance components were obtained by bi-character analyses between traits. An alternative age at first calving was...

Forage yield and persistence of red clover progenies in two environments
Provedor de dados: 63
Autores: Montardo,Daniel Portella; Dall'Agnol,Miguel; Paim,Nilton Rodrigues.
Red clover (Trifolium pratense L.) is one of the most important temperate legume species, used to lessen the lack of forage during the critical fall-winter period in Rio Grande do Sul, RS, Brazil. However, its utilization has been restricted mainly because of its lack of persistence. This work evaluates the dry matter yield and persistence of red clover half-sib progenies in two physiographic regions of RS: "Depressão Central", in Eldorado do Sul and "Encosta Superior do Nordeste", in Veranópolis. Experiments were carried out for two growing seasons and results were compared to two red clover commercial checks, Qüiñequeli and Estanzuela 116. The region of Veranópolis was more adequate for red clover forage production, enabling better yield and persistence....

The soybean [Glycine max (L.) Merrill] crop holds a prominent position in the Brazilian economy because of the extension of the planted area and volume of grain production, but the beany flavor has been a limiting factor for soybean derivatives consumption by western population. This flavor is produced mainly by action of lipoxygenase enzymes (Lox1, Lox2 and Lox3), present in some commercial varieties. The genetic elimination of the alleles that codify these enzymes is the most appropriate way to avoid problems associated to this deleterious flavor. To elucidate the effect of seed lipoxygenase elimination on the resistance to plant pathogens, normal varieties of soybean (FT-Cristalina RCH, Doko RC and IAC-12) and their backcross-derived lines, both with...

In vitro sensivity of fig plantlets to gamma rays
Provedor de dados: 63
Autores: Ferreira,Ester Alice; Pasqual,Moacir; Tulmann Neto,Augusto.
Fig breeding programs through conventional methods are rare in many countries, e.g. Brazil, since the wasp Blastophaga psenes, which is responsible for the natural pollination, is not present. For these cases a low cost alternative for the breeding program is the induction of physical mutagenesis by radiation. The sensivity of fig explant buds of different sizes to gamma radiation were evaluated. Fig plantlets "Roxo de Valinhos" already established in vitro were classified by size in 2.5 to 4.5 cm, 5 to 9 7 cm and 8 to 10 cm long, and irradiated with: 10, 20, 30, 40 and 50 Gy doses. After irradiation each plantlet was cut in pieces containing one-bud and transferred to WPM culture medium, according to the bud position: medium and apical. Explants were...

Relationship between seed technology research and federal plant breeding programs
Provedor de dados: 63
Autores: Krzyzanowski,F. C.
This paper deals with the contributions seed technology can provide for soybean breeding programs for seed quality. Efforts can be placed on seed quality assurance (DIACOM) to assist the production system, from genetic up to certified seed in releasing a product of high quality. Another approach is the development of screening methods, based on seed technology tests (vigor tests), for selecting genotypes according to different traits relating to seed quality. An understanding of seed quality mechanisms, such as seed-coat properties, pod-wall permeability, seed and pod resistance to fungi infection , seed shriveling and cell wall permeability, will help to define the screening procedures for this characteristic. It has been one of the most important...

Cuidado parental de Sula leucogaster (Boddaert) (Aves, Pelecaniformes, Sulidae) nas Ilhas dos Currais, Paraná, Brasil
Provedor de dados: 104
Autores: Martins,Flávia de Campos; Dias,Manoel Martins.
In Sula leucogaster (Boddaert, 1783) it happens a brood reduction from two to one egg. The eggs hatch asynchronously and it is rare for the second chick to survive for long. A quantify parental investment is proposed and the differences between males and females of Sula leucogaster is verified for to help to understand the brood reduction. The studies were conducted on Ilhas dos Currais, Paraná, Brazil, where a total of 140 nests were studied. Males and females shared the breeding care period. However, females invested about 8% more on incubation than males (c² = 7,37; c² critic = 3,842). Time of absence in the nest for females was larger than for males (c² = 13,9; c² critic = 3,842). This is probably a function of females bringing food to chicks more...

Genetic breeding on the bee Melipona scutellaris (Apidae, Meliponinae)
Provedor de dados: 36
Autores: Barros,José de Ribamar Silva.
A selection of queens of Melipona scutellaris through the most productive colonies were carried out during eight months in an orange honeyflow. Each of the colonies was evaluated by its production, that is, the gross weight production ( pollen, brood, geopropolis and wax of each hive). With this data a coefficient of repeatability was estimated by the intraclass correlation method, obtained r = 0.835 ± 0.071. The repeatibility is very high showing that the analysed data (production) is repeatable. Selection was then carried out using the regression coefficient of each colony and the respective production gain. Using these data the colonies were divided into three groups according to the method Vencovsky and Kerr (1982): a with the colonies of highest...

Provedor de dados: 54
Autores: Oliveira,L.B.; Ramalho,M.A.P.; Abreu,A. de F.B.; Ferreira,D.F.
Six common bean cultivars were crossed in diallel and the segregant populations were assessed in the F2 and F3 generations to compare methodologies for parental selection in a breeding program based on hybridization. The cultivars involved in the diallel were A 114, A 77, ESAL 686, Milionário, Carioca, and Flor de Mayo. The segregant F2 and F3 generations were assessed on the experimental campus of the Universidade Federal de Larvas, in July 1994. It was found that the cultivars differed in their general combining ability (GCA). Flor de Mayo, which belongs to the Durango race, had the largest positive GCA estimate for grain field, and the cultivars from the Mesoamerican race, Milionário and A 114, the smallest GCA estimates. For flowering, the cultivar...

Sgrmate: for maximizing genetic gain and controlling inbreeding.
Provedor de dados: 14
Autores: LOBO, R. N. B.
Genetic evaluations in animal breeding are essential for identifying superior individuals, who can be selected to compose the next generation. The indication of sires and dams of proven genetic value improves the efficiency of production systems. On the other hand, the use of few animals in the selection process can increase the inbreeding of the herds, which can reduce the animals’ vigor and reduce future genetic variability. Additionally, with the availability of genetic value from several animals, the decision of how to combine these parents for the possibility of greater genetic gain is not such a simple task. Imagine having to combine 20 sires with 300 dams, who should be mated with whom? The availability of a tool to carry out this work has a great...

The objective of this study was to evaluate the genetic variability of rice (Oryza sativa) landraces collected in Brazilian small farms. Twelve simple sequence repeat (SSR) markers characterized 417 landraces collected in 1986, 1987 and 2003, in the state of Goiás, Brazil. The number of landraces with long and thin grain type increased in the evaluated period, probably due to market demand. Based on the molecular data, the genetic variability increased during this period and, as per to the factorial correspondence analysis, most of the accessions were grouped according to the year of collection. The incorporation of modern rice cultivars in landrace cultivation areas and the selection carried out by small farmers are the most probable factors responsible...

In exploring the existing genetic variability in commercial germplasm, germplasm has been proven to be an excellent alternative to obtain inbred lines in order to provide superior new hybrids in the future. In this sense, the objective of this study was to estimate the genetic distance among commercial processing tomato hybrids via agronomical and quality postharvest fruit traits with the aim of suggesting promising crosses for the formation of base populations for tomato breeding. Ten hybrids of processing tomato were evaluated in a complete randomized block design with three replicates. In total, eleven agronomic and postharvest...

Tolerance to high temperature in F5 inbred lines of tomato
Provedor de dados: 75
Autores: Santos,Lucas S; Melo,Roberto A; Santos,Paulo R; Carvalho Filho,José LS; Menezes,Dimas.
High temperatures in the growing tomato have caused a reduction in fruit set and consequently productivity. This work aimed to evaluate F5 lines of tomato to fruit set and high temperature tolerance in two culture environments. Two experiments were carried out, one in cultivation in greenhouse and the other in the field conditions, from February to June 2012. We evaluated 20 lines F5 of tomato, originating from the segregation of hybrid SE 1055 F1, developed for the hot and humid conditions, with resistance to Fusarium oxysporum f.sp. lycopersici race 2, the tomato mosaic virus (ToMV), the Verticilium dahliae and geminivirus (TYLCV) and the control cultivar Yoshimatsu and own hybrid SE 1055 F1. The experiment was performed in a randomized blocks design...

Although Brazil is the major producer and exporter of beef in the world, the rangelands are cultivated with varieties obtained by selection on germplasm and conventional breeding. Only lately genomic information started to be used in the tropical forage breeding programs mostly because of the genome complexity and costs. Urochloa ruziziensis is a sexual autotetraploid forage that has a significant role in integrated systems that are currently important in the agribusiness in certain regions of Brazil and is essential as female parent in other Urochloa spp. breeding programs. Thus, this work intends to use the Genotyping by Sequencing (GBS) approach to identify SNP markers to construct the first map of the species and estimate breeding values for Genomic...

Genetic improvement of fish: Achievements and challenges for tomorrow
Provedor de dados: 5
Autores: Vandeputte, Marc; Baroiller, Jean-francois; Haffray, Pierrick; Quillet, Edwige.
Genetic improvement is a major contributing factor in developing efficient aquaculture, as it is in other forms of animal production. Moreover, as most fish species are only slightly domesticated, the potential gains are very large. Many of the current methods, developed during the XXth century, are classically used in livestock rearing (choice of breeds, crossbreeding, selective breeding). Others are much more specific to aquatic organisms (genetic control of sex, sterilization through triploidization). The spread of selected lines in aquaculture has been effective only since the 1990s, with lines selected essentially on growth and producing some impressive results. Transgenesis, although technically feasible on growth rate, is not used in practice and...

Multiple queens in founding colonies of the neotropical ant Pachycondyla striata smith (Formicidae: Ponerinae)
Provedor de dados: 82
Autores: Rodrigues,MS; Vilela,EF; Azevedo,DO; Hora,RR.
In social insects, the typical mode of colony foundation occurs when a single queen is inseminated by a male and establishes a new colony, although we can find interspecific and intraspecific variations in queen number and queen-mating frequencies in a single colony. This study aimed to verify the queen number in Pachycondyla striata (Smith) colonies and to evaluate the level of aggressiveness among workers. We collected 14 colonies of P. striata. The behaviors of individuals from five multiple-queen colonies maintained in laboratory were studied by the method of scan sampling. In order to evaluate aggressiveness, dyadic encounters among heterocolonial and homocolonial workers were performed. The results showed that colonies of P. striata can have two or...

Autores: Gruber, Harriet; Wuttke, Matthias.
Ungünstige Wachstumsbedingungen oder ein früher Befall mit Krautfäule (Phytophthora infestans) begrenzen sehr häufig die Vegetationszeit im ökologischen Kartoffelanbau und beeinträchtigen den Marktwareertrag. In solchen Jahren könnten Sorten mit frühem Knollenansatz diese kurze Vegetationszeit für die Ertragsbildung besser nutzen als Sorten mit spätem Ansatz und langsamer Jugendentwicklung.   Für den ökologischen Landbau ist über den zeitlichen Verlauf der Ertragsbildung vergleichsweise wenig bekannt. Daher war das Ziel der Untersuchungen zu klären, ob es Sortenunterschiede in der Ertragsbildung gibt, wann diese am besten feststellbar sind und ob Sorten über die Zeiternten ähnlich reagieren. Darüber hinaus sollen zusätzliche Informationen über...

European perspectives of organic plant breeding and seed production in a genomics era.
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.; Wilbois, K-P.; Østergård, H.
For further optimisation of organic agricultural systems, more focus is required on  organically produced seeds and the development of better adapted varieties.  Organic plant breeding and seed production need to comply with the concept of  naturalness as applied in organic agriculture, which not only includes the nonchemical  and agro-ecological approaches, but also the integrity of life approach.  As organic environments are less controllable and are more variable, breeding  should aim at improved yield stability and product quality by being adapted to  organic soil fertility as well as sustainable weed, pest and disease management.  Also the ability to produce economicacceptable seed yield avoiding seed-borne  diseases should be included. On the short...

For the operationalization of the structured, stepwise selection procedure for non-target testing organisms integrated into the new EFSA guidelines for environmental risk assessment of GM plants practicaltools – i.e. ranking matrices – were developed. These tools – some of them are new and some are refinedfrom older ones – were tested using the GM case crop of TC 1507 maize. The selection procedure consists of six steps. The strategy builds on identifying the important ecological functions for the particularcropping system and compiling a species lists according to their ecological functions and presence inthe specific receiving environments. Subsequently, the species numbers are reduced in a systematic,stepwise fashion to a relevant and practical number...

Trial setup and statistical analysis
Provedor de dados: 21
Autores: Büchse, A.; Krajewski, P.; Kristensen, K.; Pilarczyk, W.
The response from field trials is subject to random variation. This means that two neighbouring plots grown with the same variety and treated in the same way will always yield differently. This also applies to all other recordings made on a continuous scale. The size of the differences will depend on several circumstances such as the variability in the soil, variability in the applied fertilizer, historical events and uncertainty in the recording process. This means that a recorded difference between e.g. two varieties may be due to either a true difference in the response of the two varieties or may be due to random variations. In order to help decide whether the difference is caused by the different varieties or by random variation it is necessary to...

Aspekte der Mast- und Schlachtleistung von Schweinen unterschiedlicher Genotypen in Freilandmast auf dem Fruchtfolgeglied Kleegras
Provedor de dados: 21
Autores: Weißmann, Friedrich.
Die ökologische Schweinehaltung ist zur Zeit nur wenig entwickelt. Die Gründe liegen vor allem in Unwägbarkeiten der Erzeugung sowohl in der Ferkelerzeugung als auch in der Schweinemast. Das ist insofern bedauerlich, als sich der Markt für ökologisch erzeugtes Schweinefleisch durch erfolgverheißende Prognosen auszeichnet (Branscheid und Weißmann, 2002). Ein wesentliches Problemfeld in der ökologischen Schweinemast besteht in der nicht ausreichend bearbeiteten Interaktion von betrieblicher Futtergrundlage und genetischer Herkunft der Masttiere im Hinblick auf die ökonomisch erfolgreiche Erzeugung marktfähiger Schlachtkörper- und Fleischqualitäten (= Schlachtleistung) mit der folgenden Begründung:  Derzeit stehen keine explizit für die ökologische...

Low-P solution culture may assist screening of root growth vigor in soil for high nutrient uptake of spring wheat varieties
Provedor de dados: 21
Autores: Wang, Yaosheng; Andersen, Sven Bode; Thorup-Kristensen, Kristian; Jensen, Lars Stoumann; Magid, Jakob.
Root and root hairs of plants have been intensively studied in solution culture; however, correlation of such measurements in solution culture with development in soil is poorly understood. This study compared growth of roots and root hairs as well as uptake of macro- and micronutrients of six spring wheat varieties in solution culture under P stress and P abundance and in a low fertility soil. Results showed that root length and surface area under P stress was significantly positively correlated with that in the low fertility soil, while no such correlation was apparent for root hair length and density. In absolute terms the root length, surface area, root hair length and density of spring wheat varieties were substantially higher in soil than in solution...

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.)
Provedor de dados: 21
Autores: Rasmussen, Martin Krøyer; Klausen, Christina Lindgaard; Ekstrand, Bo.
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the expression of hepatic CYP mRNA (1A2, 2A19, 2C33, 2D25, 2E1 and 3A29), using primary porcine hepatocytes. Of the tested secondary plant metabolites, artemisinin, scoparone, lactucin and esculetin all induced increased expression of specific CYPs, while esculin showed no effect. In contrast, a global extract of chicory root decreased the expression of CYP1A2, 2C33, 2D25 and 3A29 at high concentrations. The results suggest that purified secondary metabolites from chicory affect CYP expression and thereby might...

Autores: Leithold, Dr. B.; Weber, Prof. Dr. W.E.; Schulz, F.; Leithold, Prof. Dr. G.
An annually identical assortment of each of 32 winter wheat varieties and lines bred  under conventional conditions was tested between 2004 and 2007 both in a  conventionally and in an organically managed environment. Previously the assortment  had been evaluated with respect to yield and indirect parameters of baking quality.  The objective was to obtain evidence for a targeted selection of lines for their later use  as bread varieties in organic farming. It was discovered that for a successful selection  of lines for the subsequent cultivation under organic conditions especially the  evaluation of yield must be conducted strictly under the same conditions.

Eignung unterschiedlicher Herkünfte für die ökologische Haltung von Masthähnchen
Provedor de dados: 21
Derzeit besteht im Ökolandbau Uneinigkeit über die Zuchtziele für eine ökologische Geflügelzucht. Die auf einseitige Höchstleistungen gezüchteten Lege- bzw. Masthybriden sind anfällig für Gesundheitsstörungen und mit den zugelassenen Futtermitteln kaum bedarfsgerecht zu füttern. Maßnahmen wie die Zucht einer „Ökohybride“ oder die züchterische Bearbeitung von Rassegeflügel sind allenfalls langfristig möglich. Kurzfristig ist die ökologische Hühnermast auf die vorhandenen Herkünfte angewiesen. Als Alternativen zu den schnell wachsenden Masthybriden kommen langsam wachsende Hybriden oder Rassegeflügel in Betracht. Zu solchen alternativen Herkünften gibt es insgesamt nur wenig Versuchsergebnisse. Dies trifft umso mehr auf Versuche unter den Bedingungen des...

Free range and organic systems provide different circumstances for laying hens than closed houses or cages, where most hens are selected in. An enquiry and farm visits were done in The Netherlands, Switzerland and France in order to find out what genotypes are being used and how they perform. There are differences between countries, systems (organic vs free range) and groups of breeds. There is not just one genotype suitable for organic and free range systems.

Effect of breed suitability, system design and management on welfare &amp; performance in traditional &amp; organic poultrymeat (OF0153)
Provedor de dados: 21
Autores: Gordon, Mrs Sue.
Background  Over the past fifty years broiler production accounted for almost all of the meat chickens produced in the UK.  As a result, only broiler hybrids were available for use by UK producers, and these were not thought to be suited for use in some extensive production systems.  This meant that when consumer demand for extensively produced chicken meat increased in the late 1990s producers were unable to quickly identify and source the most suitable hybrids for UK conditions.  Furthermore, systems of extensive production were still being developed, and little was known about design and management factors affecting range usage.    Project OF0153 aimed to characterise breed suitability for extensive production (free-range, traditional free-range and...

Seed availability for non-GM cotton production - An explorative study
Provedor de dados: 21
This explorative study is an inventory: A first assessment of the problems of accessing organic seed and the contamination of organic cotton seed with genetic modification (GM) in the field. Outcomes of the inventory lead to hypotheses to be tested in further regional workshops. This inventory is an initial step in developing a master plan for safeguarding the availability of organic cotton seed.  Approximately 81% of respondents overall, including 90% of organic farmers who responded, are of the opinion that organic cotton seed is difficult to access. In countries where GM cotton is predominant (the USA, India, China and Burkina Faso) close to 90% of respondents feel it is “difficult” to “impossible” to access organic cotton seed.

Autores: Hospers-Brands, A.J.T.M.; Ji, Yongran; Struik, P.C.; Lammerts van Bueren, E.T.
Kool is een belangrijk gewas in Nederland. Koolsoorten vragen veel stikstof (ca. 300 kg N/ha)voor een goede groei, dikwijls meer dan binnen de huidige regelgeving in een biologische vruchtwisseling kan worden geleverd. Stikstof verhoogt de opbrengst, maar bij een hoog stikstofaanbod bereikt de opbrengst een plafond. Er is in het verleden veel onderzoek gedaan om de bemesting te optimaliseren.

Entwicklung von Maissorten für den Ökologischen Anbau
Provedor de dados: 21
Autores: Jung, Rüdiger; Becker, Heiko; Stever, Mareile.
Mais wird im ökologischen Landbau bisher wenig angebaut, obwohl er sowohl als Futterpflanze als auch als Marktfrucht von großem Nutzen sein könnte. Ein Grund hierfür ist, dass der Anbau unter ökologischen Bedingungen höhere und teilweise andere Ansprüche an dem Mais stellt als der unter konventionellen Bedingungen. Die Konkurrenzfähigkeit gegenüber Unkraut ist dabei das am stärksten ökospezifische Merkmal. Dazu wurden pflanzenbauliche und pflanzenzüchterische Untersuchungen durchgeführt.   In dreijährigen pflanzenbaulichen Versuchen an zwei ökologisch bewirtschafteten Standorten im südlichen Niedersachsen (Reinshof, Wiebrechtshausen) wurden bei verschiedenen Maissorten acht Untersaat-Varianten geprüft. Mit allen UntersaatVarianten konnte die Sprossmasse...

Organic diet and fertility-possible effects of diet on male reproductive parameters
Provedor de dados: 21
Autores: Jensen, Marianne Nygaard.
Lifestyle and environmental exposure to various chemical substances are believed to be, partially, responsible for an apparent increase in reproductive health problems in both wildlife and humans. The incidence in abnormalities in reproduction and – organs is seemingly increasing in many wildlife populations, and the culprit is believed to be various manmade chemicals present in the general environment. Moreover, a large body of evidence points towards human reproductive health being adversely affected. Male reproductive health has apparently been negatively affected and many reports of, for instance, declining sperm counts have been published. As the changes observed are too recent to be attributable to genetics, lifestyle and environmental factors are...

Urgent need for new apple breeding methods  better adapted to low-input agro ecosystems
Provedor de dados: 21
Autores: WARLOP, FRANCOIS; LATEUR, MARC; DAPENA, ENRIQUE.
Due to its perennial statute, fruit sector is the first consumer of plant protection products per hectare. This may also be a direct consequence of a historical cultivar selection that neglected the tree rusticity for years, and mostly encouraged high yield, common quality and aesthetical properties. The ecological footprint of fruit cultivation is therefore very high, and not sustainable. Many fungicides and insecticides shall be used, even in organic farming, to face sanitary problems. Considering the time necessary to create new cultivars, an urgent change of paradigm is needed. The French Ministry recently launched a mission involving many scientists active in this field, to start integrating environmental purposes into the vegetal selection devices....

Muligheter for utfasing av konvensjonelle dyr i økologisk fjørfeproduksjon ved fjerning av unntaksbestemmelsen
Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.
NORSØK fikk i oppdrag fra Regelverksutvalget for økologisk landbruk å skaffe en første oversikt over hvilke konsekvenser og muligheter et krav om utfasing av unntaket for bruk av konvensjonelle dyr vil få for de økologiske produsentene, med hovedvekt på fjørfe. I Norge er det liten økologisk fjørfeproduksjon, men fjørfe er det husdyret som har størst forskjell i dyrevelferd når man sammenligner økologisk og konvensjonell produksjon. NORSØK har intervjuet produsenter, og sendt ut spørreundersøkelser til andre aktører. Hybridene som brukes i økologisk fjørfeproduksjon i dag ser ut til å fungere bra, men det er kun en økologisk kyllingprodusent som har dyr av økologisk materiale fordi de har egne økologiske foreldredyr. For å få fjørfe som er av økologisk...

Provedor de dados: 21
Autores: Konvalina, Petr; Zechner, E.; Moudry, Jan.
Podíl orné půdy stejně jako obilnin v ekologickém zemědělství v České republice je nízký. Z tohoto důvodu nejspíše v dohledné době nebude ustaven oficiální systém testování odrůd pro ekologické systémy hospodaření. Je proto nezbytné vytvořit jednoduchý metodický postup, který umožní otestování odrůd pšenice seté např. na úrovni farmy. Předkládaná metodika definuje ideotyp odrůdy pro ekologické zemědělství. Vlastní metodický postup je rozdělen na čtyři části: morfologické, biologické, hospodářské a jakostní znaky.

Quantitative genetic studies on breeding maize for adaptation to organic farming
Provedor de dados: 21
Autores: Burger, H.; Schloen, M.; Schmidt, W.; Geiger, H. H.
Organic farming has gained in importance in Germany during recent years.Therefore an increasing demand exists for varieties with specific adaptation to this farming system. In the present study we therefore conducted comparative field experiments with modern maize breeding materials under organic versus conventional farming conditions (ORGandCON, respectively) to estimate quantitative genetic parameters needed for developing optimal breeding strategies and to investigate the perspectives of selection for specific adaptation to ORG. Starting from two broad samples of elite germplasm, consisting of 178 flint and dent lines, respectively, fractions of 11 flint and 11 dent lines were selected based on their testcross performance under ORG. A corresponding set...

Genetic variability is the fundament of life. Large genetic variability within species is the basis for adaptation to changing environmental conditions. Farmers and breeders have developed a multitude of crop cultivars and animal breeds to stabilize and increase quality and productivity. This study evaluated genetic diversity within different organic and non-organic farming systems using crop-cultivar and livestock-breed information as simple indicators. Data was collected using on-farm surveys in 15 case study regions in Europe and beyond. Selected indicators revealed strong differences of cultivar diversity between different countries and farming systems across Europe. No or only small differences were detectable between organic and non-organic farming...

Evaluation of Laying Hen Strains for biodynamic Farms
Provedor de dados: 21
Autores: Zeltner, Esther.
In biodynamic and organic agriculture mostly the same strains of laying hens as in conventional agriculture are used. These strains require feed with a high nutrition level to tap the full potential of their genetic. When this feed is not available it may lead to health problems and ethological interferences as well as to a deficiency of performance. In this study, four potential adequate strains are evaluated and compared with a commercial strain using health and ethological parameters as well as characteristics of performance under biodynamic conditions. After one laying period the laying performance of Amberlik, Hyline, Sperber and Sussex was high but only the plumage condition of Sussex was acceptable. Therefore this strain will be used for further...

Drought Tolerance of Land Races of Emmer Wheat in Comparison to Soft Wheat
Provedor de dados: 21
Autores: Konvalina, Petr; Moudry, Jan; Dotlacil, Ladislav; Stehno, Zdenek; Moudry, Jan (Jr.).
As water deficiency becomes a more frequent cause of the reduction in wheat yield levels, the search for donors of drought tolerance to be bred into adapted land races becomes urgent. Drought tolerance has been evaluated by the 13C discrimination method in six land races of emmer wheat (Triticum dicoccum SCHRANK), compared with land races, obsolete cultivars and modern varieties of soft wheat (Triticum aestivum L.). The results of a two-year trial show that most of the genetic resources of emmer wheat, and intermediate land races of wheat are predisposed to drought tolerance. These varieties respond to dry conditions more sensitively, as they close their pores earlier (a lower value of the discrimination of 13C isotope). As for other land races and the top...

Workshop and desk study to appraise technical difficulties associated with organic breeder flocks and organic hatching
Provedor de dados: 21
Autores: Gordon, S.
BACKGROUND    To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally produced day old chicks up to three days of age to be brought into systems of organic table chicken production.  Chicks must be reared according to the rules laid down in Regulation (EC) 1804/1999 and according to UKROFS Standards for at least 70 days before the birds may be sold as being organic.  The derogation for organic breeder flocks was agreed for a transitional period expiring on 31st December 2003.  An extension to the derogation is being discussed at EU level (Article 14 Committee) but, as an interim measure, a new end date has not yet been published in the Official Journal.

Molecular markers to exploit genotype-environment interactions of relevance in organic growing systems
Provedor de dados: 21
Autores: Backes, Gunter; Østergard, Hanne.
One of the substantial differences between conventional and organic growing systems is the degree to which the farmer can control biotic and abiotic stresses; for organic growing systems varieties are needed with a broad adaptation to annually varying factors, while at the same time a good specific adaptation is necessary with respect to more constant climate and soil conditions. This combination of requirements implies that varieties for organic farming need to be better characterised with respect to genotype x environment interactions than varieties for conventional farming. Such interactions, which often are found for quantitatively expressed traits, are in general difficult to deal with in phenotypic selection. New approaches for QTL analyses (e.g....

Fair seed as a basis for organic products: Eosta takes a stand and supports the breeding of open-pollinated varieties.
Provedor de dados: 21
Autores: Janmaat, Leen; Nuijten, E.; Lammerts van Bueren, E.T.
Seed is the basis of food crops, and thus for products in shops, and comes with a long history. Plant breeding is developing rapidly, a fact that raises questions among growers, shopkeepers and consumers. In 2015, for the first time European patents were granted to companies for plant varieties and native plant traits, such as for a tomato variety with more healthy substances and a bell pepper variety that is resistant to pest insects. These patents have caused strong social indignation: the free exchange of seeds and plant material with these advantageous qualities is blocked by these patents. As a chain party, at Eosta we are taking a stand against this and support the free breeding in line with the values of organic agriculture as well as our products....

„Weiße Braunleger“ – Sind diese neuen TMA-toleranten Legehennen-Hybriden für den Ökolandbau geeignet?
Provedor de dados: 21
Autores: Rahmann, Gerold; Holle, Romana.
Rape cake can be a good source of high protein for laying hens. Consumers in Ger-many prefer brown organic eggs and pay a higher price than for white eggs. Brown eggs are produced from hybrids which can have a genetic deficit for digesting Sinap-ine – a glucosinolate in rape cake - and produce “fish-eggs”. Rape cake has to be treated at a high temperature to destroy the glucosinolate, but this treatment is expen-sive. A new hybrid hen– Lohmann Silver TMAfrei – has no genetic deficit and still produces brown eggs. In a feeding experiment in 2004 and 2005, this hybrid showed comparable production and performance results to TETRA SL (typical organic hybrid) and LSL (white egg producer). The breed is suitable for use should feed stuffs with high glucosinolate...

Breeding of resistant strawberry cultivars for organic fruit production – Diallel crossing strategies and resistance tests for Botrytis cinerea and Xanthomonas fragariae
Provedor de dados: 21
Autores: Bestfleisch, M.; Höfer, M.; Richter, K.; Hanke, M.-V.; Schulte, E.; Peil, A.; Flachowsky, H.
Organic strawberry production suffers from high yield losses caused by numerous fungal and bacterial diseases. Two of the most important diseases are the grey mould disease caused by Botrytis cinerea Pers. (teleomorph Botryotinia fuckeliana), and the bacterial angular leaf spot disease caused by Xanthomonas fragariae (Kennedy &amp; King). Beside cultivation methods and organic plant protection measures, the development of resistant cultivars seems to be the most promising strategy in order to improve the productivity in organic strawberry cultivation. Therefore, we established resistance tests to determine resistant and susceptible strawberry cultivars and breeding selections. In a first run, 40 different cultivars and selections were tested for their...

Robust breeds for organic pig production
Provedor de dados: 21
Autores: Serup, T.
Robust animals – here piglets – are important for the organic production, since vital and healthy animals are one of the pillars for animal welfare and comfort in the daily manage-ment. One of the key issues in the conventional breeding system is a high litter size. The average is 15 – 16 live born, but quite often more than 20 piglets are seen in practice. The organic production system uses the same genetic as the conventional because the production scale is too small to run its own breeding system.  The organic regulation offers a frame for a wide range of high level of animal welfare pa-rameters (free range, prolonged nursing period and access to roughage, just to mention some). However, at the same time it has to face a major problem with high...

Empfehlungen  Die Sorten Passion und Soraya waren im 2017 das zweite und somit das letzte Jahr in den Testversuchen. Trotz der guten Blattgesundheit, der hohen Krautfäule-Resistenz und dem enormen Ertragspotential der Sorte Passion, kann eine Aufnahme auf die Bio-Sortenliste nicht empfohlen werden. Einerseits führt die helle Schale und Fleischfarbe dazu, dass Mängel herausstechen (Schorf, Pocken, Drycore) und andererseits ist auch der Geschmack nicht überzeugend. Zudem sind die Knollen sehr grossfallend, wodurch ein grosser Anteil der Produktion aussortiert werden muss.    Soraya hat in beiden Jahren stabile Erträge und keine gravierenden Mängel gezeigt. Auch im Geschmack und in der Fleischfarbe ist die Sorte gut. Bezüglich Krautfäule-Toleranz ist Soraya...

Zweinutzungshühner als Alternative zur Tötung von  Eintagsküken
Provedor de dados: 21
Autores: Schmidt, Eggert; Damme, Klaus.
The culling of day-old male layer chicks is a constant issue in the animal welfare discussion. The dual purpose chicken is an alternative. In this test cockerels from dual  purpose breeds were compared to fast and slow growing chicken. An additional fattening period of at least two weeks is necessary to achieve the final weight of 2.3  kg. Due to a decline in feed conversion approximately 20% additional feed energy is necessary to produce 1 kg lean meat. The laying performance reached an acceptable  number of 260 eggs per year. An insufficient egg weight is the reason for a higher amount of S-grade eggs. Again 20% additional feed energy per kg egg mass is necessary compared to specialized breeds.

Apricot susceptibility to blossom brown rot (Monilinia spp.) and leaf rust (Tranzschelia spp.) under low-input production system
Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Broquaire, Jean-Michel; Mercier, Vincent; Gomez, Christelle; Brun, Laurent; Clauzel, Guy; Guillermin, Armand; Audergon, Jean-Marc.
Production regularity in organic apricot orchards is highly constrained by blossom brown rot caused by Monilinia spp. infections on flowers. Leaf rust (Tranzschelia spp.) development can induce early defoliation, which is detrimental to tree vigour and yield. Copper-based treatments are partially efficient against both diseases but their negative environmental impact should be considered. The choice of cultivars according to disease susceptibility criterions is a key-step towards low-input production systems.  This poster presents the susceptibilities to blossom brown rot and leaf rust of 16 apricot cultivars observed during 5 years in two sites.

L'évaluation des nouvelles variétés fait partie du programme de recherche du FiBL. Elle se fait dans le cadre d'essais précis et aussi chez les producteurs. A Frick les essais se font en conditions "extrêmes", c'est à dire sans traitement contre les pucerons, sans éclaircissage et sur les arbres plus âgés, sans traitement contre l'oïdium et la suie. Ces conditions permettent d'apprécier les nouvelles variétés dans l'environnement difficiles de la production bio. Les remarques des praticiens sont les bienvenues!

Consumer Reaction to the «Flavour Group Concept» to introduce Scab Resistant Apple Varieties into the Market. «Variety-Teams» as a Further Development of the Concept
Provedor de dados: 21
Autores: Weibel, Franco; Leder, Alfred.
A tool to ease the market introduction of scab resistant apple varieties in supermarkets, is the so-called «Flavour Group Concept (FGC; Weibel and Grab, 2000) that has been developed by FiBL and «Coop» (second biggest supermarket retailer of Switzerland) already in 1995. The FGC is providing to the buyers additional information on the specific flavour direction of that "unknown" apple cultivar in front of them (mild to sweet; spicy-tart; predominantly tart). In 2002 a consumer behaviour study was undertaken by «IHA/GfK-Switzerland» Institute to evaluate the consumer response to the FGC.   The results reveal that 36 % of the persons interviewed at the point of sale considered additional information on the flavour direction of the apple cultivars as...

Landraces and Obsolete Cultivars of Minor Wheat Species in the Czech Collection of Wheat Genetic Resources
Provedor de dados: 21
Autores: Stehno, Zdenek; Bradova, J.; Dotlacil, Ladislav; Konvalina, Petr.
Proportion of landraces in the Czech collection of wheat genetic resources differentiates deeply among wheat species, 4.2 % in bread, 77.6 % in emmer and 80.0 % in einkorn wheat collection. The set of 10 selected emmer wheat landraces has been characterised by high molecular weight glutenin subunits (HMW-GSs), evaluated for 3 years in field trials and described by grain quality parameters. Emmer wheat accessions distinguished considerably in polymorphisms of HMW-GSs. Out of the total number of 10 studied emmer wheat landraces 5 accessions appeared to be homogeneous in the electrophoretic patterns of HMW-GSs and they were formed by a single glutenin line. Much higher crude protein content in comparison with check bread wheat cultivar was detected in all...

PROJECT: Green Crop Lifting – an Alternative Producing Healthy Seed Potatoes in the System of Organic Farming
Provedor de dados: 21
Autores: Böhm, H.; Fittje, S.
The standards of organic farming require the use of organically grown seeds in organic potato farming. Presumably the use of conventionally grown seeds under exceptional circumstances will end in 2003. Only organically grown seeds can be used thereafter. Therefore, it is important to check alternatives for organic potato seed production, which will reduce the cultivation risk, guarantee a high quality of seed potatoes (virus-free and healthy seed), and increase the fraction of marketable potatoes. On 7 farms in Northern Germany (4 sites in the coastal region (Schleswig-Holstein) and 3 sites in the inland region (Lower Saxony)) the green crop lifting (GCL) at two different dates was checked against the traditional process (haulm cutting) and a control plot...

Anpassung der regionalisierten Versuchsauswertung mit überlappenden Anbaugebieten für Sortenversuche im ökologischen Landbau
Provedor de dados: 21
Autores: Gruber, Harriet; Zenk, Andrea.
Der in den meisten Bundesländern eingeschränkte Umfang an Sortenversuchen im ökologi-schen Landbau erschwert eine regionale Sortenempfehlung. Die vielfach geringere Ver-suchspräzision in diesen Anbausystemen verschärft das Problem, welches in häufig hohen Standardfehlern und großen Grenzdifferenzen seinen Ausdruck findet. Daher war es erforderlich auch für die Auswertung der Sortenversuche im ökologischen Landbau Anbaugebiete zu bilden und eine überregionale Auswertung unter Einbeziehung der Ergebnisse benachbarter Anbaugebiete vorzunehmen. Ein weiterer Schritt war die Einführung der Hohenheim-Gülzower Serienauswertung.

Apples are the most prominent fruits produced in Europe. However, their organic production is very challenging and most cultivars can only be produced economically with copper application to combat fungal diseases. Therefore, the existing cultivars need to be replaced by more resilient genotypes also considering improvement of the rootstocks for better adaptation to organic soil, fertility conditions and new diseases. The objective of LIVESEED Horizon 2020 project is to improve the performance and sustainability of organic agriculture by  boosting organic seed and plant breeding efforts, and increasing the availability of cultivars adapted to organic growing conditions.

Suitable conservation strategies for endangered domesticated breeds hinge on the knowledge of their special traits and benefits. We compared the performance of en-dangered geese and turkey breeds with common hybrid breeds, and focussed on meat quality as a potential marketing factor for a cost efficient on-farm conservation strategy. The animals were reared under identical feeding and housing conditions. In comparison with the endangered breeds, the hybrid breeds of both species were heavier and showed a lower feed conversion ratio. The meat of the endangered goose breed showed a higher drip loss, while the meat of the endangered turkey breed had less cooking loss, a higher shear force, and was preferred in a sensory test.

Applications of crop competitive ability in winter oats (Avena sativa L.)
Provedor de dados: 21
Autores: Fradgley, Nick; Creissen, Henry; Sally, Howlett; Helen, Pearce; Robbie, Girling.
Crop competition is a key component of an integrated approach to weed management.  Variation in competitive ability and competitive traits have been identified in many other crop species, however little work has been done on oats.    Trials were carried out over four years at one organic site with five husked and three naked oat varieties.  Mid-season Leaf Area Index (LAI) and tillering ability were identified as weed suppressive traits using path analysis.  Differences in weed tolerance were found among varieties.  Trade-offs may exist between competitive traits and yield potential which could be optimised by limiting competitive traits later in the season.  Selection of competitive traits with high heritability, whilst minimising yield penalties, could...

Hulled wheat species (einkorn, emmer, spelt) are presumed to be an alternative to bread wheat in organic agriculture since the yield penalty is less pronounced under organic farming and generally higher prices can be achieved for specialty grains. The present study analyzed differences between wheat species with respect to biomass production, harvest index, grain yield and protein content. Spring hulled wheat genetic resources and bread wheat check cultivars were grown in organic field trials in the Czech Republic and Austria between 2010 and 2012. Generally, hulled wheat species were inferior in grain yield and distribution of assimilates to the grain compared to modern bread wheat. Biomass production of some emmer and spelt landraces was similar to bread...

Spannende Nischensorten für den Biokartoffelanbau
Provedor de dados: 21
Autores: Gelencsér, Tobias.
Direktvermarkter und Marktfahrer bauen meist viele Kulturen in kleinerem Umfang an, um ihren Kunden eine grössere Auswahl an Produkten anbieten zu können. Die Ansprüche an eine Kartoffelsorte sind deshalb anders als bei stark spezialisierten Betrieben.  Gefragt sind häufig Sorten, die einfacher in der Kulturführung sind oder Nischensorten, um sich besser vom Detailhandel abzuheben und seiner Kundschaft etwas Aussergewöhnliches anbieten zu können.

Genotypic differences in growth, yield and nutrient accumulation of spring wheat cultivars in response to long-term soil fertility regimes
Provedor de dados: 21
Autores: Wang, Yaosheng; Magid, Jakob; Thorup-Kristensen, Kristian; Stoumann Jensen, Lars.
Determining genotypic responses to soil fertility may assist selection of cultivars that can be adapted to varied soil fertility regimes, and such selection under field conditions is still limited. A two-year field experiment was conducted in long-term field trials to investigate wheat genotype effects on early growth, yield and nutrient accumulation as affected by varied long-term soil fertility managements and nitrogen (N) fertilization. Results show that the early growth, grain yield and nutrient accumulation of spring wheat plants were strongly affected by soil fertility managements and genotypes. Early shoot and root biomass of singly grown plants and leaf canopy growth under standard growth density was associated with subsequent grain yield of plants...

Provedor de dados: 21
Autores: Boie, Petra; Fleck, Michael.
Ausgangspunkt des Projektes war vor vier Jahren die durch z.B. das FIBL-Dossier „Pflanzenzüchtung“ unterstützte These, dass die Methoden der konventionellen Pflanzenzüchtung sich immer weiter von den Praktiken entfernen, die für den Ökologischen Landbau und die Biologisch-Dynamische Wirtschaftsweise geeignet angesehen werden. Die Kritik bezieht sich sowohl auf die angewandten Techniken als auch auf die Reduktion der Sorten auf bloßes Wirtschaftsgut. Unter dem Dach des Vereins Kultursaat werden Gemüsesorten entwickelt, die in qualitativer, sozio-ökonomischer und ethischer Hinsicht den Prinzipien des Ökologischen Landbaus entsprechen (z.B. Participatory Plant Breeding). Da die o.a. Lage sich mit zunehmender Ausbreitung der Gentechnik verschärft, bei allen...

Rassenvergelijking Regioras: Kostelijk Brabant 2013
Provedor de dados: 21
Autores: Nuijten, E.; Groenen, R.
Een belangrijke stap om kennis over zaadvermeerdering en veredeling onder telers in stand te houden is bewustzijn van raskenmerken te bevorderen, dat wil zeggen het bewustzijn dat niet alle rassen voor alle teeltsystemen geschikt zijn. Zo geldt dit met name voor biologische abonnemententelers in Brabant die op zandgrond werken. Groenteveredeling richt zich op grootschalige intensieve teelt op vruchtbare (klei) bodems. Deze rassen zijn steeds minder geschikt voor biologische abonnemententelers.  De opzet van dit project was om specifiek met deze Noord‐Brabantse telers van drie gewassen een rassenvergelijking op te zetten (veldsla, boerenkool en rode biet), per gewas vijf rassen, en de kwaliteit gezamenlijk te vergelijken.

Rationsgestaltung und Eignung unterschiedlicher Herkünfte für die ökologische Hähnchenmast
Provedor de dados: 21
Die ausschließliche Versorgung von Masthähnchen mit ökologisch erzeugten Futtermitteln erschwert die Rationsgestaltung erheblich. Probleme bereitet hierbei eine adäquate Aminosäurezusammensetzung der Futtermischung bzw. das Verhältnis von Energie zu essentiellen Aminosäuren. Ferner schreibt die Verordnung (EWG) Nr. 2092/1991 für die ökologische Hühnermast die Verwendung langsam wachsender Herkünfte oder ein Mindestschlachtalter von 81 Tagen vor. Als langsam wachsende Herkunft werden in Deutschland überwiegend Tiere des Hybridzuchtunternehmens ISA-Hubbard eingesetzt, obwohl andere Genotypen auch geeignet erscheinen. In einer Stationsprüfung sind zwei Fütterungsstrategien an insgesamt vier langsam wachsenden Herkünften in zwei Durchgängen zu testen. Je...

Autores: Abel, Hansjörg; Pawelzik, Elke; Breves, Gerd.
Es wurden Nährstoffanalysen an ökologisch und konventionell angebauten Weizen-, Gerste- und Ackerbohnensorten durchgeführt. Im Vergleich zum konventionellen Anbau führte der ökologische Anbau bei Weizen und Gerste zu niedrigeren Rohprotein- sowie höheren Stärke- und Fasergehalten. Bei Ackerbohnen ergaben sich tendenziell ähnliche Veränderungen, die Stärkegehalte wurden jedoch bei ökologischer Anbauweise gesenkt.  In Stoffwechselversuchen wurden „Schwäbisch Hällische“ (SH), „Bunte Bentheimer“ (BB) und moderne Gebrauchskreuzungsschweine (CB) mit jeweils einer Grundration und einer Zulageration (+Zuckerrübentrockenschnitzel) versorgt.

Plant breeding with farmers. A technical manual
Provedor de dados: 21
Autores: Ceccarelli, Salvatore.
Participatory plant breeding (PPB) is defined as a type of plant breeding in which farmers, as well as other partners, such as extension staff, seed producers, traders and NGOs, participate in the development of a new variety. In PPB programs farmers play a more important role than in conventional plant breeding (CPB). Both PPB and CPB are based on the same scientific background and are not mutually exclusive. This tool describes how to organize a PPB programme in self-pollinated, cross-pollinated and vegetatively propagated crops, how to design the trials, collect, organize and analyse the data, and eventually how to use and share the information generated by a PPB. The manual is addressed to all those involved in planning and implementing participatory...

Tolerance of competitive spring barley cultivars to weed harrowing
Provedor de dados: 21
Autores: Rasmussen, Jesper; Kurtzmann, J.I.; Jensen, A.
Two experiments were conducted in 14 spring barley cultivars to investigate if crop tolerance to post-emergence weed harrowing is related to morphological traits that reflect competitiveness. The experiments were carried out in organically grown fields where low weed densities and biomass production were assumed to be without significant influence on crop growth. The experiments showed that different cultivars responded differently to post-emergence weed harrowing in terms of yield reduction. Taller and higher yielding cultivars with high LAIs tended to be less tolerant to post-emergence weed harrowing than shorter and lower yielding cultivars with low LAIs. This conclusion, however, is only valid for 13 out of 14 cultivars because one very tall cultivar...

One of the keystones of the organic orchard is the cultivar choice as one element of pest and disease control. However, few exhaustive data sets concerning the cultivar susceptibility to pests and diseases are available for growers. In order to identify cultivars adapted to organic production methods, the susceptibility to scab, aphids and powdery mildew and the agronomic properties of 36 cultivars were assessed in four French sites under different pedo-climatic conditions. Different levels of susceptibility to scab were observed for 23 scab Vf-resistant and 13 other cultivars. In the North of France where Vf resistance is overcome, the Vf cultivars displayed different levels of scab severity. A high variability in the susceptibility to aphids was observed...

Applications of crop competitive ability in winter oats (Avena sativa L.)
Provedor de dados: 21
Autores: Fradgley, Nick; Creissen, Henry; Howlett, Sally; Pearce, Helen; Girling, Robbie.
Crop competition is a key component of an integrated approach to weed management.  Variation in competitive ability and competitive traits have been identified in many other crop species, however little work has been done on oats.    Trials were carried out over four years at one organic site with five husked and three naked oat varieties.  Mid-season Leaf Area Index (LAI) and tillering ability were identified as weed suppressive traits using path analysis.  Differences in weed tolerance were found among varieties.  Trade-offs may exist between competitive traits and yield potential which could be optimised by limiting competitive traits later in the season.  Selection of competitive traits with high heritability, whilst minimising yield penalties, could...

Since 1960 the majority of commercial layers are housed in cages. Non-cage housing started to appear again from 1980 onwards and increases in importance. It is questionable if birds bred to perform in cages are also suited for free range housing. We examined the performance of current genotypes in free range systems (organic and conventional) by an inventory among laying hen farmers in Switzerland, The Netherlands and France (325 flocks on 275 farms) and organised workshops with farmers to discuss their ideas on breeding goals (‘the ideal hen’) for free range systems.

Reproductive behavior of the Red-crested Finch Coryphospingus cucullatus (Aves: Thraupidae) in southeastern Brazil
Provedor de dados: 103
Autores: Zima,Paulo V.Q.; Francisco,Mercival R.
ABSTRACT Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests. This information may be valuable to elucidate the phylogenetic relationships of this bird, and to design plans to manage it. Nesting activities occurred from October to February. Clutches consisted of two to three eggs (2.06 ± 0.25), which were laid on consecutive days. Incubation usually started the morning the females laid their last egg and lasted 11.27 ± 0.47 days. Hatching was synchronous, or happened at a one-day interval. The nestling stage lasted 12 ± 0.89 days. Only females incubated the eggs and they fed the young more often than the males did. Overall...

This study aimed to estimate the energy requirements for maintenance and gain of Japanese and European quails under growth housed in two rearing systems: floor pens and cages. To determine maintenance requirements, two experiments were conducted with birds housed in cages in environmental chambers (experiment 1) and in floor pens at room temperature conditions (experiment 2). The experimental design was completely randomized with four levels of feed supply (100, 75, 50 and 25%) and four repetitions. Energy requirements for maintenance were estimated by the comparative slaughter method through a feeding trial. In experiment 1, 64 Japanese and European quails per treatment were housed in cages of climatic chambers at 18, 24, and 28 °C, while in experiment 2,...

Phenotypic recurrent selection to improve protein quality in non-opaque maize populations
Provedor de dados: 63
Autores: Garcia,Antonio Augusto Franco; Souza Jr.,Cláudio Lopes de.
Maize (Zea mays L.) protein is considered to be of low quality due to low levels of the essential lysine and tryptophan amino acids. An alternative to solve this problem is to use the opaque-2 gene, which improves the level of these amino acids, but has negative pleiotropic effects on agronomic characters. A phenotypic recurrent selection scheme was carried out in two non-opaque maize populations to verify the possibility of improving their protein quality without using this gene. Four cycles were completed and a 20% selection intensity for tryptophan content in the kernels was used in two populations, IG-1 and IG-2. The original and the four-cycle populations were evaluated in three locations for agronomic traits. For protein and tryptophan content, a...

Autores: Oviedo,Victoria Rossmary Santacruz; Godoy,Amanda Regina; Cardoso,Antonio Ismael Inácio.
Inbreeding reduces the vigor in plants as a result of a decrease in the proportion of heterozygous loci. However, the influence of inbreeding is different among the species. The objective of this work was to evaluate the inbreeding depression in a cucumber Japanese population. An F2 population was obtained from a commercial hybrid (Natsu suzumi), which was considered as S0 population. S1, S2, S3, S4 and S5 progenies were obtained by the 'Single Seed Descent' methodology. A complete blocks design with seven treatments (different generations of self pollination - S0 to S5 and the hybrid Natsu suzumi), and six replications of five plants per plot was used in protected cultivation from Aug. 21 to Nov. 29, 2002.

Broiler meat quality is one of the primary factors considered by the poultry industry. This study was conducted to estimate heritability and genetic correlation coefficients for meat quality traits in a single male broiler line. The meat ultimate pH (24 h after slaughter) and lightness presented the highest heritability estimates. Given the estimated genetic correlations, the pH measured at 15 min and 24 h after slaughtering, as well as lightness, were characterized by a close and negative genetic relationship with water holding capacity traits. In contrast, meat quality traits exhibited only non-significant genetic correlations with performance and carcass traits. Noticed exceptions were breast weight, which was genetically and favorably associated with...

It is possible to produce onions (Allium cepa) all over the year in Brazil, but most of the Brazilian cultivars have poor quality bulbs, a fact that favours onion imports from Argentina, a producer of Valenciana type cultivars that does not bulb in Brazil, but please Brazilian consumers. To study the effect of selection for bulb maturity, seventeen half sib progenies selected for early maturity and twenty five for late maturity, from the intervarietal triple cross [Crioula x (Pira Ouro x Valenciana Sintetica 14)] were grown, along with the triple cross itself and the cultivars Pira Ouro (short-day), Crioula (intermediate-day) and Armada (long-day). A total of forty six treatments were tested in a randomized block design with three replications of 32 plants...

Autores: Fuzinatto,Veridiana Aparecida; Pagliarini,Maria Suely; Valle,Cacilda Borges do.
Hybrids combining desirable traits from divergent parents are the main objective of some Brachiaria (Syn. Urochloa P. Beauv.) breeding programs. There is great interest in the development of apomictic hybrid cultivars that combine desirable genes such as resistance to spittlebugs, high nutritive value, and tolerance to acid soils. Microsporogenesis of six apomictic progenies resulting from a tetraploid (2n = 4x = 36) cross between B. ruziziensis × B. brizantha was evaluated under light microscopy. Genetic recombination, ensured by multivalent chromosome association and crossing-over at prophase occurred in low frequency among progenies, and in one, recombination was almost nonexistent. The percentage of meiocytes with meiotic abnormalities among progenies...

Root-knot nematodes (Meloidogyne spp.) are an important worldwide pest of cucumber (Cucumis sativus L.). Molecular markers linked to the Javanese root-knot nematode (M. javanica) resistance gene mj in cucumber may aid marker assisted selection. One-hundred AFLP (EcoRI-MseI) and 112 SRAP were used to screen resistant and susceptible parents for polymorphisms to develop molecular markers linked to the mj gene. Of the 100 AFLP primers, 92 produced bands and two yielded candidate markers (E-ATT/M-CAA and E-AAC/M-CTG). These two bands were cut off from polyacrylamide gel, cloned and sequenced. Primers designed from the sequences did not yield polymorphic bands between the parents. In addition, the sequences did not contain any restriction site or indel to be...

Recent technological advancements have substantially expanded our ability to analyze and understand plant genomes and to reduce the gap existing between genotype and phenotype. The fast evolving field of genomics allows scientists to analyze thousand of genes in parallel, to understand the genetic architecture of plant genomes and also to isolate the genes responsible for mutations. Furthermore, whole genomes can now be sequenced. This review addresses these issues and also discusses ways to extract biological meaning from DNA data. Although genomic issuesare addressed from a plant perspective, this review provides insights into the genomic analyses of other organisms

ABSTRACT: The research intends to detect sources of contamination by Yersinia enterocolitica in the abattoir flowchart and endeavors to study its relation with the contamination in the farm. For this purpose, sixty pigs were followed up. In order to carry out the study, samples of faeces were collected from the animal farm, where the animals were originally kept and from the abattoir, directly from the animal’s rectum, after desensitization. Additionally, samples were also collected from the carcass, after passage into the hair removal machine, after evisceration, prior to entry into the cold chambre, from the jowls, and water of the scald tank, before the commencement of the abattoir as well as after the passage of the animals. Further, the isolates were...

Orthophytum grossiorum is a typical bromeliad from Atlantic forestry threatened of extinction. The objectives of this research were to select O. grossiorum clones with ornamental values easy to propagate in vitro, and establish in vitro propagation protocols for these clones. The project was developed in three steps: germination and in vitro selection of seedlings responsive to BAP (6-benzylaminopurine), selection of clones with ornamental values, and establishment of protocol for in vitro propagation of the selected clones. In the first step only 18.33% of plantlets germinated in vitro were responsive to BAP. These plantlets were selected and replicated in vitro several times, each replicated plantlet constituting a clone. In the second step these clones...

Selection in several environments by BLP as an alternative to pooled anova in crop breeding
Provedor de dados: 64
Autores: Bueno Filho,Júlio Sílvio de Sousa; Vencovsky,Roland.
Plant breeders often carry out genetic trials in balanced designs. That is not always the case with animal genetic trials. In plant breeding is usual to select progenies tested in several environments by pooled analysis of variance (ANOVA). This procedure is based on the global averages for each family, although genetic values of progenies are better viewed as random effects. Thus, the appropriate form of analysis is more likely to follow the mixed models approach to progeny tests, which became a common practice in animal breeding. Best Linear Unbiased Prediction (BLUP) is not a "method" but a feature of mixed model estimators (predictors) of random effects and may be derived in so many ways that it has the potential of unifying the statistical theory of...

Provedor de dados: 69
Autores: Vanzetti,Leonardo Sebastián; Campos,Pablo; Demichelis,Melina; Lombardo,Lucio Andres; Aurelia,Paola Romina; Vaschetto,Luis María; Bainotti,Carlos Tomás; Helguera,Marcelo.
Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat (Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method of controlling the disease. Gene postulation helps to determine leaf rust resistance genes (Lr genes) that may be present in a large group of wheat germplasm. Additionally presence of Lr genes can be determined using associated molecular markers. The objective of this study was to identify Lr genes that condition leaf rust resistance in 66 wheat cultivars from Argentina. Twenty four differential lines with individual known leaf rust resistance genes were tested with 17 different pathotypes of leaf rust collected from Argentina. Leaf rust...

Ecological setup, ploidy diversity, and reproductive biology of Paspalum modestum, a promising wetland forage grass from South America
Provedor de dados: 74
Autores: Karunarathne,Piyal; Feduzka,Cristian; Diego,Hojsgaard.
Abstract With ever-rising demand for food, forage breeding for intensification of cattle production is also taking a leap. In South America, cattle production systems are displaced to marginal areas poorly exploited with cultivated pastures yet with high potential for growing stocking rates. This places the need for using native genetic resources to breed locally adapted plant genotypes that benefits from better forage quality, yield, and lesser threat to the local biodiversity. Paspalum modestum Mez is a grass species that produces quality forage and grows in marginal areas like estuaries and floodplains, suitable for introduction in breeding programs. In this study we characterize the species' reproductive biology and ecological preferences needed...

Expression profiles of sugarcane under drought conditions: Variation in gene regulation
Provedor de dados: 74
Autores: Andrade,Júlio César Farias de; Terto,Jackeline; Silva,José Vieira; Almeida,Cícero.
Abstract Drought is a major factor in decreased sugarcane productivity because of the resulting morphophysiological effects that it causes. Gene expression studies that have examined the influence of water stress in sugarcane have yielded divergent results, indicating the absence of a fixed pattern of changes in gene expression. In this work, we investigated the expression profiles of 12 genes in the leaves of a drought-tolerant genotype (RB72910) of sugarcane and compared the results with those of other studies. The genotype was subjected to 80–100% water availability (control condition) and 0–20% water availability (simulated drought). To analyze the physiological status, the SPAD index, Fv/Fm ratio, net photosynthesis (A), stomatal conductance (gs) and...

Reciprocal recurrent selection effects on the genetic structure of tropical maize populations assessed at microsatellite loci
Provedor de dados: 74
Autores: Pinto,Luciana Rossini; Vieira,Maria Lucia Carneiro; Souza Jr.,Claudio Lopes de; Souza,Anete Pereira de.
A modified reciprocal recurrent selection (RRS) method, which employed one cycle of high-intensity selection, was applied to two tropical maize (Zea mays L.) populations, BR-105 and BR-106, originating the improved synthetics IG-3 and IG-4, respectively. In the present study the effects of this kind of selection on the genetic structure of these populations and their synthetics were investigated at 30 microsatellite (SSR) loci. A total of 125 alleles were revealed. A reduction in the number of alleles was observed after selection, as well as changes in allele frequencies. In nearly 13% (BR-105) and 7% (BR-106) of the loci evaluated, the changes in allele frequencies were not explained, exclusively due to the effects of genetic drift. The effective...

Detection of self-incompatible oilseed rape plants (Brassica napus L.) based on molecular markers for identification of the class I S haplotype
Provedor de dados: 74
Autores: Havlícková,Lenka; Jozová,Eva; Klíma,Miroslav; Kucera,Vratislav; Curn,Vladislav.
The selection of desirable genotypes with recessive characteristics, such as self-incompatible plants, is often difficult or even impossible and represents a crucial barrier in accelerating the breeding process. Molecular approaches and selection based on molecular markers can allow breeders to overcome this limitation. The use of self-incompatibility is an alternative in hybrid breeding of oilseed rape. Unfortunately, stable self-incompatibility is recessive and phenotype-based selection is very difficult and time-consuming. The development of reliable molecular markers for detecting desirable plants with functional self-incompatible genes is of great importance for breeders and allows selection at early stages of plant growth. Because most of these...

Inclusion of genetic relationship information in the pedigree selection method using mixed models
Provedor de dados: 74
Autores: Nunes,José Airton Rodrigues; Ramalho,Magno Antonio Patto; Ferreira,Daniel Furtado.
We used a mixed model approach and computer simulation to evaluate the inclusion of parentage information as determined by the genealogy established in the pedigree method. The simulations were based on a purely additive genetic model for one quantitative trait of 20 unlinked segregating loci with equal effects and an allelic frequency of 0.5 for heritability values of 10%, 25%, 50% and 75% for selection based on an F4:5 progeny mean. We simulated 1000 experiments for each heritability value, corresponding to the evaluation of 256 F4:5 progenies. The phenotypic values of the progenies were analyzed according to two models, one ignoring and one considering the additive genetic parentage among the progenies. The additive relationship coefficients among F4:5...

Dominance, epistasis, heritabilities and expected genetic gains
Provedor de dados: 74
Autores: Viana,José Marcelo Soriano.
Although epistasis is common in gene systems that determine quantitative traits, it is usually not possible to estimate the epistatic components of genotypic variance because experiments in breeding programs include only one type of progeny. As the study of this phenomenon is complex, there is a lack of theoretical knowledge on the contribution of the epistatic variances when predicting gains from selection and on the bias in estimating genetic parameters when fitting the additive-dominant model. The objective of this paper is to discuss these aspects. Regarding a non-inbred population, the genetic value due to dominance and the epistatic components of the genotypic value are not indicators of the number of favorable genes present in an individual. Thus,...

Partitioning genetic effects due to embryo, cytoplasm and maternal parent for oil content in oilseed rape (Brassica napus L.)
Provedor de dados: 74
Autores: Wu,Jian-Guo; Shi,Chun-Hai; Zhang,Hai-Zhen.
Analysis of genetic main effects and genotype x environment (GE) interaction effects on the oil content of oilseed rape (Brassica napus L.) was conducted by using a genetic model for the quantitative traits of seeds in diploid plants. The experiments were carried out over two years with 8 parents and a diallel mating design, which produced F1 and F2 generations. We found that the oil content of rape was simultaneously controlled by embryo genetic effect, cytoplasmic effects and maternal genetic effect as well as GE interaction effects, with the cytoplasmic and maternal effects playing the main role. The results indicate that selection of maternal plants for high oil content would be more efficient than selection based on single seeds. Since the GE...

In this study, the breeding perspectives of 41 open-pollinated progenies of Eucalyptus grandis were evaluated based on their wood traits. The progenies were distributed in two experiments in a randomized complete block design, with three replicates and linear plots containing six plants each. The traits were assessed at eight years of age. Two trees from each plot were selected for this assessment based on better growth, stem form and phytosanity. Significant differences in basic density, sapwood/heartwood ratio, bowing, specific gravity, parallel compression and static bending were detected among the progenies. These traits were potentially promising for breeding programs, with heritability coefficients that varied from 0.34 to 0.61 on a progeny mean...

Parentage testing and effect of misidentification on the estimation of breeding value in Gir cattle
Provedor de dados: 74
Autores: Baron,Erica E.; Martinez,Mário L.; Verneque,Rui S.; Coutinho,Luiz L.
A correct relationship among sires is essential for an efficient breeding program. Microsatellite markers were used in progeny tests, to assess the paternity of seventy-four probable offspring of nine Gir dairy sires. A 36% misidentification rate was observed; however, these errors had minimal effects on the ranking of the nine bulls with regard to their genetic values. The results suggest that paternity tests should be performed in breeding programs, in order to prevent inappropriate paternities from influencing the genetic value of bulls in the future.

Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic divergence among eight Coffea species and to identify the parentage of six interspecific hybrids. A total of 14 primers which contained different simple sequence repeats (SSR) were used as single primers or combined in pairs and tested for PCR amplifications. Two hundred and thirty highly reproducible fragments were amplified, which were then used to estimate the genetic similarity and to cluster the Coffea species and hybrids. High levels of interspecific genetic variation were revealed.

The study of inbreeding depression is important for breeding strategies such as use of inbred progenies or extraction of inbreed lines. A diallel of 28 maize open-pollinated varieties was evaluated in 10 environments in the early 1990s. At the same time, S1 populations for each of the 28 varieties were evaluated in the same 10 experiments (environments). Yield reductions of the populations from S0 to S1 (mean of the 10 environments), varied from 34.6% (CMS-01) to 59.2% (CMS-30), with an average of 49.1%. Inbreeding depression was greater in populations with a wider genetic base, which had never been exposed to inbreeding (CMS-30, BR-107, PH4, Cunha, Saracura, Nitrodent, and Nitroflint). Inbred lines with greater yield means should be obtained from the...

Autores: Guimarães,Lúcio Mauro da Silva; Resende,Marcos Deon Vilela de; Lau,Douglas; Rosse,Leonardo Novaes; Alves,Alexandre Alonso; Alfenas,Acelino Couto.
Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil. The wide inter and intra-specific genetic variability of resistance to canker among Eucalyptus species facilitates the selection of resistant plants. In this study, we evaluated resistance to this pathogen in five Eucalyptus grandis (G) and 15 E. urophylla (U) trees, as well as in 495 individuals from 27 progenies derived from crosses between the trees. In the field, six-months-old test seedlings were inoculated with C. cubensis. Lesion length in the xylem and bark was measured eight months later. The results...

BRS Juruti: the first Brazilian habanero-type hot pepper cultivar
Provedor de dados: 75
Autores: Ribeiro,Claudia SC; Souza,Karina RR; Carvalho,Sabrina IC; Reifschneider,Francisco JB.
ABSTRACT: The Habanero hot pepper group is not well known in Brazil, despite its origin in the Amazon. Nevertheless, domestic and international markets have been increasing the demand for this type of hot pepper. The Brazilian agroindustry is interested in supplying part of this demand with high quality products and competitive prices, and it needs well-adapted cultivars. To fill this gap, Embrapa Vegetables developed the Habanero pepper cultivar BRS Juruti, which meets the demands of both the market for fresh fruit and the processing agroindustry of mash and sauces. Cultivar BRS Juruti has red fruits and yielded around 50 t/ha (36,000 plants/ha). Fruit pungency is circa 260,000 SHU and fruits have high content of vitamin C (122 mg/100 g). BRS Juruti is...

ABSTRACT The objective of this study was to evaluate stigma receptivity and anther dehiscence in three floral development stages in F3 population of ornamental pepper (Capsicum annuum). A total of 162 plants (81 of purple corolla and 81 of white corolla) were used in this study. To analyze the stigma receptivity and anther dehiscence, three floral stages were analyzed: bud, pre-anthesis, and open flower. For each stage, 33 flowers of each phenotypic class were collected. The receptivity of the stigma was detected by dripping hydrogen peroxide solution (3%). For the evaluation of the level of receptivity, scores of 0 to 3 were assigned, varying according to the bubbles percentage found on the stigmatic surface. Scores of 1 to 5 were assigned for the...

Repeatability of agronomic and morphological characteristics in ornamental pepper
Provedor de dados: 75
Autores: Ribeiro,Wellington S; Costa,Lucas C; Dias,Fabíola S; Silva,Francisco CS; Pinto,Cleide MF; Finger,Fernando L.
Breeding programs seek to reduce the time spent assessing characteristics more times than necessary. However, this reduction should in no way undermine the representativeness and reliability of the information. Thus, an important success factor in breeding programs is the knowledge of the ideal number of assessments needed to evaluate commercially important characteristics in each species or population. In this context, this study aimed to determine the repeatability coefficient of eight biometric traits in four populations of ornamental pepper, seeking to increase the efficiency of evaluation and selection processes. There was no significant influence of the calculation method used over the estimate of the repeatability coefficient. The results indicated...

Heterosis and combining ability for ornamental chili pepper
Provedor de dados: 75
Autores: Silva,Camila Q; Rodrigues,Rosana; Bento,Cíntia S; Pimenta,Samy.
ABSTRACT Ornamental use of Capsicum genus chili peppers has expanded due to easy seed propagation, short germination period, diversified fruit colors and harmony of potted plants. The ornamental plant sector requires cultivars adapted to different cultivation conditions in pots and gardens. Breeding programs can use heterosis and combining ability information, aiming to commercially explore hybrids or develop populations for lineage selection with desirable characteristics. However, the ornamental chili pepper field lacks studies with this data. In this study, combining ability of C. annuum accessions was determined for ornamental purposes and hybrid combinations were identified based on heterosis values. Fifteen hybrids were obtained from diallel crosses...

Provedor de dados: 75
Autores: Nass,Luciano L; Souza,Karina RR; Ribeiro,Claudia SC; Reifschneider,Francisco JB.
ABSTRACT: The establishment of populations with ample genetic variability and their use in breeding programs are discussed based on the Capsicum breeding program at Embrapa. Thirty-one accessions of "Habanero" pepper from different origins present in the Capsicum Active Germplasm Bank (AGB) of Embrapa Vegetables were used to establish a base population. The base population of "Habanero" was formed by an equal mixture of F2 seeds from all crosses obtained, using a fixed weight (1 g) per cross, which is close to 150 seeds per genotype. This balanced population was introduced in theCapsicum AGB as CNPH 15,469. There are several possibilities to explore this variability, such as the use of base population as source of inbred lines; the use of base population...

ABSTRACT Dual-purpose tomato breeding, for table and industry, has great importance for tomato production and strong impact on Brazilian socioeconomic development. In the present study, we used the methodology of mixed models to estimate the combinatorial ability of five tomato lines evaluated in complete diallel scheme without reciprocal, and cluster analysis to prospect new double and triple hybrids constitutions. Thus, we observed that positive values of general combining ability occur in ‘B13LD’, ‘Viradoro’ and ‘Rio Grande’ (for fruit firmness), ‘B13LD’, ‘Castone’ and ‘Massag-72’ (for soluble solids content); and ‘Viradoro’ and ‘Rio Grande’ (for productivity). The crosses ‘B13LD x Rio Grande’ and ‘Massag-72 x Viradoro’ showed positive estimates of...

A escolha dos reprodutores é fundamental para a atividade pecuária, pois é a partir do que é reproduzido que estabeleceremos um processo de melhoramento genético animal, em harmonia com o sistema de produção, seja ele qual for. Assim, colocar na ponta do lápis o incremento de produção com a utilização de touros melhoradores em função da relação touro:vaca e da fertilidade do rebanho, é o que justifica o investimento. Desse modo, aumentar a taxa de natalidade, juntamente com a qualidade desses animais nascidos, é o objetivo de todo pecuarista.

Use of horticultural practices in citriculture to survive Huanglongbing.
Provedor de dados: 14
Autores: STUCHI, E. S.; GIRARDI, E. A.
Citriculture is one of the major activities of the Brazilian agribusiness found throughout the entire country in different production environments. The presence of the Huanglongbing (HLB), reported in Brazil in 2004, has led to severe losses in important producing regions, challenging the sustainability of the citrus chain. Current control strategies are based on the use of healthy nursery trees, scouting and systematic eradication of symptomatic plants and chemical control of the insect vector. Research is being carried out at Embrapa and other Brazilian institutions aiming HLB resistance through genetic breeding via biotechnology. However, the inherent limitations to these actions determine that non-excluding and additional propositions could be...

Autores: VASCONCELOS, M. J. V. de; FIGUEIREDO, J. E. F.
Nos últimos anos, a tecnologia de edição genômica baseada no uso de nucleases “engenheiradas” ou quiméricas está revolucionando as abordagens de engenharia gênica e ampliando o repertório de animais e plantas geneticamente modificados, o que era impossível de ser obtido com as tecnologias tradicionais de manipulação gênica. O sistema enzimático quimérico CRISPR-Cas é uma poderosa ferramenta que permite realizar modificações genéticas precisas e específicas nas cadeias de DNA ou gerar rearranjos genômicos. Entre as aplicações de CRISPR/Cas, destacam-se as alterações da expressão gênica por meio do silenciamento, repressão, indução e ganho de função; modulação e alteração da atividade de proteínas; introdução de genes exógenos para induzir novas...

Genetic improvement of common carp (Cyprinus carpio L.)
Provedor de dados: 5
Autores: Vandeputte, Marc.
Common carp was the first domesticated fish species and is now a major species in worldwide aquaculture. Although research has generated a considerable body of knowledge about its genetics, genetic improvement programmes are virtually non-existent in this species and only crossbreeding is used in practice. The main reasons are the inefficiency of methods usually effective in other aquaculture species (monosexing, triploidy), and the bad image of selective breeding which is difficult to implement in ponds, and for which reliable genetic parameters were missing until recently. These parameters are now becoming available through the use of parentage assignment with microsatellite markers. However, the question of selective breeding for growth remains far from...

"First class oysters" : progress and constgraints in genetic improvement of the Pacific oyster (Crassostrea gigas)
Provedor de dados: 5
Autores: Boudry, Pierre.
The most significant genetic improvement for the production of Pacific oyster (Crassostrea gigas) up until now has been obtained through the production of triploids, particularly since the development of tetraploids in the mid 90s. Alternatively, quantitative genetics studies suggest that significant gains could be obtained in traits of aquacultural interest. However, the limited extent of hatchery propagation (compared with natural recruitment) in some countries and/or technical difficulties and biological characteristics of this species have retarded the development of selective breeding programs for C. gigas. Individual selection can however be performed easily in such a highly fecund species, though it often leads to small effective population sizes...

First evaluation of resistance to both a California OsHV-1 variant and a French OsHV-1 microvariant in Pacific oysters
Provedor de dados: 5
Autores: Divilov, Konstantin; Schoolfield, Blaine; Morga, Benjamin; Dégremont, Lionel; Burge, Colleen A.; Mancilla Cortez, Daniel; Friedman, Carolyn S.; Fleener, Gary B.; Dumbauld, Brett R.; Langdon, Chris.
Background Variants of the Ostreid herpesvirus 1 (OsHV-1) cause high losses of Pacific oysters globally, including in Tomales Bay, California, USA. A suite of new variants, the OsHV-1 microvariants (μvars), cause very high mortalities of Pacific oysters in major oyster-growing regions outside of the United States. There are currently no known Pacific oysters in the United States that are resistant to OsHV-1 as resistance has yet to be evaluated in these oysters. As part of an effort to begin genetic selection for resistance to OsHV-1, 71 families from the Molluscan Broodstock Program, a US West Coast Pacific oyster breeding program, were screened for survival after exposure to OsHV-1 in Tomales Bay. They were also tested in a quarantine laboratory in...

Autores: Oyeyemi,Matthew Olugbenga; Adeniji,Deborah Adejoke.
The morphological characteristics and haematological studies were studied in fifteen male albino rats (Wistar Strain) aged between 12 and 14 weeks and with a body weight of 150- 180g. The rats were allowed to feed on commercially prepared rat pellet and provided with fresh water ad libitum. The rats were divided into three groups; the rats were in groups A, B and C of 5 rats each. Group A served as control of the study; Group B was treated with Chloramphenicol at the dose rate of 25mg/kg body weight per os for 20 days; while Group C was treated for 25 days. Semen used in this study was obtained from the caudal epididymides while morphological aberrations were determined from spermatozoa counted after stained with Wells and Awa stain. Results of the...

Next-generation phenotyping in plants: old problems, new promises
Provedor de dados: 46
Autores: Breccia,G; Nestares,G.
Current progress in DNA sequencing technology has enabled to gather a large amount of genomic information. Genotyping has become a routine activity with lower costs as new technology emerges. However, genomic information cannot provide much insight into how a given genotype performs. In fact, improvement in understanding phenotypes and the ability to generate good phenotypic data became essential for better utilization of genotypic data and understanding the effect of environment. In this post-genomic era, phenomics emerge as a new discipline that aims the acquisition of high-throughput phenotypic information at all levels of biological organization integrating different &amp;#8220;omics&amp;#8221; data. New technology in plant phenotyping comprises a wide...

Pollen of Syzygium (Myrtaceae) from SE Asia, especially Thailand
Provedor de dados: 16
Autores: Parnell, J.
Pollen of 57 species of Syzygium from SE Asia were surveyed by SEM. The grains are all ± triangular in polar view, uniformly small (mean diameter 10.4 μm) with few surface sculpturing features. All species examined exhibit a distinct apocolpium and, usually, apocolpial field. The presence of an apocolpial field cannot be linked to any known taxonomic grouping within the genus. It does not appear possible to distinguish the species of Syzygium on the basis of features of the pollen visible under SEM, though section Jambosa tends to have larger pollen with a proportionally larger apocolpium than species not in that section. Estimates for the number of pollen grains per stamen in species with larger pollen grains (± section Jambosa) are 5× as great as for...

Reproductive and population parameters of discus fish Symphysodon aequifasciatus Pellegrin, 1904 (Perciformes: Cichlidae) from Piagaçu-Purus Sustainable Development Reserve (RDS-PP), lower Purus River, Amazonas, Brazil
Provedor de dados: 83
Autores: Rossoni,Felipe; Amadio,Sidinéia; Ferreira,Efrem; Zuanon,Jansen.
The ornamental discus fish Symphysodon aequifasciatus Pellegrin, 1904, is a popular endemic cichlid species from the Amazon basin, however scientific information concerning biology and ecology in its natural habitat is scarce despite its importance on the international aquarium trade. In this study we evaluated reproductive parameters of S. aequifasciatus in natural habitat in Piagaçu-Purus Sustainable Development Reserve (RDS-PP), lower Purus River, Brazilian Amazon. Males are more frequent in the larger size classes and this might be related to the complex breeding behavior known for S. aequifasciatus. Values of L50 for both sexes corresponded to more than 60% of the maximum attained length which may indicate that energy allocation for somatic growth...

Metaplasia in swim bladder epithelium of the endangered annual fish Austrolebias nigrofasciatus (Cyprinodontiformes: Rivulidae) results in inadequate swimming and delayed growth
Provedor de dados: 83
Autores: Fonseca,Alinca Peres da; Volcan,Matheus Vieira; Romano,Luís Alberto; Robaldo,Ricardo Berteaux.
ABSTRACT Laboratory breeding of annual fish is often impaired when fish fail to inflate the swim bladder after hatching. These fish, which are known as belly-sliders, cannot swim in the water column, moving mainly on the bottom of water. Therefore, we wanted to understand the factors underlying failed inflation of swim bladder in the annual fish Austrolebias nigrofasciatus and determine the implications of this condition on the growth of juveniles. To identify how the initial filling of the gaseous vesicle is compromised, and to determine the implications of this condition on juvenile growth, we analysed the histology of the swim bladder of both normal swimming fish and belly-sliders during their initial growth phase (first month of life). In addition to...

Autores: Ammer, Stefanie; Quander, Nele; Posch, Julia; Maurer, Veronika; Leiber, Florian.
Les performances de croissance de mâles d’hybrides de ponte recevant une alimentation comportant des sources et des teneurs différentes en protéines ont été étudiées dans trois essais d’engraissement. Par rapport aux hybrides d’engraissement Hubbard JA 757 (HUB), les poulets mâles des génotypes Lohmann Braun (LB) et Lohmann Selected Leghorn (LSL) présentent une moins bonne performance d’engraissement. Le poids vif, la prise de poids journalière et le poids à l’abattage sont influencés par le génotype.  Les mâles LB présentent cependant de nets avantages en termes de performance par rapport aux mâles LSL.

Prüfung von Zuchtlinien der Weißen Lupine (Lupinus albus L.) auf Anthraknoseresistenz
Provedor de dados: 21
Autores: Jacob, Irene; Deyerler, Manuel; Feuerstein, Ulf; Geißendörfer, Herbert; Heinz, Markus; Schweneker, Dörte; Urbatzka, Peer.
White lupin (Lupinus albus L.) is a protein plant adapted to the conditions of middle Europe. Presently, no variety with a sufficient resistance to anthracnose, caused by Colletotrichum lupini, is available, and cultivation of white lupins in Germany has hardly any relevance. Making this crop available for cultivation again would expand the range of domestic protein crops and increase the biological diversity on agriculturally used fields.   To make this crop worth cultivated again, it is essential to develop white lupin varieties with a high resistance to anthracnose. The breeding lines tested in this study proofed to have a higher level of resistance towards anthracnose and are thus yielding higher compared to currently available varieties.

Emergence time and skin melanin spot patterns do not correlate with growth performance, social competitive ability or stress response in farmed rainbow trout
Provedor de dados: 21
Autores: Gesto, Manuel; Skov, Peter V.; Jokumsen, Alfred.
In wild salmonid fish, specific individual behavioral traits have been correlated with the timing of fry emergence from their gravel spawning nests; Early emerging fish display more aggressive behavior and have a higher probability of becoming socially dominant, compared to fish that emerge at a later stage. Apart from aggression and dominance, other behavioral and metabolic traits, such as boldness, metabolic rate, or growth, have also been linked to emergence time. Altogether, the traits of early- and late-emerging fish resemble those of the proactive and reactive stress-coping style, respectively. As proactive fish are considered more resilient to stress, it may be desirable to select these for aquaculture production. However, it is currently unclear to...

Strategic use of virulence pattern to develop genetic markers for resistance to common bunt (Tilletia caries) in wheat
Provedor de dados: 21
Autores: Borgen, Anders; Backes, Gunter; Müller, Karl-Josef; Spieß, Hartmut.
When assesssing races of common bunt for virulens pattern within a region, it is important to take into account that collected spores may represent a diverse population of different virulence races.  When screening spores on a differential set of wheat lines with known resistance genes, a low infection rate on a resistant wheat variety does not necessarily demonstrate that virulence is absent in the spore collection, but could be a sign that virulence is present, but only present in a low frequency among the spores. If just a few spores within a spore sample are indeed virulent, they may infect some plants and from there multiply the virulence quite rapidly next years. Previous studies have shown that virulence against most resistance genes were present in...

Green Breeding: Bioimpuls Programme 2009-2013  -  Perspectives on  Phytophthora-resistant potato varieties
Provedor de dados: 21
Autores: Scholten, Olga E.; Lammerts van Bueren, E.T.
The heavy outbreaks of Phytophthora in 2007, and again in 2012, reconfirmed the need for resistant potato varieties for the organic sector. Until recently no such varieties were available. In 2009 the Bioimpulsprogramme was launched to give more priority to breeding organic, Phytophthora-resistant varieties. In this 10-year programme, wild potato species are crossed with cultivated potato to develop new resistant varieties. Although this classical breeding strategy is a long road, the advantage is that you can select for multiple traits along the way. This brochure presents the results of the first four years of the programme.

Autores: Dierauer, Hansueli; Kupferschmid, Cornelia.
Futterweizen ist für Landwirte, die auf Biolandbau umstellen eine wichtige Kultur. Bisher gab es für Biobauern nur eine empfohlene Sorte, nämlich Ludwig (Klasse II Weizen). Auf nährstoffreichen Betrieben wäre es möglich, mit echten Futterweizensorten mehr Ertrag zu erzielen. So kann die Preisdifferenz zu Brotweizen ausgeglichen werden. Die Umstellung auf Bio soll durch ertragsstarke Futterweizen gefördert und attraktiver gemacht werden. Dies benötigt neue, ertragsreichere Sorten. Die Qualität des Futterweizens ist dem Ertrag untergeordnet.  Bestehende Biobauern haben auch die Möglichkeit, für die Biofarm Flocken zu produzieren. Sie sind an neuen Sorten und an Alternativen zu Ludwig interessiert, da dieser nicht auf allen Standorten befriedigende Erträge...

Spring forms of spelt landraces (Triticum spelta L.) and their suitability for Organic Farming
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan (Jr.); Moudry, Jan.
Organic farmers are interested in the growing of spring spelt wheat forms (Triticum spelta L.). Therefore, the important agronomical characteristics and baking quality of  six spring spelt wheat landraces were studied and evaluated. The studied and evaluated cultivars were inclined to lodging and wheat diseases. Their yield rate is  determined by the length of the spike and the weight of one thousand grains. The grain yield and the crude protein yield per hectare achieved the same level in organic farming. The spring spelt wheat forms stand out in high protein content and wet gluten content; the gluten was, nevertheless, weaker and less swollen.

Small grains provide numerous benefits for organic farming systems. However, because they have relatively low value and require special equipment, many organic farming systems do not integrate them. Heritage varieities of ommon wheat (Triticum aestivum ssp. Aestivum) and its antecedents spelt (Triticum aestivum, ssp. spelta), emmer (Triticum turgidum subsp. dicoccum) and einkorn (Triticum monococcum) are the subject of a project that looks at their viability.  Preliminary results of variety trials show that organic farmers have several promising small grain options. Improved management and appropriate equipment are barriers to adoption that the project aims to overcome. Viability will depend on overcoming marketing as well as production obstacles.

Root growth vigour is a better predictor than root hair traits of early nutrient uptake in spring wheat plants grown at low soil fertility
Provedor de dados: 21
Autores: Wang, Yaosheng; Thorup-Kristensen, Kristian; Jensen, Lars Stoumann; Magid, Jakob.
Background and Aims A number of root and root hair traits have been proposed as important for acquisition of P. However, it remains unknown whether these traits are most important in determining macro- and micronutrient uptake at low soil fertility. This study investigated the variations in root and root hair traits among spring wheat genotypes and examined which root and root hair traits are most important for high uptake of macro- and micronutrients.   Methods Six spring wheat genotypes were grown in a soil with low nutrient availability. The root and root hair traits as well as the content of macro- and micronutrients were identified.   Results A significant genetic variability in root and root hair traits was found. High root growth vigour and long and...

Incentives and constraints for the use of organic seeds in organic farming: example of Capsicum annuum seeds in the Netherlands and Spain
Provedor de dados: 21
Autores: Brühl, Katharina.
The EU legislation on organic farming was aimed at forcing the use of organic seeds in organic production. However, there are striking differences in its implementation across the EU and the use of organic seeds is still sparse. This study examines the use of organic seeds for sweet pepper (Capsicum annuum L.) production in a pilot study for the Netherlands and Spain. In order to identify existing incentives and constraints, a supply chain analysis is applied, derogation requests for using non-organic seeds are analysed and interviews with stakeholders of the supply chain are conducted. Based on the findings, recommendations are given on how each stakeholder can participate in improving the implementation of the EU law, promoting the use of organic seeds.

Over the past 40 years, dairy cow breeding has led to very high yielding cows (more than doubled average annual milk yields in most dairying countries), but also to a deterioration in cow health, fertility and longevity (Pryce et al. (1999)). Consequently, many breeding organizations all over the world are seeking to include functional traits in their breeding programmes (Groen et al. (1997), Christensen et al. (1998)). A great amount of research is done on potential index traits for indirect selection for health traits (Groen et al. (1997)). The whole constitution of the animals is to some extent considered in Scandinavian breeding programmes using the epidemiological data of all herd book animals (Philipsson et al.

Pushing forward white lupin as a local source for protein and nitrogen in Central Europe
Provedor de dados: 21
Autores: Rosenfeld, Simon; Voegele, Ralf T.; Messmer, Monika; Finckh, Maria R.; Szuszkiewicz, Roderick; Oberhänsli, Thomas; Hohmann, Pierre.
White lupin (Lupinus albus L.) is a promising leguminous crop. Europe is fully dependent on protein and nitrogen fertilizer imports. This has tremendous negative effects both in Europe and the producing countries, such as loss of terrestrial biodiversity, pollution of freshwater, increase of greenhouse gases and soil acidification. Diverse crop-rotations with a substantial amount of pulses are a proven solution. The protein composition and yield potential of white lupin suggest that it could become the ‘Soy of the North’.  Currently, the seed-borne pathogen Colletotrichum lupini is substantially impeding the cultivation of white lupin in Central Europe. We developed a DNA-based diagnostic test to identify and quantify the fungal pathogen in plants and...

Untersuchung europäischer Hafersorten auf Resistenz gegenüber Haferflugbrand  (Ustilago avenae)
Provedor de dados: 21
Autores: Herrmann, M.
Für den ökologischen Anbau von Hafer stellt der Haferflugbrand ein wirtschaftliches Risiko dar, da Flugbrand den Ertrag reduziert und die Saatguterzeugung gefährdet. Ein effektiver Lösungsansatz für dieses Problem wäre eine gezielte Resistenzzüchtung, wofür grundlegende Fragestellungen im Rahmen des Projektes zu untersuchen waren. So war eine Resistenzprüfmethode zu etablieren, ein breites Hafersortiment auf Resistenz zu prüfen und verschiedene geografische Herkünfte von Ustilago avenae hinsichtlich ihrer Virulenz zu testen. Am Ende des Projektes sollten die Chancen für eine erfolgreiche Resistenzzüchtung eingeschätzt werden können.

Emmer wheat [(Triticum dicoccum Schrank (Schuebl)] is after bread, durum and spelt wheat further species of wheat  used for economic purposes. Organic farmers and producers have become more and more interested in marginal crops  such as the tetraploid emmer wheat because of its suitability for organic farming. In spite of its historical role, present distribution of emmer is very limited. The work analyzes the problem of growing possibilities of emmer and its suitability for cultivation in organic farming. In the Czech Republic it is grown only a few farms, but in Austria is more popular now. Possible candidates for the cultivation of emmer has several options about where to obtain a suitable variety. The best option appears to be the choice of legally...

Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer...

Under organic farming conditions, twenty safflower genotypes were tested for genotype-by-environment interaction (GxE) and stability across four locations in Germany and Switzerland for seed yield and oil content.. ANOVA showed highly significant differences among the genotypes, locations and GxL interactions for yield and oil content. None of the genotypes had a significant regression coefficient or a mean square deviation from the regression coefficient, thereby all genotypes are considered stable for seed yield, whereas, BS-62929 and PI-5724755 were relatively the most stable for oil content.

RobustFish vil styrke udviklingen af økologisk ørred produktion i Danmark. Ifølge EU regelsættet for økologisk akvakultur skal den økologiske fiskeproduktion udelukkende være baseret på økologisk yngel fra 2016. Da medicinbehandling af økologisk ørred er uønsket og kun er tilladt i stærkt begrænset omfang, er ynglens robusthed overfor bl.a. den alvorligste yngelsygdom i dansk ørredopdræt, YDS (”yngeldødeligheds-syndrom”), særdeles vigtig. Ynglens robusthed vil blive målt i forhold til ynglens swim-up adfærd (first feeding) og performance under opvæksten. Indholdet af specifikke essentielle Ω-3 fedtsyrer i foderet til ynglen er særlig vigtig for fiskens vækst, sundhed og velfærd, herunder robusthed overfor stress.

Gastro-intestinal nematodes (GIN) are the most important problem in small ruminant  production with regard to animal welfare and economics. The control of GIN currently  relies almost exclusively on the use of synthetic anthelmintics. This is unsatisfactory  for organic as well as for conventional small ruminant farmers because of rapid increase  of resistant GIN populations and risk of residues in meat and milk. Alternatives  to synthetic anthelmintics are therefore needed. This poster presents the main alternative  control strategies for GIN.

Hva slags korn trenger vi å foredle i Norge?
Provedor de dados: 21
Autores: Løes, Anne-Kristin.
The paper refers a field day arranged in stange, Hedmark in July 2016 to learn about cereal breeding with the national breeding company, Graminor, which also has an interest to breed varieties for organic growing. Increased interest is also found for varieties with high qualities for food consumption, such as higher contents of micro minerals, where old varieties often have higher contents than modern varieties. Breeding for high gluten contents to produce high loafs is controversial and some blame modern varieties for contributing to the increased intolerance for industrial cereal products.

Agronomic characteristics of the spring forms of the wheat  landraces (einkorn, emmer, spelt, intermediate bread wheat)  grown in organic farming
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming system. In summary, our fi ndings show that einkorn (Triticum monococcum L.) and emmer wheat [Triticum dicoccum Schrank (Schuebl)] are resistant to powdery mildew and brown rust, spelt wheat (Triticum spelta L.) is less resistant to these two diseases, and the intermediate forms of bread wheat are very sensitive to such infestation. The  varieties evaluated incline...

Reduction of boar taint - the practical way
Provedor de dados: 21
Autores: Jensen  , Bent Borg; Maribo, Hanne; Thomsen, Rikke.
The aim of organic pig production is to ensure high animal welfare and natural products. Banning castration is thus a logical step forward, but the risk of boar taint in the meat is a major barrier for marketing meat from entire male pigs. Is it possible to use genetic tools and breeding strategies to prevent boar taint? What is the effect of feeding, management, housing and hygiene? Is it possible to process the meat to minimize the risk of boar taint? These issues will be discussed based on the results from the research project NOCAST, as well as other on-going Danish research projects on entire male pigs.

The Critical Point of Conventionally Bred Soft Wheat Varieties in Organic Farming Systems
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Moudry, Jan.
Nowdays, wheat is the most important crop for organic farming system. However, the varieties breeded and tested in the conditions of organic farming system are still missing. It gives rise to very low level of yield in the Czech Republic (less than 50% of level of convention  one in the same conditions). One of the reasons is that the ideotype of organic breeded variety is different from conventional one. The varieties suitable for organic farming system differ in many respects from those adopted in conventional farming. The first difference is obvious from the conventional tests of use value of the varieties, taking just some direct indicators influencing the main parameter (yield) into account. Generally speaking, the features to be tested can be divided...

Alors qu’il semble désormais acquis que l’AB nécessite des variétés adaptées, la sélection reste encore trop souvent centralisée en station expérimentale. Le développement de réseaux de fermes biologiques permet de proposer une sélection décentralisée prenant en compte une large gamme de conditions de culture. Cependant les indicateurs agro-écologiques et socio-économiques sont difficiles à appréhender dans de tels réseaux. L’objectif du projet est de voir de quelle manière la sélection participative, faisant intervenir l’agriculteur dès les premières étapes du programme de sélection, peut permettre d’aller plus loin que la sélection décentralisée dans la compréhension et  la maîtrise  des interactions GxE.

Within a pasture genetics project 540 cows with a common German Holstein sire (VG)  served as comparison group for 110 daughters of “pasture sires” from Germany suited  to grazing conditions (D) and 150 cows with a New Zealand sire (NZ). According to  the pasture amount (PA) from May to October the 22 farms were separated into three  groups. Mean yields for milk were decreasing from  20-23kg/day to 19-20kg/day when PA increased. In farms with PA of &gt;60% the pasture genetics (NZ and D) were superior. Mean fat and protein contents of the milk were generally higher for daughters of NZ sires. These cows also needed least time until mating after their first calving and were less susceptible to hock lesions and lameness. Daughters of D bulls had the most hock...

Autores: Knudsen, Jens; Larsen, John; Bødker, Lars; Jørnsgård, Bjarne; Jensen, Birgit.
The possibility of improving resistance in pea against the root pathogen Aphanomyces euteiches using composite cross as a breeding and selection method was examined. In order to maintain acceptable agricultural features and high yield 6 out of the 8 parental varieties in the present composite-cross were commercially grown varieties. Populations of the composite cross were grown up to five generations with selection pressure in soil heavily infested with pea root pathogens or without selection pressure on soil free of pea root pathogens. Yield of populations of the F9 and F10 generations of the composite cross grown with selection pressure was on average 35% higher than that of the population obtained without selection pressure as well as the average yield...

Robuuste rassen, weerbare bioteelt
Provedor de dados: 21
Autores: Dewaele, Karel; Dewitte, Justine.
Biologische teeltsystemen hebben minder stikstof beschikbaar dan de gangbare teelt. Door de mestwetgeving wordt deze beperking de komende jaren nog dwingender. Daarnaast worden door de verandering van het klimaat in onze regio meer extreme weersomstandigheden over een langere periode (vb. warmte, droogte,…) verwacht. Hierdoor wordt de impact van ziekten en plagen mogelijk ook groter. Veredeling en teelttechniek moeten hierop antwoord kunnen bieden om tot robuuste gewassen te komen. In dit project hebben Inagro en PCG vier concrete cases getest.    Case 1: Maximale diversiteit in het graanveld met CCP’s  Case 2: Aardappelrassen gemengd telen vertraagt Phytophthora-verspreiding  Case 3: Stikstof- en waterefficiënte broccoli  Case 4: Buitenteelt tomaat

Autores: Dewaele, Karel; Delanote, Lieven; Temmerman, Femke.
In het Europese project ‘COBRA’ onderzoekt Inagro samen met andere Europese partners in hoeverre nieuwe veredelingsconcepten de weerbaarheid van granen tegen verschillende stressfactoren (vorst, ziekte, droogte,…) kunnen verbeteren. Samengestelde kruisingspopulaties ontstaan uit een kruising van verschillende rassen waarbij de zaadoogst van de gehele populatie wordt gebruikt om een volgende generatie te creëren. Op die manier ontstaan populaties met een extreem hoge genetische diversiteit.   In een verkennende proef op het biologisch proefbedrijf van Inagro bleken deze populaties onder hoge druk van gele roest alvast niet onder te doen voor enkele referentierassen wintertarwe uit Noord-Frankrijk.

Management practices’ effect on milk production, somatic cell count and mastitis in Swedish organic dairy farms
Provedor de dados: 21
Autores: Wingren, Josefin.
The most common animal health problem in organic dairy production is mastitis. It is considered to be one of the most serious welfare problem in dairy production, as well as an economic problem as it often leads to a reduced milk yield and reduced profit. To combat this problem, the focus in organic dairy production is laid on management strategies to e.g. reduce the use of antibiotics and improve the animal health and welfare. In 2015, the EU-funded project OrganicDairyHealth started in seven European countries, including Sweden. Within the project, an extensive survey on housing, management, health and production was sent out to organic dairy farmers in each country, and this thesis is based on the data from the Swedish survey.

Organic plant breeding
Provedor de dados: 21
Autores: Wolfe, Martin S.
This report was presented at the UK Organic Research 2002 Conference. To a major extent, organic farming depends currently on plant and animal varieties that have been bred for non-organic farming and that are often not suited to organic production. This position is inconsistent with a holistic approach to organic agriculture. Organically-bred plant varieties are needed to develop both the potential of organic agriculture and its integrity. A first attempt at developing a concept for organic plant breeding methodology has been proposed. A novel approach to breeding for organic production has also been started. Further development needs a parallel approach to animal breeding for organic systems.

Conservation of livestock genetic resources by targeted on-farm management: a case study of Hinterwälder Cattle in the Southern Black Forest
Provedor de dados: 21
Autores: Wanke, Diethild; Boehncke, Engelhard.
This report was presented at the UK Organic Research 2002 Conference. All EU countries are obliged to conserve livestock genetic resources (UN Convention on Biological Diversity, Rio, 1992). In-situ conservation is regarded as the most favourable approach. For rare and endangered livestock breeds extensive and organic farming systems seem appropriate. Council Regulation (EC) No 1804/1999 on organic farming recommends keeping indigenous breeds and strains that have adapted to local conditions. This project analyses the current situation and develops future scenarios for Hinterwälder farms.

Faisabilité technique et économique de plants fruitiers dans le cadre de l’Agriculture Biologique
Provedor de dados: 21
La production de plants fruitiers en agriculture biologique est un verrou technique autant qu’économique, qu’il faut lever pour répondre à la législation prévue. Le programme présenté vise à acquérir des références sur deux espèces fruitières majeures, le pommier et le pêcher, afin d’orienter par la suite les pratiques culturales des pépiniéristes souhaitant proposer des plants certifiés AB. La question de recherche proposée concerne la stimulation des défenses naturelles, des test préliminaires sous serre permettant d’affiner un choix d’application au champ. Le matériel végétal, ainsi que la densité de plantation, la conduite culturale et l’entretien du rang font également partie des points techniques à renseigner.

The Significance of Sustainable Breeding and Management Programs on Reproductive Performance in Norwegian Red Cows
Provedor de dados: 21
Autores: Garmo, Randi Therese.
The breeding program for the Norwegian Red breed over the last 35 years has included fertility, health and functional traits in addition to milk yield and other production traits. Currently, the demands placed on individual cows are increasing particularly in regards to milk yield, dry matter intake, fertility, and longevity. The overall goal for the four studies included in this thesis was to assess the reproductive performance in modern Norwegian Red cows.  In the first field study, the 60 d non return rate, pregnancy incidence, calving rate and differences between non return rate and pregnancy incidence following first artificial insemination (AI) were investigated. None of the animals were treated with reproductive hormones prior to AI. The proportion...

Current situations in organic cereal seed offer in the Czech Republic
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Capouchova, Ivana; Huda, Petr; Moudry, Jan; Moudry, Jan (Jr.).
Organic farmers are obliged, in compliance with the valid legislation, to use seed originating from the organic production when establishing the crop stands. In a survey we found certified organic cereal seed is used on 6 %, conventional untreated seed on 37 %, and farm seed on 57 % (of the organically farmed area in the Czech Republic). The main reasons for that are as follows: the insufficient surface of land intended for the reproduction of organic seed, the low proportion of accepted seed coming from the accepted reproduction surface. Therefore, low-quality farm seed is used on a large proportion of organically farmed land, which has a negative effect on the yield level of the cereals. These observations were also confirmed by results obtained in a...

Breeding for microbiome-mediated disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Bodenhausen, Natacha; Messmer, Monika.
Plant-associated microbial communities play a crucial role for the expression of various plant traits including disease resistance. Increasing evidence suggests that host genotype influences the composition and function of certain microbial key groups, which, in turn, effects how the plant reacts to environmental stresses. Several studies indicate that modern plant breeding may have selected against plant traits essential for hosting and supporting beneficial microbes. However, they also highlight the presence of an exploitable genetic base for the regulation of the rhizosphere microbiota.  We illustrate the concept of breeding for microbial symbioses with pea (Pisum sativum L.). Firstly, genotypic variation for the efficiency of a mycorrhizal symbiosis is...

The impact of seed source (conventional or organic farming) is one important question for the variety trials under the conditions of organic farming. Hence, field trials were  conducted at two sites in Bavaria in two years (2013-2014). Certified organic seed from a Bavarian propagation were compared to conventional seed, offered by breeders for national variety trials. One until two varieties were examined for winter rye and for winter triticale in each year. Organic seed often showed higher crude protein content, conventional seed had mainly  higher thousand seed weight and often superior germination power.  The grain yield was mostly higher for conventionally produced seeds than for organic seed at one site, whereas seed source showed no differences with...

Managing crop nitrogen and soil dynamics
Provedor de dados: 21
Autores: Salon, Christoph; Hauggaard-Nielsen, Henrik.
Despite extensive research grain legume seed protein content and yield remains low and unstable.   Grain legume performances in the cropping system are highly dependent upon N nutrition of the crop relying on root assimilation of soil N in combination with symbiotic fixation of atmospheric dinitrogen. In order to improve the competitive ability of grain legumes for growth resources an enlargement of the crop surface area production in combination with a judicious management of both inputs and N acquisition (and allocation to the harvested organs) is needed. Competitive ability implies to take into account economical constraints and the crop production effect on the environment, reducing the amount of N remaining after the crop harvest preventing N...

Kinship breeding is recommended as an adequate breeding approach for organic farms, because breeders work with their own well adapted cow families and bulls. Therefore kinship breeding is promoted on organic farms in a project conducted in Switzerland and Germany. An often arising question is about a possible negative impact of inbreeding on animal health, performance and welfare, but there is not much and quite varying information available. Therefore, a literature study and 10 interviews with dairy cattle breeding experts were conducted to get a better knowledge on inbreeding impacts in small populations. Results: Inbreeding depressions were described for production, sperm quality and quantity, reproduction, calf vitality, longevity and calving traits...

Die Angaben aus Praktikerkreisen, dass Hybridsaatgut von Möhren per se schneller aufläuft und höhere Feldaufgänge hat als solches samenfester Sorten, konnte nicht bestätigt werden. Hier festgestellte Unterschiede im Feldaufgang hatten keinen Einfluss auf den Gesamtertrag an Rüben. Mit Blick auf die Jugendentwicklung und den Ertrag hatte die Wahl größerer Saatgutkaliber keinen Vorteil; es ist jedoch nicht auszuschließen, dass die Größe der Samen auf die Ausprägung äußerer wie innerer Qualitäten einen Effekt hat. Die Erträge der Hybriden lagen deutlich über denen der samenfesten Sorten.

N Uptake at EC 32, 62 and 92 was determined in 6 wheat varieties in field trials under conditions of conventional and organic farming over 3 years. Root growth potential was assessed in a separate trial under controlled conditions. Rank of varieties regarding N-uptake was dependent on yield level of the test environments and was mainly due to differences in uptake during grain filling. In one variety high N uptake potential coincided with high root growth in later growth stages.

Naturlig modstandskraft er vigtig i fremtidens økologiske produktionssystemer for at opfylde markedets krav og forbedre den overordnede produktivitet. Men udviklingen af et robust immunsystem vil sandsynligvis være på bekostning af andre funktioner såsom vækst og reproduktion. I Organic RDD projektet SUMMER har man undersøgt tarmsundhed og immunsystem hos forskellige afstamninger af slagtekyllinger  med forskellige vækstpotentialer Deimmunologiske undersøgelser viser, at der er forskel på de basale immunfunktioner mellem afstamningerne.

As bread wheat is the most important cash crops for French organic farmers, the question of the kind of varieties farmers should be using is therefore very important. Most of varieties available were bred for intensive “conventional” farming systems (with high inputs of mineral fertilizers and pesticides), also screening current varieties for organic conditions becomes a necessity to identifiy suitable varieties for organic farming conditions in a short term experiment. After 20 years of selection and screening combined in two different crop management systems, low inputs and organic, two lines, Hendrix and Skerzzo, have been registered in the official catalogue with the special mention « organic farming ».

Do endangered sheep breeds have an advantage in organic farming?
Provedor de dados: 21
Autores: Rahmann, G.
Endangered breeds are not compulsory for organic farming, but adapted and local breeds are considered suitable for Organic Farming. In the year 2001, 240 ewes of six different breeds were introduced on the experimental farm of the Institute of Organic Farming in Trenthorst. Two were high yielding breeds, four older endangered German breeds. The whole herd was kept in one herd in a low input – low output system, comparable to agrienvironmental schemes. The scientific programme was to follow the herd’s development in terms of health status, growth rate and product qualities.  After three lambing seasons, no real advantages could be found for the old breeds. Nevertheless, high yielding and old breeds did not show big differences in production and health...

In a decentralized and participatory plant breeding (PPB) program, in contrast to conventional plant breeding, farmers select from a large number of genotypes over a number of cycles in several locations. As selection is for location-specific adaptation a PPB program based on, for example, four stages of selection, generates large, unbalanced data sets. With common spreadsheet software it is not possible, or it is at least very cumbersome to extract all the information, particularly the one that is related to genotype x environment (GE) interactions. Therefore, there is a need for an information system that makes it as easy as possible to retrieve and compare data over all given factors in the PPB-program. Due to a lack of education and financial resources...

Differences in the Morphological Characteristics of the Land Races of the Soft and Emmer Wheat in Relation to the Modern Varieties
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Capouchova, Ivana; Moudry, Jan; Sramek, J.; Moudry, Jan (Jr.).
For the organic farmers there is important question which varieties of wheat are right for organic farming in Less Favoured Areas. Modern varieties of wheat are bred in the conditions of conventional (high imput) farming. That is why the organic farmers asked about the suitability of land  races of soft wheat (Triticum aestivum L.) or different species like emmer wheat grown in the past (Triticum dicoccum SCHUEBL). The paper results from the study of fourty land races, two intermediate and ten modern varieties of soft wheat in comparison to ten land races of emmer wheat at two locations in the Czech Republic. We evaluated tuft shape, length of plant, length and width of flag leaf, length and density of spike and awnedness. The  modern varieties of soft...

Genotype x Environment Interactions of Winter Wheat
Provedor de dados: 21
Autores: Hildermann, Isabell; Messmer, Monika; Kunz, Peter; Pregitzer, Anjana; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
Winter wheat cultivars for organic farming have to be adapted to highly variable environments. Yield and yield stability, the nutritional value and the bread making quality are here of major importance. Particularly, seed quality, tillering capacity, regeneration ability after harrowing, weed suppression ability, resistance or tolerance against diseases and improved nutrient use efficiency (NUE) under limited nutrient conditions need to be improved by specific breeding efforts (Kunz et al., 2006; Löschenberger et al., 2008).  Ten winter wheat cultivars were grown in 2007 in two organic systems of the DOK long-term experiment in CH-Therwil.  Eight of these cultivars were tested in 2008 at three organic farms in different pedo-climatic environments in...

In Deutschland werden im Ökologischen Landbau trotz vorhandener Nachfrage nach Speiseöl nur sehr wenige Ölpflanzen angebaut. Saflor oder Färberdistel ist dabei als eine sinnvolle Alternative zu Raps bzw. Sonnenblumen anzusehen, es liegen jedoch bislang nur wenige Untersuchungen zur Anbauwürdigkeit vor. 741 Saflorherkünfte wurden 2002 auf ihre Anbaueignung unter hiesigen Klimabedingungen zweiortig geprüft. 2003 wurden 65 daraus ausgelesene, überlegene Herkünfte in einer dreiortigen Leistungsprüfung getestet. Es zeigte sich neben einer sehr großen Variabilität des verwendeten Materials, dass sich vorrangig europäische Formen durch eine gute Kornausbildung und höhere Samenerträge auszeichneten.

Incentives and constraints for the use of organic seeds in organic farming: example of Capsicum annuum seeds in the Netherlands and Spain
Provedor de dados: 21
Autores: Brühl, Katharina.
The EU legislation on organic farming was aimed at forcing the use of organic seeds in organic production. However, there are striking differences in its implementation across the EU and the use of organic seeds is still sparse. This study examines the use of organic seeds for sweet pepper (Capsicum annuum L.) production in a pilot study for the Netherlands and Spain. In order to identify existing incentives and constraints, a supply chain analysis is applied, derogation requests for using non-organic seeds are analysed and interviews with stakeholders of the supply chain are conducted. Based on the findings, recommendations are given on how each stakeholder can participate in improving the implementation of the EU law, promoting the use of organic seeds.

Weaknesses of the emmer wheat genetic resources and possibilities of its improvement for low-input and organic farming systems
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan (Jr.); Moudry, Jan.
Emmer wheat is suitable for organic and low-input farming systems, as it contributes to the enhancement of agrobiodiversity and an extension of the range of crop species with a higher added value. Although it has been grown for a very long time, it is now rarely utilised. The results of research into and examination of six cultivars coming from the genetic resources of the gene bank in Prague are presented. Particular morphological, biological, economic and quality characteristics were examined in respect of a cultivar’s ideotype for the organic farming system. A number of criteria for selection were proposed on the basis of an examination of particular characteristics and relationships. They respect the principles of breeding of cultivars for the organic...

This study investigated the effect of, and interactions between, contrasting crossbreed genetics (US Brown Swiss [BS] x Improved Braunvieh [BV] x Original Braunvieh [OB]) and feeding regimes (especially grazing intake and pasture type) on milk fatty acid (FA) profiles. Concentrations of total polyunsaturated FAs, total omega-3 FAs and trans palmitoleic, vaccenic, a-linolenic, eicosapentaenoic and docosapentaenoic acids were higher in cows with a low proportion of BS genetics. Highest concentrations of the nutritionally desirable FAs, trans palmitoleic, vaccenic and eicosapentaenoic acids were found for cows with a low proportion of BS genetics (0–24% and/or 25–49%) on high grazing intake (75–100% of dry matter intake) diets.

THE SEED SOURCES OF ORGANIC FARMERS IN ITALY
Provedor de dados: 21
Autores: Bocci, Riccardo; Ortolani, Livia; Micheloni, Cristina.
This paper presents the result of the survey done in 2010 by AIAB on the seed sources in Organic Agriculture (OA) in Italy. The aim of this work is to better understand and clarify the relationships between the formal and informal seed system (Almekinders and Louwaars, 2000) and quantify the role of the latter in OA. In a time where the choice of the varieties to grow will be in the hands of public institutions or seed industries (GRAIN, 2008), it is pivotal to check the needs of Organic farmers and the seed they are sowing. The questions addressed were:  a. Are Organic farmers still self-producing seeds?  b. Are they using only varieties listed in Official National Catalogue?  c. What is the role of old varieties not listed anymore or local varieties in...

Ökologischer Sojaanbau in kälteren Gebieten Deutschlands?
Provedor de dados: 21
Autores: Paffrath, Andreas; Henneberger, Matthias; Mayer, Jochen.
Bisher können Sojabohnen in Deutschland nur in klimatisch begünstigten Gebieten wie z.B. im Raum Freiburg, der Oberrheinebene und in Südbayern einigermaßen erfolgreich angebaut werden. Aufgrund ihrer hohen Temperaturansprüche sind für Soja nur Lagen geeignet, in denen auch Körnermais angebaut werden kann. Die Aussaat erfolgt von Ende April bis Anfang Mai. Neuere Sorten könnten jedoch auch für den Sojaanbau in etwas kälteren Gebiete Deutschlands interessant sein.    Zur Klärung dieser Frage wurden im Jahr 2001 am Gartenbau-Zentrum Köln-Auweiler der Landwirtschaftskammer Rheinland(Jahresmitteltemperatur: 9,5 °C) sechs Soja-Sorten, und auf dem Versuchsgut der Universität Kassel-Witzenhausen, der Domäne Frankenhausen (nördlich von Kassel;...

Ekologisk slaktkyckling på hemmaproducerat foder och bete efter nöt
Provedor de dados: 21
Trots att konventionell kycklinguppfödning idag på många håll inte är överensstämmande med idéerna bakom ekologisk djurhållning (t.ex. benproblem och cikulationsrubbningar, preventiv medicinering, ingredienser till foderrationen och året-runt uppfödning inomhus), finns det fortfarande knappast någon ekologisk kycklinguppfödning i Sverige. Projektet syftar till att bidra till att utveckla ett ekologisk system för svensk kycklinguppfödning. Områden som behandlas är:   - Komposition av ett hemmaproducerat foder, inkl. experiment med konservering av proteinkällor som mjölk eller ägg som kycklingfoder.   - Test av långsamväxande raser.   - Kycklingarnas effekt på betet.   - Betets potentiella bidrag till kycklingarnas näringsförsörjning.

Autores: Link, Wolfgang.
Vicia faba L., die Ackerbohne, ist eine Körner-Leguminose wie Erbse, Lupine, Linse, Kicher-erbse, Phaseolus-Bohne und Sojabohne.  Aufgrund von BSE und wegen verbreiteter Skepsis gegenüber Soja erfahren heimische Eiweißfrüchte wie die Ackerbohne eine neue Aufmerksamkeit. Ackerbohnen werden in Deutschland und seinen Nachbarländern als Sommerform angebaut. Winterformen der Ackerbohnen sind in England im Anbau; in Deutschland sind die Winter zu kalt. Sommerbohnen werden häufig - wenn man wegen Frühjahres-Nässe nicht früher kann - zu spät gesät. Diese Schwierigkeit kann mit einer Herbstsaat vermieden werden.  Winterbohnen blühen und reifen früher, sind weniger von Sommertrockenheit betroffen, werden früher geerntet; dies gibt Zeit für Bodenbearbeitung nach...

Influence of probiotics and feed on organic rainbow trout health
Provedor de dados: 21
The aim of OPTIFISH is to optimize growth and survival for organic cultured rainbow trout, the dominant fish species produced in Denmark. A minor part of the rainbow trout is produced as organic fish. Currently there is no production of organic fry, as the classification organic only can be given to fish that have been treated with antibiotics no more than twice in a lifetime.  This is hard to achieve as recurrent disease outbreaks, especially with the bacterium Flavobacterium psychrophilum, are seen during the fry stage. A further challenge known from salmon culture is that diets with high plant contents cause enteritis and injury to the intestine, which will affect the absorption of nutrients, affecting the overall health status and welfare of the fish....

Differences in novel traits between genetic groups of dairy cows in pasture-based production systems
Provedor de dados: 21
Autores: Brügemann, Kerstin; Jaeger, Maria; Ruebesam, Karin; König von Borstel, Uta; König, Sven.
Breeding goals of Holstein dairy cattle in New Zealand (NZL) focus on traits reflecting adaptation to pasture-based systems. Due to high prices for concentrates, and advantages for cattle health and welfare, low input grazing systems become important in regions of North-West Germany. The present study addresses the hypothesis that progeny of NZL-Holstein sires are superior in 30 German grassland farms compared to offspring of Holstein sires being progeny tested in German indoor systems. A research design was implemented to create three different genetic groups (F1 generation) within herds on the basis of a German Holstein cow (GHC) population: Group 1=GHC x NZL sires, group 2=GHC x GH sires, group 3=GHC x GH_pasture sires.

Etablering er en af de mest omkostningskrævende processer i frøgræsproduktionen. Derfor vil flere års frøavl på samme udlæg reducere dyrkningsomkostningerne, såfremt frøudbyttet kan opretholdes på et højt/acceptabelt niveau. I andre frøproducerende lande gennemføres græsfrøproduktionen fortrinsvis på rækker, og der høstes frø på samme udlæg i betydelig flere år, end det er praksis i Danmark.

Pest and disease management in organic farming: implications and inspirations for plant breeding
Provedor de dados: 21
Autores: Döring, Thomas F.; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
The co-evolution of plants with their pests and diseases is a major driving force in evolution in nature. As a consequence, many pests and pathogens have multiple functions involved in survival on host populations. As a result of this continuous co-evolution, plant pests and pathogens have been selected for high reproduction rates, because of the low probability of an individual being able to find or infect a compatible host plant. For their part, host plants in natural ecosystems are often interspersed among other plant species and show wide and changing variation among individuals for genes affecting specific or non-specific resistance to each of the many pathogens that may attack them. Throughout the plant world there are dynamic and unstable equilibria...

Introduktion av kväveeffektivitet, ogräskonkurrens och allelopati i förädlingsmaterial av korn och vete med inriktning på ekologisk odling
Provedor de dados: 21
Sortmaterialet för ekologisk odling skiljer sig från sortmateialet för konentionell odling främst i två egenskaper; stor ogräskonkurrensförmåga och stort kväveutnyttjande. Projektet syftar därför till att göra direkta selektioner på dessa egenskaper i de konventionella förädlingsprogrammen för vete och korn. Selekterade genotyper kommer sedan att utvärderas i ekologiska försök. Selektionen görs i första hand på en ökad rottillväxt vilket i ett inledande projekt påvisats ge både stort kväveutnyttjande och stor ogräskonkurrensförmåga, det senare främst beroende på att genotyper med snabb tillväxt väljs i selektionen baserad på rottillväxt. För att ytterligare förbättra konkurrensförmågan avser vi även att identifiera genotyper med stor allelopatisk förmåga,...

Varieties of field vegetables and potatoes for organic production and marketing (continuation of OF0304)
Provedor de dados: 21
Description  The main objective of the work is to investigate the suitability of selected varieties of vegetables and potatoes for organic production. The organic vegetable market has increased rapidly over recent years and is continuing to increase in size. Market specifications are also continually tightening. Organic growing of vegetables and potatoes imposes severe restrictions on the treatments which growers can apply to crops to maximise yield and maintain quality while conforming to organic standards. Hence choice of variety is more critical in organic situations than for conventional crops where problems can be solved at a later date by application of pesticides or fertilisers. Varieties are needed that can respond to the conditions organic systems...

Das Forschungsvorhaben 2-Org-Cows sollte aufzeigen, dass auch in bedrohten Rassen zielgerichtete Zuchtarbeit und somit eine Verbesserung der funktionalen Merkmale (Parasitenresistenz, Eutergesundheit, Wiederkäu-, Fress-, Schlaf-, Aktivitäts-Verhalten) möglich ist. Eine effiziente Züchtung impliziert die Durchführung einer Zuchtwertschätzung im BLUP-Tiermodell. Zuchtwertschätzung wiederum ist nur möglich, wenn für die jeweiligen Merkmale hinreichende Erblichkeiten, insbesondere genetische Varianzen, vorliegen. Wesentlich war somit die Installation des Sensorsystems, welches durch eine Vielzahl wiederholter Messungen die Schätzung genetischer Parameter für neue Verhaltensmerkmale ermöglichte. In der doch kleinen Population der bedrohten DSN zeigte sich, dass...

Fertility and fertility management in thirteen well-established organic dairy herds in the UK
Provedor de dados: 21
Autores: Hovi, Malla; Taylor, Nick; Hanks, James; Roderick, Stephen.
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  Milk production and breeding records from thirteen organic dairy herds were collected between January 1997 and December 1999. Mean lactation yields in the herds ranged from 5127 kg to 7031 kg. Whilst seasonality of calving varied widely between herds, a majority of them (6/13) were autumn calving. Mean calving to first service interval was 80 days (range 68 to 97), and mean calving interval was 385 days (range 370 to 413). The mean number of services per conception was 2.3 (range 1.6 to 3.1). Overall culling rates and culling rates for fertility related problems were at 15.8% and 5.4%, respectively. A preliminary study of selected breeding...

The results show that thousand grain weight, protein content of seed, seed  contamination with fungi and seed emergence influenced yield potential of organically  produced seeds of spring barley in variety trials under organic farming conditions  during three years. Certified organic seed on average had smaller grains, lower  protein content and brought 5% less yield than conventionally produced seeds of the  same variety offered for trials by breeders. Different susceptibilities of the seeds for  contamination with fungi influenced the ranking of varieties and seed lots additionally.  The more of the previos seed quality parameters reached acceptable levels during  organic seed production, the better starting point for a better yield was obtained. The...

Cereal variety and population selection
Provedor de dados: 21
Autores: Jones, Hannah.
This research review notes that cereal variety breeding in the last 50 years has been based on pedigree line bred varieties as part of the development of a production system dependent on oil-based inputs. The characteristics desirable for an organic system are frequently at odds with those designed for non-organic systems. Despite this, varietal choice for organic farmers remains largely from the pool of varieties developed for non-organic production. The challenges to address are on what basis can farmers and advisers select varieties, and how to develop varieties suitable for organic production. Plant characteristics are discussed and main desirable features outlined under the headings of:   • Nutrient use efficiency  • Disease resistance  • Weed...

Autores: Hildermann, Isabell; Messmer, Monika; Kunz, Peter; Pregitzer, Anjana; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
Winterweizensorten mit Eignung für den Biolandbau müssen an sehr variable Umweltbedingungen angepasst sein. Möglichkeiten, diese Bedingungen in biologischen Anbausystemen zu kontrollieren, sind stark begrenzt, da die Nährstoffzufuhr limitiert ist und keine chemisch synthetischen Pflanzenschutzmittel und leichtlöslichen Mineraldünger eingesetzt werden. Die Züchtungsziele für den Biolandbau weichen teilweise deutlich von den Zielen für den konventionellen Anbau ab. Von besonderer Bedeutung im Biolandbau sind Bestockungsvermögen, Regenerationsfähigkeit nach mechanischer Unkrautbekämpfung, rasche Nährstoffaufnahme, Unkrautunterdrückungsvermögen, Pflanzenhöhe und Resistenz oder mindestens Toleranz gegenüber Blatt- vor allem aber Ährenkrankheiten, ein gut...

Breeding is an important tool to develop varieties with an optimal adaptation to organic farming. Several important traits are not covered by conventional research and breeding. At the State Plant Breeding Institute we are presently working on (1) resistance of rye to ergot (Claviceps purpurea), (2) nitrogen(N)-use efficiency in triticale, and (3) protein content of sunflower. The inheritance of these complex traits is quantitative. They are analysed in replicated field experiments at two locations in three years at several organic farms in Germany. For testing ergot resistance in rye, 68 populations, 250 full-sib families, 64 lines, and their 90 testcrosses were inoculated at mid-flowering by a spore suspension.

Significance of seed-borne Ascochyta on pea and test of management strategies
Provedor de dados: 21
Autores: Wolffhechel, H.; Bødker, L.; Nielsen, G.C.
Large amounts of Danish pea seeds are rejected each year due to high levels of Ascochyta infections. Selection of less susceptible pea varieties may reduce seed infections, while intercropping with barley only gives a small reduction. Increasing seeding rates has no effect. Short pea varieties generally seem to be more susceptible to seed infection by Ascochyta than taller varieties.

Virulence pattern in Danish races of common bunt (Tilletia  caries) Common Bunt
Provedor de dados: 21
Autores: Borgen, Anders.
By harvesting fungal spores from partly resistant varieties (as is the practise in normal organic seed production and farming), virulent races of common bunt builds up to devastating levels. The experiment shows that virulence against rare resistance genes to common bunt might be more frequent than expected, since European resistance screening so far have been done without preselecting of virulent races.

According to EU-Regulation 889/2008 slow growing strains shall be used in organic farming in order to ensure good broiler welfare. We examined effects of growth speed on broiler welfare in four different strains (33.01±5.8 to 44.02±8.0 g/day) in two batches on nine organic farms that kept two to four strains in parallel. The currently common slow growing strain (44.02±8.0 g/day) was a reference on all farms. In total 5593 broilers in 36 groups with 30 to 565 animals were kept. Live weight, lameness, skin and plumage condition and cleanliness of plumage were investigated on samples of 30 to 81 birds depending on group size. If possible, measures were taken repeat-edly (twice), at an average body weight of 1800 g to 2600 g. Individual data were analyzed...

This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and...

Alternative Oxidase (AOX) Senses Stress Levels to Coordinate Auxin-Induced Reprogramming From Seed Germination to Somatic Embryogenesis—A Role Relevant for Seed Vigor Prediction and Plant Robustness
Provedor de dados: 21

Somatic embryogenesis (SE) is the most striking and prominent example of plant plasticity upon severe stress. Inducing immature carrot seeds perform SE as substitute to germination by auxin treatment can be seen as switch between stress levels associated to morphophysiological plasticity. This experimental system is highly powerful to explore stress response factors that mediate the metabolic switch between cell and tissue identities. Developmental plasticity per se is an emerging trait for in vitro systems and crop improvement. It is supposed to underlie multi-stress tolerance. High plasticity can protect plants throughout life cycles against variable abiotic and biotic conditions. We provide proof of concepts for the existing hypothesis that alternative...

Leaf stripe resistance of spring barley cultivars
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.
Results of six years of screening trials clearly indicate that effective resistance against barley leaf stripe is available, also in modern cultivars. Among the spring barley cultivars that are currently most widely grown in Denmark, Cabaret, Troon, Sebastian, Justina and Brazil appear most resistant, but only Brazil combines a favourable resistance performance (= low mean and standard deviation of environment-adjusted leaf stripe incidence) with a high number of observations (= years of testing). However, the cultivars appearing most resistant over the years are relatively old ones such as Vada, Alabama, Odin and particularly Scarlett, which has been resistant in all years in which it was tested. Amongst the new cultivars, Marigold, Native and SW Immer...

Low level impurities in imported wheat are a likely source of feral transgenic oilseed rape (Brassica napus L.) in Switzerland
Provedor de dados: 21
Autores: Schulze, Juerg; Brodmann, Peter; Oehen, Bernadette; Bagutti, Claudia.
In Switzerland, the cultivation of genetically modified (GM) oilseed rape (Brassica napus L.) and the use of its seeds for food and feed are not permitted. Nevertheless, the GM oilseed rape events GT73, MS8×RF3, MS8 and RF3 have recently been found in the Rhine port of Basel, Switzerland. The sources of GM oilseed rape seeds have been unknown. The main agricultural good being imported at the Rhine port of Basel is wheat and from 2010 to 2013, 19 % of all Swiss wheat imports originated from Canada. As over 90 % of all oilseed rape grown in Canada is GM, we hypothesised that imports of Canadian wheat may contain low level impurities of GM oilseed rape. Therefore, waste fraction samples gathered during the mechanical cleaning of Canadian wheat from two Swiss...

The impact of seeding time was tested for hybrid rye in a yearlong field trial in Upper Bavaria. The rye (one variety) was seeded with the same sowing density at the end of  September and at the mid of October, respectively.  The impact of seeding time could be observed year-round: the mass growth before and after winter was obviously reduced by late sowing in comparison to usual seeding time. The results were lower plant height and clearly lower plant density in the variant late seeding time. Finally, the yield in the variant with usual seeding time was 27 % higher than by late sowing. Otherwise, the crude protein content, the falling number and the thousand seed weight were higher by late sowing. All in all, late sowing of hybrid rye may not be...

Assessment of disease in low-input cereal cropping systems and variety trials
Provedor de dados: 21
Autores: Hovmøller, M.S.; Pinnschmidt, H.; Willas, J.; Østergård, H.
Disease assessment is the basis for describing disease resistance characteristics of commercial varieties in national variety lists for all crops where disease is considered a problem. It is well known that ‘disease’ in a specific situation depends on a whole range of interacting hosts, pathogens and environmental conditions. However, the biological complexity conflicts with the wish to express disease resistance characteristics of a variety as a single score per disease. This problem will be illustrated by basic dynamics of growth and senescence of both host and pathogen over time. Disease expressed in terms of absolute diseased leaf area, disease relative to total leaf area or green leaf area will be discussed in general. Two particular problems in...

In general, the characteristics of organic varieties - and by extension of organic plant breeding - differ from that of conventional breeding systems and conventional varieties. Realising an organic plant breeding system and subsequently steering it to meet changing demands is no less than a mammoth task. The many actions to be undertaken can be divided into short-term commercial and scientific activities, and longer or long-term commercial and scientific activities.    Action must be taken in the short-term to ensure adequate quantities of organically propagated plants and seed. This is vital in consideration of Regulation 2092/91/EC which states that, as of 1 January 2000, all propagating material used in organic production must be of organic origin....

Ethics of Plant Breeding: The IFOAM Basic Principles as a Guide for the Evolution of Organic Plant Breeding
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.
When it comes to discussions on genetically modified organisms (GMOs) and organic agriculture, biotechnologists often ask: “Why are your rules so strict? Why ban GMOs when they are the only tool to secure the world’s future need for food? They are more efficient, quicker, etc!”  When asked these questions I explain the underlying values of organic agriculture. In this article I will discuss the basic values of organic agriculture as laid down in the IFOAM four basic principles, and will relate them to the field of plant breeding. I also discuss the consequences and challenges for the further development of organic plant breeding.

At present, around 95% of organic production is based on crop varieties that were bred for the conventional high-input sector, lacking important traits required under organic and low-input production conditions. Populations with a high level of genetic diversity are promising for OA (organic agriculture) conditions due to their adaptation, resilience and performance stability in different environments. Organic farming will benefit from cultivars (populations, varieties) that can cope with multiple stresses such as weeds, diseases, pests, climate change and low nitrogen input from manure. In the COBRA project (Coordinating Organic Plant Breeding Activities for diversity), plant genetic diversity and its potential have been investigated from both an...

Anbaueignung alter versus moderner Braugerstensorten im ökologischen Landbau
Provedor de dados: 21
Autores: Cais, Kathrin; Herz, Markus; Urbatzka, Peer.
Im ökologischen Landbau sind beim Anbau moderner Braugersten Kompromisse aufgrund z. B. einer kurzen bis sehr kurzen Pflanzenlänge nötig. In einem zweijährigen Feldversuch, auf je vier bayerischen Standorten, wurden daher drei alte Braugersten im Vergleich zu dem aktuellen Braugerstensortiment hinsichtlich ihrer Anbaueignung für den ökologischen Landbau geprüft.  Alle modernen Sortenerzielten im Vergleich zu den drei alten Sorten mit einer Ausnahme höhere Erträge und zeichneten sich durch wesentlich bessere Brauqualitäten aus. Zwar wiesen zwei der drei alten Sorten die im ökologischen Landbau gewünschten Eigenschaften einer größeren Pflanzenlänge und höher Massenbildung in der Anfangsentwicklung als die modernen Braugersten auf: ein geringerer...

Genetisk variation af rødder og rodhår mellem sorter af vårhvede
Provedor de dados: 21
Autores: Wang, Yaosheng; Thorup-Kristensen, Kristian; Jensen, Lars Stoumann; Magid, Jakob.
Rodsystemer er vigtige for planters optagelse af vand og næringsstoffer og dermed for vækst og ud-bytte, specielt under forhold med lav tilgæn- gelighed af jordens næringsstoffer. I det økologiske RDD projekt RoCo har vi undersøgt rodvækst, rodfordeling og roddybde samt rodhårs- karakteristika for forskellige sorter af vårhvede. Resultaterne af vores forsøg viser, at der er en stor variation i rod- og rodhårskarakteristika mellem forskellige vårhvedesorter, og disse er afgørende for, samt gene- tisk relateret til, afgrødens vækst og optagelse af næringsstoffer. Derfor er vital rodvækst og lange og tætte rodhår vigtige mål for selektion og fremtidig forædling af vårhvede til økologisk jordbrug.

Breeding for mycorrhizal symbiosis: focus on disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Messmer, Monika.
Modern plant breeding can no longer afford to ignore the interaction between plants and microbial key players. Increasing evidence suggests (i) that the expression of many plant traits (such as nutrient use efficiency or tolerances against biotic and abiotic stresses) is mediated by beneficial microorganisms and (ii) that there is an exploitable genetic base for the regulation of symbiotic relationships. Arbuscular mycorrhizal fungi (AMF) play a key role in many of these trait expressions. While much is known about their ability to mobilise nutrients (especially phosphorus), the complex mechanisms of AMF-mediated disease resistance have only started to become apparent within the past decade. Besides competition for root space and resources, AMF also have...

Final Report: Coordinating Organic Breeding Activities for Diversity - COBRA
Provedor de dados: 21
Autores: Pearce, Bruce.
Plant breeding is crucial in creating organic crop production systems that can better cope with interacting stresses such as pests and diseases (especially seed-borne diseases), weeds and the increasingly erratic and unpredictable variation in climate and weather. In this context, COBRA aimed to support and develop organic plant breeding and seed production with a focus on increasing the use and potential of plant material with high genetic diversity in cereals (wheat and barley) and grain legumes (pea and faba bean), through coordinating, linking and expanding existing breeding and research. Although systems based on high, within-crop diversity have shown promising results in organic systems and are now subject to intensive research, their benefits cannot...

Kann man von einer speziell biologisch-dynamischen Rindviehzucht sprechen? Eine Grundlage und zugleich ein Ziel biologisch-dynamischer Arbeit ist ein Umgang mit den Tieren und Pflanzen, mit dem Boden und der Landschaft, welcher diesen Lebewesen und Lebensräumen in ihrer Charakteristik und ihrer Eigenart gerecht wird und sie fördert. Nicht wirtschaftliche oder arbeitstechnische Überlegungen stehen im Vordergrund, sondern das Tier selbst, die Pflanzenart selbst, die Bodenart oder die Landschaft selbst; der landwirtschaftliche Organismus selbst. Es geht darum, in erster Linie diese Wesen zu verstehen und daraus abzuleiten, wie idealerweise mit ihnen umzugehen ist und in zweiter Linie, diese Ideale möglichst wirtschaftlich und möglichst machbar umzusetzen.

Konstitution und arttypische Eigenschaften. Beurteilung der Konstitution von Milchkühen anhand der Ausprägung ihrer wesentlichen arttypischen Eigenschaften
Provedor de dados: 21
Autores: Spengler Neff, Anet.
Jahrzehntelang wurden Milchrinderrassen fast ausschließlich leistungsorientiert gezüchtet. Das hat weltweit zu immer kürzeren Lebenszeiten und immer höheren Krankheitsanfälligkeiten der Tiere geführt, denn Gesundheitsmerkmale sind mit Produktionsmerkmalen negativ korreliert (LOTTHAMMER, 1999). Deshalb sind Zuchtverbände auf der ganzen Welt bestrebt, auch Gesundheitsmerkmale in die Zuchtwertschätzungen einzubeziehen. Für eine Zucht auf bessere Gesundheit wird neben der Erfassung von Krankheitsdaten der Tiere (v.a. in Skandinavien) nach einzelnen Hilfsmerkmalen wie Milchinhaltsstoffe, Exterieurmerkmale, Stoffwechselstabilität oder Fruchtbarkeitsdaten gesucht. Die Gesamtkonstitution der Tiere wird nur bei einer Zucht auf Lebensleistung (Haiger, 2001) wirklich...

Saflor als neue Ölpflanze im ökologischen Landbau - Zuchtmethodische Grundlagen und Schnellmethoden zur Qualitätsbestimmung
Provedor de dados: 21
Autores: Rudolphi, S.; Becker, H.C.; von Witzke-Ehbrecht, S.
In Deutschland werden Ölpflanzen nur auf etwa 2% der ökologisch bewirtschafteten Fläche kultiviert, wobei eine große Nachfrage nach ökologisch erzeugtem Pflanzenöl existiert. Der Saflor (Färberdistel) könnte als neue Ölpflanze für den ökologischen Anbau geeignet sein, da Distelöl als wertvolles Speiseöl sehr geschätzt wird.  Der Anbau von Saflor ist auch in Deutschland in sommerwarmen und -trockenen Regionen durchaus möglich. Es mangelt jedoch an Genotypen, die an das deutsche Klima angepasst sind. Besonders der niedrige Ölgehalt und die hohe Krankheitsanfälligkeit (vor allem Köpfchenfäule und Alternaria-Blattflecken) sind problematisch. Ziel des Vorhabens war es, methodische Grundlagen der Saflorzüchtung zu untersuchen und ein Konzept für die Züchtung...

Autores: Renaud, E.N.C; Lammerts van Bueren, E.T.; Paulo, M.J.; Eeuwijk, F.A.; Juvik, J.A.; Hutton, M.G.; Myers, J. R.
To determine if present commercial broccoli cultivars meet the diverse needs of organic management systems, such as adaptation to low N input, mechanical weed management, and no chemical pesticide use, and to propose the selection environments for crop improvement for organic production, we compared horticultural trait performance of 23 broccoli cultivars (G) under two management (M) systems (organic and conventional) in two regions of the United States (Oregon and Maine), including spring and fall trials. In our trials, location and season had the largest effect on broccoli head weight, with Oregon outperforming Maine, and fall trials outperforming spring plantings. M main effects and G × M interactions were often small, but G × M × E (location and...

Le pouvoir de compétition des variétés de blé face aux adventices: un critère de sélection important en Agriculture Biologique
Provedor de dados: 21
Autores: Neuhoff, Daniel; Eisele, J. A.
Le contrôle des mauvaises herbes en culture céréalière nécessite une rotation raisonnée mais également une bonne gestion de la lutte mécanique. De ce point de vue, la manière la plus efficace pour contrôler les mauvaises herbes est l’usage de la bineuse. Pratiquement, cette méthode est désavantageuse car elle nécessite de larges interlignes (plus de 17 cm) et un rythme de travail réduit. L’étrille par contre est moins efficace mais implique moins de contraintes techniques. Soulignons que ces deux méthodes dépendent largement des conditions météorologiques et sont coûteuses (temps, carburant, machines).  Une méthode indirecte permettant de contrôler les adventices consiste dans l’augmentation du pouvoir de compétition de la plante cultivée face aux...

A cow type for concentrate-free feeding systems - What characteristics does it display?
Provedor de dados: 21
Autores: Holinger, Mirjam.
Feeding of concentrates to ruminants in organic farming in Switzerland is questionable due to several aspects: (i) suitability for ruminants, (ii) land use change caused by soy cultivation, (ii) organic principles of closed circuits, and (iv) ethical considerations when ruminants directly compete with human nutrition.  In the past decades breeding strategies in the dairy sector focused primarily on milk production which led to increased energy requirements. A reduction of concentrates in the ration may thus lead to a more negative energy balance and may be detrimental for health and fertility. Published genotype x feeding system interactions suggest that different breeds, strains or genotypes react differently to different levels of feeding. The aim of...

Outcrossing rate of safflower (Carthamus tinctorius L.) genotypes under the agro climatic conditions of Northern Germany
Provedor de dados: 21
Autores: Rudolphi, Sabine; Becker, Heiko C.; von Witzke-Ehbrecht, Sabine.
Safflower oil is considered to be one of the highest quality vegetable oils for human nutrition, containing up to 90% linoleic acid. The cultivation of safflower would enlarge the number of species to increase biodiversity and widen crop rotation. Very little effort on safflower breeding has been done in Germany. The knowledge of the pollination system is a prerequisite of efficiently designing future breeding programmes. The cross pollination rate between and within plots was investigated in Göttingen (Latitude: 51° 32' North and Longitude: 9° 57' East ) in 2004 and 2005. A plot of 10 m2 of non-spiny plants was surrounded by plots of spiny plants. Ten nonspiny plants each of the border rows and of the core were harvested individually. The rate of cross...

Extract from attached abstract:  ... results from the present study do not justify general utilization of HF sires from NZL to improve productivity and functional traits in grassland systems in Germany. Heterogeneous results were found with e.g. advantages for NZL_HF regarding health composites of feet and legs, but in contrast impaired udder health. The broad pool of German Holstein sires should be used to select specific sires for distinct environments and breeding goals, e.g. HF_DEU_P for grassland systems. Furthermore, the present study revealed genetic background for traits that are generally related to cattle husbandry and farm management, e.g. the welfare indicator THS.

Approaches for field assessment of resistance to leaf pathogens in spring barley  varieties
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Hovmøller, M.S.; Østergård, H.
The resistance of spring barley varieties to powdery mildew, leaf rust, leaf scald and net blotch was characterized by using results from inoculated small-plot nurseries and larger survey plots subject to natural infection. The experiments were conducted in different environments. Both trial types often yielded complementary results with respect to the ranking of varieties suggesting that a recommended variety characterization should include both naturally infected survey-type trials and nursery trials in which the most relevant pathogen isolates and/or isolate mixtures or populations are used for inoculation. Average and median values of the diseased leaf area of a variety were highly correlated with each other and with the genotype main effect determined...

Plant breeding for organic and sustainable, low-input agriculture: dealing with genotypeenvironment interactions. Book of Abstracts
Provedor de dados: 21
This proceedings summarize the results of the  first EUCARPIA symposium on Organic Plant Breeding - Plant breeding for organic and sustainable, low-input agriculture: dealing with genotype-environment interactions - that took place in Wageningen in November 2007. EUCARPIA is the European Association for Research on Plant Breeding.     One of the major constraints in organic farming is that farmers still largely depend on crop varieties produced for conventional farming systems with high inputs of artificial, mineral fertilisers and chemicals for crop defence. Therefore, the organic sector urgently requires breeding programmes for robust varieties, which are better adapted to low-input conditions, with traits such as improved root systems, stronger...

Phosphorus Uptake in Six Selected Scandinavian Wheat and Barley Cultivars at Low Soil Phosphorus Availability as Related to Root Hair Length
Provedor de dados: 21
Autores: Holten, Jon Magne.
Lower soil phosphorus (P) levels are to be expected if more sustainable agriculture practices (organic farming, low-input farming) are adopted. Crop plants can be adapted to lower soil P levels by selecting and breeding for higher P efficiency. Longer root hairs are found to enhance the P efficiency of cereals by increasing the P uptake.     In this study, three pairs of Swedish and Norwegian cereal cultivars (wheat cvs. NK0058 and Diamant; 6-row barley cvs. NK94682 and Herse; 2-row barley cvs. Tyra and Herta), with respectively short and long root hairs within each pair as measured in solution culture were grown. The cultivars were grown at four soil P levels (P0: 35 mg P-AL kg-1 soil; P16: 49 mg; P32: 87 mg; P48: 130 mg) in a long-term PK fertilisation...

Genetics and welfare in organic poultry production. Genetics and welfare in organic poultry production  A discussion on the suitability of available breeds and hybrids
Provedor de dados: 21
Autores: Brunberg, Emma; Grøva, Lise; Serikstad, Grete Lene.
Organic production of eggs, broilers and turkey is regulated by international and national regulations and differs from conventional production. Breeds and hybrids selected for conventional production are also used in organic production. Many traits that are important for animal welfare are affected both by environment and genetics. This report gives an overview of the research about how animals with different genetics can be more or less suitable for alternative production systems. Moreover, the answers from a questionnaire among Norwegian poultry producers are reported. Possibilities for the development of animals more suitable for the goals and regulations in organic production are discussed.

An ancient compound rediscovered: perspectives of aphid control in organic hop growing by the use of quassia products
Provedor de dados: 21
Autores: Weihrauch, Florian; Eckert, Markus; Engelhard, Bernhard.
In the first three decades of the 20th century, quassia extract was widely used in hop growing as a chemical agent to control Phorodon humuli and other insect pests. In the first years of the 21st century this compound was rediscovered by German organic hop growers. In nine efficacy trials conducted in five field seasons, quassia products proved to be effective control agents for P. humuli in organically grown aroma cultivars. As the best method of application a systemic variant was developed by painting a suspension of quassia extract to the bines. This method proved not only to be very effective but was also best from an environmental point of view as sprayed quassia extracts had side effects on non-target organisms. As an optimal systemic application...

Hestebønner - sortsvalg og etablering
Provedor de dados: 21
Autores: Schou, Anders.
Skal økologer dyrke hestebønner? Det er der delte meninger om, særligt blandt de avlere der har forsøgt sig med afgrøden. Risikoen ved dyrkning er større end ved korn, men hvis håndværket er i orden kan en række af udfordringerne afhjælpes. Tørke, lus og chokoladeplet er desværre ikke noget økologer er herre over, og derfor er hestebønner en afgrøde der i værste fald mislykkes helt, men i de bedste år giver hestebønner mellem 4-5 tons pr. ha. Usikkerheden i udbytte opvejes i nogen grad af de fordele, som dyrkning af hestebønner giver i sædskiftet.

Approaches and achievements of biodynamic vegetable breeding by Kultursaat e.V. (Germany) using the example of RODELIKA one of the first certified biodynamic varieties
Provedor de dados: 21
Autores: Fleck, M.
Since 1998 RODELIKA is officially registered as a newly bred carrot variety. It had been developed by positive mass-selection over a 13 year period, based on an old-established variety within a farm based biodynamic system. The goal was a fine root with good health and a focus on taste and ability of maturation. Thus a selection-scheme in organoleptic characteristics sweetness and aroma was created. Numerous investigations demonstrate the very high inner quality of RODELIKA. Property rights of this open-pollinated variety are held by the charitable association Kultursaat eV as a common heritage.

Field Simulation of Transgenic Seed Admixture Dispersion in Maize with a Blue Kernel Color Marker
Provedor de dados: 21
Autores: Dietiker, Dominique; Oehen, Bernadette; Ochsenbein, Christian; Westgate, Mark E.; Stamp, Peter.
Seed purity in maize (Zea mays L.) has been almost neglected in coexistence studies. In this study, the impact of initial seed admixture was assessed in 20 fields (17 integrated pest management [IPM] and three organics) in the Swiss Midlands in 2007 and 2008 and a seed admixture threshold was proposed. The bluekernelled French hybrid Adonis was used as a color-marker admixture. In 2009, its pollen production was assessed relative to those of two commercial hybrids (LG 32.12 and DKC 2960) that released 41 and 62%, respectively, less pollen than Adonis. Adonis was added to commercial yellow hybrid seeds at a proportion of 1:99. On average, the seed admixture at harvest was 2.8 times greater than the seed admixture at sowing. The greater pollen production of...

Differences between spring wheat cultivars in susceptibility to Fusarium caused seedling blight
Provedor de dados: 21
Autores: Timmermans, Dr. B.G.H.; Osman, Ir. A.M.
Fusarium spp. present on spring wheat seeds can infect seedlings and cause reduced plant densities and higher wheat infestations. In the current project, variation between commercially available spring wheat cultivars in their tolerance to Fusarium seedling blight was investigated in a pot and a field trail. Additionally, initial growth rates of cultivars were measured to investigate possible relations with tolerance. Preliminary analysis shows presence of  tolerance differences between the spring wheat cultivars in the pot and field experiment. This difference was relatively robust (experiment x cultivar interaction was not significant). Preliminary analysis also showed a relation between tolerance and initial growth rates of cultivars in the field...

Production of high quality organic vegetable seeds encounters several challenges. Research is performed to support seed companies in producing vigorous and healthy organic vegetable seeds. Examples are provided with respect to research on seed vigour, determining critical control points to avoid disease transmission to the seeds, seed treatments with natu-ral compounds, new seed sorting techniques and enhancement of the natural plant defence. It is noticed that the restrictions in EU regulation 2092/91 on organic production are at present blocking the use of promising natural and sustainable components for seed treatments.

Autores: Haase, Thorsten; Quendt, Ulrich; Mindermann, Anke; Müller, Karl-Josef; Heß, Jürgen.
In 2010 two field experiments were set up and conducted under conditions of organic farming on two locations (clay loam and loamy sand) examining a set of winter pea genotypes (F7 generation crosses of winter and spring peas) for their winter hardiness, in the field and in a frost chamber under controlled conditions. The results from the first experimental season show no distinct correlation between flower colour and winter hardiness (survival rate). At the same time the marked range of survival rates within crossing groups and within leaf type x flower colour combinations confirm the relevance of further selection.

Autores: Arncken, Christine; Dierauer, Hansueli.
Zusammenfassung  Der vorliegende Bericht möchte am Beispiel des Roggens Informationen und Argumente für die Diskussion bereitstellen, ob Hybridsorten mit den Prinzipien des biologischen Landbaus vereinbar sind oder nicht. Während sich bei Mais und Gemüse Hybridsorten im biologischen Landbau schon ohne eine grundsätzliche Entscheidungsfindung eingebürgert haben, ist in der Schweiz beim Getreide eine grundsätzliche Meinungsbildung und Entscheidung noch möglich. Dies betrifft aktuell vor allem den Roggen.  Hybridsorten entstehen aus einer gelenkten Kreuzung zweier verschiedener reinerbiger Zuchtlinien, deren gemeinsame Nachkommen die Eltern im Ertrag übertreffen. Sie sind im Nachbau nicht genetisch stabil, das Saatgut muss daher jedes Jahr neu zugekauft...

Wie jede andere Leguminose, kann auch die Sojabohne (Glycine max (L.) Merr.) mit Hilfe von Soja-spezifischen Knöllchenbakterien (Bradyrhizobium japonicum) Luft-Stickstoff binden. Da die Bradyrhizobien natürlicherweise nicht in den mitteleuropäischen Böden vorkommen, müssen die Samen der Sojabohne mit kommerziell verfügbaren Bradyrhizobien-Impfpräparaten inokuliert werden. Beim Anbau hat sich in den letzten Jahren jedoch gezeigt, dass die Inokulation vor allem in kühleren Klimaten bei einzelnen Präparaten zu unzuverlässiger Knöllchenbildung und damit ungenügender Stickstoffbindung führen kann. Ziel dieser Arbeit ist es, die Eignung kommerziell verfügbarer Bradyrhizobien-Impfpräparate zur Inokulation der Sojabohne zu prüfen.

Autores: Schärer, Hansjakob; Mahlberg, Nicole; Tamm, Lucius; Koller, Martin.
To grow carrots in organic quality for storage is often difficult due to seed- and  soilborne diseases. In a series of experiments, seed treatments were evaluated to  improve seed health, field stand establishment and yield of carrots under field  conditions on farmer’s fields within their production system. In standard germination  tests in the laboratory, positive effects of the treatments were observable. However, in  subsequent field experiments, none of the tested seed treatments improved crop  establishment or yield. These results indicate that the quality of organic carrot seeds is  generally sufficient and improvements with farm-made seed treatments are difficult to  obtain. Further improvement in organic production of carrots may be achieved by...

Autores: Lammerts van Bueren, E.T.
Organic production and also the attention for plant breeding for organic agriculture is still increasing in Europe.  The question often raised is how much does plant breeding for the organic sector differ from modern plant breeding and does a ban on GMO also include refraining from molecular marker assisted selection (MAS)? In this paper I will first elaborate on the values in organic agriculture and it related systems approach as a central focus in organic agriculture and will then discuss in which way molecular marker assisted selection can be of use for plant breeding for organic and low-input agriculture.

For this purpose, we analyzed test-day records (July 1, 2011, to June 30, 2014) and treatment records (Austria, Sweden) of cows managed on organic farms. We performed country-wise comparisons of 123,415 lactations from Original Braunvieh (OB) and Grey Cattle (AL) with Braunvieh (BV; Brown Swiss blood &gt;60%) in Switzerland; AL with BV (Brown Swiss blood &gt;50%) in Austria; Polish Black and White (ZB), Polish Red and White (ZR), and Polish Red (RP) with Polish Holstein Friesian (PHF) in Poland; and Swedish Red...

Resistant barley varieties may facilitate control of Ramularia leaf spot
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Sindberg, Susanne A.; Willas, Jakob.
Ramularia leaf spot (RLS) is widely present in Denmark nowadays and has the potential to reach severity levels high enough to cause economic damage. The results of multi-location surveys and field trials of several years suggest that varietal resistance can be an efficient means for controlling RLS. The spring barley cultivars most affected by RLS possess mlo-resistance against powdery mildew while the least affected ones do not. Other mildew resistances as well as varietal susceptibility to other foliar diseases were not clearly related to the RLS reaction pattern of neither spring- nor winter barley cultivars. Promising RLS resistance donors may be the spring barleys Power, Helium, Isabella, Nathalie, Cruiser and Isotta and the winter barleys Lonni,...

Yield performance in heritage spring wheat and barley varieties in organic farming
Provedor de dados: 21
Autores: Borgen, Anders; Grupe, Per; Ytting, Nanna Karkov.
The grain yield in cereals has increased considerable since the beginning of industrialisation of agriculture, including introduction of modern plant breeding 100-150 years ago. Since beginning of this period, plant breeding has selected and bred varieties suitable to the changing agricultural conditions, and hence to increasing extent focused on conventional high input agriculture as this type of agriculture developed. Most pronounced is probably the plant height, and old high plants are likely to lodge at the nitrogen level normally seen in modern industrial agriculture. Modern varieties are characterised by a high degree of specific resistance genes against selected pathogens on the expense on a broad durable polygenic resistance (Robinson 1995)....

Development of Near-Infrared Reflectance Spectroscopy to Estimate Oil Content in Safflower
Provedor de dados: 21
Autores: Rudolphi, S.; von Witzke-Ehbrecht, S.; Becker, H.C.
The oil of safflower (Carthamus tinctorius L.) is a valuable oil for human nutrition. It contains a high amount of unsaturated fatty acids, in particular linoleic acid (up to 90 %).  There is a great demand for ecologically produced oil in Germany, though oil crops are cultivated on 2 % of the ecological acreage.  In Germany, hardly any variety test exists, moreover there has been no breeding efforts so far, although genetic variation in safflower is large. The aim of this study was the development of a rapid and non-destructive method to determine oil content in safflower seed using NIRS (Near-Infrared Reflectance Spectroscopy).  A total of 203 seed samples were scanned with NIRS to estimate the oil content. Intact seeds as well as milled seeds were...

Three Composite Cross Populations (CCPs) of winter wheat were created in 2001, one from crossing high baking quality parents (called QCCP), one based on high yielding parents (YCCP), and one created from both parent sets combined (YQ). All three CCPs were grown for several years in the UK and in Germany under conventional and organic cropping management. Based on properties of the different parent sets, yields were predicted to be highest in the YCCP and lowest in the QCCP, with the YQCCP in between. However, data showed that the YCCP was not significantly higher-yielding than the more generalist YQCCP in five out of six sites; in fact, the YQCCP even tended to outyield the YCCP on average over all sites, and this effect was significant at the German...

Increasing yield instability due to climate change could be mitigated by higher interand intra crop diversity. During the course of the INSUSFAR project, several questions  regarding the impact of more diverse crops on agricultural systems are adressed. To answer these questions, varieties, mixtures, and composite cross populations of wheat will be investigated in field experiments and on-farm. Based on the results, the socio-economic, ecological and yield  performance of these varieties and the extent of  genetic changes in genetically diverse populations will be tested. In addition, effects of plant breeding on the adaption of varieties to different input levels will be analysed.

In Australia and New Zealand the formulation of breeding values for GIN resistance led to large selection programs in sheep successfully improving genetic resistance to GIN. Compared to sheep, the progress with respect to breeding for GIN resistance for various reasons has been much slower in goats. Data on heritabilities of potential auxiliary traits for selection and knowledge about their genetic correlation to production traits is limited. The present Swiss study was designed to fill this gap.  A total of 1.500 goats (20 flocks) of the Alpine and Saanen breed were enrolled in the study. They were individually phenotyped twice for faecal egg count (FEC), FEC of Haemonchus (HCFEC; using fluorescin based differentiation of eggs), FAMACHA eye scores and...

Contribution of feeds from range in organic broiler production
Provedor de dados: 21
Autores: Steenfeldt, S.; Horsted, K.; Sørensen, P.
A study with organic broilers with access to a large range area with herbs was performed and the effect of three broiler genotype (JA757, T851, SU51) with different growth rates and different feeding strategies (HP vs LP) on the animals' feed intake, growth and welfare was investigated. The results so far indicate that feed intake from range and animal welfare is dependent on type of allocated feed and growth rate of the broiler genotype. Thus, gait scores and foot and plumage condition showed that the fastest growing broiler genotype had some problems when fed normal broiler feed, whereas this was not the case for the other genotypes. The fastest growing broilers also ate more pelleted broiler feed compared to the slower growing breeds, which in contrast...

Breeding for symbioses – Mycorrhizae as a case study
Provedor de dados: 21
Autores: Hohmann, Pierre; Backes, Gunter; Thonar, Cécile; Messmer, Monika.
Plant associated soil microbes are known to play an important role in the expression and stability of certain plant traits such as nutrient use efficiency and disease resistance. Arbuscular mycorrhizal fungi (AMF) form one of the primary mutualistic plant-microbe symbioses. Besides known benefits such as improved nutrient mobilisation (mainly phosphorus and zinc) and tolerance against abiotic stresses (mainly drought), an increasing number of studies highlight a significant role of AMF in the mediation of disease resistances and priming mechanisms. Individual reports have shown enhanced levels of defence-related compounds (such as glucanases, chitinases and phenolics) in mycorrhizal plants, and there is first evidence of certain phytohormone pathways (in...

Rye as an outcrossing crop is highly susceptible to ergot infection caused by Claviceps purpurea. It is ecologically the best solution to avoid the infection already in the field by growing resistant varieties. Aim of our study is the analysis of inheritance of self-fertile rye material for ergot resistance and alcaloid content. Sixty CMS inbred lines and their 90 CMS crosses were tested in pollen-isolated fields in three environ-ments under the conditions of Ecological Farming by artificial inoculation. The sclerotia weight per head was evaluated as resistance trait. Both, CMS lines and testcrosses showed significant genotypic differences at the individual environments. Correlation between both groups was significant (r=0,6-0,7; P=0,01). The alcaloid...

The choice of growing media and the strategy of  application of organic fertilizers is considered one of the largest challenges for production of organic tomato plantlets for transplanting. We have measured the growth and the ability of young tomato plantlets to extract plant nutrients from an organic growing media. Plants were grown in 0.45L pots. Plant nutrition were either entirely based on the mineral nutrients, available from the organic growing media or based on a combination of nutrients from the organic growing media and fertigation with water-soluble organic fertilizers during plantlet production. The first results shows that plant dry weigth and uptake of nitrogen, phosphorus and potassium was reduced in the organic growing media compared to the...

This is the final report of Defra project OF0154.  Under the European Union Regulation on the organic production of agricultural products (2092/91), crops raised in organic systems should be grown from organically produced seed or vegetative material. However, the supply of organic seed is limited in the UK and in Europe as a whole, and so by way of derogation, the EU Regulation permits the use of untreated, conventional seed on organic farms only when an appropriate organic variety cannot be sourced. At the start of this project, the derogation period was due to end on 31 December 2000; however, it was extended in June 1999 to 31 December 2003, after which the use of conventional seed will not be permitted on organic farms.

Development of locally-adapted faba bean cultivars for organic conditions in Germany through a participatory breeding approach
Provedor de dados: 21
Autores: Ghaouti, Linmiae; Vogt-Kaute, Werner; Link, Wolfgang.
Organic farming requires cultivars that are specifically adapted to this low input cropping system. Hence, organic farmers and scientists joined in a participatory breeding approach to develop region-specific genotypes of spring faba bean for organic conditions in Germany. A set of 49 genotypes with contrasting degrees of heterozygosity and heterogeneity was used in field trials across five locations in Germany during 3 years 2004, 2005 and 2006. The material involved 18 inbred lines, their 18 polycross progenies, one blend of inbred lines, one blend of polycross progenies, one blend of hybrids and ten checks. Inbred lines are uniform, thus giving the option to be specifically adapted; whereas the polycross progenies and synthetics (Syn-1; predicted from...

Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Organic farmers have become more interested in the marginally grown (neglected) cultivars, as spring forms of the hulled wheat varieties (eincorn, emmer wheat, spelta wheat) or intermediate forms of the soft wheat. 173 land races from the gene bank at the RI in Praha-Ruzyně were grown on the organic certified parcel and evaluated in 2008. The trial aimed to evaluate the conditions of the competitiveness to weeds, tolerance to diseases, assimilation of the sun shine and establishment of the yield. The results show that all the evaluated material inclines to the competitiveness to weeds. This ability is, nevertheless, reduced because of the inclination to the lodging (all the cultivars have long weak stalks). Eincorn and emmer wheat are resistant to mildew...

Prüfung neuer pilzwiderstandsfähiger Rotweinrebsorten auf ihre Anbaueignung in Franken
Provedor de dados: 21
Autores: Schwab, Arnold; Knott, Reiner.
Five new fungus-tolerant grape varieties were tested from 2005 to 2010 in comparison to Merlot in Franconia/Germany. Crossings with Cabernet Sauvignon showed different ripening behavior, and aroma expression. Cabernet Carbon presented a full-bodied wine, whereas Cabernet Coral ranged sensorically near his cross parent Cabernet Sauvignon. Reberger as a very early ripening variety reached often plumy notes. All 5 varieties are not totally fungus resistant and need some plant protection depending on the yearly infection conditions. In specific years the tested Cabernet crossings had problems with stem dieback and bunch rot. Cabernet Carol and Cabernet Cortis reached the best results in relation to Merlot.

Mastleistung von Bruderhähnen bei Fütterung mit unterschiedlichen Proteinquellen
Provedor de dados: 21
Autores: Ammer, Stefanie; Quander, Nele; Posch, Julia; Maurer, Veronika; Leiber, Florian.
In drei Mastversuchen wurden die Wachstumsleistungen männlicher Legehybriden bei Fütterung mit unterschiedlichen Proteinquellen und -gehalten untersucht. Der Vergleich der Genotypen Lohmann Braun (LB) und Lohmann Selected Leghorn (LSL) mit dem Masthybriden Hubbard JA 757 (HUB) zeigte, dass die Bruderhähne erwartungsgemäss geringere Mastleistungen aufwiesen. Sowohl die Lebendgewichte und täglichen Zunahmen als auch die Schlachtgewichte wurden vom Genotyp beeinflusst.  Die LB-Hähne wiesen jedoch deutliche Vorteile in den Leistungen gegenüber den LSL-Tieren auf. Der partielle Ersatz von Soja durch Luzernegrünmehl in den Rationen, der mit einer Proteinreduktion einhergeht, führte vor allem bei HUB zu Leistungseinbussen.  Im Gegensatz dazu konnten für den...

Højere udbytte i vårhvede og vårbyg
Provedor de dados: 21
Autores: Schou, Anders.
Vårhvede og vårbyg er hver for sig velkendte arter i det økologiske sædskifte, hvor vårhvede normalt dyrkes til konsum og vårbyg i stor udstrækning til foder. I sortsafprøvningerne lykkes det ofte, at opnå udbytter på over 50 hkg/ha, hvorimod udbyttet ude på bedrifterne ligger noget lavere. Særligt vårhvede ligger i praksis langt under 50 hkg/ha. I praksis er det derfor kun en mindre del af sorternes fulde udbyttepotentiale der udnyttes, hvorfor det er interessant at undersøge hvilke praktiske tiltag der kan hæve udbytterne.

Provedor de dados: 21
Autores: Blume, Steffen.
Arealet med vårbyg blev i 2012 større end antaget, hvilket skyldes udvintring af vinterhvede og gulrust i triticale. Og da såsæden af andre vårsædsarter hurtigt blev udsolgt, måtte mange økologer nøjes med vårbyg. Generelt har vårbyg landet over givet gennemsnitlige udbytter og har således været det rigtige valg i forhold til en udvintret vinterhvede.

Vliv genotypu a ustájení na složení mastných kyselin ve vaječném žloutku
Provedor de dados: 21
Autores: CHARVÁTOVÁ, Vladimíra; OKROUHLÁ, M.; ENGLMAIEROVÁ, Michaela; TŮMOVÁ, Eva.
Cílem této práce bylo porovnat vliv genotypu a systému ustájení nosnic na obsah a složení mastných kyselin ve vaječném žloutku. Do pokusu bylo zařazeno celkem 64 vajec dvou genotypů (hybrid Lohmann LSL a plemeno česká slepice) ustájených v klecích a na podestýlce. Z výsledků měření je patrné, že nejvyšší zastoupení nasycených, mononenasycených i polynenasycených mastných kyselin vykázalo plemeno česká slepice ustájené na podestýlce. Naopak nejnižší hodnoty byly zjištěny u hybrida Lohmann LSL chovaného na podestýlce. Genotyp nosnic měl průkazný vliv na obsah všech mastných kyselin a vliv systému ustájení byl průkazný jen u mastných kyselin C15:0, C20:4, C22:2 a PUFA (n-6/n-3). Interakce mezi genotypem a systémem ustájení byly průkazné pouze u mastných...

Within-crop genetic diversity increases temporal yield stability in organic winter wheat
Provedor de dados: 21
Autores: Fradgley, Nick; Howlett, Sally; Wolfe, Martin.
Organic farming aims at developing farming systems that do not need unsustainable inputs such as mineral fertilisers and pesticides to regulate the cropping environment.  Such systems need crop varieties that are resilient against multiple and variable biotic and abiotic stresses and that make efficient use of the nutrients and resources that are available.  Highly genetically diverse cereal Composite Cross Populations (CCPs) have been proposed as an approach to dealing with these stresses (Döring et al., 2011).    Field trials investigated the yield stability of two winter wheat CCPs compared to two respective mixtures of their parental varieties as well as high yielding (c.v. Alchemy) and high quality (c.v. Solstice) elite pure-line control varieties at...

Agronomic performances of self-reseeding legumes on alkaline soil under Mediterranean climate
Provedor de dados: 21
Autores: Ayoub, Dr. Mohamed.
Self-reseeding legumes are an essential component of the Mediterranean natural resources. Germplasms collected from the Mediterranean region were introduced in Australia and subjected to an extensive breeding. Species were then re-introduced in their original habitat where they were object of different important researches. Despite all the efforts made to select appropriate species and varieties, well-adapted cultivars have not been yet identified for all situations. At the experimental farm of the Mediterranean Agronomic Institute of Bari, Italy, agronomic performances of 15 cultivars of self reseeding legumes were compared on an alkaline soil to evaluate their possible use in organic agriculture systems. 10-m2 plots were used in a complete randomised...

Tick-borne fever in sheep - production loss and preventive measures
Provedor de dados: 21
Autores: Grøva, Lise.
A major challenge in sheep farming during the grazing season along the coast of south-western Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum, that is transmitted by the tick Ixodes ricinus. The justification for this study is based on our limited knowledge on the effect of A. phagocytophilum infection on indirect losses i.e. reduced weight gain and weaning weight in lambs. Further, there is a lack of efficient and sustainable preventive measures to tick-infestation and TBF which implies a need for new knowledge. Knowledge on the effect of age of lamb to a natural A. phagocytophilum infection and genetic variation in robustness to A. phagocytophilum infection are possible preventive measures that are investigated in this...

Noch bevor die Weizenernte anfängt, wird bereits das Saatgut für die Aussaat im Oktober bestellt. Die meisten Schweizer Biobauern wählen die Sorte Wiwa aus der Getreidezüchtung von Peter Kunz. In der Kategorie Mahlweizen von Bio Suisse (Top und gute 1. Klassweizen) erreichte Wiwa letztes Jahr einen Marktanteil von 52 Prozent. Das zeigt, dass die Biobauern mit der Sorte rundum zufrieden sind. Im Sinne der Sortenvielfalt sollte aber der Anteil nicht weiter zunehmen.

Optimierung der Saatgutgesundheit im ökologischen Arznei- und Gewürzpflanzenanbau
Provedor de dados: 21
Ein großes Problem im ökologischen Arznei- und Gewürzpflanzenanbau besteht darin, dass die Saatgutverfügbarkeit bis heute nur unzureichend ist und auch die Züchtungsarbeit bisher noch in den Anfängen steckt. So stehen kaum krankheitstolerante und -resistente Sorten aus ökologischer Vermehrung zur Verfügung. Einen Ausgleich für dieses Defizit soll die Verbesserung der Saatgutqualität bedeuten, denn geringe Keimfähigkeiten, schwache Triebkraft des Saatgutes und pilzliche Schaderreger führen zu verzögertem, lückigem Feldaufgang und späterem Erkranken der Bestände. Ziel des Projektes ist daher, die Saatgutqualität durch praxisrelevante Strategien wie Saatgutbehandlungsmethoden und pflanzenbauliche Maßnahmen (Saatgutaufbereitung) zu verbessern und gesundes,...

In this empirical study interviews with experts from different business like organic agriculture (OA) or plant breeding companies were conducted to analyze the possibilities and limits of new plant breeding techniques (NBT) for organic agriculture (OA). Furthermore, the consequences of banning the NBT in OA were investigated. The survey showed that these techniques offer beyond some limits also opportunities for OA. Before excluding these techniques a priori, it seems to be rational to decide case by case depending on the cultured traits if these techniques are suitable for OA.

Autores: Rahmann, Gerold.
Im ökologischen Landbau und in der Biotoppflege handelt es sich um eine In-situ-Haltung mit einem züchterischen Fortschritt gegenüber der Ex-situ-Haltung z.B. in zoologischen Gärten oder privaten Rassezüchtern. Beiden Formen kommt eine wichtige Rolle in der Art- und Rassenerhalten landwirtschaftlicher Nutztiere zu, sie ist jedoch nur als Notlösung akzeptabel. Züchterische Arbeit in Hinblick auf Arten- und Rassenvielfalt landwirtschaftlicher Nutztiere muß sich an den neuen Funktionen  und Leistungserwartungen orientieren. Dies ist nicht nur ethisch sondern auch ökonomisch sinnvoll und erforderlich.

Characteristics of spring barley varieties and crop diversity for  organic farming and variety testing
Provedor de dados: 21
Autores: Østergård, H.; Jensen, J.W.
Results from Danish spring barley variety trials including about 50-120 varieties and variety mixtures on three locations over three years under organic as well as conventional farming systems demonstrate the importance of genotype-environment interactions. This has implications for potential future organic VCU-testing; here results are shown for grain yield. Further, grain yield results from of six variety mixtures and their 14 component varieties indicate that variety mixtures may be less influenced by genotype-environment interactions compared to pure line varieties.

Auf dem Weg zu einer ökologischen Tierzucht
Provedor de dados: 21
Autores: Schmidt, Gernot.
Welche Rinder, Schweine, Hühner braucht der ökologisch wirtschaftende Betrieb? Welche geeigneten Rassen stehen zur Verfügung, und welche Ansätze gibt es, um Tiere mit den gewünschten Eigenschaften zu züchten? Welche Strukturen müssen dazu aufgebaut werden?    Um diese Fragen geht es in einem von der Zukunftsstiftung Landwirtschaft organisierten und im Rahmen des Bundesprogramms Ökologischer Landbau geförderten Projekt. Mit ihm sollen die Aktivitäten für eine ökologische Tierzucht ermittelt, vernetzt, die Notwendigkeit des Aufbaus eigenständiger Strukturen geprüft und Zuchtverbände und Zuchtunternehmen für eine Öko-Züchtung gewonnen werden.    Der Text stellt bisher gewonnene Ergebnisse des laufenden Projektes vor.    Inhalt:    Ökologische Rinderzucht: Von...

The use of organic propagation material is obligatory according to the current EU regulations for organic production. However, frequently difficulties are en-countered regarding the availability, the costs or the quality. In the Netherlands a national research program aims at developing solutions, needed for improving the production of high quality organic propagation material. The main emphasis in the pro-gram is on the model crops cabbage, onion, wheat and potato. Individual projects within the program include epidemiological studies of seed borne dis-eases to develop disease prevention strategies, meth-ods to improve resistance of seeds and seedlings towards pathogens and methods to control silver scurf in seed potatoes, development of multi-spectral...

Performance and selection of winter durum wheat genotypes  in different European conventional and organic fields
Provedor de dados: 21
Autores: Mikó, P.; Vida, G.; Rakszegi, M.; Lafferty, J.; Lorentz, B.; Longin, F.; Megyeri, M.
Sustainability is a key factor for the future of agriculture. Productivity in agriculture has more than tripled in developed countries since the 1950s. Beyond the success of plant breeding, the increased use of inorganic fertilizers, application of pesticides, and spread of irrigation also contributed to this success. However, impressive yield increases started to decline in the 1980s because of the lack of sustainability. One of the most beneficial ways to increase sustainability is organic agriculture. In such agro-ecosystem-based holistic production systems the prerequisite of successful farming is the availability of crop genotypes that perform well. However, selection of winter durum wheat for sub-optimal growing conditions is still mainly neglected,...

Der Einfluss veränderter genetischer Korrelationen auf den  Selektionserfolg bei Selektion mit einem Ökologischen  Gesamtzuchtwert
Provedor de dados: 21
Autores: Krogmeier, Dieter; Herold, Pera; Postler, Günter; Steinwidder, Andreas.
Genetic correlations between milk yield and different fitness traits were estimated in Fleckvieh and Brown Swiss cattle. These updated correlations were taken into  account in the calculation of an organic total merit index (ÖZW), where the fitness traits have larger weight than in the conventional total merit index (GZW). As a  consequence, the relative theoretical selection response in functional traits (18-23%) was higher and the selection response in milk yield was lower than before. This index  is therefore more suited for the ecological breeders but may also implicate that biological and conventional breeding goals will drift apart. To ensure that in the long term suitable bulls for biological farms will be available, AI  stations will have to...

Multi-purpose cowpea inoculation for improved yields in small holder farms in Kenya
Provedor de dados: 21
Autores: Mathu, Samuel; Thonar, Cécile; Vanlauwe, Bernard; Messmer, Monika; Frossard, Emmanuel.
Introduction  In Kenya, cowpea is the most important pulse crop in the dry lands of Eastern and Coastal regions where it is commonly inter cropped with maize and sorghum.  The poor yields obtained in small holder farms in Kenya (150 kg ha-1) can in part be attributed to the use of poor yielding varieties, low soil fertility (mainly N and P deficiency) low presence of effective indigenous rhizobia and high occurrence of highly competitive but inefficient indigenous rhizobia strains.  Biological nitrogen fixation (BNF) through exploitation of the rhizobia-legume symbiosis and use of inoculants coupled with soil amendments such as Phosphorus offers in part a means to improve cowpea yield, nutrition and soil fertility.

Autores: Dierauer, Hansueli.
Avant même que le blé soit moissonné, il est déjà possible de commander la semence pour les semis d’octobre 2018. La plupart des paysans bio de Suisse cultivent le blé Wiwa, issu de la sélection variétale de Peter Kunz. Dans la catégorie « Blé panifiable biologique Bourgeon CH », qui comprend les blés Top et les meilleurs blés de la classe 1, Wiwa a représenté l’année dernière une part de marché de 52 %. Cela indique que les paysans bio sont très satisfaits de cette variété. Mais une diversité variétale suffisante doit se maintenir, et donc la part de Wiwa ne devrait pas augmenter davantage.

Suitability of different dairy cow types for an Alpine organic and low-input milk production system
Provedor de dados: 21
Autores: Horn, Marco; Steinwidder, Andreas; Gasteiner, Johann; Podstatzky, Leopold; Haiger, Alfred; Zollitsch, Werner.
The  implementation of  a  seasonal, site adapted, pasture-based milk production system as applied in New Zealand and North Western Europe might be an alternative for the near future in  Alpine regions. As in such a  low-input system the fertility and secondary traits such as robustness  against  metabolic  challenges  of   dairy cows  is   of   crucial  importance,   it  is questionable whether conventional dairy cow types, which were selected primarily for  milk production under high-input conditions, are most suitable. Therefore the aim of this study was to compare two different genotypes concerning their suitability for an organic, low-input milk production system under  Alpine  conditions.  Between  2008  and  2011 records  from 91 lactations of Brown...

Resistance against Fusarium spp. in narrowed leafed lupin (Lupinus angustifolius L.)
Provedor de dados: 21
Autores: Jørnsgård, Bjarne; Kuptsov, Vladislav; Jensen, Birgit; Bødker, Lars; Knudsen, Jens Christian; Nielsen, John.
L. angustifolius genotypes susceptible to Fusarium root rot and wilt can be grown in new lupin land without disease symptoms, however, lupin root rot and wilt pathogens build up during repeated cropping of susceptible lupins in the same field. After four lupin crops symptoms of root rot and wilt began in an inhomogeneous pattern over the field, and after another three lupin crops susceptible lupins are destroyed before flowering homogeneously over the field and caused total crop failure. The dominating pathogens isolated from diseased lupins with root rot and wilt symptoms in this field are in descending order F. oxisporum, F. solani, F. culmorum,  and F. avenaceum, the latter only being isolated from young autumn sown plants.

Breeding Goals for Organic Dairy Farming in Denmark Based on the Principles of Organic Agriculture
Provedor de dados: 21
Autores: Slagboom, Margot; Wallenbeck, Anna; Rydhmer, Lotta; Thomasen, Jørn Rind; Kargo, Morten.
Organic dairy farming (ODF) is different from conventional dairy farming in management practices, but so far the same breeding goal (BG) is used, based on the same economic models (EM). However, ODF is based on the principles of organic agriculture defined by the IFOAM, which are not easily interpreted in economic terms and it may be  uestionable to use a BG for ODF based on EM. In this study we set up three BGs for ODF in Denmark, one based on the  principles of organic agriculture, one focusing on roughage consumption and feed efficiency, and one focusing on disease resistance. A questionnaire and desired gains index were used to set up the BGs. Correlations between these BGs and BGs based on EM were low. Which BG would be best suitable to use for ODF in...

Forage cuts as a by-product in organic seed production
Provedor de dados: 21
Autores: Deleuran, L.C.; Boelt, B.
A major problem in organic grass seed production on arable farms is to provide for a sufficient nitrogen supply. A nitrogen-fixing crop may be able to cover the nitrogen requirement - wholly or partly. However mixed cropping of a grass seed and a nitrogen-fixing crop is expected to reduce the establishment of the seed crop, especially for species that require a long establishment period. One way to achieve a satisfactory establishment of the seed crop can be to introduce an intervening year for cutting forage between cover crop harvest and seed harvest. This will enhance tillering, since the light supply for the undersown grass is increased after each cut. However excessive biomass will hinder drying of the crop at maturity and therefore the growth of the...

What breeding strategy(ies) should be carry up for organic winter wheat? Results and prospects from a long-term comparison with low input variety trials
Provedor de dados: 21
Autores: Le Campion, A.; Oury, F. X.; Morlais, J.Y.; Walczak, P.; Gardet, O.; Gilles, S.; Pichard, A.; Rolland, Bernard.
Breeding varieties adapted to various organic farming conditions is one solution, among others, to increase yields and improve organic winter bread wheat quality. From 2004 to 2011, INRA winter wheat breeders have conducted variety trials in three contrasting agro-climatic regions across north-west France to test the relative response of 25 to 30 diversified genotypes when cultivated in low input (FI) and organic (AB) conditions. The comparison of 17 paired management trials showed the relevance of low input conditions to identify genotypes adapted to organic farming conditions for yield and protein content. Such a selection environment is useful also to screen “GPD+” (positive Grain Protein Deviation) genotypes with better nutrient use efficiency. In...

Because of the interdiction of chemical seed treatment, smut resistance is a main demand for cultivation of winter barley in organic farming. A comparison of common high yielding varieties with those chosen particularly with regard to good smut-resistance or tolerance showed no significant differences in field performance under the conditions of organic farming. Main criteria were the yield of grain and the content of protein and most important amino acids for animal nutrition (Cystine, Lysine, Me-thionine, Threonine, Tryptophan). Besides this the degree of shading weeds was estimated by means of measuring leaf areas and lengths of stalks. The leaf area proved to be the main factor. The availability of smut resistant or tolerant varieties out of organic...

Hardy varieties in competition with weeds for sustainable agriculture and especially organic farming
Provedor de dados: 21
Autores: FONTAINE, L.; BERNICOT, M.-H.; ROLLAND, B.; POIRET, L.
A three-year programme was begun in 2007 to develop a method for assessing the competitive potential of wheat varieties with respect to weeds and to encourage the adoption of this criterion in selection programmes. The first year of experiments made it possible to identify the most explanatory characteristics of the competitive potential of wheat (using Italian ryegrass to simulate weeds): height first, followed by ground cover and leaf habit. These factors are nevertheless not adequate for totally predicting the competitive potential of wheat varieties and, in particular, intermediate varieties for which wide variations were observed from one situation to another in our experiments. We are now waiting for the results of two additional years of experiments.

Does Thule III have resistance gene Bt-13?
Provedor de dados: 21
Autores: Borgen, Anders.
All over the world, Thule III is used as differential variety for the resistance gene Bt-13 against common bunt. It can therefore be strange that I can question whether Thule III have Bt-13, so let me elaborate the question. I also use Thule III as a standard for Bt-13, and I got this variety from GRIN PI 181463. This variety does indeed have a major gene against common bunt and since we all use it as a standard for Bt-13 this gene is per definition Bt-13. What still puzzles me is that this variety does not look like Thule III. It says in the GRIN database that it is of Swedish origin with the pedigree Thule II/Sammet. PI 181463 is a short, lodging and weak variety with a very poor winter hardiness, and it does not at all look like a Swedish winter wheat....

„Das, was heute für uns normal ist, dass wir uns treffen und austauschen – das gab es früher nicht!“  Das Netzwerk Ökologische Tierzucht bringt seit 2002 die Pioniere und Experten zusammen, die sich in der Ökologischen Tierzucht engagieren. Das Netzwerk (2. Projektphase 2005-2007) arbeitet in Form von tierartbezogenen Arbeitsgruppen, die ihre Ergebnisse in Workshops diskutieren. Geleitet wurden die Fachgruppen von ausgewiesenen Experten; die Koordination übernahm die Zukunftsstiftung Landwirtschaft.   Tierzucht ist als Thema auf den Betrieben und bei den Beratern oftmals weit weg. Das Potenzial, das eine artgemäße Tierzucht gerade auch für die Tiergesundheit und damit auch für die ökonomische Situation bietet, wird nicht gesehen. Das Netzwerk kann hier...

Ergebnisse aus den Mahlweizen Streifen-Sortenversuchen 2014
Provedor de dados: 21
Autores: Dierauer, Hansueli; Klaiss, Matthias.
Winterweizen ist die bedeutendste Kultur im Bioanbau. Die Sortenwahl kann bezüglich Qualität und Ertrag entscheidend sein. Agroscope Reckenholz führt jedes Jahr Exaktversuche mit 16 Sorten auf 8 Standorten unter Biobedingungen durch. Die vielversprechendsten Sorten aus dieser Prüfung kommen in das Praxisversuchsnetz der Kantone, welches vom FiBL koordiniert und ausgewertet wird. Für die Durchführung, Bonituren und Ernten sind die kantonalen Bioberatungsstellen oder im Auftrag das FiBL zuständig.  Bevor eine Sorte in die empfohlene Sortenliste FiBL- Bio Suisse aufgenommen wird, muss sie drei Jahre in den Exaktversuchen und mindestens zwei Jahre im Praxisversuchsnetz geprüft sein.

ÉVALUATION DE LA SENSIBILITÉ AUX BIOAGRESSEURS DE 36 VARIÉTÉS DE POMMIERS DANS UN RÉSEAU DE PARCELLES BIOLOGIQUES À FAIBLES INTRANTS
Provedor de dados: 21

Les bioagresseurs sont une des principales limites à la production de pomme dans les systèmes conduits en AB et à faibles niveaux d’intrants. Une des clefs du contrôle des bioagresseurs dans ces vergers est le choix des variétés (Trapman et Jansonius, 2008). La variabilité de l’expression de la sensibilité variétale peut être appréhendée grâce à un réseau multi-site pluri-annuel.  Quatre parcelles de pommier biologique conduites de manière semi-extensive ont été plantées en 2002 afin d’identifier des variétés d’intérêts pour les systèmes à faible intrants. 36 variétés ont été suivies afin d’évaluer conjointement leur sensibilité à la tavelure, aux pucerons et à l’oïdium.La thématique de cette étude initiée en 2002 se trouve être au coeur des...

Vinterbyg som alternativ til triticale
Provedor de dados: 21
Autores: Hansen, Jesper.
Efter en årrække med gode erfaringer mht udbytte, afsætning og dyrkningssikkerhed i vintertriticale, var arealet i 2009 steget til ca. 5.900 ha. I 2010 faldt arealet til ca. 1.070 ha – et fald på over 80%. Dette skyldtes, at de sorter der blev anvendt i 2009 blev meget hårdt angrebet af gulrust. Resultatet af dette blev udbytter på helt ned til 500 kg/ha eller lavere - svarende til mellem 10 og 30% af normale udbytter. I 2011 steg arealet med ca. 800 ha til knap 1.900 ha, da udbuddet af gulrustresistente triticalesorter steg. I efteråret 2011 blev arealet igen øget, efter nogle fine udbytter og intet eller kun meget lave angreb af gulrust i 2011.

Parts of the herds of several pasture-based dairy farms mainly located in North-western Germany are inseminated with two strains of Holstein-Friesian genetics (New Zealand vs. others) for a comparison of traits reflecting health and welfare. Daughters of NZ bulls tend to be less dirty, healthier with regard to feet and legs, and less sensitive to losses in body condition. Further investigations will include cow and herd specific factors as a basis for comparisons including economically important production and functional traits of ongoing lactations and generations.

Importance of appropriate selection environments for breeding maize adapted to organic farming systems
Provedor de dados: 21
Autores: Messmer, Monika M.; Burger, Henriette; Schmidt, Walter; Geiger, Hartwig H.
Organic farming systems, characterized by special attention to soil fertility, recycling techniques and low external inputs, gained increased significance in recent years. As a consequence, there is a growing demand for varieties adapted to organic and/or low input farming. The objectives of the present study were to (i) compare the testcross performance of segregating maize (Zea mays) populations under established organic (OF) and conventional farming (CF) systems, (ii) determine quantitative genetic parameters decisive for the selection response under OF vs CF conditions, and (iii) draw conclusions for breeding new varieties optimally adapted to OF. Testcross performance of four different material groups of preselected lines (90 lines per group) derived...

Milchziegen auf Biobetrieben in Deutschland  [Dairy goat keeping in organic farming in Germany]
Provedor de dados: 21
Autores: Nina, Hesse; Christian, Krutzinna; Gerold, Rahmann.
Die Geschichte der Milchziegenhaltung in Deutschland ist durch starke Gegensätze sowohl in der Einstellung zum Tier Ziege, als auch in der Entwicklung der Ziegenbestände geprägt. Während die Milchziege in früheren Zeiten allgemein geschätzt wurde, erhielt sie ca. ab dem 17. Jahrhundert unter anderem den Ruf als Waldschädling. Als „Kuh des kleinen (armen) Mannes“ werden nach dem ersten Weltkrieg rund 4,5 Mio. Milchziegen gehalten. Im Vergleich dazu hat die Milchziegenhaltung heute mit 125.000 Ziegen (Bundesstatistik 1998) nur geringe Bedeutung in Deutschland (zum Vergleich: Griechenland 5,9 Mio., Spanien 2,5 Mio., Italien 1,4 Mio., Frankreich 1,1 Mio., Portugal 0,8 Mio., Niederlande 0,13 Mio.; Zahlen für 1998).

Breeding goats for organic production in Germany
Provedor de dados: 21
Autores: Rahmann, Gerold.
With only 120,000 females (year 2000), goat keeping is a niche activity in animal husbandry in Germany. Most of the goats (about 90%) are kept on part-time farms. The main reasons they are kept are as a hobby, for milk production and for landscape management; in many cases  it is a non-profit oriented activity. There are estimates (no official statistics exist) that 20,000 goats are milked and 10,000 are used in landscape management to avoid shrub succession on protected biotopes. In the year 2000 10% of the goats (12,000) were kept on organic farms but not all for economic reasons.    Because the dairy breeds in Germany (White and Brown German Alpine) are selected under intensive keeping conditions, breeding under the restrictions of organic farming is...

Konsekvenser ved sameksistens mellem økologisk raps og GM raps i Danmark
Provedor de dados: 21
Autores: Andersen, Naja Steen.
Inden for ganske få år forventes det, at GM sorter af raps vil blive dyrket i Dannmark. Raps er en af de danske afgrøder, der har det største potentiale for genspredning. Det er derfor nødvendigt at løse de sameksistensproblemer der vil opstå, når GM raps dyrkes i nærheden af økologisk raps og ikke-GM raps. I hvilken grad agerkål og spildraps og urenheder i certificeret rapsfrø bidrager til forekomsten af GM under forskellige forhold, undersøges i et igangværende projekt på Risø og KVL.

Weidebasierte Produktionssysteme haben in den letzten Jahren wieder einen Aufschwung in Deutschland erfahren. Diese Tendenz wird durch die in den öffentlichen und politischen Fokus gerückte Debatte um Tierwohl und Gesundheit in der Nutztierhaltung verstärkt. Immer mehr gewinnen dabei nicht nur Tierwohl-Indikatoren an Bedeutung, welche einen Rückschluss auf die Haltungsbedingungen erlauben, sondern auch Maßnahmen zur Reduktion und Prophylaxe krankheitsverursachender Erreger wird vermehrt Berücksichtigung geschenkt. Insbesondere Infektionen mit Endoparasiten wie Magen-Darm-Strongyliden (MDS), dem Rinderlungenwurm (Dictyocaulus viviparus), aber vor allem solche mit dem großen Leberegel (Fasciola hepatica), stellen bei Milchvieh in Weidehaltung ein...

Spike productivity in relation to yield as criterion for emmer wheat breeding
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan (Jr.); Moudry, Jan.
Landraces, which are unbred cereal species, and include in particular the tetraploid emmer wheat, have become an important focus for the activities of local or organic farmers, processors and consumers of organic products. This study is based on analyses of the spike productivity, harvest index and grain yield of six emmer wheat landraces. It aims to find suitable criteria for the selection of cultivars and varieties which may contribute to the increase in the productivity of the emmer wheat. The cultivars and varieties most commonly used have short dense spikes which have a negative effect on the grain yield, as the spike density is negatively correlated with the weight of thousand grains (TGW), the weight of the grains in the spikes, the number of grains...

Anfälligkeit für innere Parasiten bei Schaf und Ziege im Hinblick auf Rassen- und Herdenunterschiede
Provedor de dados: 21
Autores: Heckendorn, Felix.
Infektionen mit inneren Parasiten gehören weltweit zu den bedeutendsten Gesundheitsproblemen von Schafen und Ziegen. Insbesondere führt die Gruppe der Magen-Darm Strongyliden (MDS) zu beträchtlicher Morbidität und hohen ökonomischen Verlusten. Am Beispiel der englischen Schafzuchtindustrie wurde berechnet, dass die jährlichen durch MDS verursachten fi nanziellen Verluste über 103 Millionen Euro ausmachen (Nieuwhof und Bishop, 2005).  Seit den sechziger Jahren wurden MDS mit chemischsynthetischen Medikamenten (Anthelminthika) kontrolliert.

Mit Mikrobrötchen bessere Weizen finden
Provedor de dados: 21
Autores: Österle, N.; Müller, Karl-Josef.
The trade-value of organically grown wheat is mostly determined by the wet gluten content, the SDS-sedimentation value and the stirring number. Further information about wheat quality can be obtained through the rapid-mix test, however, both the rapid mix-test and laboratory parameters have been criticized for not displaying baking qualities adequately. In this study, 172 samples of organically grown wheat varieties and breeding lines were analyzed for their wet gluten content, SDS-sedimentation value, falling number and their performance in a baking test. A linear regression showed the highest correlation of the bread volume to the SDS-sedimentation value with R2=0,29. A multiple regression model explained 56% of the volume variation by the...

Hybrid Varieties for Organic Cereals? Prospects and acceptance of hybrid breeding for organic production
Provedor de dados: 21
Autores: Arncken, Christine; Dierauer, Hansueli.
Hybrid breeding utilizes the advantages characterizing F1 plants in a targeted manner: Vigour, uniformity, and a combination of all dominant traits of the parental lines. It gives breeders secure licences, as farmers can not save seed from hybrid varieties with a view to replanting.  Regarding rye, the current advantages of hybrid varieties are primarily the higher yields but also improved resistances to lodging and sprouting. However, farmers can only benefit from higher yields if the limited market for organic rye in Switzerland can be expanded. The currently available hybrid rye varieties have higher susceptibility to leaf rust and ergot infections.    The criticism of hybrid breeding and hybrid varieties concerns four areas:   Firstly, the area of...

Autores: Tiemens-Hulscher, Marjolein; Lammerts van Bueren, E.T.; Struik, Paul.
Zowel in de biologische als in de gangbare aardappelteelt is er behoefte aan rassen die met minder stikstof toe kunnen. In het biologische teeltsysteem is de hoeveelheid beschikbare stikstof vaak een beperkende factor. Zowel in de gangbare als de biologische teelt wordt er naar gestreefd om de stikstofgift te verminderen om verspilling en uitspoeling te voorkomen. Stikstofefficiëntie is een complexe eigenschap waar verschillende gewaseigenschappen aan bijdragen. In dit project werd onderzocht of er gewaseigenschappen zijn die gerelateerd zijn aan stikstofefficiëntie en waarop een veredelaar effectief kan selecteren. Stikstofefficiëntie werd daarbij gedefinieerd als het vermogen van een ras om bij een lage stikstofbeschikbaarheid, 100 -150 kg/ha, in een...

Die Fababohne (Vicia faba L.) ist als Körnerleguminose eine ‘low input’-Frucht, die gut zur ökologischen Landwirtschaft passt und die dem ökologischen Anbausystem eine Reihe von Vorteilen gibt (z.B. ‚break crop’, positive N-Bilanz, Unkraut-Unterdrückung). Der Einsatz von Chemikalien in der konventionellen Landwirtschaft mildert dort teilweise die Auswirkungen von Umweltschwankungen auf die Feldfrucht.  In der ökologischen Landwirtschaft ist es sehr wichtig, genetische Variation zu nutzen als Mittel, um mit den agro-ökologischen und umweltbedingten Schwankungen umzugehen, um das Risiko eines Anbau-Misserfolges zu vermindern.  Deswegen benötigt die ökologische Landwirtschaft Sorten, die besonders an die ökologischen Bedingungen angepasst sind.    Die...

Autores: Hildermann, Isabell; Messmer, Monika; Kunz, Peter; Pregitzer, Anjana; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
The possibilities to balance environmental conditions in organic farming systems are strongly restricted as the input of nutrients is limited and no soluble fertilisers and synthetic pestizides are used. These systems require cultivars that are able to adapt to stressful, less controlled and therefore highly variable environments. This study sums up the results of winter wheat cultivars tested under marginal and fertile soil conditions on organic farms in Switzerland. Three were derived from organic, three from conventional breeding programs and two old cultivars. Across three marginal sites, there was a slight trend towards higher yields of the organically bred cultivars. This difference was statistically signifi cant at the lowest yielding site. However,...

Efter 2010, hvor hovedparten af den økologisk dyrkede vintertriticale gik mere eller mindre til pga. gulrust, har arealet med vintertriticale siden ligget på et meget lavt nivaeu. I 2012 steg arealet dog lidt igen, efter man havde fundet nogle mindre modtagelige sorter - troede man. De blev dog ret hårdt angrebet af rust i det tidlige forår, og en del arealer blev derfor sået om. Det viste sig dog, at det ikke gik helt så galt som man frygtede. Min vurdering er, at angrebene højest kostede 10-20% i tabt udbytte.

Spring barley grain quality changes in conventional and organic growing conditions
Provedor de dados: 21
Autores: Kokare, A.; Legzdina, L.; Lammerts van Bueren, Edith T.
While breeding for organic farming it is necessary to identify the most appropriate  growing conditions in which to perform the selection process. Soil fertility, crop  management, yield level and other factors may vary very much between each organic  farm, and between organic farms and research institutions where the selection is usually  performed. Since plant breeding requires considerable input of resources and the market  for organic varieties is limited, it is essential to find the most appropriate selection  conditions that will provide acceptable varieties for organic farms.  Spring barley breeding lines selected from two cross combinations (Primus/Idumeja and  Anni/Dziugiai) at two distinctive organic and two conventional locations were used in...

Variations in the composition of the major elements of wheat varieties in industrial and organic farming systems: initial results
Provedor de dados: 21
Autores: PIQUET, A.; SAUVAT, S.; BRANLARD, G.
A nutritional analysis was added to the study of the characterization of wheat varieties in organic and industrial farming systems for the year 2005-2006. The experimental design consisted of three wheat varieties (Atrium, Ataro and Renan) and three densities (200, 400 and 600 grains/m2) on two soils representative of the Auvergne region. The parameters studied were productivity, technological suitability and nutritional value (N, P, K, Ca, Mg). The yield was particularly low for organic farming (23 q/ha), following unfavorable climatic conditions. In spite of the low yield under organic farming conditions, the Mg and P contents in the grains were normal. The low thousand-grain weight and the early maturity of Atrium did not make it possible to increase...

Ability of new durum wheat pure lines to meet yield stability and quality requirements in low input and organic systems
Provedor de dados: 21
Autores: Colomb, B.; Desclaux, D.; Debaeke, P.; Justes, E.; Burger, P.
Low-input production schemes adopted in organic or conventional farms require crop varieties that combine good product quality and high yield stability under non optimal environmental conditions (Gooding et al., 1999). These traits are not yet found among the durum wheat genotypes available in France. Consequently the cultivation of this crop is hardly successful in stockless organic farms in southern France, which are characterised by very low nitrogen resources. Some hopes emerged with the identification of new durum wheat pure lines with a high grain protein content in breeding experiments conducted near Montpellier in 2001 and 2002. The aim of the present work was to confirm and elucidate the origin of the enhanced protein performance of these new...

Organic substrate for transplant production in organic nurseries. A review
Provedor de dados: 21
Autores: Pascual, Jose Antonio; Ceglie, Francesco; Tuzel, Yuksel; Koller, Martin; Koren, Amnon; Hitchings, Roger; Tittarelli, Fabio.
A transplant can be defined as a seedling or sprouted vegetative propagation material grown in a substrate or in the field, for transfer to the final cropping site. Nurseries use a range of growing media in the production of transplants, and the quality of a substrate may be defined in terms of its feasibility for the intended use and also according to the climatic condition of the production site. Peat is the worldwide standard substrate, but because of its origin and the increasing environmental and ecological concerns, new alternatives have been proposed for organic production. Here, we reviewed these new alternatives, assuming that the proposed growing media will need to respond in a proper way to specific plant requirements while also taking them into...

The Effect of Spore Origin when Screening for Resistance against Common Bunt
Provedor de dados: 21
Autores: Borgen, Anders.
Screening wheat varieties for resistance against common bunt is often done by adding a uniform sample of spores to a number of wheat varieties. The spore sample is often maintained on a susceptible variety from year to year. The problem with this design is that there are no replicates of the spore sample. It is therefore not possible to conclude what would be the result if a different spore sample was used. A simple way to improve this system is in the second year of experiments to test the varieties with low infection levels with both the spore sample, and in addition to that to use spores of the same variety from previous years trial. Often, the use of spores from the same variety will result in a higher infection level than using spores from other...

In context of a larger project dealing with the traits of barley that are related to organic farming (BAR-OF), we performed an association mapping in order to dertermine the genetic loci linked with the respective traits. In two subsequent years (2002 and 2003), we used field results from 96 barley lines and varieties, partially overlapping between the years. The lines/varieties were grown on three Dansih locations (Flakkebjerg, Foulum and Jyndevad). For Foulum and Flakkebjerg, we observed both fields grown under organic and conventional regime; for Jyndevad only fields cultivated under organic conditions were ecploited. Neither in the organic nor in the conventional fields; diseases were controlled chemically. In the resulting five environments per year,...

Like other grain legumes, also field pea globally is important sources of plant protein and their growing have also positive effect on soil fertility. But, there are some constraints in their production, such pests and diseases and unstable yield. A high biodiversity and the selection of appropriate cultivars are important factors for the stability of agricultural systems especially in organic farming. Corresponding genotype choice for pea growing in mixtures with cereals can be one of the possibilities which enhances stable yield through field environment changes based on species diversity.

Crop mixtures consisting of cereals and legumes have proven as a well-adapted arrangement due to their complementarity towards important resources, especially nitrogen. Crop mixtures combine high yield performance and yield stability. They can contribute to a diversified cropping landscape and adaptation to climate change. The search for alternatives to protein imports from overseas and investments in post-harvest separation technologies are currently fostering their adoption by farmers in Western-Europe, especially under organic and lowinput  farming conditions. However, screening and breeding for mixed cropping has hardly been explored for arable crops. Thus, the objective was to develop novel breeding strategies and tools specifically for mixed cropping...

Als ausdauernde Pflanze entwickelt der perennierende Weizen ein ausgeprägtes Wurzelsystem, so dass die Pflanze mit Trockenzeiten und einem geringeren Nährstoffangebot besser zurechtkommt. Im Vordergrund des Projektes steht nicht die Ertragsmaximierung, sondern die Minimierung des Aufwandes sowie ökologische und naturschutzrechtliche Aspekte wie Reduzierung der Erosion. Der Anbau ist an drei Standorten vorgesehen, die sich hinsichtlich der Höhenlage, der...

Brug egen såsæd i økologisk jordbrug
Provedor de dados: 21
Autores: Borgen, Anders.
Der har i den danske landbrugspresse i sommeren 2008 været en debat om fordele og ulemper ved anvendelse af egen udsæd i forhold til anvendelse af certificeret udsæd. Landscenteret har eksempelvis beregnet, at konventionelle landmænd kan spare 265-350 kr/ha ved at bruge certificeret udsæd på 10% af markerne, og bruge egen såsæd på resten. Omvendt fremhæver såsædsbranchen for det første, at den danske model, hvor langt hovedparten af landmændene køber certificeret såsæd er med til at finansiere dansk planteforædling, og dermed til at vi har de bedste sorter, og for det andet et certificeret såsæd er af en bedre kvalitet bl.a. på grund af bejdsning. I økologisk landbrug er forholdene anderledes end i det konventionelle landbrug.

Saflor als neue Ölpflanze im ökologischen Landbau - Zuchtmethodische Grundlagen und Schnellmethoden zur Qualitätsbestimmung
Provedor de dados: 21
Autores: Rudolphi, S.; Becker, H.C.; von Witzke-Ehbrecht, S.
In Deutschland werden Ölpflanzen nur auf etwa 2% der ökologisch bewirtschafteten Fläche kultiviert, wobei eine große Nachfrage nach ökologisch erzeugtem Pflanzenöl existiert. Der Saflor (Färberdistel) könnte als neue Ölpflanze für den ökologischen Anbau geeignet sein, da Distelöl als wertvolles Speiseöl sehr geschätzt wird.  Der Anbau von Saflor ist auch in Deutschland in sommerwarmen und -trockenen Regionen durchaus möglich. Es mangelt jedoch an Genotypen, die an das deutsche Klima angepasst sind. Besonders der niedrige Ölgehalt und die hohe Krankheitsanfälligkeit (vor allem Köpfchenfäule und Alternaria-Blattflecken) sind problematisch. Ziel des Vorhabens war es, methodische Grundlagen der Saflorzüchtung zu untersuchen und ein Konzept für die Züchtung...

Differences between spring wheat cultivars for emergence and early development after seed infection with Fusarium culmorum
Provedor de dados: 21
Autores: Timmermans, B.G.H; Osman, A.M.
Infection of wheat seeds with Fusarium spp. causes seedling blight. As a result of this disease, fields sown with infected seeds show a reduced plant density. This is especially a problem in organic agriculture, for which currently no practical seed disinfection methods are available. In the present project we investigated whether spring wheat cultivars differ in sensitivity to seedling blight, whether the possible differences could be linked to cultivar differences in early growth rates, and what size the delay in canopy closure resulting from the plant reductions was. Six spring wheat cultivars (Melon, Lavett, SW Kungsjet, Epos, Pasteur, Thasos), containing three infection levels (averages 5, 15 and 27%) of Fusarium culmorum were obtained and were sown...

Organic seed production and seed regulation
Provedor de dados: 21
Autores: Borgen, Anders.
Organic farmers must use organic seed material if such seed are available. If not available, conventional seeds can be used. This request exists in all accredited standards for organic farming. In the EU-regulation on organic production methods, the derogation from the use of organic seed material will only exist until the end of 2003. After this date only organic seed material may be used according to the present formulation.    Only a few countries in the EU have an organic seed production able to supply the market for organic seed material. It takes many years to develop a well functioning market for organic seeds. It is therefore unlikely that the derogation for the use of organic seed material will not be extended, since a majority of countries in the...

Vårbygsorters resistens mod stribesyge og nøgenbrand
Provedor de dados: 21
Autores: Pinnschmidt, H.O.
ORGSEED undersøgelserne viser, at der findes en række vårbygsorter med lovende resistens overfor stribesyge og nøgenbrand. Under dyrkningsforhold, hvor de to sygdomme betragtes som nøgle-problemer, burde sortsvalget derfor tager hensyn til de resistensoplysninger, som ORGSEED projektet har tilvejebragt.     Men det skal huskes, at muligheden for at bruge sortsresistens ikke kommer af sig selv. Det kræver stadig årvågenhed med hensyn til at følge skift i sorternes sygdomsreaktion over tid og dette kræver fortløbende resistens-screening og –afprøvning af markedsførte sorter såvel som af forædlingsmaterialet.

Baking quality is a major problem of wheat production in organic farming in Germany. The main reason is low protein content, but also different gluten characteristics. The aim of our investigations was to verify, whether selection of varieties with special adaptation to organic farming (or OF systems with particular low input) is advantageous. 66 Genotypes of winter wheat (registered German varieties, breeding lines, older varieties and varieties bred for organic farming) were compared in 5 environments over two years. Yield, protein content and quality parameters were assessed. Aptitude to LI- or HI- conditions was determined using intravarietal linear regression. While selection for special adaptation proved to be superior for yield and protein yield,...

Selection of winter cereals for organic agriculture
Provedor de dados: 21
Autores: Mikó, P.; Megyeri, M.; Molnár-Lang, M.; Rakszegi, M.; Vida, G.
Productivity in agriculture has more than tripled in developed countries since the 1950s. Beyond the success of plant breeding, the increased use of inorganic fertilizers, application of pesticides, and spread of irrigation also contributed to this success. However, impressive yield increases started to decline in the 1980s because of the lack of sustainability.  One of the most beneficial ways to increase sustainability is organic agriculture. In such systems the prerequisite of successful farming is the availability of crop genotypes that perform well. However, selection of winter cereals for sub-optimal growing conditions is still neglected, and the organic seed market also lacks of information on credibly tested varieties suitable for organic...

Performance of wheat composite crosses on station and on-farm
Provedor de dados: 21
Autores: Finckh, Maria R.; Heinrich, Sven; Brumlop, Sarah.
The F11 of 14 winter wheat composite cross populations (CCPs) were compared in replicated field trials to the mixture of the 20 parents and three commercial wheat cultivars in replicated field trials. In addition, one population was given to farmers for on-farm testing. In 2012 severe frost killed 16 out of the 20 parental varieties of the CCPs. In contrast, the mixture of these varieties and the CCP populations survived well. The CCPs with high yielding parents yielded still highest in the F12 and quality in the CCPs with high quality parents was highest. CCPs on-farm were comparable in performance with farmers reference varieties.

Breeding for Mixed Cropping and Anthracnose Resistance of Lupins
Provedor de dados: 21
Autores: Arncken, Christine; Hohmann, Pierre; Messmer, Monika.
Introduction  In Switzerland, the organic sector has been trying to reduce the massive import of protein crops for feed by encouraging grain legume cultivation during the past years (Clerc et al, 2015). The main limiting factors of low yield stability and high weed pressure were successfully overcome through intercropping of peas and faba beans with barley and oats, respectively. Thus, the production of peas and faba beans grew continuously from 2010 to 2015 from 200t and 90t to 1170t and 560t, respectively (bioaktuell 2017). For more diversification of domestic grain legume cultivation and supply, FiBL has started field trials with blue (Lupinus angustifolius) and white lupins (L. albus) in 2014. The high risk of anthracnose, caused by the fungal agent...

Betydningen af vækstregulering, bestøvning og skadedyrsangreb (hvidkløversnudebillen Apion Flavipes) for udbytterne i økologisk hvidkløverfrøavl
Provedor de dados: 21
Autores: Grossmann, Cand. agro. Freya.
Grundet et nyt EU-direktiv skal alle økologiske landmænd i EU fra 2001 udelukkende anvende økologisk fremavlede frø.  Da Danmark er førende på området, og hvidkløver er den vigtigste afgrøde på de økologiske gårde, er der behov for at øge dyrkningen.    Der er imidlertid en række dyrkningsmæssige faktorer, der tilsammen er årsag til meget lave udbytter i de økologiske frømarker.    Denne opgave omhandler disse faktorer, med særlig vægt på at undersøge vækstregulering, bestøvning og angreb af hvidkløversnudebillens larvers betydning for frøudbyttet.  Faktorerne er analyseret ved litteraturstudie, og desuden blev der udtaget hvidkløverhoveder fra et parcelforsøg opstillet ved SJF-Flakkebjerg.     På baggrund af de hovedanalyser der blev foretaget, blev der...

Improved quality and disease management in diverse populations
Provedor de dados: 21
Autores: Borgen, Anders.
Improved biodiversity is one of the key principles in organic farming and therefore organic plant breeding seeks alternatives to the currently dominant pureline monocultures. Evolutionary plant breeding of composite cross populations (CCPs) has been proposed as a breeding tool for organic plant breeding, where a highly heterogeneous population of offspring is made by mixing a large number of segregating lines from different parents (Döring et al. 2011). Natural selection will, to some extent, reduce traits  onferring major disadvantages in a population if these have a high heritability and a significant impact on seed reproduction. It will not, however, necessarily improve baking quality, negative traits with a strong interaction with the environment or...

Organic dairy breeding lines? – Possibilities and Requirements
Provedor de dados: 21
Autores: Kargo, Morten; Thomasen, Jørn Rind; Wallenbeck, Anna; Hjortø, Line; Slagboom, Margot.
Genomic breeding schemes with large cow reference populations will give room for more line division within dairy cattle breeding and therefore also for organic breeding lines. The reason is that different economic values between organic and conventional production systems are expected in the future and the existence of genotype by environment interaction will presumably be even more recognized. Therefore, correlations between organic and conventional breeding goals are expected to be significantly lower than one. This in combination with increased future “break even” correlations opens up for specific organic breeding lines.

Improved welfare in sheep production.Preventive measures, disease resistance and robustness related to tick-borne fever in sheep
Provedor de dados: 21
The greatest welfare challenges for sheep during grazing are tick-borne fever (TBF), blow-flies, alveld and predators. Production losses on tick infested pastures are substantial, and it is expected that more than 300 000 lambs/sheep are affected by TBF. In sustainable farming, particularly organic farming, the focus on solving these challenges should be on preventive measures. The dependence on drugs implies a risk for developing resistance. It is therefore of general interest to use preventive methods. However, few efficient preventive measures against tick infection and TBF are available. Thus, there is a need for alternative strategies. The focus of the project will be on: Indirect losses The indirect loss caused by TBF is impaired welfare, growth...

Global betrachtet war die Steigerung der Erträge zur Bekämpfung von Hunger in den vergangenen Jahrzehnten das Hauptziel in der Weizenzüchtung (Triticum aestivum L). Mit der Einführung von Verzwergungsgenen wurde der Ernteindex verbessert, der das Verhältnis Kornertrag zur oberirdischen Gesamtbiomasse darstellt. Begleitet von einer ansteigenden Zufuhr von Stickstoff- (N) und Phosphor- (P) Düngern und der Anwendung von Pestiziden hat dies zu einem beträchtlichen Ertragszuwachs geführt. Durch die jahrzehntelange Züchtung auf Hochertragssorten für den intensiven Anbau wurde möglicherweise das optimale Düngungsniveau im Weizenanbau verschoben und so indirekt auf Sorten mit einem höheren Nährstoffbedarf selektiert.

Formal breeding methods were not always suitable to address the very large diversity of both environmental conditions and end-user needs. Both were frequently encountered either in marginal areas of developing countries or in organic farms of EEC. Participatory plant breeding (PPB) methods represent alternatives aimed to improve local adaptation breeding, to promote genetic diversity, to empower farmers and rural communities. The term  PPB refers to a set of breeding methods usually distinguished  by the objectives (functional or process approach), institutional context (farmer-led  or formal-led),  forms of interaction between farmers and breeders (consultative, collaborative or collegial), location of breeding (centralized or decentralized), stage of...

Methodische Grundlagen der Züchtung von Saflor (Carthamus tinctorius L.) für den ökologischen Landbau
Provedor de dados: 21
Autores: Rudolphi, Sabine.
Saflor (Carthamus tinctorius L.), eine der ältesten Kulturpflanzen der Welt, stammt vermutlich aus dem vorderen Orient. Es handelt sich um eine einjährige, 30-150 cm große Pflanze mit gelben, orangenen oder roten Blüten, die besonders für trockene Standorte gut geeignet ist.  Die Färberdistel, wie Saflor auch genannt wird, wurde ursprünglich zum Färben von Stoffen und Lebensmitteln angebaut. Heute dient sie größtenteils der Ölgewinnung. Das Öl enthält bis zu 89% der ungesättigten Fettsäure Linolsäure und wird meist als Speiseöl verwendet. Der Ölgehalt variiert zwischen 20% und 45%. Die Hauptanbaugebiete sind Indien, Mexiko, USA, Argentinien, Australien und Äthiopien.  Auf nur etwa 2% der ökologisch bewirtschafteten Fläche werden in Deutschland Ölpflanzen...

Stature is affected by many polymorphisms of small effect in humans1. In contrast, variation in dogs, even within breeds, has been suggested to be largely due to variants in a small number of genes2,3. Here we use data from cattle to compare the genetic architecture of stature to those in humans and dogs. We conducted a meta-analysis for stature using 58,265 cattle from 17 populations with 25.4 million imputed whole-genome sequence variants. Results showed that the genetic architecture of stature in cattle is similar to that in humans, as the lead variants in 163 significantly associated genomic regions (P &lt; 5 × 10−8) explained at most 13.8% of the phenotypic variance. Most of these variants were noncoding, including variants that were also expression...

Autores: Nielsen, B.J.
Danish wheat varieties are tested on a set of different Tilletia populations for their level of resistance. Resistance to bunt is studied by inoculating seeds artificially with different populations of bunt before sowing. 5 g of spores per kg of seeds is used, and the ”isolates” used are selected among the 50-60 different populations of bunt collected from different parts of the country. 2-3 different populations are used for inoculation the first year, and varieties showing good resistance are tested further in the following years on 3-6 new populations. The susceptible variety Herzog (up to 86% attack) and the highly resistant variety Stava (normally 0-0.2% attack) are included every year as reference. In July the number of ears with attacks of bunt is...

The objectives of this work were to caracterize the tropical maize germplasm and to compare the combining abilities of maize grain yield under different levels of environmental stress. A diallel was performed among tropical maize cultivars with wide adaptability, whose hybrid combinations were evaluated in two sowing dates, in two years. The significance of the environmental effect emphasized the environmental contrasts. Based on grain yield, the environments were classified as favorable (8,331 kg ha-1), low stress (6,637 kg ha-1), high stress (5,495 kg ha-1), and intense stress (2,443 kg ha-1). None of the genetic effects were significant in favorable and intense stress environments, indicating that there was low germplasm variability under these...

Autores: Koehler-Santos,Patrícia; Dornelles,Ana Lúcia Cunha; Freitas,Loreta Brandão de.
The objective of this work was to characterize mandarin (Citrus spp.) germplasm from Southern Brazil by morphological and molecular analyses. Thirty seven cultivars from 34 distinct mandarin varieties were evaluated by morphological and agronomic traits of leaves, flowers and fruits, and by microsatellite markers. The morphological and agronomic characteristics suggested that almost all varieties can be produced for commercial use, and some, as the Satsuma variety, are recommended for breeding programs. Pooled DNA samples from 1-5 plants belonging to each cultivar were tested. Eight of the nine primers detected polymorphisms. Specific markers were found for some accessions. The dendrogram constructed with the morphological results divided the 37 cultivars...

Extreme homogeneity among Brazilian wheat genotypes determined by RAPD markers
Provedor de dados: 86
Autores: FREITAS,LORETA BRANDÃO DE; JERUSALINSKY,LEANDRO; BONATTO,SANDRO LUIS; SALZANO,FRANCISCO MAURO.
Random amplified polymorphic DNA markers (RAPD) were used to estimate the variability of 14 genotypes of Brazilian wheat (Triticum aestivum L.), using a set of 50 random 10mer primers. A total of 256 reproducibly scorable DNA amplification products were obtained from 48 of the primers, 83% of which were polymorphic. Genetic distances among genotypes were calculated and a dendrogram and a principal coordinates analysis showing the genetic relationships among them were obtained. Despite the low variability found (average genetic distance of 27%), two groups of genotypes could be identified, which probably reflect how they were formed. Studies such as this one may be important in the planning and development of future improvement programs for this plant...

Autores: Mello Filho,Odilon Lemos de; Sediyama,Carlos Sigueyuki; Moreira,Maurílio Alves; Reis,Múcio Silva; Massoni,Guilherme Augusto; Piovesan,Newton Denis.
The objective of this work was to evaluate the effects of selection for high protein on seed physiological quality and grain yield of soybean. Four populations of BC1F4 and four of F4, each from a cross between a commercial variety and a line bearing high protein seeds, were used. The high protein content selection has a tendency to affect negatively the seed physiological quality. Estimates of correlation coefficients between protein content and grain yield were mostly negative but varied among populations. It is possible to obtain lines with high protein content, keeping the grain yield and the seed physiological quality of their respective recurrent progenitors.

The use of wild oat races in artificial hybridization with cultivated oat (Avena sativa L.) has been used as a way of increasing the variability. This work aimed to identify the variability for plant height and flowering date of groups of cultivated oat genotypes, wild introductions of A. fatua L. and segregating populations of natural crosses between A. sativa and A. fatua. Wide genetic variability was observed for both traits in the groups and between them. The wild group of A. fatua L. showed high plants with early maturity, but in the segregating group there was reduced plant height and early maturity. The wild introductions of A. fatua L. studied in this work can be used in oat breeding programs to increase genetic variability by transferring specific...

Autores: Spehar,Carlos Roberto; Santos,Roberto Lorena de Barros.
Twenty six breeding lines, selected from individual plant progenies of hybrids among varieties Amarilla de Marangani, Blanca de Junín, Chewecca, Faro 4, Improved Baer, Kancolla, Real, and Salares-Roja, had their agronomic characters evaluated, in Planaltina, DF, Brazil (15º36'S and 47º12'W), 1,000 masl, in randomized complete blocks, on a Ferralsol, previously limed and fertilized. Grain yield was positively associated with plant height, inflorescence length and diameter, and plant cycle. Genetic gain can be attained by selection based in these characters for commercial production of quinoa in tropical regions.

Autores: Padilha,Alessandro Haiduck; Cobuci,Jaime Araujo; Daltro,Darlene dos Santos; Braccini Neto,José.
Abstract The objective of this work was to verify the gain in reliability of estimated breeding values (EBVs), when random regression models are applied instead of conventional 305-day lactation models, using fat and protein yield records of Brazilian Holstein cattle for future genetic evaluations. Data set contained 262,426 test-day fat and protein yield records, and 30,228 fat and protein lactation records at 305 days from first lactation. Single trait random regression models using Legendre polynomials and single trait lactation models were applied. Heritability for 305-day yield from lactation models was 0.24 (fat) and 0.17 (protein), and from random regression models was 0.20 (fat) and 0.21 (protein). Spearman correlations of EBVs, between lactation...

Autores: Mendes,Beatriz Madalena Januzzi; Boscariol,Raquel Luciana; Mourão Filho,Francisco de Assis Alves; Almeida,Weliton Antonio Bastos de.
The development and optimization of efficient transformation protocols is essential in new citrus breeding programs, not only for rootstock, but also for scion improvement. Transgenic 'Hamlin' sweet orange (Citrus sinensis (L.) Osbeck) plants were obtained by Agrobacterium tumefaciens-mediated transformation of epicotyl segments collected from seedlings germinated in vitro. Factors influencing genetic transformation efficiency were evaluated including seedling incubation conditions, time of inoculation with Agrobacterium and co-culture conditions. Epicotyl segments were adequate explants for transformation, regenerating plants by direct organogenesis. Higher percentage of transformation was obtained with explants collected from seedlings germinated in...

Diallel analysis for grain yield and mineral absorption rate of soybeans grown in acid brazilian savannah soil
Provedor de dados: 86
Autores: Spehar,Carlos Roberto.
High available aluminium and low levels of calcium below the ploughed zone of the soil are limiting factors for agricultural sustainability in the Brazilian Cerrados (Savannahs). The mineral stresses compound with dry spells effect by preventing deep root growth of cultivated plants and causes yield instability. The mode of inheritance for grain yield and mineral absorption ratio of a diallel cross in soybeans [Glycine max (L.) Merrill] grown in high and low Al areas was identified. Differences among the genotypes for grain yield were more evident in the high Al, by grouping tolerant and non-tolerant genotypes for their respective arrays in the hybrids. A large proportion of genetic variance was additive for grain yield and mineral absorption ratio in both...

The pollination ecology and breeding systems of Tabebuia aurea (Manso) Benth. &amp;amp; Hook., and T. ochracea (Cham.) Standl. were investigated in an area of cerrado vegetation in the Federal District of Brazil. These species occur sympatrically, flower massively and synchronously for a month, during the dry season (July to September). Both have diurnal anthesis, with similar floral structures, a yellow tubular corolla and produce nectar. Fourteen species of bees visited both Tabebuia species, but, only three Centris species and Bombus morio, were considered potential pollinators, because of their high frequency on the flowers and their efficiency in carrying pollen. Tests on the breeding systems of T. aurea and T. ochracea demonstrated that boths species...

Autores: Franco,Ana Maria; Goldenberg,Renato; Varassin,Isabela Galarda.
Pollinator guild organization and its consequences for reproduction in three synchronopatric species of Tibouchina (Melastomataceae). In co-flowering plant species, pollinator sharing can result in interspecific pollen transfer and fecundity reduction. Competition will be relaxed whenever there is a large amount of initial pollen supply or if each plant species occupies different habitat patches. Reproduction in Tibouchina cerastifolia (Naudin) Cogn., T. clinopodifolia (DC.) Cogn. and T. gracilis (Bonpl.) Cogn. was studied in an area of Atlantic rainforest to examine whether synchronopatry induces time partitioning among pollinator species. Eleven bee species comprised the pollinator guild. Among pollinators, there were overlaps in bee species composition...

A new device to autonomously feed individualized mantids on extended periods of time
Provedor de dados: 92
Autores: Scherrer,Marcus V.; Aguiar,Alexandre P.
ABSTRACT Mantises can live for many months, are naturally voracious, and feed invariably on live prey. Many species have a propensity for cannibalism and cannot be kept together for most of their life cycle, which makes large-scale rearing typically time-consuming, thus easily becoming prohibitive. This is particularly true for early instars, because they are the most abundant stage of a developmental cohort. Such limitation hinders research on Mantodea which depend on live individuals, such as behavior, physiology, ontogeny, and others. In this work, a simple, low-maintenance “self-service” device is described, which is greatly effective in reducing the time needed for keeping live, individual, small to medium-sized mantises. Trial and error usage and...

Abstract  The lack of programs to improve the strawberry crop in Brazil has led to a growing increase in the use of seedlings imported from Chile, which leads to a certain dependence of imported material on the part of the producers and increases the production even more, since the producers have. This proves even more the need for the development of cultivars adapted to the local conditions of cultivation. In this sense, the aim was to evaluate the post-harvest of fruits of 15 hybrids of strawberry obtained from the cross between commercial cultivars, in order to select the materials with chemical quality superior to the cultivars most planted in Brazil. The contents of soluble solids, titratable acidity, ratio, vitamin C, anthocyanins and phenol were...

ABSTRACT  In recent years, platycarpa peaches have reached high prices due to their good acceptance in the international market. However, the great majority of the released varieties are high chill and do not adapt to Brazilian conditions except on a few microclimes of high altitudes. The cultivar BRS Mandinho is the first peach cultivar of the botanical variety platicarpa, released in Brazil and adapted to subtropical conditions. The plants are vigorous and, in the state of Rio Grande do Sul, the blooming occurs on the second half of July. The fruits are sweet and ripe in November with an average weight of 55.3 g.

Effects of rainfall on bird reproduction in a semi-arid Neotropical region
Provedor de dados: 103
Autores: Cavalcanti,Liana Monique Paiva; Paiva,Luciana Vieira de; França,Leonardo Fernandes.
ABSTRACT In semi-arid ecosystems, birds commonly use rainfall as a reliable environmental cue to adjust the timing and strength of their reproductive activity. Here we evaluate this hypothesis for a community of birds in the Caatinga (the semi-arid region of northeastern Brazil), using brood patch information and nest abundance. Sampling occurred every 14 days between September 2012 and August 2013 (brood patch), and every three or four days during the reproductive period (nests). Abundance of brood patches and nests were correlated, and all brood patches were recorded between March and July (4.5 to 5.0 months).

Provedor de dados: 103
Autores: Costa,Mariellen C.; Medolago,César A.B.; Murcia,Amanda; Francisco,Mercival R.
ABSTRACT The Chestnut-capped Blackbird, Chrysomus ruficapilus (Vieillot, 1819), is a common bird species in flooded areas of South America. Data on its reproductive parameters have been reported mainly for rice paddies from Uruguay and southern Brazil, where reproductive phenology might have been influenced by the chronology of agricultural activities. Here we provide reproductive data for a population in a natural marshland from São Paulo state, southeastern Brazil. A total of 45 active nests were monitored between December 2017 and April 2018. Clutch size was 2.8 ± 0.44. Incubation and nestling periods were respectively 11.8 ± 0.39, and 12.3 ± 0.75 days, and overall nesting success was 65%. The reproductive season lasted about five months, which is...

Provedor de dados: 103
Autores: Branco,Joaquim O.; Costa,Erli S.; Araujo,Jansen de; Durigon,Edison; Alves,Maria Alice S.
We examined the distribution, abundance and density of the Kelp Gull, Larus dominicanus (Lichtenstein, 1823), at Keller Peninsula on two occasions during the breeding season of 2007-2008 (once for incubation and once for chick stages) and compared our results with previously published data. We present information on the number of eggs, incubation success, and initial development of L. dominicanus chicks in the studied sites. The abundance and density of the species has remained statistically similar in Keller Peninsula over the last 30 years (since 1978-1979). Although the abundance and density were almost unchanged, we recorded alterations in the occupation of the breeding areas by L. dominicanus, mainly the abandonment of breeding sites in the eastern...

Reproductive aspects of the Purple-throated Euphonia, Euphonia chlorotica (Aves: Fringillidae) in southeastern Brazil, and first record of the species nesting inside a vespiary
Provedor de dados: 103
Autores: Perrella,Daniel F.; Davanço,Paulo V.; Oliveira,Leonardo S.; Sousa,Livia M.S.; Francisco,Mercival R.
ABSTRACT Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and 2012. Nests were globular with a lateral entrance, and measured 97.9 ± 14.4 mm in outside height, 110.6 ± 11.6 mm in outside diameter, and were 4.88 ± 2.09 m above ground. They were often supported from bellow and were composed mainly of tiny dry leafs and leaflets, fine petioles, and plumed seeds, all compacted with spider web silk. Eggs were laid on consecutive days or with one day interval, and clutch size varied from 1-3 eggs (2.1 ± 0.6, n = 9 nests). Only females incubated the eggs, but both...

Future directions in breeding for disease resistance in aquaculture species
Provedor de dados: 96
Autores: Houston,Ross D.
ABSTRACT Infectious disease is a major constraint for all species produced via aquaculture. The majority of farmed fish and shellfish production is based on stocks with limited or no selective breeding. Since disease resistance is almost universally heritable, there is huge potential to select for improved resistance to key diseases. This short review discusses the current methods of breeding more resistant aquaculture stocks, with success stories and current bottlenecks highlighted. The current implementation of genomic selection in breeding for disease resistance and routes to wider-scale implementation and improvement in aquaculture are discussed. Future directions are highlighted, including the potential of genome editing tools for mapping causative...

Autores: Cardoso,Maximiliano Tadeu Memória; Landim,Aline Vieira; Louvandini,Helder; McManus,Concepta.
Three different genetic groups were evaluated for growth up to slaughter and carcass quality for kill out, commercial cuts, non-carcass components, as well as carcass morphometric measurements. Pure Santa Ines (SI), ½ Ile de France × ½ Santa Ines (I × SI) and ½ Texel × ½ Santa Ines (T × SI) lambs were weighed weekly until they reached predetermined slaughter weight (30, 35, 40 and 45 kg). In both creep feeding and fattening the animals from crosses were superior to the Santa Ines hair sheep in terms of daily weight gain and weaned in less time. Crossbred animals also showed better performance than purebred Santa Ines in terms of commercial cuts and carcass weights. Correlations showed that fat depth and eye muscle area decreased with an increase in...

ABSTRACT The objective of this study was to estimate genetic parameters for body weight of beef cattle in performance tests. Different random regression models with quadratic B-splines and heterogeneous residual variance were fitted to estimate covariance functions for body weights of Nellore and crossbred Charolais × Nellore bulls. The criteria −2 residual log-likelihood (−2RLL), Akaike Information Criterion (AIC), and consistent AIC (CAIC) were used to choose the most appropriate model. For Nellore bulls, residual variance was modeled with six classes of age, and direct additive genetic and permanent environment effects were modeled with quadratic B-splines with two and one intervals, respectively. For crossbred bulls, quadratic B-splines with one...

Genomics to benefit livestock production: improving animal health
Provedor de dados: 96
Autores: Plastow,Graham Stuart.
ABSTRACT The primary principle underlying the application of genomics is that it has the most value for difficult and expensive to measure traits. These traits will differ between species and probably also between markets. Maintenance of health will be one of the biggest challenges for efficient livestock production in the next few decades. This challenge will only increase in the face of demand for animal protein, resistance to existing drugs, and the pressure to reduce the use of antibiotics in agriculture. There is probably genetic variation in susceptibility for all diseases but little has been done to make use of this variation to date. In part this is because it is very difficult as well as expensive to measure this variation. This suggests that...

Autores: Favero,Daniela; Scheffer-Basso,Simone Meredith; Carneiro,Cerci Maria.
The objective of this study was to compare two populations of Crioula alfalfa cultivars, selected by the length of the seedling second internode (Crioula-LI, long internode = 2.5 cm; Crioula-SI, short internode = 1.5 cm) with Alfagraze cultivar in order to verify the seedling morphology value for the selection of more prostrate plants. The plants were grown individually in pots in a semi-protected environment and harvested at 74, 104, 134, 164, 194 and 224 days. Crioula populations varied in terms of height, leaf area, root volume, dry matter yield, and the Crioula-LI population outnumbered that of Crioula-SI. For height, length of internode and primary stem, Alfagraze (45.1 cm, 2.1 cm and 16.7 cm) was similar to Crioula-SI (37.6 cm, 2.3 cm and 18.2 cm);...

ABSTRACT The knowledge of the phenotypic variation of cassava (Manihot esculenta Crantz) germplasm allows the estimative of the genetic variability to support the selection of contrasting genitors. Therefore, the aim of this work was to define homogeneous groups of cassava germplasm based on yield traits, disease resistance and root quality using K-means as a non-hierarchical method. Breeding values estimated by Best Linear Unbiased Predictor (BLUP) were used for the cluster analysis. The number of groups was defined according to the stabilization of the smallest within-group sum of squares. Seventeen clusters were defined to represent the diversity of the germplasm, whose number of accessions ranged from 7 (Group 15) to 69 (Group 9). In general,...

ABSTRACT Fig tree (Ficus carica L.) breeding programs using conventional methods, such as directed crosses, to obtain new cultivars, are unworkable in many countries, including Brazil. Consequently, genetic breeding through mutagenesis has emerged as an important line of research that can improve this crop, and be a significant source of information about this species and assist in the implementation of propagation projects and appropriate management. The aim of this study was to verify the existence of epigenetic variability attributable to DNA methylation in irradiated fig selections when compared both to each other and to the main commercial cultivar, “Roxo-de-Valinhos”, which had previously used methylation-sensitive amplified polymorphism (MSAP) and...

Provedor de dados: 63
Autores: Risso-Pascotto,Claudicéia; Pagliarini,Maria Suely; Valle,Cacilda Borges do.
Some African species of Brachiaria have been introduced into the Americas and became the most important forage for pastures in the tropics. New cultivars can be obtained either from direct selections from the natural existing variability in the germplasm collections or from interspecific hybridizations. Polyploidy is predominant in the genus Brachiaria and correlated with apomixis which complicates hybridization. The objective of cytological studies underway on the Brachiaria germplasm collection at Embrapa Beef Cattle is to determine the chromosome number and meiotic behavior of accessions. For the breeding of Brachiaria species, compatible sexual and apomictic accessions need to be identified. Microsporogenesis was evaluated in two accessions of...

Autores: Santana,Lizziane Gomes Leal; Souza,Edson dos Santos; Passos,Orlando Sampaio; Gesteira,Abelmon da Silva; Ledo,Carlos Alberto da Silva; Soares Filho,Walter dos Santos.
ABSTRACT: Rootstocks influence certain characteristics of the scion, such as vigor, fruit yield and quality, and tolerance to biotic and abiotic factors. In conventional citrus breeding programs, hybridization is the main method used for obtaining rootstock varieties. Between Sept and Oct 2006, controlled pollinations were carried out resulting in nine progenies, totaling 461 hybrid seedlings. The female parents were the ‘Santa Cruz Rangpur’ lime (SCRL) and the ‘Sunki of Florida’ mandarin (SFM), while the male parents, in addition to this mandarin, were the ‘Indio’ and ‘Riverside’ citrandarins, the ‘Thomasville’ citrangequat (THOM), the ‘Swingle’ citrumelo, the ‘Argentina’ citrange (AGC) and the ‘Benecke’ trifoliate orange (BKTO).

Development of maize (Zea mays L.) cultivars with high grain protein and oil concentrations and an appropriate amino acid composition, without losses in grain yield, represents a challenge in breeding programs. The objective of this work was to study the nutritional quality of ten Brazilian maize populations evaluated in three environments. A randomized block design with six replications was used. Ear yield and the concentrations of protein, oil, serine, glutamic acid, alanine, leucine, tyrosine and phenylalanine were evaluated. Individual and combined analyses of variance were performed. Populations diverged for most of the traits. Environmental effects influenced variation for most of the traits, unlike genotype-environment interaction, allowing the...

ABSTRACT: Table grape stands out among the main fruit-bearing plants of irrigated agriculture in the São Francisco Valley region of Brazil. This study estimated repeatability and heritability coefficients and predicted genetic gains in order to select superior genotypes in grape progenies from controlled hybridizations using the Restricted Maximum Likelihood/Best Linear Unbiased Prediction (REML/BLUP) methodology. Individual plants were evaluated for the variables of production (kg per plant), number of bunches, bunch weight (g), berry diameter (mm), and soluble solids content (°Brix). We evaluated 194 hybrids from 30 crosses between Vitis vinifera and interspecific hybrids in Juazeiro, Bahia State, Brazil, over four growing seasons. Repeatability...

Provedor de dados: 63
Autores: Rosso,Beatriz; Pagano,Elba; Rimieri,Pedro; Ríos,Raúl.
Collection of Bromus catharticus Vahl was carried out in the Argentine humid and sub-humid central area. Sixty-eight natural populations are conserved for medium and long term in Pergamino Germplasm Bank and in IRB Germplasm Bank, and ten morphological and agronomic traits were evaluated in the field during two years. There was variability for the traits considered among the accessions. Those populations from the subhumid area showed differences in valuable attributes for breeding. Exploration of marginal areas for this species might be an effective way to add variability to this collection.

Autores: Cesaro,Taniela De; Baggio,Maria Irene; Zanetti,Silvia Andréia; Suzin,Marilei; Augustin,Lizete; Brammer,Sandra Patussi; Iorczeski,Edson Jair; Milach,Sandra Cristina Kothe.
Oat (Avena spp.) is poorly responsive to the haplodiploidization process, which leads to the production of homozygous lines in one step, increasing breeding efficiency. Androgenetic haploids in small grain cereal crops are obtained from microspores cultured at the mononucleate stage, which can be identified by the size of anthers. In order to identify the appropriate anther size for in vitro culture, microspore cytological analyses were made in Avena sativa cultivars UPF 7, UPF 18, UFRGS 14, Stout and Avena sterilis CAV 3361, cultivated in growth chamber under controlled light and temperature conditions. Variation was observed within and among genotypes for anther size at each microspore developmental stage and according to the position of spikelets in the...

Pre-breeding: a link between genetic resources and maize breeding
Provedor de dados: 63
Autores: Nass,Luciano Lourenço; Paterniani,Ernesto.
Activities related to genetic resources are characterized by high cost and long term return. Thus the conservation of genetic variability for the future and the efficient utilization of available accessions are two important goals to be attained. However, the low utilization of germplasm banks is not restricted to Brazil but to other developing countries as well. Therefore, pre-breeding is a promising alternative to link genetic resources and breeding programs. Several aspects for maize are discussed such as concept, importance, methods and results. Problems to be investigated and suggestions are also presented.

Autores: Cortés-Olmos,Carles; Valcárcel,José Vicente; Roselló,Josep; Díez,Maria José; Cebolla-Cornejo,Jaime.
Despite the importance of traditional varieties of tomato (Solanum lycopersicum L.) as sources of variation in breeding programs and varieties targeted to high-price quality markets that value their exceptional organoleptic quality, little is known regarding the structure of these materials at the morphological level. In this study, a collection of 166 populations (137 of them during two years) of traditional varieties of tomato from the east coast of Spain has been characterized using 41 descriptors. The characterization revealed a considerable variation. The segregation observed in several populations (28 %) suggests that apart from the configuration as population varieties, the high variation present in these landraces may be partially due to possible...

ABSTRACT White mold caused by the fungus Sclerotinia sclerotiorum is the most yield-limiting disease of common bean in Brazil. To date, there has been no commercial cultivar resistant to this disease. In a greenhouse we evaluated white mold resistance sources (Cornell 605, A195 and G122) against eight isolates of S. sclerotiorum from five Brazilian states. A Brazilian cultivar (BRSMG Madrepérola) and a susceptible check (Beryl) were used as control. Treatments were arranged in factorial combinations (5 × 8) in a completely random design with four replicates. Disease severity was assessed on a rating scale of 1-to-9 together with lesion length, which was used to determine an area under the disease progress curve (AUDPC). Polymorphisms detected in ten...

Acylsugars present in the accession 'LA716' of Lycopersicon pennellii play an important role in the resistance to Tuta absoluta. This paper investigates the possible association between the resistance to T. absoluta and the acylsugar contents in F2 and F2BC1 tomato plants derived from the interspecific crossing between L. esculentum 'TOM-584' and L. pennellii 'LA716'. From the F2 population, four high acylsugars and one low acylsugars plants were selected and tested for Tuta absoluta resistance along with parental lines TOM-584 and LA-716, and with the checks TOM-600 (high 2-tridecanone line with resistance to T. absoluta) and TOM-556 (low acylsugar line). The genotypes were tested under natural field infestation and were evaluated for overall plant...

Autores: Cobo,Valter José; Fransozo,Adilson.
This study evaluated the influence of the water and air temperatures, pluviosity and photoperiod on the breeding season of Goniopsis cruentata (Latreille, 1803), in Ubatuba littoral, southeastern Brazilian coast. Monthly collections were conducted out from January/95 to December/96 in an estuarine area from 23º29'10"-23º29'45"S to 45º09'10"-45º10'00"W. Water and air temperature variation showed the highest correlation coefficient with the frequency of ovigerous females, r² = 0.73 and 0.68, respectively. However, an analysis of the set of environmental variables, revealed the photoperiod as the factor of highest association with the ovigerous frequency (r² = 0.68). This degree of association allow us to suggest that the breeding season duration of G....

Provedor de dados: 36
Autores: LIMA,Adriana Ferreira.
ABSTRACT Because sex ratio in the broodstock can influence the reproductive behaviour of a species, the influence of sex ratio on the reproductive success of pirarucu, Arapaima gigas, in captivity was assessed. Pirarucu breeders were stocked in 0.10-0.13 ha earthen ponds at three sex ratios in quadruplicate: one male to one female (1M1F); one male to two females (1M2F); and two males to one female (2M1F). Eight spawning events occurred, seven of them with the 1M1F sex ratio, which was the most successful of the three tested sex ratios.

Provedor de dados: 115
Autores: Milosevic,Tomo; Milosevic,Nebojsa.
In situ selection of vineyard peach (Prunus pérsica spp. vulgaris Mill.) genotypes was conducted in 2006 and 2007 in the region of Kfusevac (Central Serbia). Identification, observation and recording of the phenological and pomological properties of the highest-quality genotypes were carried out. Twenty-eight genotypes of the highest quality were selected out of 2093 genotypes, based on biological and pomological properties, and compared to those of cv. Redhaven (control). The onset of flowering varied (April 7-21), being early in two genotypes and late in one genotype, as compared to Redhaven, while 25 genotypes showed an intermediate flowering date, as Redhaven did. Campanula flowers were found in six genotypes, as in Redhaven, and the rosaceous type in...

Autores: GILES,JOÃO ANTONIO D.; OLIOSI,GLEISON; RODRIGUES,WEVERTON P.; BRAUN,HEDER; RIBEIRO-BARROS,ANA I.; PARTELLI,FÁBIO L.
Abstract The morphoagronomic characterization of 12 genotypes of M. esculenta was performed during the 2013/2014 and 2014/2015 crop years. The 12 genotypes were planted in a randomized block design, with four replicates per genotype. Number of tuberous roots per plant, weight of tuberous roots, root yield, total plant weight, harvest index, plant height, height of first branch, number of shoots, stem diameter, number of buds, leaf dry weight and petiole length were evaluated. Genotypes “Camuquem” and “Goiás” were the most productive, and “Amarela” and “Gema de Ovo” were the most divergent. Seventy percent of genetic diversity was due to petiole length (22.86%), root yield (19.20%), weight of tuberous roots (14.89%) and number of buds (13.72%). Overall, the...

Autores: Paschoal,A.F.L.; Santos,J.T.; Mellagi,A.P.G.; Bernardi,M.L.; Wentz,I.; Bortolozzo,F.P.
ABSTRACT This study aimed to evaluate the use of some testicular traits to identify boars with low sperm morphological quality. The consistency (scores from 1 to 5), tone with tonometry (mm), parenchyma echogenicity and heterogeneity with ultrasound (pixel) were assessed in 402 mature boars (18.5 months on average). Sperm abnormality thresholds (≤ 25% of total sperm abnormalities, ≤ 5% of heads, acrosome, neck or midpiece defects, ≤ 10% tail defects, and 15% cytoplasmic droplets) were used to classify boars as approved or disapproved. Three classes of testicular traits were formed (extremely low and high values, approximately 15% each, were kept in separated classes). When the traits were individually evaluated, fewer boars were approved if the...

In order to establish an efficient selection criterion the variability in three asparagus populations was evaluated defining the most important yield components and analysing its evolution along three growing seasons. The yield components, coefficient of variation (CV) and the proportion of plants contributing to 80% of the total yield were estimated. The elite plants were selected by mean of total yield and clusters techniques. Multiple regression showed that spear number (SN) and spear weight (SW) were the most important yield components. In every population, total yield (TY) and SN showed the highest values of CV, independently of sex. 69% of the plants contributed to the 80% of the total yield in the first year while in the second and third year the...

Autores: Petek,Marcos Rafael; Sera,Tumoru; Alteia,Marcos Zorzenon.
The genetic variability for frost resistance was evaluated in field conditions and cold chamber among Coffea accessions. Results showed that C. liberica var. dewevrei and C. racemosa, as well as hybrids obtained from these species were more resistant to frost. There was a great genetic variability for frost resistance among the evaluated sources (b² = 0,98). The correlation estimated between damages in the field and in the cold chamber was 0.933**, therefore, this methodology was efficient and feasible and could be potentially used in a breeding program.

A Bayesian approach was used to predict breeding values and to estimate variance components. Survival was recorded as a binary response: dead plant or live plant during harvest. The total population consisted of 11,520 individual plants. The difference in the magnitude between the best and the worst families was as high as 22%, and varied from 57 to 73%. Survival was found to be highly...

Stability in chromosome number and DNA content in synthetic tetraploids of  Lolium multiflorum after two generations of selection
Provedor de dados: 65
Autores: Pereira,Roselaine Cristina; Santos,Natália de Souza; Bustamante,Fernanda de Oliveira; Mittelmann,Andrea; Techio,Vânia Helena.
ABSTRACT: Chromosome doubling of Italian ryegrass genotypes ( Lolium multiflorum Lam.) adapted to the brazilian edaphoclimatic conditions is an important strategy used by breeders and aims to obtain more vigorous genotypes with better forage quality and disease resistance. The effectiveness of chromosome doubling can be measured by genetic stability and fertility rates of plants over generations. However, a common problem in the polyploidization process is the regeneration of mixoploid plants that have impaired fertility and genetic stability. The objective of this study was to verify if progenies of recently tetraploidized plants remain stable regarding DNA content and chromosome number, over two generations. Progenies of L. multiflorum plants...

This study aimed to characterize the genetic variability in commercial accessions of passion fruit from the Federal District, Brazil, by RAPD markers. Genetic analyses were done with leaf samples of 30 accessions. DNA samples were amplified by RAPD technique, and respective markers converted into a binary matrix, from which the genetic distances between the accessions were estimated. Clustering analyis based on genetic distances allowed to detect a wide range of genetic variabillity among the accessions of sour passion fruit, and to separate them from the two sweet passion fruit. The graphical positioning of 'BRS Ouro Vermelho' confirms its potential to improve the genetic variability of commercial varieties of sour passion fruit. Dispersal of genetic...

Autores: Laviola,Bruno Galvêas; Alves,Alexandre Alonso; Gurgel,Fábio de Lima; Rosado,Tatiana Barbosa; Rocha,Rodrigo Barros; Albrecht,Julio Cesar.
In spite of increasingly widespread interest in planting physic nut, breeding efforts are still in its infancy. In that context, an important resource recently established aiming future breeding efforts was the assembly of a germplasm bank with near 200 accessions. The objective of this study was to estimate genetic parameters, repeatibility coefficients and genetic correlation between seven traits, measured in 110 accessions (half sib families) of this germplasm bank in different stages of development. The results show that higher relative values of additive variance were only found for yield and height, and the existence of low environmental variation (either of temporary or permanent nature) among plots within blocks. Given the high repeatibility values...

Autores: Bispo,Noryam Bervian; Tessele,Carolina; Barbosa Neto,José Fernandes.
Genetic variability is the basis of plant breeding. In corn, a large and diverse genetic pool permits manipulation of different genotypes, but the genetic diversity of tropical germplasm has been little studied. With the objective of analyzing the amplitude of the genetic variability in 15 hybrids released in different periods by three different seed companies, phenotypic and molecular characterization was carried out in three environments and at two plant densities. The phenotypic assessment showed great similarity among the hybrids, suggesting that the breeding programs have developed genotypes with similar phenotypic traits. The dendogram of the molecular analysis showed clustering according with the different companies suggesting that each corn...

Autores: Castro,Jaqueline de Oliveira; Veloso,Alessandro Vieira; Yanagi Junior,Tadayuki; Fassani,Edison José; Schiassi,Leonardo; Campos,Alessandro Torres.
Quail breeding is a viable alternative for animal production and due to its low investment, fast return of invested capital, use of small areas and creation of jobs has aroused much interest in Brazil. The aim of this study was to develop a model based on fuzzy set theory to predict the weight of eggs from Japanese quails. The proposed fuzzy model was based on data from field measurement experiments, as well as from literature referring to the influence of environment over the weight of eggs. To develop the fuzzy system, air dry-bulb temperature (t db, ° C) and relative air humidity (RH, %) were defined as input variables and trapezoidal and triangular membership functions were used, respectively. The absolute deviation between the values for observed egg...

Resistance of potato clones to necrotic recombinant strains of potato virus y (pvy)
Provedor de dados: 64
Autores: Ribeiro,Silvia Regina Rodrigues de Paula; Pinto,César Augusto Brasil Pereira; Costa,Suellen Bárbara Ferreira Galvino; Menezes,Mariney de; Figueira,Antonia dos Reis.
The Ry adg allele is widely used by breeders to confer extreme resistance to all strains of PVY. However, the necrotic strain has increased recombination resulting in recent considerable losses in productivity. Thus far, not all necrotic recombinant strains of PVY have been tested for their reaction to the Ry gene. The objective of this study was to identify potato clones carrying the resistant allele and to assess their reaction to the following recombinant strains: NTN (PVY NTN), Wilga (PVY N-Wi), and "curly top" (PVY E). Advanced clones from the potato breeding program at Universidade Federal de Lavras were evaluated through a specific molecular marker for the Ry adg allele. The clones carrying the resistance allele were grafted on tobacco plants...

Autores: Melo,Dheyne Silva; Pinto,César Augusto Brasil Pereira; Peixouto,Leandro Santos; Neder,Diogo Gonçalves; Assis,Josiane Cristina de.
Clonal selection is the preferred breeding method used in potatoes (Solanum tuberosum L.). However this selection procedure is only efficient for more advanced generations and shows no good results when applied in the seedling up to the second clonal generation. This study assessed the feasibility of selection in early generations of full-sib potato families and compares the selection method among and within families with the combined selection under different selection intensities. Six experiments were conducted from the first (C1) until the third clonal generation (C3). In C1 a randomized complete block design with four replications of 25 plants was used. In the remaining generations RCB was employed with three replications of 10 plants. Genetic...

Autores: Ematné,Hugo Junqueira; Nunes,José Airton Rodrigues; Souza,João Cândido de; Muñoz,Patrício Ricardo.
ABSTRACT Recurrent selection is a viable alternative for popcorn breeding. However, frequent verification of progress attained is required. The aim of this study was to estimate the genetic progress attained for popping expansion (PE) and grain yield (GY) after four cycles of recurrent selection and to compare this progress with the expected progress estimated at the end of each cycle while considering the genetic relationships between the progenies via univariate and multivariate mixed-model approaches. To estimate the genetic parameters and gains from indirect selection, cycles 1, 2, 3, and 4 of a UFLA population were used. To estimate the genetic gains achieved, the following cycles were used: UFLA (original) and cycles 0, 1, 2, 3, and 4, evaluated in...

Provedor de dados: 64
Autores: Oliveira,Celso Mattes de; Andrade Júnior,Valter Carvalho de; Maluf,Wilson Roberto; Neiva,Irã Pinheiro; Maciel,Gabriel Mascarenhas.
We examined the resistance of improved tomato strains rich in 2-tridecanone (2-TD), zingiberene (ZGB) and acyl sugars (AA) to the tomato moth, Tuta absoluta. We also studied whether selection for strains with higher densities of glandular trichomes, and thus presumably strains with higher concentrations of 2-tridecanone, was effective in promoting greater resistance to the moth. The TOM-584 and TOM-679 strains were used as susceptible controls, which have normal concentrations of the three allelochemicals. The improved strain TOM-687, which has a high AA content, has a widely documented resistance and was used as a standard resistant strain. The wild strain PI134417, which is resistant by means of its high 2-TD content, was also used as a standard...

Tolerância à dessecação de sementes de espécies silvestres de maracujazeiro.
Provedor de dados: 14
Autores: AUD, F. F.; JUNGHANS, T. G.
O primeiro desafio para a conservação de lotes de sementes é a determinação de sua tolerância à dessecação. A partir desse conhecimento, é possível estabelecer as condições mais adequadas para o seu armazenamento, visando à conservação por períodos prolongados. Em ambientes em que a ocorrência de pragas e doenças pode contaminar grandes lotes de sementes ou em que há um grande volume de trabalho em laboratórios, a tomada de decisão sobre o armazenamento de materiais desconhecidos quanto à tolerância, a dessecação deve ser feita de maneira rápida e eficiente. Estabelecer protocolos de armazenamento e germinação para uma grande diversidade de genótipos pode ser uma tarefa muito demorada por causa das peculiaridades das sementes de cada espécie. Assim,...

Autores: CARGNIN, A.
ABSTRACT: The recurrent selection is a dynamic and continuous process, which involves the obtainment of individuals or families, evaluation, selection and intercrossing of the best ones, aiming to increase the frequence oft he favourable alleles and, consequently, improve the expression of the character selction. The recurrent selection may be carried out in two manners concerning the selection method: selection in individual level also denoted as phenotypic selection or massal selection; and selection in family level, in which populations structured in families are used. The estimatives of the genetic improvements attained by breeding with recurrent selection are a useful tool to quantify the efficiency of the executed works. Differences among the...

Carry-over body mass effect from winter to breeding in a resident seabird, the little penguin
Provedor de dados: 5
Autores: Salton, Marcus; Saraux, Claire; Dann, Peter; Chiaradia, André.
Using body mass and breeding data of individual penguins collected continuously over 7 years (2002–2008), we examined carry-over effects of winter body mass on timing of laying and breeding success in a resident seabird, the little penguin (Eudyptula minor). The austral winter month of July consistently had the lowest rate of colony attendance, which confirmed our expectation that penguins work hard to find resources at this time between breeding seasons. Contrary to our expectation, body mass in winter (July) was equal or higher than in the period before (‘moult-recovery’) and after (‘pre-breeding’) in 5 of 7 years for males and in all 7 years for females. We provided evidence of a carry-over effect of body mass from winter to breeding; females and males...

Reciprocal Recurrent Selection between Synthetic Multi Species Populations (RRSSMSP) of Eucalypt
Provedor de dados: 190
Autores: Resende, Marcos Deon Vilela de; Assis, Teotônio Francisco de.
It is proposed a breeding strategy for eucalypt, which congregates in an individual desirable traits belonging to different species and capture the heterosis for growth, stemming from several pair of species of known heterotic behavior. Such strategy relies on obtaining two synthetic multi species populations and posterior reciprocal recurrent selection (RRS) between them. It is called reciprocal recurrent selection between synthetic multi species populations (RRS-SMSP) and improves the traits drought, disease resistance, volume, density, yield and lignin content. Options for making the synthetic multi species populations are presented. The RRSSMSP is suitable for applying the genomic selection.

Autores: Tulmann Neto,Augusto; Alves,Marcelo Correa; Camargo,Carlos Eduardo de Oliveira; Castro,Jairo Lopes de; Ferreira Filho,Wilson Penteado.
Seed from the sensitive wheat (Triticum aestivumL.) cultivar Anahuac was treated to gamma-ray irradiation and eleven Al3+ tolerant mutants selected. The objective was to compare these mutants to the original Anahuac and to the tolerant wheat cultivars IAC-24 and IAC-60 from 1994 to 1996 in acid (Capão Bonito) and limed (Monte Alegre do Sul) soil field trials, in the State of São Paulo, Brazil. Grain yield and agronomic characteristics were analyzed. All the mutant lines yielded higher than the sensitive Anahuac cultivar in the acid soils of Capão Bonito. Under limed soil conditions, 10 mutants had a similar yield to the original sensitive cultivar and one a lower yield. The majority of the mutants were similar in yield to the tolerant cultivars IAC-24 and...

Autores: Studer,Anita; Sousa,Marcelo Cardoso de; Barcena-Goyena,Begoña.
ABSTRACT We present the results of a 26-year study on the breeding biology of the Short-tailed Antthrush, Chamaeza campanisona (Lichtenstein, 1823) in an Atlantic rainforest remnant of northeastern Brazil (Alagoas/Pernambuco). We followed the fate of 38 nests, of which 19 failed, 11 succeeded and 8 had an unknown fate. The presence of most nests coincided with the beginning of the rainy season in March/April but nests with eggs and/or chicks were found throughout the year, with no records only in January. Nests were placed inside natural tree cavities that result from broken branches and trunks. Both parents were engaged in feeding the chicks, their diet consisted mainly of insects, spiders, and some unidentified berries. All nests had a clutch size of two...

Autores: Akbarpour, Omid Ali; Dehghani, Hamid; Sorkhi-Lalelo, Bezad; Kang, Manjit Singh.
Genotype-by-environment interaction refers to the differential response of different genotypes across different environments. This is a general phenomenon in all living organisms and always has been one of the main challenges for biologists and plant breeders. The nonparametric methods based on the rank of original data have been suggested as the alternative methods after parametric methods to analyze data without perquisite assumptions needed for common analysis of variance. But, the lack of statistical software or package, especially for analysis of two-way data, is one of the main reasons that plant breeders have not greatly used the nonparametric methods. Here, we have explained the nonparametric methods and presented a comprehensive two-parts SAS...

Ceftiofur-loaded PHBV microparticles: A potential formulation for a long-acting antibiotic to treat animal infections
Provedor de dados: 69
Autores: Vilos,Cristian; Constandil,Luis; Herrera,Natalia; Solar,Paula; Escobar-Fica,Jorge; Velásquez,Luis Alberto.
Background: The infectious diseases in the livestock breeding industry represent a significant drawback that generates substantial economic loss and have led to the indiscriminate use of antibiotics. The formulation of polymeric microparticles loaded with antibiotics for veterinary use can: reduce the number of required doses; protect the drug from inactivation; and maintain a sustained-release of the antibiotic drug at effective levels. Accomplishing all of these goals would have a significant economic and animal health impact on the livestock breeding industry. Results: In this work, we formulated ceftiofur-loaded PHBV microparticles (PHBV-CEF) with a spherical shape, a smooth surface and diameter sizes between 1.65 and 2.37 &amp;#956;m. The...

ESTIMATION OF RESPIRATORY FREQUENCY AND RECTAL TEMPERATURE ON PIGS IN HEAT STRESS BY FUZZY LOGIC
Provedor de dados: 70
Autores: Oliveira,Rodrigo F. de; Ferreira,Rony A.; Abreu,Lucas H. P.; Yanagi Júnior,Tadayuki; Lourençoni,Dian.
ABSTRACT Physiological parameters such as respiratory frequency and rectal temperature stand out as indicators for heat stress in pigs, however, requiring time and labor for measurements. The possibility of using infrared thermography associated with prediction systems of these physiological variables can help in decision making, allowing greater welfare and productivity of the animals. With this objective, an experiment was carried out with growing pigs submitted to acute and chronic heat stress, working with a thermoneutrality temperature (22° C) and heat stress (34° C). The results were used for the development of a fuzzy model using as input variables: air dry bulb temperature (°C), average surface temperature (°C) and, as output variables: respiratory...

Provedor de dados: 73
Autores: GÓMEZ P,PERSY; LILLO,DIANA; GONZÁLEZ,ALEJANDRA V.
Adesmia bijuga Phil. is an endemic shrub in central Chile, classified as a critically endangered species of plant. After more than 100 years since its original description by R. A. Philippi (1884), the species was rediscovered exclusively in two locations of the Maule Region. One of them, Fundo San Pedro-Las Cañas, is close to extinction with a low number of shrubs, occurring in a disturbed habitat due to plantations of Pinus radiata. This study examined the pollination biology and breeding system of A. bijuga in order to explain their small number of shrubs. We estimated composition of pollinator species attracted to flowers and visitation rates. In order to describe its breeding system in A. bijuga we used manipulated treatments to estimate autonomous...

Autores: Silveira,Sheila Recepute; Ruas,Paulo Maurício; Ruas,Claudete de Fátima; Sera,Tumoru; Carvalho,Valdemar de Paula; Coelho,Alexandre Siqueira Guedes.
The RAPD technique associated with restriction digestion of genomic DNA was used to assess the genetic variability within and among nine populations of Coffea arabica, including six progenies belonging to the Sarchimor germplasm, the progeny PR 77054-40-10 (Catuaí Vermelho IAC 81 x Icatu), and two commercial cultivars (IAPAR 59 and Catuaí Vermelho IAC-81). These populations were evaluated using analysis of molecular variance (AMOVA), genetic similarity among progenies, and percentage of polymorphic loci. A total of 99 RAPD markers were evaluated of which 67 (67.67%) were polymorphic. AMOVA showed that 38.5% and 61.5% of the genetic variation was distributed among and within populations, respectively. The fixation index (F ST) of the genotypes was 0.385....

We report a sampling strategy based on Mendelian Breeding Units (MBUs), representing an interbreeding group of individuals sharing a common gene pool. The identification of MBUs is crucial for case-control experimental design in association studies. The aim of this work was to evaluate the possible existence of bias in terms of genetic variability and haplogroup frequencies in the MBU sample, due to severe sample selection. In order to reach this goal, the MBU sampling strategy was compared to a standard selection of individuals according to their surname and place of birth. We analysed mitochondrial DNA variation (first hypervariable segment and coding region) in unrelated healthy subjects from two different areas of Sardinia: the area around the town of...

A segregant bulk population derived from a single cross between the Carioca MG cultivar and the ESAL 686 line was used to investigate whether the action of natural selection in the direction required by the breeders and the delaying line extraction would increase the chance of obtaining families with greater grain yield. The populations were advanced from F2 to F24 and obtained families F2, F8 and F24 from the plants. These families and their parents were assessed for grain yield (kg/ha) in Lavras-MG in three sowing seasons (July 2001, November 2001 and March 2002) in an 18 x 18 lattice design with two replications in the first sowing and three in the other two.

Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybridization), and the meiotic index and pollen viability of F1 hybrids. In F1 cells from both hybrids, 11 chromosomes of each parental was observed, as expected, but chromosome rearrangement events could be detected using rDNA chromosome markers, suggesting unbalanced cells. In the BC1F1, both hybrids had 22 chromosomes, suggesting that only n = 11 gametes were viable in the next generation. However, GISH...

Autores: Viana,José Marcelo Soriano; Matta,Frederico de Pina.
Estimation of general and specific combining ability effects in a diallel analysis of cross-pollinating populations, including the selfed parents, is presented in this work. The restrictions considered satisfy the parametric values of the GCA and SCA effects. The method is extended to self-pollinating populations (suitable for other species, without the selfed parents). The analysis of changes in population means due to inbreeding (sensitivity to inbreeding) also permits to assess the predominant direction of dominance deviations and the relative genetic variability in each parent population. The methodology was used to select popcorn populations for intra- and inter-population breeding programs and for hybrid production, developed at the Federal...

Caffeine inheritance was investigated in F2 and BC1F1 generations between Coffea arabica var. Bourbon Vermelho (BV) and Coffea canephora var. Robusta 4x (R4x). The caffeine content of seeds and leaves was determined during 2004 and 2005. Microsatellite loci-markers were used to deduce the meiotic pattern of chromosome pairing of tetraploid interspecific hybrids. Genetic analysis indicated that caffeine content in seeds was quantitatively inherited and controlled by genes with additive effects. The estimates of broad-sense heritability of caffeine content in seeds were high for both generations. In coffee leaves, the caffeine content (BSH) from the same populations showed transgressive segregants with enhanced levels and high BSH. Segregation of...

Abstract The illegal trade is a major threat to many bird species, and parrots are common victims of this activity. Domestic and international pet markets are interested on different parrot species, such as the Blue-and-yellow Macaw (Ara ararauna). This South American macaw is not globally threatened, but is under protection from over-exploitation. This study aimed to identify and characterize novel microsatellite loci for population and parentage analysis of A. ararauna. Scaffold sequences of Ara macao available in the NCBI database were used for microsatellite searches using MsatCommander software. We tested a total of 28 loci, from which 25 were polymorphic, one was monomorphic, and two did not generated amplification products. For polymorphic loci, the...

Genetic evaluation of the mating system in the blue-and-yellow macaw (Ara ararauna, Aves, Psittacidae) by DNA fingerprinting
Provedor de dados: 74
Autores: Caparroz,Renato; Miyaki,Cristina Y.; Baker,Allan J.
More than 90% of birds are socially monogamous, although genetic studies indicate that many are often not sexually monogamous. In the present study, DNA fingerprinting was used to estimate the genetic relationships between nestlings belonging to the same broods to evaluate the mating system in the socially monogamous macaw, Ara ararauna. We found that in 10 of 11 broods investigated, the nestlings showed genetic similarity levels congruent with values expected among full-sibs, suggesting that they shared the same parents. However, in one brood, the low genetic similarity observed between nestlings could be a result of intraspecific brood parasitism, intraspecific nest competition or extra-pair paternity. These results, along with available behavioral and...

Brazilian goats are generally kept in small herds and extensive rearing systems, mainly in the northeastern region of the country. Despite production improvement in recent years, the lack of pedigree control has affected genetic progress. This study aimed to validate a panel of 16 microsatellites for parentage testing in locally adapted and commercial goats breeds raised in Brazil, as well as to compare its efficiency with the panel recommended by the Brazilian Ministry of Agriculture, Livestock and Supplies (MAPA) in 2004. The number of alleles and expected heterozygosity (He) per marker ranged from four to 18, and from 0.051 to 0.831, respectively. Using all markers, 100% of parentage cases of the validation dataset were resolved with a strict confidence...

Autores: Marques,Maria José; Vizú,Juliana de Fátima; da Silva Filho,Danilo F; Ticona-Benavente,César Augusto.
ABSTRACT This study aimed to select endogamic progenies of tomato cv. Yoshimatsu and to conduct a progeny test in the state of Rondônia. The experiment was carried out in a randomized block design with four replicates and eight plants per plot, spacing 1x0.5 m, with one stem. A significant variation was observed among the fifteen progenies for productivity (2.0-5.5 kg plant-1), seed mass with placenta (18-31.5 g fruit-1), number of fruits per plant (18.8-38.7) and soluble solids (3.4-4.2°Brix). No significant variation was noticed for fruit size, pericarp thickness, number of locules, pH, number of flowers and fruit set, though. P6 progeny showed to be the most productive one (110 t ha-1): average fruit mass was 142.5 g, salad type tomato, 7.5 locules,...

Heterosis and combining ability of dual-purpose tomato hybrids developed to meet family farmers' needs in Brazil and Mozambique
Provedor de dados: 75
Autores: Graça,António JP; Amaral Júnior,Antonio T; Rodrigues,Rosana; Gonçalves,Leandro SA; Sudré,Cláudia P; Vivas,Marcelo; Melo,Paulo CT.
Brazil is the world eighth largest tomato producer and, within the country, the tomato production chain is segmented according to fruit destination: fresh consumption and processing (industrial supply). In contrast, Mozambique does not have a differentiated chain and cultivars are expected to serve both purposes. As there are no tomato breeding programs in Mozambique, cultivars used in the country come from other regions of the world, including Brazil. This paper describes the development and assessment of tomato hybrids with dual-purpose: fresh use and processing. Five tomato genotypes (B13LD, Castone, Massag-72, "Viradoro", and "Rio Grande") were crossed in complete diallel design without reciprocal, and the general and specific combining ability (GCA...

Autores: Gomes,Gisely Paula; Constantino,Leonel Vinicius; Corte,Ligia Erpen-Dalla; Riger,Cristiano Jorge; Chaves,Douglas S de A; Gonçalves,Leandro SA.
ABSTRACT Capsicum baccatum is one of the main chili pepper species grown and consumed in South America. In Brazil, C. baccatum var. pendulum is widely cultivated, especially “dedo-de-moça” type. For most horticultural crops, including Capsicum species their diversity remains under-explored for traits related to fruit quality, since over the past half century breeding efforts have focused mainly on good agronomic performances. The investment in screening traits such as flavor, nutritional compounds and antioxidant content in traditional varieties is very important to support fruit quality breeding efforts. Thus, the objective of this study was accessing the variations into content of soluble solid, acidity, capsaicinoid, vitamin C, total phenolic compounds...

ABSTRACT The Registro Nacional de Cultivares [RNC (National Register of Cultivars)] and the Serviço Nacional de Proteção de Cultivares [SNPC (National Service for Cultivar Protection)] were established by the Ministry of Agriculture, Livestock and Food Supply (MAPA) in 1997. The registration of a cultivar in the RNC allows the production, processing and commercialization of seeds in the country. The right of commercial exploitation, assured by the protection of a cultivar in the SNPC, allows the allocation of resources to public and private breeding programs, and the subsequent launching of new cultivars. The authors’ experience with the theme and its relevance to the public and private sectors provided the base for this article, thus sharing the elements...

ABSTRACT The success of breeding programs depends on genetic variability. Individuals selected based on a few traits may be a limitation. One alternative is the use of nonparametric indices. However, there is no information on the use of selection indices in melon germplasms. The present study aimed to estimate genetic dissimilarity in a melon germplasm and select potential parent plants for future breeding programs. The genetic material consisted of 37 melon accessions. The traits assessed were fruit diameter and length, diameter and length of the fruit cavity and total soluble solids. Genetic dissimilarity was assessed by multivariate analyses (UPGMA and Tocher). Selection gain estimates were analyzed by comparing the classic Smith-Hazel and sum of ranks...

Strawberry breeding in Brazil: current momentum and perspectives
Provedor de dados: 75
Autores: Zeist,André Ricardo; Resende,Juliano Tadeu V de.
ABSTRACT Brazil depends almost entirely on imported strawberry cultivars, which burdens production costs and results in the use of genotypes with less adaptation to the Brazilian cropping conditions. To reverse this scenario, it is necessary to strengthen strawberry breeding in Brazil. Otherwise, the country will remain dependent on imported cultivars and producers will continue to be required to collect royalties. In this context, public institutions in Brazil, such as the State University of the Midwest Paraná (UNICENTRO), have been successfully conducting strawberry breeding programs, with the objective of launching cultivars in the short term. Crosses between the cultivars in use in the country, with the subsequent development and selection of...

Genetic improvement of horticultural crops mediated by CRISPR/Cas: a new horizon of possibilities
Provedor de dados: 75
Autores: Koltun,Alessandra; Erpen-Dalla Corte,Lígia; Mertz-Henning,Liliane Marcia; Gonçalves,Leandro SA.
ABSTRACT The burden of the current global challenge involving food security lies in the need to improve crop production. In this regard, biotechnology stands out as an essential tool to generate plants able to cope with pests, diseases, and harsh climatic conditions, and more efficient in the use of natural resources. An advanced approach to create genetic variability in a precise and targeted way, the genome-editing technique CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR associated proteins), has drawn the attention of breeders. The genome editing CRISPR/Cas system relies on a guiding RNA that directs a nuclease to generate a double-strand break (DSB) at a target DNA, activating the cell repair systems and eventually leading...

New sources of partial resistance to bacterial spot race T2 in processing tomatoes
Provedor de dados: 75
Autores: Berrueta,María C; Giménez,Gustavo; Galván,Guillermo A; Borges,Alejandra.
ABSTRACT Bacterial leaf spot of tomato is caused by four Xanthomonas species, among which Xanthomonas vesicatoria race T2 predominates in Uruguay. Difficulties in integrated disease management and the rapid spread of the pathogen led to investigations of genetic resistance. This study aimed to identify resistance sources to bacterial leaf spot race T2 in tomato for processing. Twelve genotypes were evaluated under field conditions in 2010 and 2011. Plants were spray-inoculated with a suspension of bacteria (108 cfu/mL) 15 days after transplantation. Incubation period, disease severity on leaves, and the percentage of fruits with symptoms at harvest were determined. The incubation period did not differ among the genotypes. The genotype 'Hawaii 7981' had the...

Combining ability in sweet pepper for resistance to powdery mildew
Provedor de dados: 75
Autores: Marchesan,Cristina B; Melo,Arlete MT de; Paterniani,Maria Elisa AGZ.
With the increase of the production of pepper in protected environment, pathogens began to cause serious damages to producers such as Leveillula taurica (Lév.) Arn., fungus that causes powdery mildew. The systemic fungicides have not shown very satisfactory results. Thus, considering that protected cropping of pepper in Brazil is significant and growing, the incorporation of genes that confer resistance to powdery mildew is important for the maintenance of this cropping system. In this research, carried out in 2007 in Campinas, São Paulo State, Brazil, the agronomic performance and resistance to powdery mildew was determined by triple hybrids of sweet pepper through general and specific combining ability of their parents. For agronomic performance of the...

ABSTRACT Belonging to the Oomycete class, Phytophthora capsici has wide range of host profile and is responsible for many devastating diseases in many countries. In addition to time consuming problem for transferring resistance to susceptible varieties, backcrossing method causes losing of genes providing resistance to susceptible varieties. In this study transferring P. capsici resistance genes to susceptible chili pepper lines was aimed during the extensive breeding period and resistant lines were confirmed by marker assistance. Two different breeding populations from CM334 and PM217 were compared by stem inoculation test to determine receptivity, inducibility, and stability resistance component. CM334 was found more effective for transferring all...

Seasonality, age structure and reproduction of Leptodactylus (Lithodytes) lineatus (Anura, Leptodactylidae) in Rondônia state, southwestern Amazon, Brazil
Provedor de dados: 76
Autores: Bernarde,Paulo Sérgio; Kokubum,Marcelo N. de C.
Leptodactylus(Lithodytes) lineatus (Schneider, 1799) is an Amazonian leaf litter frog considered rare or uncommon in several studies on anuran communities. Despite being a widely distributed frog in Amazonian forests, knowledge of the biology and ecology of this species is relatively scarce. This species has been reported to live in association with leaf-cutter ant nests (Atta spp.) during the breeding period. In this paper we present data on the seasonality of this species and some reproductive information gathered at a locality of Rondônia state, northwestern Brazil. Field work was carried out between April 2001 and March 2002, with the use of pitfall traps with drift fences as a survey method. Leptodactylus (L.) lineatus had a higher capture frequency...

Melhoramento genetico de mandioca.
Provedor de dados: 14
Autores: FUKUDA, W. M. G.
Variedade de mandioca e um dos principais componentes para o desenvolvimento do sistema produtivo dessa cultura, alem de constituir uma tecnologia que nao implica em custos adicionais para o produtor. Apesar da mandioca apresentar um alto potencial produtivo, estimado por COCK (1974) em 90 t/ha/ano, a produtividade nacional esta em torno de 12 t/ha. Um dos fatores que tem contribuido para a baixa produtividade desse cultivo no Brasil, e o uso de variedades com baixo potencial produtivo. A demanda por novas variedades de mandioca vem crescendo constantemente, a medida que surgem novas alternativas de uso pelo produto, bem como a expansao de novas fronteiras agricolas para o plantio dessa cultura. Para atender essas demandas, e importante definir-se as...

? O objetivo deste trabalho foi avaliar a resistência de populações de mamoeiro transgênicas (PTP) ao vírus da mancha anelar do mamoeiro (Papaya ringspot virus, PRSV-P). Plantas transgênicas da variedade Sunrise Solo foram produzidas com versões traduzíveis e não traduzíveis do gene da proteína PRSV-P e foram inoculadas mecanicamente com o PRSV em casa de vegetação para fazer uma observação preliminar de sua reação ao vírus. A presença do gene CP/PRSV e sua homozigose foi avaliada por reação em cadeia da polimerase e as plantas selecionadas em função desta característica, bem como o controle Sunrise Solo foram transplantados para o campo para avaliações agronômicas. Na avaliação em casa de vegetação, entre 5,8% e 96,3% de plantas das PTP apresentaram...

Avaliação de híbridos intervarietais e variedades de milho em várzea do Amazonas.
Provedor de dados: 14
Autores: BARRETO, J. F.; SÁ SOBRINHO, A. F. de; SÁ, A. C. R. de.
Visando obter um estágio intermediário de tecnologia, instalou-se um ensaio dialélico de 18 populações parentais e dois híbridos duplos. De uma maneira geral, os cruzamentos apresentaram porte baixo, ciclo precoce, boa resistência a doenças e acamamento. Os rendimentos das melhores populações parentais sugerem trabalhos de melhoramento visando obterem-se híbridos intervarietais mais produtivos.

Diversidade genética e desempenho agronômico de híbridos de cajueiro: recursos para o melhoramento genético.
Provedor de dados: 14
Autores: HAWERROTH, M. C.; BORDALLO, P. do N.; VIDAL NETO, F. das C.; MELO, D. S.
A implantação de cajueirais com clones anões-precoces geneticamente superiores representa uma possibilidade de mudança efetiva no cenário produtivo nacional, uma vez que facilita o manejo adequado da planta, uma maior uniformidade na qualidade de castanhas e pseudofrutos e o aumento expressivo na produtividade, que, em regime de sequeiro, pode ser superior a 1.000 kg ha-1 de castanhas (Martins Junior et al., 2008; Vidal Neto et al., 2013), elevando assim a rentabilidade da atividade. Entretanto, a busca por clones superiores, em produtividade e características exigidas pelo mercado, pode ocasionar, muitas vezes, a redução da base genética e a consequente redução da capacidade de resposta aos efeitos adversos do ambiente. Conjuntamente, a caracterização...

Estimativas de volume de pinus caribaea var. hondurensis no Cerrado do Distrito Federal, DF.
Provedor de dados: 14
Autores: MORAES NETO, S. P. de.
O presente trabalho teve como objetivo testar vários modelos matemáticos que expressam a relação entre o volume com diâmetro à altura do peito de troncos de Pinus caribaea var. hondurensis e a altura comercial, e selecionar o modelo de melhor ajuste e precisão. Foram ajustados nove modelos tradicionais utilizados no setor florestal. A seleção do melhor modelo foi baseada nos seguintes critérios: coeficiente de determinação ajustado, erro padrão da estimativa e análise gráfica de resíduos. Concluiu-se que o melhor modelo para expressar o volume individual de árvores, com e sem casca, foi o de Meyer, no Cerrado do DF.

Genetic basis of summer mortality in juvenile cupped oysters
Provedor de dados: 5
Autores: Degremont, Lionel; Boudry, Pierre; Bedier, Edouard; Ropert, Michel; Soletchnik, Patrick; Huvet, Arnaud; Moal, Jeanne; Samain, Jean-francois.
The French project "Morest", coordinated by IFREMER, aims to understand the causes of the summer mortalities in Crassostrea gigas. In 2001, three sets of families were bred following a nested half-sib mating design. 17 half-sib families (HSF) were obtained in this first generation (G1) and reared in 3 sites. Significant differences in survival were observed among HSF, and some HSF showed high levels of mortality in all sites, clearly indicating a genetic basis for survival. In 2002, a second generation (G2), including divergent selection and inbred lines, was constituted. Monitoring of survival and growth of G2s were the same as in 2001. Significant differences in survival were found between the offspring of the "high" and "low" selected groups and between...

Can individual feed conversion ratio at commercial size be predicted from juvenile performance in individually reared Nile tilapia Oreochromis niloticus?
Provedor de dados: 5
Autores: Rodde, Charles; Chatain, Beatrice; Vandeputte, Marc; Quoc Trinh, Trong; Benzie, John A.h.; De Verdal, Hugues.
Feed conversion ratio (FCR), the ratio between feed intake and body weight gain, is of major interest for improving aquaculture sustainability through reduced feed costs and environmental impacts. Demonstrating whether FCR measured in juvenile fish is an accurate predictor of their performance during the whole rearing period is critical to developing genetic improvement programs for this trait. This is especially true for estimates obtained in individually reared fish, for which this has high implications regarding the size of the necessary rearing structures. We obtained individual FCR from 30 male Nile tilapia Oreochromis niloticus from the GIFT strain individually reared in a recirculating system, from 36 to 260 g mean weight. They were fed twice a day...

Overwiew on selective breeding and genetic improvement in bivalve shellfish
Provedor de dados: 5
Autores: Boudry, Pierre.
Dr. Boudry focussed his talk on oysters, which are the most important bivalve species produced world wide (more than 4 million tons). One of the main characteristic of bivalve aquaculture is that most of the juveniles ("seed or "spat") are collected from natural recruitment (e.g. 100% of the European mussel production). Hatchery propagation is used in the case of introduced species (e.g. Crassostrea gigas in USA)  or limited natural recruitment.    The most significant genetic improvement for the production of Pacific oyster (C. gigas) to date has been obtained through the breeding of triploids, especially since the development of tetraploids. Triploidy lead to highly reduced gametogenesis and, as a result better growth and survival.  Many quantitative...

Plan de relance de l'huître plate Ostrea edulis L.. Travaux 1985.
Provedor de dados: 5
Autores: IFREMER.
La situation épidémiologique due à Bonamia ostreae n'a pas évoluée au cours de 1985. Les élevages réalisés dans le cadre du plan de relance ont confirmé la très faible propagation du parasite,en eau profonde, jusqu'à l'âge de deux ans. Des résultats encourageants ont également été obtenus avec des huîtres plus âgées. Les essais d'acclimatation effectués avec Ostrea angasi ont permis de constater la réceptivité de cette huître aux deux Protozooses mais également sa sensibilité à une Haplosporidie.

Genetic parameters of production traits (growth, carcass yield, fillet yield) and bony tissues (head and vertebral axis) were estimated for large all-female rainbow trout Oncorhynchus mykiss reared in freshwater. Genetic parameters were estimated using REML at 16 months of age (1636 g) on 1962 DNA-assigned progenies from a partial factorial mating design with 60 dams and 100 sex-reversed sires. Most traits presented medium to high heritability (0.37 to 0.54). A high genetic correlation (r(A)=0.97) was found between fillet yield and headless gutted carcass yield (or HGCarc%). Due to its higher heritability and high genetic correlation with fillet yield, selection on HGCarc% should result in a 50% increase in selection efficiency on fillet yield by reducing...

Autores: Alayse, J.p.; Lahaye, J.
The experimental unit used previously in our laboratory for the study of the effect of the photoperiod on the growth of flatfish was based on the use of tanks with separate recirculation systems. We modified it, connecting the different tanks to a single, more powerful recirculation system. This new unit comprised four different parts s - a biological filtar and an ultraviolet sterilizer. - a gravity operated water distribution system. - a series of 12 rearing tanks. - a piping system connecting the tank outlets to the biological filter. The total volume of the unit was 8 900 l. 200 l were changed every week. The main advantages of this new unit was that the quality of the water supplied to all tanks could be exactly the same, and that various parameters...

Role of the Nutritional Condition of Breeding Anchovies in the Subsequent Recruitment to their Population in the Bay of Biscay (NE Atlantic)
Provedor de dados: 5
Autores: Bergeron, Jean-pierre; Masse, Jacques.
The recruitment of marine fish populations is a central concern of fisheries scientists. Multiple research pathways have been explored, with emphasis of the causes of mortality affecting principally the early developmental stages of fish life. The small data set presented focuses on a feature often inadequately considered, i.e., the nutritional condition of the breeding parent fishes estimated from the levels of the RNA/DNA ratio determined in fish white muscle. This is applied to the European anchovy population inhabiting the French continental shelf of the North-east Atlantic Ocean. In four of the five years analysed, the annual recruitment shows a tight relationship with the mean values for the RNA/DNA ratio determined in the parent fish during the...

Bi-parental families were produced in hatchery and tested in the field in 2001. Two sets of 5 families were constituted, selected on their high (R) and low (S) survival. These two sets were reared in Brittany from March to November 2002. Samplings were performed twice a month to obtain data on biometry, survival, reproductive cycle, biochemical composition, adenylate energy charge, hemolymph parameters (ions and defense system) and muscle strength. "R" and "S" oysters exhibited different reproductive effort and spawning strategy. "R" oysters allocated less energy in gonad than "S" ones and presented a complete spawning at the end of August contrary to the "S" which spawns partially. Mortality started in July when the seawater temperature reached 19 degree...

A complementary method for production of tetraploid Crassostrea gigas using crosses between diploids and tetraploids with cytochalasin B treatments
Provedor de dados: 5
Autores: Mccombie, Helen; Ledu, Christophe; Phelipot, Pascal; Lapegue, Sylvie; Boudry, Pierre; Gerard, Andre.
We present a new method to produce tetraploid Crassostrea gigas by cytochalasin B inhibition of polar body 2 expulsion in diploid females crossed with tetraploid males. This offers a means of direct introgression of genetic characters from selected diploid to tetraploid lines, avoiding a triploid step. Offspring larval ploidy shifted over time and depended on size, with tetraploids more frequent among the smaller larvae and triploids among the large. Viable tetraploids were found at 4 and 6 months, indicating the technique was successful. The possibility that gynogenesis occurred was tested by microsatellite analysis to confirm the presence of paternally inherited alleles. These were present in all animals of the 2n x 4n + CB (female first) cross. However,...

Autores: Le Vaillant, Maryline; Viblanc, Vincent A.; Saraux, Claire; Le Bohec, Celine; Le Maho, Yvon; Kato, Akiko; Criscuolo, Francois; Ropert-coudert, Yan.
Growing evidence suggests that telomeres, non-coding DNA sequences that shorten with age and stress, are related in an undefined way to individual breeding performances and survival rates in several species. Short telomeres and elevated shortening rates are typically associated with life stress and low health. As such, telomeres could serve as an integrative proxy of individual quality, describing the overall biological state of an individual at a given age. Telomere length could be associated with the decline of an array of physiological traits in age-controlled individuals. Here, we investigated the links between individuals' relative telomere length, breeding performance and various physiological (body condition, natural antibody levels) and life...

Transcriptome based SNP discovery and validation for parentage assignment in hatchery progeny of the European abalone Haliotis tuberculata
Provedor de dados: 5
Autores: Harney, Ewan; Lachambre, Sebastien; Roussel, Sabine; Huchette, Sylvain; Enez, Florian; Morvezen, Romain; Haffray, Pierrick; Boudry, Pierre.
Selective breeding strategies require pedigree information over generations, but many species produced in aquaculture are too small to be physically tagged at early stages. Consequently, maintaining a sufficient number of separate families is often needed but costly and logistically difficult. Alternatively, parentage assignment can be obtained using DNA markers. We developed a panel of single nucleotide polymorphism (SNP) markers for the European abalone Haliotis tuberculata using an existing transcriptomic resource. An initial set of 2,176,887 SNPs was filtered to select 500 for high throughput genotyping. Of these, 298 SNPs were amplified in at least 90% of our H. tuberculata samples, consisting of a mixed family cohort (945 offspring) generated by...

Genetic improvement of hatchery propagated bivalve stocks : prospects and constraints
Provedor de dados: 5
Autores: Boudry, Pierre.
To date, the most significant genetic improvement for the production of Pacific oyster (Crassostrea gigas) has been obtained through the production of triploids, especially since the development of tetraploids. Quantitative genetics studies suggest that significant gains, for disease resistance or other traits, could be obtained in diploids. However, the limited extent of hatchery-propagation (versus natural recruitment) and/or various technical difficulties and biological characteristics of the species have retarded the development of selective breeding programs. In the U.S.A., Australia and New Zealand, family-based selective breeding programs have recently been initiated to improve growth, disease tolerance and yield.  In Europe, where both natural and...

Genetic variation and trade-offs for reproduction ans survival in the Pacific oyster Crassostrea gigas
Provedor de dados: 5
Autores: Boudry, Pierre; Degremont, Lionel; Bedier, Edouard; Pouvreau, Stephane; Normand, Julien; Ernande, Bruno.
To date, the most significant method to genetically reduce reproductive effort in the Pacific oyster (Crassostrea gigas) has been through the production of triploids, especially since the development of tetraploid lines allowing the breeding of 'natural' triploids. Gametogenesis of triploid oysters is strongly reduced compared with diploids, although they are not fully sterile and can produce viable gametes and some progenies when crossed with diploids. Reduced reproductive allocation and higher heterozygocity are commonly proposed as the main reasons why triploids often present superior yield compared with diploids. Temperature and food availability are known to favour gametogenesis in triploids, but the existence of genetic variation for this trait...

Autores: Doan, Q. K.; Vandeputte, Marc; Chatain, Beatrice; Morin, T; Allal, Francois.
Viral encephalopathy and retinopathy (VER), otherwise known as viral nervous necrosis (VNN), is a major devastating threat for aquatic animals. Betanodaviruses have been isolated in at least 70 aquatic animal species in marine and in freshwater environments throughout the world, with the notable exception of South America. In this review, the main features of betanodavirus, including its diversity, its distribution and its transmission modes in fish, are firstly presented. Then, the existing diagnosis and detection methods, as well as the different control procedures of this disease, are reviewed. Finally, the potential of selective breeding, including both conventional and genomic selection, as an opportunity to obtain resistant commercial populations, is...

Provedor de dados: 5
Autores: Akadje, C. M. A.; Amon, Y. N.; N'Da, K.; Le Loc'H, F.
To provide information for improving barracuda stock management on the Ivorian coast, the reproductive biology (length-weight relationship, sexual development and size at first maturity) of Sphyraena guachancho was studied in relation to the marine seasons and fish size classes. Samples were obtained between July 2010 and June 2011 from commercial fisheries in Abidjan fishing port. A total of 662 specimens (328 females, 334 males) with sizes ranging from 19 to 63 cm FL were analyzed. The sex ratio of Sphyraena guachancho was found to be slightly in favour of males (1: 0.98). The length-weight relationship is isometric for both sexes. The gonadosomatic index (GSI), hepatosomatic index (HSI), condition factor (K) and percentage of mature individuals for both...

First Evidence of Realized Selection Response on Fillet Yield in Rainbow Trout Oncorhynchus mykiss, Using Sib Selection or Based on Correlated Ultrasound Measurements

Autores: Vandeputte, Marc; Bugeon, Jérôme; Bestin, Anastasia; Desgranges, Alexandre; Allamellou, Jean-michel; Tyran, Anne-sophie; Allal, Francois; Dupont-nivet, Mathilde; Haffray, Pierrick.
Fillet yield, the proportion of edible fillet relative to body weight, is a major trait to improve in fish sold processed, as it has a direct impact on profitability and can simultaneously decrease the environmental impact of producing a given amount of fillet. However, it is difficult to improve by selective breeding, because it cannot be measured on live breeding candidates, its phenotypic variation is low, and, as a ratio, it is not normally distributed and a same change in fillet yield can be the result of different changes in fillet weight and body weight. Residual headless gutted carcass weight (rHGCW) is heritable and highly genetically correlated to Fillet% in rainbow trout, and can be predicted by the ratio of abdominal wall thickness to depth of...

Research and development for the genetic improvement of the Pacific oyster in France : present and prospects
Provedor de dados: 5
Autores: Boudry, Pierre; Haffray, Pierrick.
The most significant genetic improvement for the production of Pacific oyster (Crassostrea gigas) in France to date has been through the breeding of triploids, especially since the development of tetraploids. Triploid oysters commonly resist summer mortality better than diploids. This is most probably because reproductive allocation is so important in this phenomenon. Quantitative genetics studies strongly suggest that a significant gain in resistance to summer mortality, or other traits of interest, could be obtained by selective breeding. Practical difficulties however, and the high cost of breeding large numbers of families under common conditions over many generations remain major constraints to family-based selective breeding in oysters. In the last...

Autores: Cabodevila,V.G; Picardi,L.A; Pratta,G.R.
Segregating progeny from the tomato Second Cycle Hybrids (SCH) that were obtained from crossing RIL (Recombinant Inbred Lines) allows the detection of new genetic combinations that could increase genetic variability in F2 populations. The objectives of the present study were to evaluate eleven tomato quality traits in a segregating F2 population obtained from a SCH and, then, to characterize the molecular diversity by six AFLP (Amplified Fragment Length Polymorphism) primer combinations. Different multivariate analyses were used to assess the degree of concordance among these two approaches to detect genetic variability. Sixty-nine F2 plants were obtained by selfing the SCH (ToUNR18xToUNR1). The parental RIL were derived from an interspecific cross between...

The Javan leopard (Panthera pardus melas) is a distinct subspecies, basal to the phylogenetic tree of Asian leopards. At present this taxon is not specifically managed in captive breeding programs in America and Europe. As it is endangered in the wild, and represents a genetically and morphologically unique and distinct taxon we recommend a more concerted effort to target this species for captive breeding.

During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, ß-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. Four homothallic species, P. attenuata, P. flexuosa, P. formosa and P. intricata, were isolated from rhizosphere soil of healthy forests of Fagus hayatae, Quercus glandulifera, Q. tarokoensis, Castanopsis carlesii,...

Fungal species of the class Trichomycete fungi (Zygomycota) are associated with the digestive tracts of Arthropoda. The relationships between these fungi and their hosts are still little understood: they may be commensal, beneficial or deleterious. Knowledge of the community structure of parasites/ pathogens and of the habitats of each species of Culicidae larvae can be important in studies that intend to use combined approaches to population control. Larvae of Culicidae and their associated trichomycete fungi were collected in Manaus County, AM, Brazil; sampling habitats included plants (natural habitat) and anthropic containers (artificial habitats). The total of 1,518 larvae were collected, 913 of which were in natural habitats and 605 were in...

ABSTRACT We analyzed growth and reproduction of captive-born smallnose fanskates Sympterygia bonapartii. Egg cases were obtained from oviposition of two females caught in the wild and held at Temaikèn Aquarium. Following hatching, growth was analyzed in 13 females and 21 males until sexual maturity. Pattern of oviposition activity and reproductive performance were evaluated in six of the captive-reared females. Four models were fitted to growth data, among which the logistic function was the one attaining the best fit. The highest growth rate for both sexes was recorded during the first year of life, whereas growth was significantly higher in females than in males during the second year. Size at first oviposition was 61.7 ± 3.5 cm TL, similar to wild...

How does diet influence the reproductive seasonality of tropical freshwater fish?: A case study of a characin in a tropical mountain river
Provedor de dados: 83
Autores: Ballesteros,Tania M.; Torres-Mejia,Mauricio; Ramírez-Pinilla,Martha P.
Seasonal breeding of tropical freshwater fish may be synchronized with periods of high food consumption. We explored this hypothesis by studying the relationship between diet and reproductive activity of Creagrutus guanes (Teleostei, Characidae). Our results showed that C. guanes had a generalist and omnivorous diet dominated by aquatic insects (mainly Diptera larvae) and seeds. Creagrutus guanes did not show intersexual or ontogenetic variation in diet. Peaks of feeding activity during rainy months were not synchronized with breeding in dry months. Our results do not support the hypothesis that the reproductive season has to be synchronized with high food consumption. We discussed the hypothesis fat reserves may be an important factor for the...

Temporal differences in breeding site use between tits and mice
Provedor de dados: 19
Autores: Suzuki, Kei K.; Yoshida, Tomoya; Yamane, Yutaka; Shimamoto, Tatsuki; Furukawa, Ryuji G.; Yanagawa, Hisashi.
Describing the interactions among cavity breeders is key to understanding their breeding ecology. In this study　the temporal difference in cavity use between the great tit, Parus major (Linnaeus, 1758) and the small Japanese field mice, Apodemus argenteus (Temminck, 1845) is investigated, as a first step for clarifying the interaction between bird and mammal cavity breeders. Forty-seven nest boxes were installed on tree trunks in two urban forests of Hokkaido Island, Japan, and the breeding nests of tits and mice were found in 34 and 11 boxes, respectively. The tits used the nest boxes throughout the breeding season, from May to July. In contrast, mice breeding nests were found in the last half of the breeding season, from July to October. Our results...

Larval mosquito fauna (Family Culicidae) of Sta. Ignacia,Tarlac,Province,Philippines
Provedor de dados: 19
Autores: Santiago, A. T. A.; Claveria, Florencia G.
Surveillance of the presence of larval mosquitoes was performed in the suburban municipality of Sta. Ignacia, Tarlac Province, Philippines, with approximately 94.0% of the land area still devoted to agriculture. Five districts were covered, namely: Macageuing, San Francisco, San Vicente, Sta. Ines Centro, and Sta. Ines East. The standard dipping method was used to collect mosquito larvae from rice fields, ponds, creeks, streams and used tires and larvae were identified at the genus level. Culex sp. was the most abundant with a calculated mean breeding index of 22 larvae per dip. Anopheles sp. and Aedes sp. were likewise identified with mean breeding indices of five and two larvae per dip, respectively. In two samplings, Culex sp. had the highest mean...

Some Aspects of Sea Cucumber, Holothuria scabra (Jaeger, 1935), along the Coast of Dar es Salaam
Provedor de dados: 20
Autores: Kithakeni, T.; Ndaro, S.G.M.
Some aspects of the biology of the sea cucumber Holothuria scabra Jaeger, 1935 were studied along the coast of Dar es Salaam. Samples of Holothuria scabra were collected from Kunduchi and Buyuni between January and December 1999. The abundance of Holothuria scabra was higher in Buyuni (3951) than in Kunduchi (1176). However, the level of exploitation per year from far reefs was higher in Kunduchi than in Buyuni. Sea cucumber harvesting by villagers is done monthly on intertidal areas and from reef flats near to the villages. Higher catches from Buyuni were recorded during August and November (perhaps due to light winds such that trips could be made to far-off reefs), while the catch from Kunduchi was relatively low throughout a year. The length- frequency...

Prediction of grain yield of spring barley varieties by disease and growth characteristics from VCU testing
Provedor de dados: 21
Autores: Østergård,  H.; Kristensen, K.; Jensen, J.W.
Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied much within and between environments (years and sites) and systems. Further, the variation between varieties was substantially and it differed between different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model for predicting the observed grain yield each year from these characteristics the previous year was found. In this model, the...

Simultaneous epidemic development of scald and net blotch on single leaf layers of a spring barley crop
Provedor de dados: 21
Autores: Vollmer, J.H.; Pinnschmidt, H.O.; Munk, L.; Østergård, H.
Background and objectives  Two pathogens growing on the same leaf compete for the same resources, i.e. space and plant nutrients. This may lead to density dependent disease development. The pathogens may also influence each other directly such that the influence of one on the other is more complex than a simple function of the area of the other pathogen. Different interaction types are, for example, competition, mutualism and exploitation. The importance of such interactions for epidemics of simultaneously occurring pathogens has received little attention. The objective of this study is to investigate the simultaneous epidemic development of Rhynchosporium secalis (causing scald) and Drechslera teres (causing net blotch) on spring barley under field...

Sortenvergleich Zuckermais - Neue Öko-Zuckermais-Sorten in Sicht
Provedor de dados: 21
Autores: Regnat, Rudolf.
Am Kompetenzzentrum für ökologischen Gemüsebau in Bamberg (Bayr. Landesanstalt für Wein- u. Gartenbau) fand 2008 ein Vergleichsanbau von 20 supersüßen und zwei normalsüßen Sorten Zuckermais statt. Weltweit gibt es nur fünf Züchter von Zuckermais, von denen sich vier in den USA befinden. In Anbetracht der räumlichen Konzentration der konventionellen Maiszüchtung und der dadurch steigenden Gefahr der gentechnischen Verunreinigung galt den fünf Sorten aus Ökozüchtung (dabei Probesaatgut von drei Sativa-Selektionen) ein besonderes Interesse. Bewertet wurden marktfähiger Ertrag und Süße.

Stability of variety mixtures of spring barley
Provedor de dados: 21
Autores: Østergård, H.; Kristensen, K.; Jensen, J.W.
Six 3-component variety mixtures of spring barley and their component varieties have been grown in 17 different environments (3 years, 3 locations, 3 different growing systems). For three of the six mixtures, the grain yield was significantly higher than the average yield of its components; in none of the mixtures it was significantly lower. The variation in grain yield over environments of all variety mixtures was compared to the variation of all component varieties. The six mixtures were on average more stable than the 14 component varieties grown in pure stands with respect to actual yield as well as to rank values of yield.

Evolutionary breeding of wheat for low input systems
Provedor de dados: 21
Autores: Wolfe, Prof Martin S.; Hinchsliffe, Miss Kay S.; Clarke, Dr Sarah M; Jones, Dr Hannah; Haigh, Miss Zoe; Snape, Prof John; Fish, Dr Leslie.
Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure varieties. They are formed by assembling seed stocks with diverse evolutionary origins, recombining these stocks by hybridisation, bulking the F1 progeny, and subsequent natural selection of the progeny in suc-cessive natural cropping environments. CCPs derived from either 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK. The YCCPs out yielded the QCCPs, which had higher protein concentrations and Hagberg falling numbers. Although the CCPs performed within the range of the parents, they often performed better...

Nutrient use efficiency and arbuscular mycorrhizal root colonisation of winter wheat cultivars in different farming systems of the DOK long-term trial
Provedor de dados: 21
Autores: Hildermann, Isabell; Messmer, Monika; Dubois, David; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
BACKGROUND: For organic farming, cultivars are required with high nutrient use efficiency under nutrient limited conditions. Arbuscular mycorrhizal fungi (AMF) are known to contribute to nutrient uptake under low input conditions. We compared nutrient use efficiency (NUE) of old and modern organically and conventionally bred cultivars in organic and conventional systems and assessed AMF-root colonisation (AMF-RC) in relation to nutrient concentrations.    RESULTS: Cultivars and systems had a statistically significant effect on nitrogen (N) and phosphorus (P) concentrations and NUE parameters, whereas no genotype × environment interactions appeared. In contrast to N and P uptake, the NUE parameters were higher under organic than under conventional...

Seedling root and shoot growth in hydroponics and allelopathic activity using a bioassay have been studied in very diverse populations of winter wheat grown under either organic or conventional conditions for a number of generations and subjected only to natural selection. The study was conducted on seeds from generation 6 (F6) and 11 (F11) from three composite cross populations (CCPs) produced by the Organic Research Centre in the UK. Since the F5 the populations were maintained under organic and conventional conditions in Germany. Two parallel populations were created from each CC, resulting in a total of six organic and six conventional CCPs. The sets of parallel populations showed similar evolutionary trends indicating that the observed changes are...

Autores: Friedel, Jürgen K.; Gollner, Manfred; Hrbek, Regina; Jakupaj, Shpresa; Flamm, Clemens; Oberforster, M.; Zechner, E.; Kinastberger, A.; Löschenberger, F.
The root length density, arbuscular mycorrhizal (AM) colonisation and the total AM root length density of 12 winter wheat cultivars have been studied at seven sites in eastern Austria under organic farming. Root length density did not differ between the cultivars whereas AM colonisation and total AM root density did. Site effects were more pronounced than cultivar effects. All three traits generally were on a higher level in calcaric Phaeozems than in Cambisols. The AM colonisation and total AM root density decreased with increasing plant height and were positively correlated with crop yield. On calcaric Phaeozems, root length density in the subsoil was obviously more important for drought tolerance than AM colonisation in the topsoil.

Screening alternativer Leguminosenarten auf ihre Eignung zur Gründüngung und zum Mischanbau im ökologischen Landbau
Provedor de dados: 21
Autores: Baresel, J. P.; Reents, H.J.; Schenkel, W.
In diesem, auf zwei Jahre angelegtem Projekt wurden in 3 Feldversuchen 427 Akzessionen von insgesamt 56 Arten einjähriger Leguminosen auf ihre Eignung als Gründüngungspflanze, insbesondere als Bodenbedecker in speziellen Mischanbausystemen, sogenannte Lebendmulch-("Living Mulch") Systeme in Deutschland geprüft. Dabei handelte es sich zum größten Teil um Wildpopulationen und zum geringerem Teil um Zuchtsorten. Die Herkunftsgebiete liegen in erster Linie im Mittelmeerraum, da hier die biologische Diversität am höchsten ist. In Mittel- und Nordeuropa sind geeignete Arten nur sehr selten. Im Vordergrund der Evaluierungen standen neben der Akklimatisierbarkeit morphologische Eigenschaften (Habitus und Dichte ) die Dauer des Entwicklungszyklus, Biomassebildung...

Schwefelgehalte, Proteinfraktionen und Kleberzugfestigkeit von Weizen – Ergebnisse eines Ringversuchs biologisch-dynamischer Züchter
Provedor de dados: 21
Autores: Hagel, Ingo; Haneklaus, Silvia; Schnug, Ewald.
Schwefelmangel führt bei Weizen zu erheblich festeren Teigen. Daher kollidierte in den 80er Jahren unvorhergesehen das Zuchtziel einer Steigerung der Backqualität durch eine Straffung der Proteinstruktur mit einer exogen bewirkten zusätzlichen Verfestigung der Proteinmatrix infolge drastisch reduzierter Schwefeleinträge in die Ökosysteme. Eine S-Düngung führte dann auch zu einer Steigerung des Backvolumens. Und zwar nicht weil die Kleber der modernen Weizensorten zu weich, sondern weil sie durch die Züchtung bereits zu stark verfestigt waren und den neuen Umweltverhältnissen nicht mehr angepasst waren. Die hohe technologische Qua-lität dieser Sorten kann daher als Resultat eines züchterisch unbewusst induzierten S-Mangels angesehen werden, denn sie weisen...

Predicting spring barley yield from variety-specific yield potential, disease resistance and straw length, and from environment-specific disease loads and weed pressure
Provedor de dados: 21
Autores: Østergård, H.; Kristensen, K.; Pinnschmidt, H.O.; Hansen, P.K.; Hovmøller, M.S.
Abstract For low-input crop production, well-characterised varieties increase the possibilities of managing diseases and weeds. This analysis aims at developing a framework for analyzing grain yield using external varietal information about disease resistance, weed competitiveness and yield potential and quantifying the impact of susceptibility grouping and straw length scores (as a measure for weed competitiveness) for predicting spring barley grain yield under variable biotic stress levels. The study   comprised 52 spring barley varieties and 17 environments, i.e., combinations of location, growing system and year. Individual varieties and their interactions with environments were analysed by factorial regression of grain yield on external variety...

Virulence pattern in Danish races of common bunt (Tilletia caries) Common Bunt
Provedor de dados: 21
Autores: Borgen, Anders.
Spores of common bunt (Tilletia caries) was sampled from different places in Denmark in 2000-2005 and maintained as a bulk sample on susceptible varieties. In 2011 and 2012, spores were harvested from selected infected varieties, and used to reinoculate the same variety from where they were harvested. 98 out of 240 tested varietes had an increase of infection from this inoculation method compared with infection from the bulk spore sample. This is interpreted as a sign of virulence development. Using this method on the differential varieties for bunt resistance and other varieties with known bunt resistance genes indicated that virulence races were present able to infect varieties having resistance genes Bt-1, Bt-2, Bt-3, Bt-4 Bt-5, Bt-7, Bt-8, Bt-10 and...

Autores: Haigh, Z E L; Clarke, S; Hinchsliffe, K; Jones, H; Wolfe, M S.
The aim of the project is to use an ecological approach to analyse the interactions of a range of key agronomic variables in organic wheat production (wheat genotype, spatial arrangement of seed, seed density and wheat/white clover bi-cropping) to determine an optimal approach to improved and stabilised production. The fi rst set of data revealed that seedling competition was infl uenced by seed rate and drilling arrangement. Furthermore, the variety Hereward had increased emergence and establishment to Aristos. An interaction exists between wheat variety, seed rate and drilling arrangement on the level of canopy cover at different developmental stages – these factors are important for the suppression of weeds. The input of farmers in the selection of...

Provedor de dados: 21
Autores: Rau, Florian; Weier, Ulrike; Krebs, Kurt-Ernst; Jahn, Marga.
Teilversuch 1  Die Ergebnisse des ersten Versuchsjahres zeigen, dass es Unterschiede im Befall des Saatgutes mit  Möhrenschwärze (Alternaria dauci) und Sortenunterschiede im Auftreten der Krankheit auf dem Feld gibt. Ob die unterschiedlichen Befallsstärken auf dem Feld auf einen unterschiedlich starken Ausgangsbefall des Saatgutes zurückzuführen sind muss weiter geprüft werden.   Das Ertragspotential der Sorten war unterschiedlich, die stärksten Sorten erreichten etwa den doppelten Ertrag der schwächsten Sorte.  Starke Laubschädigungen durch Alternaria führten tendenziell zu erhöhten Nitratgehalten im Erntegut. Hier kann – je nach Vermarktungsweg – eine frühere Ernte für die Praxis empfehlenswert sein.

Yield of spring barley mixtures as a function of varietal and environmental characteristics
Provedor de dados: 21
Autores: Kiær, Lars; Skovgaard, Ib; Østergård, Hanne.
To design good variety mixtures it is important to understand the influence of varietal and environmental characteristics on mixing effect, e.g. what characteristics are more beneficial when all mixed varieties express it highly and what characteristics are more beneficial when the mixed varieties express it to varying extent. However, as it is generally impossible to manage more than a few experimental combinations in each field trial, information on general relationships and factors of importance for the successful design of variety mixtures may be overlooked. Using meta-regression (e.g. Houwelingen et al. 2002), numerous results of such trials can be combined, and the influence of varietal and environmental factors on mixing effect can be elucidated....

Evaluierung von Brassicaceae auf Resistenz gegen die Mehlige Kohlblattlaus (Brevicoryne brassicae) als Basis zur Nutzung blattlausresistenter Kohlsorten für den ökologischen Landbau
Provedor de dados: 21
Autores: Bundesanstalt für Züchtungsforschung an Kulturpflanzen, Institut für Epidemiologie und Resistenz.
Die Mehlige Kohlblattlaus ist sowohl im konventionellen als auch im ökologischen Landbau ein wirtschaftlich bedeutender Schädling des Gemüsekohls. Im ökologischem Anbau ist die Bekämpfung der Blattlaus sehr schwierig, gleichzeitig hat aber in den vergangenen Jahren der Befallsdruck infolge der Ausweitung des Rapsanbaues als nachwachsender Rohstoff zugenommen. Daher ist es notwendig, Gemüsekohlgenotypen mit Blattlausresistenz zu finden bzw. mögliche Resistenz im Rahmen der ökologischen Züchtung in die Sorten zu übertragen. Bisher sind keine vollständig resistenten Sorten bekannt, lediglich graduelle Unterschiede im Befall  wurden gefunden. In Gewächshausprüfungen wurden aus 275 evaluierten Genotypen 20 selektiert, auf denen nach 14 Tagen die...

Orsaker till skillnader i produktion och beteenden i olika inhysningsformer för värphöns har till stor del en genetisk bakgrund.

Olika genotyper visade sig från produktionssynpunkt reagera lika på förändringar i fodersammansättning, men olika från djurhälso- och beteendesynpunkt. Med de näringsmässigt strängare KRAV-regler som förespeglas träda i kraft 2001 krävs från djurskyddssynpunkt sannolikt andra genotyper, men kraven riskerar att bli högre ställda än vad som är biologiskt möjligt att uppfylla.

Autores: Hein, Lisa; Buitenhuis, Albert Johannes; Gregersen, Sandra Beyer; Larsen, Lotte Bach; Demirovic, Dino; Warnecke, Solveig; Nielsen, Niels Henning; Munk, Arne; Sørensen, Lars Peter; Pedersen, Jørn; Kargo, Morten.
The fatty acid (FA) composition of bovine milk may be related to human health and technological properties of dairy products. The FA composition can be altered both through management and breeding. Large scale FA profiling of the Danish dairy cattle population has now been implemented for more than a year. For the first time access to millions of FA observations across an entire dairy population enables in depth analysis of the factors affecting the FA profile of milk. This was the aim of this study. For 12 months more than 3.5 million milk samples from four Danish dairy breeds had been analyzed using mid infrared spectroscopy and application of FOSS Application Note 64 for predicting content of seven FA groups and four individual FA. The results showed...

How to select varieties for organic farming: science and practice
Provedor de dados: 21
Autores: Hoad, S P; Davies, D H K; Topp, C F E.
Selection of cereal varieties suited to organic farming requires a different, but complementary, approach to that used when developing cereals for conventional high input systems. Selection is based on the interaction between a series of desirable plant and crop characteristics, in particular competitive ability against weeds. Certain key characteristics that are generically desirable for organic cereal varieties include: (1 good establishment ability, (2) high tillering ability, (3) increasing plant height, (4) planophile leaf habit, (5) high leaf index and (6) robustnesses in yield performance across sites. Our data strongly suggest that high crop ground cover is the most important feature for creating a highly competitive crop that also has consistency...

Cereal breeding strategies for organic and low-external-input crop production systems
Provedor de dados: 21
Autores: Acikgoz, Prof. Dr. Nazimi; Ilker, Dr. Emre.
Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions.   Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars.  Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic...

Dem Ökologischen Landbau stehen derzeit keine richtlinienkonformen Verfahren mit ausreichender Wirksamkeit und/oder arbeitstechnischer Effizienz zur Verfügung, um die gesetzlichen Auflagen in der Saatgut-Produktion einzuhalten. Schon mehr als drei bzw. fünf an Flug- und/oder Hartbrand erkrankte Ähren pro 150 qm in der Basis- bzw. Z-Saatguterzeugung führen zur Aberkennung der Vermehrungsbestände und somit zu beträchtlichen finanziellen Einbußen. Einen Ausweg böte der Anbau von resistenten Sorten. Hierzu wurden 2002-03 und 2004-05 die verfügbaren Handelssorten auf ihre Anfälligkeit gegenüber Hartbrand und seit 2000 insgesamt 274 Wintergerste-Genbankmuster bzw. Handelssorten gegenüber Gerstenflugbrand geprüft.

Bei mehrjähriger Vermehrung von Wintergerste nach ökologischen Richtlinien muss beim Anbau von anfälligen Sorten mit einem Auftreten von zunehmendem Brandbefall gerechnet werden. Einen Ausweg böte der Anbau von resistenten oder teilresistenten Sorten. Eine verlässliche Testung der Resistenzen gegen Brandkrankheiten benötigt mindestens zwei Prüfzyklen, weshalb bei der Vielzahl neu zugelassener und wegfallender Sorten Kenntnislücken nicht zu vermeiden sind.

In Organic Agriculture, cultivation environments and agronomic practices are very diverse. This diversity can be handled with decentralized selection based on the knowledge of farmers and scientists. A collaborative work between associations from Réseau Semences Paysannes and the DEAP team from INRA du Moulon set up an innovative breeding approach on farm based on decentralization and participation of farmers.  This approach makes it possible to (i) create new population varieties of bread wheat locally adapted (genetic innovation) (ii) set up an organizational scheme based on decentralization and co construction between actors (societal innovation) and (iii) develop experimental designs, create statistical and data management tools which stimulate these...

Identification and quantification of ‘Candidatus Phytoplasma pyri’ in declining trees of a Swiss cider pear orchard after incision treatment at the stem base
Provedor de dados: 21
Autores: Toenshoff, E. R.; Brunner, H.; Tamm, L.; Schärer, H.-J.; Oberhänsli, T.
Candidatus Orchards of 30 to &gt;100 years old fruit trees used for cider production are endangered by an accumulation of abiotic and biotic stress factors. Among biotic stress factors, diseases such as pear decline (PD) caused by the bacterial pathogen ' Phytoplasma ' contributes to a weakening and reduced life time of affected trees. Since direct treatment of this disease is not possible, approaches have gained attention, which might lead to an increased resilience against this pathogen, such as incisions of the cambium at the graft union at the stem base. Six 35 years old pear trees () of a Swiss cider production orchard, all affected by mild decline were chosen for this study. Four out of them were treated with 2-4 incisions per tree in February 2016....

Lamb Production:grazing management, breeding policy and parasite control
Provedor de dados: 21
Autores: Hanrahan, J.P.; Good, Barbara.
Internal parasitic infection can pose major health problems in young livestock and this is particularly so in the context of lambs in organic production systems. In the context of sheep production on an organic farm the challenge to control parasite infection is especially difficult in situations where crop production is absent or a minor element of the whole farm system. Our investigations, to date at Athenry, have concerned an exploration of lamb production in an all-grass farming setting with particular attention being paid to the breeds employed and the seasonal patterns of gastrointestinal parasite challenge. This flock (about 110 ewes plus replacements) is wintered indoors and lambs in early March each year.

Effects of conventionally bred and Bacillus thuringiensis  (Bt) maize varieties on soil microbial biomass and activity
Provedor de dados: 21
Autores: Fliessbach, Andreas; Messmer, Monika; Nietlispach, Bruno; Infante, Valentina; Mäder, Paul.
Abstract  Genetically modified (GM) maize containing genes from the soil bacterium Bacillus thuringiensis (Bt) was cultivated on 29% of the total maize production area worldwide in 2009. Most studies to date compare Bt-maize varieties with their near isogenic lines; however, there is little information on the variability of conventional maize breeding lines and how the effects of Bt varieties are ranked within. In our study on the potential risks of Bt-maize varieties, we analyzed tissue quality and compared the effects of ten conventional and GM maize varieties on soil microbiological properties in a replicated climate chamber experiment. All maize varieties were cultivated twice in the same soil microcosm. Shoot yields and soluble C in leaf tissue of Bt...

Autores: Maghirang, Rodel; Rodulfo, Gloria; Madrid, Ivy Jane; Ferry, Elmer; de la Cruz, Carlos; Vilbar, Lorna; Misterio, Jocelyn.
Development of organic vegetable varieties was done through participatory breeding in Regions 4A, 4B, 8 and 12 in the Philippines. Farmer co-operators were trained and seeds of segregating lines and populations which served as their starting materials were provided to them. The materials were evaluated in their respective farms along with continuous selection and seed production. Co-operators were able to select lines of various vegetable crops and seed produce them.

Heritabilität und Korrelationen von Morphologischen Eigenschaften bei Winterweizen-Sorten unter Bio-Bedingungen
Provedor de dados: 21
Autores: Knapp, Samuel; Rosalie, Aebi; Martin, Anders; Hiltbrunner, Jürg.
Die untersuchten morphologischen Merkmale weisen insgesamt eine niedrigere Heritabilität und eine geringe Korrelation mit Kornertrag auf. Dies weist darauf hin, dass sich diese Merkmale nur bedingt als Selektionsmerkmal und zur Sortenbeschreibung eignen. Aber auch wenn nur ein geringer positiver Zusammenhang mit dem Kornertrag erkennbar ist, kann sich z.B. ein höherer Bodenbedeckungsgrad auf lange Frist die Menge der Unkrautsamen im Boden verringern. Der positive Zusammenhang von Pflanzenhöhe und Ertrag ist teilweise durch eine bessere Gesundheit hoher Pflanzen zu erklären.

Marker für die Zulassung von Maispopulationssorten
Provedor de dados: 21
Autores: Büttner, B.; Eder, B.; Eder, Joachim; Schweizer, G.
The genetic resource of adapted German maize landraces is threatened to get lost. Unsolved admission standards at the Federal Office for Plant Varieties are a main obstacle for breeders to use such material. Until now each application for admission has been rejected due to missing homogeneity. Therefore, population specific marker alleles should be developed and deposited at the Federal Office for Plant Varieties as further selection criteria. A first step is the development of markers for phenotypic apparent traits. We developed three markers for red and white cob glume color and used them for selection of two maize populations. The next step would be the development of non-genic markers. Although these markers have no phenotypic effects they also do not...

Video: Improving health in native dual-purpose cattle (2-Org-Cows)
Provedor de dados: 21
Autores: Alföldi, Thomas.
The principle of organic breeding is to adapt the cow towards the local and natural production system. The one-sided genetic selection, preferring increased milk yield, complicates feeding and management of modern Holstein genetics when confronted with the strict rules defined for organic milk production. This requires a reformulation of existing dairy cattle breeding goals, or the utilization of alternative and locally adapted breeds that historically emphasized functionality, robustness, and longevity.  In this video, Maria Jaeger and Sven König, both from the University of Kassel, explain how the characterization of pasture based production systems, novel data recording, and genetic evaluations will lead to optimized breeding programs for dual-purpose...

Organic tree propagation under Welsh nursery conditions

Autores: Frost, David; Clarke, Aldwyn.
The demand for organically raised tree and hedging plants had been reported from organic farmers in Tir Gofal, as well as within the landscaping industry. Although there are a number of plant raising nurseries producing organically raised plants for vegetable and fruit production, there are no tree nurseries producing to organic standards. Nursery tree growers were concerned that there was currently too little known about the performance of tree seedlings in organic substrates (e.g. in root-trainers), nor about the nutrient supply to seedlings under organic regimes, nor about diseases control (especially fungal diseases such as mildew).  Therefore, the development of three hedging species; Hawthorn, Hazel, Blackthorn, were tested for two growing systems in...

Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure line varieties. They are formed by hybridising lines with diverse evolutionary origins, bulking the F1 progeny, and allowing natural selection of the progeny in successive crop environments. CCPs derived from 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK; they are currently (2006) in F5. The YCCPs out yielded the QCCPs, which had better quality characteristics. Although the CCPs performed within the range of the parents, the values obtained were often better than the mean of the parents. Some population...

Durch ihren hohen Proteingehalt und tiefen Nährstoffbedarf ist die Weisse Lupine (Lupinus albus) eine nachhaltige europäische Alternative zum gegenwärtig massiven Sojaimport für Futter und Nahrung. Der Lupinenanbau ist jedoch durch die Brennfleckenkrankheit Anthraknose, verursacht durch den saatgutbürtigen Pilz Colletotrichum lupini, stark eingeschränkt. Schon ein geringer Saatgutbefall kann zum totalen Ertragsausfall führen. Für einen erfolgreichen Anbau der Weissen Lupine ist es daher wichtig, Resistenzquellen zu finden.

Autores: Kennedy, T.; Merfield, C.; Mahon, T.
An organic rotation trial was established at Oak Park in 2000. The crop sequence in the seven year rotation was: two years grass-clover, winter wheat, potatoes, winter oats, lupins and spring barley. The grass-clover, which supplies nitrogen to the system, also provides vegetation which of late is cut and mixed with cereal straw to produce compost. The compost replaced sheep manure which was available up to 2007. Manure was applied to potato plots prior to cultivation for the period 2002 to 2007 and to barley plots from 2005 to 2007. The average yield of crops over the period of the rotation was: winter wheat 5.9 t/ha, potatoes 32.7 t/ha, winter oats 5.8 t/ha, lupins 2.4 t/ha and spring barley 4.5 t/ha.

Farmer's Eye and Breeder's Eye - Fields of Knowledge Exchange as a Condition of a Participatory Breeding Approach
Provedor de dados: 21
Autores: Timmermann, Martin.
With the change to organic agriculture, the diversity of local conditions becomes more important. Local adapted varieties are necessary. But breeding  for this demand is not profitable for a conventional breeding strategy. An alternative can be a participatory breeding approach (PPB). Evolved in the  context of international development cooperation, this approach is increasingly discussed in the European context.  Communication between farmers and breeders is a key issue in participatory breeding. Farmer`s and breeder`s eye have different perspectives on the  plants and different knowledge gained through experience. Those perspectives and experiences need to be exchanged. As an outcome of the  investigation of “The breeder`s eye” on the example of the...

Evolutionary plant breeding for low input systems
Provedor de dados: 21
Autores: Phillips, Scott; Wolfe, Martin.
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases.  An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural  election for mass sorting of the progeny in successive natural cropping environments. Composite cross...

Autores: Horneburg, Bernd; Becker, Heiko.
Linsen gehören zu den ältesten Kulturpflanzen in der mitteleuropäischen Landwirtschaft, ihr Anbau ist aber seit etwa 50 Jahren in Deutschland nahezu völlig erloschen. Seit einigen Jahren ist jedoch im ökologischen Landbau ein zunehmendes Interesse am Linsenanbau zu beobachten. Linsen können auf Grenzertragsböden angebaut werden und Fruchtfolgen im ökologischen Landbau erweitern. Um den Anbau zu fördern wird am Institut für Pflanzenbau und Pflanzenzüchtung der Universität Göttingen im Auftrag des BMVEL ein Leitfaden für Anbau, Nutzung und On-farm Bewirtschaftung der Linse im ökologischen Anbau erstellt. Die Broschüre beinhaltet die Kapitel 1. Die Linse – Gestern und heute, 2. Der Anbau der Linse, 3. Sortenwahl, 4. Saatgutproduktion im Betrieb und 5....

Einsatz moderner Züchtungsstrategien zur Verbesserung der Eigenschaften von Sommerbraugerste für den ökologischen Landbau
Provedor de dados: 21
Autores: Herz, Markus; Aschenbach, Birte; Müller, Karl-Josef.
Sommergerste ist im ökologischen Landbau nach Weizen, Hafer und Dinkel die Getreideart mit der höchsten Bedeutung für die verarbeitende Industrie. Der Markt für Öko-Braugerste ist in den letzten Jahren rasch gewachsen. Der gestiegenen Nachfrage steht ein knappes Angebot aus deutscher Erzeugung gegenüber, so dass viele Mälzereien zu Importen gezwungen sind. Voraussetzung für eine stärkere Verbreitung des Sommergerstenanbaus im ökologischen Landbau ist die Bereitstellung geeigneter Sorten. Für die Sommergerste sehen Vertreter der Ökolandbau-Beratung einen hohen Bedarf an Züchtung und Züchtungsforschung. Resistente Sorten haben im Ökolandbau besonders große Bedeutung.  Im Rahmen des Projektes konnten unter konsequenter Anwendung von Strategien der...

Open Pollinated Broccoli Genotypes: Agronomic Parameters and Sensory Attributes
Provedor de dados: 21
Autores: Wolf, Stefanie; Zikeli, Sabine; Fleck, Michael; Graeff-Hönninger, Simone; Claupein, Wilhelm.
Breeding of open pollinated (OP) varieties for organic farming gains further importance as varieties created by breeding techniques like CMS-hybridisation and cell fusion are no longer accepted by several organic farming associations. For broccoli (Brassica oleracea var. italica), the availability of OP varieties is very limited and the ones available are often not suitable for commercial crop production. In a participatory breeding project of the non-governmental, non-profit German association Kultursaat e.V. and the University of Hohenheim new genotypes were tested for agronomic parameters in field trials and sensory traits of cooked and raw broccoli were evaluated by two untrained consumer panels in 2012 and 2013. Agronomic traits of hybrids and OP...

Entwicklung und Praxiserprobung eines neuen Züchtungskonzeptes für einen stabilen ökologischen Salatanbau
Provedor de dados: 21
Trotz steigender Nachfrage nach Salaten aus dem „Bio-Sektor“ stagniert der heimische Anbau. Grund ist die fehlende Anbausicherheit. Krankheiten wie der Falsche Mehltau und abiotische Schadfaktoren führen häufig zu starken Ertragsverlusten. Auf dem Markt fehlen Sorten, die eine große Anbausicherheit im ökologischen Anbau mit einer guten Produktqualität vereinen. In den BÖLN-Projekten 2810OE064/069 wurden erstmals neue Züchtungsmethoden erprobt. Dabei zeigte sich, dass die Arbeit mit Kreuzungspopulationen und der Anbau von Liniengemischen geeignete Lösungswege sind, um Ertragsstabilität zu erreichen. Möglich wird dies durch eine höhere Variabilität durch die Durchmischung des Bestandes bzw. die Genetik, wodurch eine variablere Reaktion auf Stressoren gegeben...

Varieties of field vegetables and potatoes for organic production and marketing OF0304
Provedor de dados: 21
Autores: Unspecified,.
The objectives of the work were to investigate the suitability of selected varieties of vegetables and potatoes for organic production using organic or untreated seed on certified organic sites.     Organic growing of vegetables and potatoes imposes restrictions on the treatments which growers can apply to crops to maximise yield and maintain quality.  Hence choice of variety is more critical in organic situations than for conventional crops where problems can be solved at a later date by application of pesticides or fertilisers.  Varieties are needed that can respond to the sometimes sub optimum conditions that are imposed by the restrictions of organic systems and identification of these are not always evident from trials under conventional conditions....

Strategien zur Bekämpfung von Brandkrankheiten bei Getreide im Ökologischen Landbau
Provedor de dados: 21
Autores: Spieß, H.; Lorenz, N.; Müller, K.-J.; Koch, E.; Wächter, R.; Jahn, M.; Waldow, F.; Vogt-Kaute, W.; Wilbois, K.-P.
Getreidebrände als saatgutübertragbare Erkrankungen der Ähre haben im Ökologischen Landbau stärkere Bedeutung erlangt, weil eine Beizung mit hochwirksamen Fungiziden unterbleibt. Eine Bekämpfung ist jedoch zwingend notwendig, weil in der Regel Ertragseinbußen eintreten und die Sporen toxikologisch bedenklich sind. Zudem droht der Saatgutvermehrung Schaden, denn bereits mehr als drei bzw. fünf befallene Pflanzen pro 150 m² führen zur Aberkennung des Basis- bzw. Z-Saatgutes. Resistente Sorten stehen kaum zur Verfügung, denn wegen der Saatbeizung bestand für die Züchtung seit Jahrzehnten keine Notwendigkeit, sich einer Resistenzzüchtung zu widmen. Das spiegelt sich auch in den Zulassungskriterien des Bundessortenamtes wider, wo die Anfälligkeit der Sorten auf...

Quantifying resistance and lifestyle assessments of Colletotrichum in lupin
Provedor de dados: 21
Autores: Alkemade, Joris; Messmer, Monika M.; Finckh, Maria R.; Vögele, Ralf T.; Hohmann, Pierre.
Currently Europe imports large amounts of unsustainably produced soy to meet the plant-based protein demand of the feed and food industry. The high protein content and low nutrient requirements of white lupins make them a sustainable local alternative. However, lupin cultivation is severely impaired by anthracnose disease, caused by the seed- and air-borne fungus Colletotrichum lupini. Low levels of seed infestation can already lead to complete yield loss. Understanding the pathogen’s lifestyle and identifying sources of resistance are therefore of major importance to make the re-introduction of white lupin a success. Resistance screening was performed under controlled conditions. Disease severity was scored visually and qPCR was performed on inoculated...

Provedor de dados: 21
Autores: Horneburg, Dr. Bernd; Becker, Prof. Heiko.
Does regional organic screening and breeding make sense? To answer this question we looked for experimental evidence in an organic outdoor tomato project. Potentially suitable varieties were collected, genotype x environment interactions were investiga-ted and selection was carried out within three crosses at three farms in Central and Northern Germany. The resulting selections were compared at all farms. Screening within organic horticulture was the most important means of finding suitable varieties. After three years of evaluation, 71% of the 18 most successful varieties came from colleagues within organic horticulture. The analysis of the regional evaluation did not reveal strong interactions of varieties and locations. The rate of Phytophthora (late...

Zwiebelproduktion über Steckzwiebeln: Die Qualität des Pflanzguts entscheidet für den Ertrag
Provedor de dados: 21
Autores: Koller, Martin.
Im Bioanbau hat der Anbau von Zwiebeln über Steckzwiebel immer noch eine grosse Bedeutung. Zwar eignet sich die Kulturweise gut für den Bioanbau, da die Unkrautbekämpfung im Vergleich zu anderen Zwiebelanbausystemen einfach ist, aber die Schalenfestigkeit und die Lagerfähigkeit der Zwiebeln aus der gesteckten Kultur ist oft mangelhaft. Ziel der durchgeführten Versuche war, neue und bekannte Sorten auf diese Eigenschaften zu prüfen.  Das FiBL hat in Zusammenarbeit mit Bioproduzenten im Jahr 2005 an zwei Standorten Versuche durchgeführt. Getestet wurden Standardsorten sowie Jetset aus zwei Herkünften, eine neue Sorte und zwei Säzwiebelsorten, die im Vorjahr als Steckzwiebeln produziert wurden.

Breeding for nitrogen use efficiency in organic wheat systems
Provedor de dados: 21
Autores: Dawson, J.C.; Murphy, K.M.; Jones, S.S.
Improving crop nitrogen use efficiency (NUE) is important to reducing the environmental impacts of agriculture, for both perennial and annual crops. This study tested winter wheat breeding lines developed in organic and conventional systems, historic wheat varieties and perennial wheat under organic management.  There were significant differences among selection categories and among genotypes. However, standard methods of measuring NUE may not be appropriate when the breeding objectives are to reduce N use.  Alternative methods of evaluating breeding materials, including regression analysis of grain protein deviation (GPD) and principal component analysis (PCA) were explored.  GPD was not found to discriminate well between genotypes in this study, but PCA...

The overall goal of the project, which has been started in spring 2015, is to improve productivity of narrow-leafed sweet lupin (Lupinus angustifolius) and yellow sweet lupin (L. luteus) with regard to kernel yield, yield stability, and seed composition. In addition, the question shall be addressed whether the narrow genetic basis of current breeding materials may be broadened by including genebank accessions as plant genetic resources. Another task is to optimize lupin cultivation systems for non-chemical weed control by optimizing intercropping cultivation and the establishing of a system for testing the weed suppression of new varieties resp. pre-breeding lines.  These aims should be achieved in the joint project, carried out at the Julius Kühn...

Plant genomics – a way forward?
Provedor de dados: 21
Autores: Beynon, Jim.
This report was presented at the UK Organic Research 2002 Conference. Diseases of plants cause significant losses in crop yield and quality. Plants contain a battery of genes whose role is to prevent pathogens invading. Their effective use in crop plants is very important in crop production and especially in chemical free cropping systems. Such genes are introduced into crop varieties by plant breeding. The new science of genomics may enable scientists to recognise all the resistance genes present in a plant. This will eventually allow plant breeders to more precisely and rapidly select useful resistant plants in their breeding programmes. Furthermore, genomics could enable effective deployment of these genes in cropping systems, so providing more durable...

Global change is increasingly affecting agricultural production and threatening food security. Organic and low-input farming systems are less demanding in fossil energy and might thus contribute to moderating global carbon missions. Moreover, under increased uncertainty and variability in environmental conditions, these systems offer solutions for buffering against climatic extremes, disease epidemics, changing nutrient availability, and other stresses that will add to already heterogeneous environmental conditions.  2010 has been designated the Biodiversity Target year by Parties to the Convention on Biological Diversity. Yet, it is clear that biological diversity in agroecosystems, measured as the number and abundance of species as well as genetic...

Spore contamination of Tilletia tritici in seed lots as affected by field disease incidence
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
Seed lots normally become contaminated by spores of the seed borne common bunt (Tilletia tritici) during harvest of fields with infected plants. To demonstrate the relation between the number of infected plants in the field and the resulting number of spores in the harvested seed lot, a fixed number of infected tillers were placed in uncontaminated wheat fields. Two field experiments show   that the number of spores in the seed lot is proportional to the number of infected plants in the field. Only 3% of the spores from the infected plants in the field end up in  the seed lot after harvest with a combine harvester. However, only few spores in a seed lot is enough to establish infection in the next year field, and with a threshold of 10 spores/g seed which...

The UK body that oversees standards in organic farming, the United Kingdom Register of Organic Food Standards (UKROFS), has ruled that genetically modified (GM) crops have no role to play in organic farming systems. They, therefore, have concerns about the possibility and consequences of the mixing of GM crops with organic crops.      The two main sources of mixing are through pollen and seed. Pollen from GM...

Marker assisted breeding and mass selection of wheat composite cross populations
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Lazzaro, Mariaterresa; Backes, Gunter; Rasmussen, Søren Kjærgaard.
Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time.

Composition of variety mixtures in barley and wheat
Provedor de dados: 21
Autores: Østergård, H.
Breeding within the last 50 years has focused on developing genetic uniform crops/varieties for farmers to be able to produce homogeneous products to be sold. Therefore, especially for selfing crops like wheat and barley where nearly all plants in a field are genetical identical, specific tools have to be applied to ensure genetic diversity. Among these tools is the use of variety mixtures. Principles for composing variety mixtures are to a large extent based on disease resistance characteristics and this is insufficient to predict the performance of the mixtures. Biological principles for interactions between varieties will be of relevance not only to organic farming but also to conventional agriculture where variety mixtures have been used for many years...

Adding Value to Organic Milk Production Systems: opportunities for marketing meat and milk from dual purpose breeds
Provedor de dados: 21
Autores: van Diepen, Pauline.
There is growing demand for and supply of organic milk. This results in more organic steers being produced. Many organic steer calves are sold to non-organic producers or are destroyed at birth. This is a serious issue for the organic dairy sector.  This report also provides an overview of the current situation of the meat from the organic dairy sector, identifies opportunities for improving the marketing of organic dairy steer calves and provides a special focus on the use of dual-purpose breeds.  Dual-purpose breeds were more often used in the past. Some organic dairy producers have returned to using dual-purpose breeds such as the MRI (Maas Rijn Ijssel) and the Shorthorn.  Stakeholder interviews showed that the high milk price makes the dairy farmers...

Fortführung der Sortenevaluierung auf Flug- und Hartbrandanfälligkeit der Wintergerste sowie Prüfung flug- und hartbrandresistenter Sorten auf Anbaueignung bei ökologischer Bewirtschaftung
Provedor de dados: 21
Autores: Lorenz, Norbert; Klause, Stefan; Spieß, Hartmut.
Im ökologischen Getreideanbau soll ausschließlich ökologisch erzeugtes Saatgut eingesetzt werden (EU-Verordnung 1452/2003). Ohne die konventionell übliche Beizung des Saatgutes erhöht sich das Risiko der Verbreitung saatgutbürtiger Krankheiten. Bei der Wintergerste gilt dies für den zunächst als Spore außen am Korn anhaftenden Gerstenhartbrand (Ustilago hordei ) und insbesondere für den sich bereits im Samenkorn befindlichen Gerstenflugbrand (U. nuda). Einen Ausweg bietet der Anbau von resistenten oder toleranten Sorten.  Um zu Empfehlungen geeigneter Sorten für die ökologische Bewirtschaftung zu kommen, wurden im Rahmen des Bundesprogramms Ökologischer Landbau Sortenversuche mit aufgrund guter Resistenzeigenschaften gegen Flugbrand ausgewählten mehr (mz)...

The identification and production of varieties that increase the value of oats as a profitable component of organic production
Provedor de dados: 21
Autores: Clarke, S M; Haigh, Z; Hinchsliffe, K E; Jones, H E; Wolfe, M S.
Two experiments, one comprising husked, and the other naked, oats were established at Wakelyns Agroforestry, Suffolk in October 2004 to determine traits and varieties of oats suited to organic systems, and whether growing variety mixtures conferred any advantage. Unselected F2 breeding lines were also included for selection. Husked varieties had relatively higher yields; this may have been partly the result of poor establishment in the naked varieties. Variety height was found to be an important characteristic; tall oat varieties out-yielded the dwarfs. Two of the three variety mixtures containing the naked oat variety Expression yielded 8 and 9 % higher than the average of the component varieties. The data will be verified in the second year of replicated...

Rhizosphere microbiome and disease resistance - Project presentation
Provedor de dados: 21
Autores: Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Messmer, Monika.
Disease resistance is not a mere plant but a system trait involving the complex plant-associated microbial community (Berendsen et al. 2012). As with pathogens, past research often focussed on single, culturable symbiotic microbes. More recently, microbial shifts on the community level have been linked to disease resistance. However, simplistic statements such as “high microbial diversity equals healthier plants” were not confirmed in most recent microbiome analyses (Hartmann et al. 2014, Yu et al. 2012). Plants have the ability to influence the microbial structure in the rhizosphere. Besides soil type, it has been demonstrated that not only different plant species, but also different genotypes within the same species can modify the rhizosphere microbiome...

Organic breeding should select for plant genotypes able to efficiently exploit indigenous Probiotic Rhizobacteria
Provedor de dados: 21
Autores: Bosco, M.; Baruffa, E.; Picard, C.
In order to rapidly achieve crop varieties adapted to organic crop production systems, it is of crucial importance to know plant genotype potential for positive interactions with soil indigenous microflora. In this frame, European research efforts are now considering beneficial non-symbiotic (probiotic) rhizobacteria as an essential factor for sustainable plant breeding. Published findings are beginning to elucidate how probiotic rhizobacteria contribute to plant nutrient assimilation and disease resistance. Future efforts for crop breeding in organic agriculture should take into the right account the capacity of plants to efficiently exploit indigenous probiotic rhizobacteria in low-input cultural conditions.

Autores: Grohmann, Markus; Winckler, Christoph; Perler, Erika; Isensee, Anne; Christ, Benedikt; Amsler, Zivile; Werne, Steffen; Maurer, Veronika; Heckendorn, Felix.
The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined.

EFFECT OF DIFFERENT ECOLOGICAL ENVIRONMENTS ON ORGANIC CULTIVATED SOYBEAN (Glycine max (L.) Merril.)
Provedor de dados: 21
Autores: Borbélyné Hunyadi, Éva.
In recent years different protein sources have gained importance. Crop cultivation plays an important role in meeting the demand for many of these. In order to improve the quantity and the quality of yields; we must acquire a complex ecological attitude and exercise a more rational use of natural resources. To succeed requires favourable material, technical and social circumstances. The exploitation of genetic capability – as a form of renewable resource – is a fundamental method for increasing yields. To do this we must harmonize the biological needs of the given variety, its ecological attributes, with the circumstances of its cultivation.   Today, the soybean is one of the most important plant sources of protein and vegetable fats (Bódis and...

Framtagning av lokalanpassade stråsädessorter för ekologisk odling genom deltagande forskning
Provedor de dados: 21
Hypotesen är att lokalanpassade sorter kan ha bättre förutsättningar än konventionella sorter när det gäller ogräskonkurrens och motståndskraft mot sjukdomar. I projektet arbetar forskare tillsammans med ekologiska odlare för att välja ut de sorter som passar bäst för en region. Sorterna ska förutom goda odlingsegenskaper också ha bra bakningsförmåga och goda egenskaper när det gäller kvalitet och smak. Fram till tidigt 1960-tal hade växt- förädlingen ungefär samma förutsättningar som ekologisk odling har i dag, dvs. liten insats av gödselmedel och inga växtskyddsmedel. Man screenar detta tidiga sortmaterial, men jämför också med moderna sorter med attraktiva egenskaper.

Flåttbåren sykdom og velferd hos sau
Provedor de dados: 21
Autores: Grøva, Lise; Olesen, Ingrid; Stuen, Snorre; Steinshamn, Håvard.
De største utfordringene for velferden på sau i beiteperioden er sjodogg, fluelarver, alveld og rovdyr (Norges Forskningsråd 2005, Norsk sau og geitavlslag 2001). Økte transportavstander og transporttid samt negativ økonomisk utvikling i saueholdet og en dreining mot mer ekstensive driftsformer gir også grunn til bekymring for velferden til sauen i norsk sauehold.    I økologisk landbruk er et høyt nivå på dyrevelferd og god dyrehelse eksplisitte mål (Debio 2003). Muligheten til å utøve naturlig atferd er et viktig prinsipp, og beitedrift er derfor et viktig aspekt i økologisk landbruk. Utfordringene i både økologisk og konvensjonelt landbruk er ofte sammenfallende, men i økologisk landbruk legger en spesielt stor vekt på årsaksorientert problemløsing og...

Various ways for successful Cultivar introduction in the market
Provedor de dados: 21
Autores: Nuijten, E.; Zeelenberg, Arend; Janmaat, Leen; Lammerts van Bueren, E.T.
Organic production requires novel, robust cultivars especially for crops such as apple, grape, tomato and potato which are very disease susceptible and are often protected by copper compounds. The European project CO-FREE aims to develop innovative methods, tools and concepts for the replacement of copper to reduce the use of copper in organic farming systems. One key strategy is the introduction of resistant cultivars. However, previous studies have shown that the introduction of novel cultivars often meets substantial obstacles as retailers’ and/or consumers’ awareness has to be generated in order to open the market. Resistance is an important issue for farmers but not immediately appealing for consumers as they are hardly aware of the fact that current...

Due to the decreased demand for grain legumes, breeding and research efforts in this area have declined in Europe. In an effort to counteract this development, the European project COBRA was launched. COBRA aimed to support and develop  organic plant breeding and seed production with a focus on increasing the use and potential of plant material with High genetic Diversity (Hi-D) in cereals (wheat and barley) and grain legumes (pea and faba bean) through coordinating, linking and expanding existing breeding and research. The aim of the trial at hand was to pre-test new varieties and breeding genotypes of faba bean and pea in pure stand and in  mixture with cereals under organic growing conditions in Luxembourg.

Autores: Oehen, Bernadette; De Gregorio, Julia; Petrusan, Janos; Moschitz, Heidrun.
Common wheat (Triticum aestivum) and barley (Hordeum vulgare) are the most important cereals grown in Europe (in ha). Both crops are suitable for large-scale crop production Other crop species like spelt (T. spelta), rye (Secale cereale), oats (Avena sativa) emmer (T. dicoccum) and einkorn (T. monococcum)are not relevant to food or feed production anymore.   In comparison to conventional common wheat, minor cereals typically grow well in poor soils or under low input conditions, and there are hints that the nutritional quality is high.   However, MC have been hardly developed as commercial crop varieties, with virtually no major investment in exploiting genetic diversity, breeding programmes, and optimising of agronomic and food industry processes....

Wheat populations: parental performance and stability in organic and non-organic environments
Provedor de dados: 21
Autores: Jones, H; Boyd, H. E.; Clarke, S; Haigh, Z. E. L; Wolfe, M.
Twenty winter wheat varieties used as parents in a half diallel crossing programme for the production of wheat populations were grown in field trials at two organic and two non-organic sites over three years in England. Yields of the varieties between the two non-organic sites were highly correlated, but less so between the two organic sites and between the non-organic and organic sites. At the non-organic sites, most of the variation in yield (60%) was due to varietal differences, whereas, at the organic sites, it was due largely to the effects of environment (79%), and genotypic variation only accounted for 9%. More detailed analysis, using AMMI (Additive Main effects and Multiplicative Interaction), allowed stricter comparisons among individual...

Provedor de dados: 21
Autores: Ivemeyer, Silvia; Brinkmann, Jan; March, Solveig; Simantke, Christel; Winckler, Christoph; Knierim, Ute.
Organic milk production varies due to topographical and structural farm conditions, but very little information is available about this variation in Germany.  The aim of this study was to identify typical major farm types (MFTs) of German organic dairy farms and to describe their farm, herd, and management characteristics.  Based on data from 204 organic dairy farms from previous studies with representative samples, fourMFTs were identified by cluster analysis. Cluster-criteria were herd size, milk yield, region, and housing system. Identified MFTs were (A) medium-scale herds with low-tomedium milk yield, (B) small-scale herds with low milk yield, (C) large scale herds with high milk yield, and (D) medium-scale herds in Southern Germany with medium milk...

Muligheder for at fremme en sundere fedtsyresammensætning via avlsarbejde
Provedor de dados: 21
Autores: Poulsen, Nina Aagaard.
Økologisk mælk har en sundere fedtsyreprofil end konventionel mælk. Denne forskel kan til dels forklares ud fra forskelle i fodring og til dels ud fra genetiske forskelle. Hypotesen er derfor, at det er muligt at fremme en sundere fedtsyresammensætning via avlsarbejde. I præsentationen beskrives baggrunden for hypotesen og en metode til at teste hypotesen.

Entwicklung eines Zuchtgarten-Befallsmanagements für die Züchtung flugbrandresistenter Sommergersten unter natürlichen Befallsbedingungen
Provedor de dados: 21
Für den ökologischen Landbau sind derzeit keine praktikablen Saatgutbehandlungsmethoden zur Reduzierung des Flugbrandbefalls unter die für die Basis- oder Z-Saatguterzeugung vorgesehene Schwelle in Sicht. Resistenzzüchtung ist momentan die einzige Möglichkeit. Jedoch schrecken viele Züchter bezüglich der Züchtung auf Flugbrandresistenz zurück, aus Angst vor einer unkontrollierten Ausbreitung der Krankheit im Zuchtgarten. Da es im Zuchtgarten auf einzelne Ährennachkommenschaften ankommt, kann ein zu hohes Befallsniveau zum Verlust ganzer Zuchtlinien führen, auch wenn diese aufgrund anderer Eigenschaften für die weitere Züchtung besonders erhaltenswert wären. Ein zu niedriges Befallsniveau erfordert umfangreiche und aufwendige Nachprüfungen mittels...

Autores: Paczkowski, A.; Isselstein, J.; Hartmann, S.
Aufgrund des hohen Proteingehalts und günstigen Aminosäurenprofils der Blätter von Luzerne und Rotklee wird der Blattmasse immer mehr Bedeutung zugeschrieben. Jedoch liefern bisher vorhandene Ergebnisse nicht ausreichend Informationen in Bezug auf den zu erwarteten Blattertrag unter Berücksichtigung von Sorte und Standortunterschieden wie z.B. Klima oder Bodenart. Um den Einfluss des Standortes auf den Blattertrag ausgewählter Luzerne- und Rotkleesorten aufzuklären, wurde im Sommer 2017 auf vier Luzerne- und fünf Rotkleestandorten in Hessen, Thüringen und Bayern ein langjähriges Experiment gestartet. Die Ergebnisse der ersten Beprobung zeigen, dass sowohl  die diploiden als auch die tetraploiden Rotkleesorten hohe Blattmasseerträge liefern. An Standorten...

Provedor de dados: 21
Autores: Schmehe, Ben; Becher, Thorben; Spieß, Hartmut.
In 2005 an organic oat (Avena sativa L.) breeding programme was initiated by the on farm breeding and research institute at Dottenfelderhof, Hessen, Germany, with the purpose of releasing oat varieties suitable for organic agriculture. From the very beginning it was one goal to develop varieties resistant to loose smut of oat (Ustilago avenae), which can be a severe problem for the certification of seeds. Therefore registered varieties as well as gene bank accessions were used for crosses and evaluated for resistance to loose smut over the years. In this paper the selection process is being described and the resistant level of the present filial generations in 2012 is shown. Additionally the results of the evaluation of registered varieties from 2010-12...

Rotkleegras im Organischen Landbau: Einfluß von Arten- und Sortenwahl auf Ertrag und Futterqualität
Provedor de dados: 21
Autores: Haas, Guido; Schlonski, Anja.
Im Organischen Landbau ist die Stickstoffixierungsleistung des Rotklees eine wesentliche Zielgröße beim Anbau von Rotkleegrasgemengen. Eine aus Gründen der Futterqualität vorgegebene Zielgröße von 50% - 70% Grasanteil steht dem entgegen. Es sind die Leistung des Rotklees nicht beeinträchtigende Grasanteile anzustreben. Den optimalen Grasanteil gilt es in Abhängigkeit von der Grasart für die Anbauziele im Organischen Landbau zu definieren. Er dürfte bei etwa 20% - 30% liegen.   Im Gemenge mit Rotklee kommt dem Gras zum Zwecke der Verfütterung und Silierung eine die Qualität ausgleichende bzw. aufwertende Funktion zu. Dies beinhaltet u.a. die Absenkung der hohen Pufferkapazität Rotklees und die Anhebung der geringen Gehalte an wasserlöslichen...

Autores: Hörning, Prof. Bernhard; Feige, Martina; Dollinger, Julia.
This study aims to compare conventional and organic farms with beef-suckler herds. Addresses were collected mainly by contacting breeding associations and farmers' magazines. 216 questionnaires were evaluated (34.1% of them organic). Beef-suckler production in Germany is an extensive production system (small farms, small herd sizes, high percentage of grassland, low soil points, etc.). 39% of farms had to fulfil special regulations for extensive grassland production and 43% carried out landscape conservation measures. Farmers specialize in beef-suckler production. 60% of them are part-time farmers. Beef production amounts to two thirds of their agricultural income. Most farmers keep only beef cattle on the farms. Other farm animals are kept in small stock...

Provedor de dados: 21
Autores: Garmo, Randi T.; Ropstad, E.; Havrevoll, Ø.; Thuen, E.; Steinshamn, H.; Waldmann, W.; Reksen, O.
Relationships among commencement of luteal activity (C-LA), milk yield, and energy balance (EB) were investigated in 3 selection lines of Norwegian Red cows at the Norwegian University of Life Sciences from 1994 through 2001. The cows were selected for low genetic merit for milk yield (LMP), high genetic merit for milk yield (HMP), and a combination of high indices for milk yield and fertility (HI). Breeding values for fertility were based on 56-d nonreturn rate. The material included 268 lactations from 147 cows. Milk samples for progesterone analysis were drawn 3 times weekly from 1994 through 1998, and 2 times weekly from 1999 to 2001. Commencement of luteal activity was defined as the first 2 consecutive measurements of progesterone concentration &gt;3...

Reduction of spore spread of common bunt (Tilletia tritici) via combining equipment
Provedor de dados: 21
Autores: Kristensen, Lars; Borgen, Anders.
The disease common bunt (Tilletia tritici syn. T.caries) has become a more frequent problem in Europe during the last 15 year. In organic farming, common bunt causes serious problems for seed producers, and many seed lots are discarded due to contamination with Tilletia tritici. Due to the biology of Tilletia tritici, with spores loosely attached to the surface of the grain, there is a risk that spores can be disseminated via grain handling equipment, including combine harvesters. Preventive efforts should focus on the role of grain handling equipment, and how the fungus life cycle can be broken. We have investigated the dissemination of spores via the combiner after harvesting infected fields. We conducted six trials over three years, counting the number...

Development of genetic models to breed for mixed cropping systems
Provedor de dados: 21
Autores: Haug, Benedikt; Messmer, Monika; Forst, Emma; Mary-Huard, Tristan; Enjalbert, Jérôme; Goldringer, Isabelle; Hohmann, Pierre.
Introduction  Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have...

COBRA: Coordinating Organic Plant Breeding Activities for Diversity
Provedor de dados: 21
Organic plant production is currently challenged by several pressure factors. Along with perennial problems such as weed control, climate change is threatening to affect crop production through increasing weather variability. Plant breeding is a crucial factor in creating organic crop production systems that can better cope with such interacting stresses and producers need crop varieties with (a) good resistance against pests and diseases, esp. seed borne diseases; (b) the ability to react to environmental, esp. climatic variability; and (c) high competitiveness against weeds. COBRA aims to support and develop organic plant breeding and seed production with a focus on increasing the use and potential of plant material with High genetic Diversity (Hi-D) in...

Kupferfreier Anbau von Biokartoffeln
Provedor de dados: 21
Autores: Gelencsér, Tobias; Dierauer, Hansueli.
Die getesteten Sorten schnitten im 2018 alle recht gut ab, vor allem auch wegen der ausbleibenden Regenfälle und dem geringen Krautfäule-Druck. Dadurch konnten die Sorten leider erneut nicht auf das Hauptkriterium Krautfäulewiderstandsfähigkeit hin geprüft werden. Es wird deshalb empfohlen, die Sorten im Folgejahr erneut zu testen.  Die agronomischen Eigenschaften der Sorten waren zufriedenstellend, mit den Stärken und Schwächen der einzelnen Sorten sollte man leben können. Was jedoch zum Ausschlusskriterium führen könnte, ist das Aussehen und der Geschmack der Knolle. Gerade Acoustic, die recht stabil zu sein scheint, hat unvorteilhafte Knollenform und -farbe. Allians wird hingegen mit der regelmässigen, länglichen Form und dem tiefgelben Fleisch eher den...

Resistenzzüchtung für den Ökologischen Landbau bei Getreide
Provedor de dados: 21
Autores: Miedaner, T.; Fischer, K.; Merditaj, V.
Fazit  Auch im Ökologischen Landbau gibt es Forschungsbedarf für Resistenzzüchtung, die Schwerpunkte sind aber teilweise andere als im konventionellen Bereich.   Bei Ährenfusariosen kann der Ökologische Landbau die vielfältigen Bestrebungen der konventionellen Züchter nutzen, in dem er die Resistenz bei der Sortenwahl berücksichtigt. Bereits mittelanfällige Sorten könnten hier einen ausreichenden Schutz bieten.  Bei Mutterkorn ist dringender Handlungsbedarf bei Roggen geboten, da hier mit Kulturmaßnahmen wenig Fortschritte zu erzielen sind. Die genetischen Unterschiede lassen gute Selektionsmöglichkeiten erwarten. Bei Triticale scheint aufgrund der bisherigen Ergebnisse wegen des geringen Befalls keine Züchtung erforderlich zu sein.   Anders sieht es bei...

Neues Konzept für die ökologische Tomatenzüchtung
Provedor de dados: 21
Trotz steigender Nachfrage stagniert in Deutschland der ökologische Anbau von Tomaten. Ein zunehmendes Problem im geschützten Anbau ist die Samtfleckenkrankheit, verursacht durch den Pilz Passalora fulva (syn. Cladosporium fulvum). Der saisonale, kostengünstige Anbau unter Folie ist dabei besonders betroffen. Die als resistent ausgewiesenen Sorten geben in den traditionellen Anbaugebieten wie am Bodensee mit einer jährlich hohen Befallsgefahr keinen ausreichenden Schutz mehr. Ziel des Projektes ist es, ökologisch angepasste Sorten mit stabiler Resistenz und einem guten Geschmack zu entwickeln. Zum einen soll eine neue, auf das System angepasste Züchtungsstrategie (F4 Kreuzungsnachkommen) erprobt (1) und zum anderen durch reine Kreuzungszüchtung neue...

Cocoa Yield Development in Alto Beni, Bolivia: Influence of Sites, Varieties and Years
Provedor de dados: 21
Autores: Schneider, Monika; Perez, Eucebio; Alcon, Freddy; Choque, Romero; Trujillo, German; Andres, Christian.
One of the most essential limiting factors of cocoa (Theobroma cacao L.) productivity worldwide is pests and diseases. Each of the major production regions has its specific pests and diseases. Reported yield losses range from minor to almost 100 per cent.  In Alto Beni, located in the Amazonian watershed of the department La Paz, Bolivia, the Research Institute of Organic Agriculture (FiBL) and its local partners are addressing several problems of cocoa producers using a participatory technology development approach.  Problems were identified in a participatory way and are, in order of priority, i) to reduce the incidence of pests and diseases, mainly the cocoa mirid (Monalonion dissimulatum) and Frosty Pod Rot (Moniliophthora roreri); ii) to evaluate the...

Züchterische Verbesserung der sensorischen Qualität der  Pastinake (Pastinaca sativa L.) im Praxisbetrieb
Provedor de dados: 21
Autores: Horneburg, Bernd; Bauer, Dieter; Bufler, Gebhard.
Parsnip (Pastinaca sativa L.) is one of the few cultivated plants domesticated in  Europe. The crop is underutilised and the number of available varieties is small in  Central Europe. On-farm management of genetic resources can be an important  means to increase infraspecific diversity, and to improve the quality of crops. In the  present experiment quality-improvement by progeny selection on-farm was  investigated. In a first step parsnips were selected for organoleptic quality by a  technique that allows to harvest seeds from the plant tested. In a second step,  progenies of positive- and negative-selected plants were compared with the original  population. The experiment was carried out with the varieties Aromata (2006) and  White King (2008) in...

Situation Analysis and Strategy for Replacing Cell Fusion Cultivars in Organic Systems
Provedor de dados: 21
The report was prepared by the members of the IFOAM-Organics International Working Group on Replacing Cell Fusion Cultivars: Kirsten Arp, Diane Bowen (Chair), Bernd Horneburg, Andre Leu, Rodel Maghirang, John Navazio, Gebhard Rossmanith, Michael Sligh, Yiching Song, and with additional support from Monika Messmer.  History of the initiative  In 2002 the first IFOAM draft standards were set for organic plant breeding. They stated that only breeding techniques on plant level are compatible for organic principles.  This implies that from the process point of view, plant breeding techniques that operate on cell tissue or directly at DNA level violate the integrity of life. Respecting the concept of integrity of life also means that organic agriculture aims to...

Influence of the Fast Spread of Bt Cotton on Organic Cotton  Production: Examples from India and Burkina Faso
Provedor de dados: 21
Autores: Klaiss, Matthias; Messmer, Monika; Forster, Dionys; Verma, Rajeev; Baruah, Rajeev; Rawal, Vivek; Mandloi, Lokendra S.; Shrivas, Yogendra.
COTTON is grown in more than 120 countries by over 20 million cotton producers on 35 million ha in 2012 (Truscott, 2010, www.fas.usda.gov). In 2011, around 27 million tons of cotton were produced, mostly by smallholder producers in 'developing' countries which cultivate cotton as a cash crop on their own land averaging under 2 ha in size, or as contracted workers for bigger land owners. Cotton is usually grown as a monoculture. In industrialised countries, the level of mechanisation is high, thus cotton production does not provide a lot of work in rural communities. In contrast, in developing countries, the cultivation and harvest is mostly done by hand labour and thus provides a lot of work for the rural population. Cotton, particularly as a monoculture,...

Assessing varietal resistances to control common wheat bunt under organic cereal production and soft wheat, in particular
Provedor de dados: 21
Autores: FONTAINE, L.; du CHEYRON, P.; MORAND, P.; SKIKERS, S.
Common wheat bunt (caused by the fungus Tilletia caries or Tilletia foetida) is a disease whose incidence is clearly on the rise in organic farming, jeopardising the balance of the French organic cereal sector. Control methods adapted to organic farming must be found, especially since we know that no seed treatment is 100% effective. The use of varietal resistance appears particularly promising for limiting the spread of the disease. Since 2000, an experiment whose purpose is to assess the resistance of soft wheat varieties to Tilletia caries is conducted each year by the French plant institute, ARVALIS. These experiments make it possible to identify the existence of a wide behavioural variability with respect to this pathogen among the different varieties...

AN ALTERNATIVE APPROACH TO PLANT HEALTH: THE PROCEDURAL CONCEPT APPLIED TO COMMON BEAN SEED SYSTEMS
Provedor de dados: 21
Autores: Klaedtke, Stephanie; Stassart, Pierre; Chable, Véronique.
Pathogen-free seed is one strategy to protect plants and prevent the introduction and spread of dangerous pests.   While this strategy reduces damage to crops and delays the global spread of pathogens, it may also be regarded as an overly reductionist approach to plant health disfavoring the resilience of cropping systems. Rather than defining plant health as an objective entity, a procedural concept consisting of a set of rules for debate in order to incorporate different viewpoints on the continua between naturalist and normativist approaches, negative and positive definitions, reductionism and holism and functionality and resilience has been proposed. In the ongoing research project presented here, the questions suggested are applied to the case of...

Autores: Jacob, Irene; Hartmann, Stephan; Schubiger, Franz Xaver; Struck, Christine.
Die Pilzkrankheit Anthracnose an Rotklee scheint in Deutschland an Bedeutung zu gewinnen. Zur Identifizierung widerstandsfähiger Rotkleesorten wurde ein Resistenztest im Gewächshaus durchgeführt. Auch andere Futterleguminosen wurden erstmals in diesen Test integriert.  Die getesteten Rotkleesorten differenzieren deutlich hinsichtlich ihrer Anfälligkeit. Die Überlebensrate der Pflanzen schwankte zwischen 29 und 81 %.  Unter den alternativen Futterpflanzenarten zeigten sich die getesteten Sorten von Weißklee, Hornklee und Esparsette als resistent, wohingegen die geprüfte Gelbkleesorte anfällig war. Bei Luzerne und Inkarnatklee traten Sortenunterschiede auf.  Diese Ergebnisse wurden im Rahmen des vom BÖLN finanzierten Forschungsvorhabens FKZ 06OE161 ermittelt.

I afhandlingen beskrives principperne for økologisk plantebeskyttelse og der argumenteres for, at en plantesygdom som stinkbrand primært bør forebygges frem for at blive bekæmpet i et økologisk dyrkningssystem. Stinkbrandens biologi analyseres med henblik på at finde mulige forebyggende dyrkningsmetoder. Endvidere undersøges mulige bekæmpelsesmetoder, som er tilpasset økologisk jordbrug. Det konkluderes, at der findes forebyggende metoder, og at det er sandsynligt, at en systematisk udnyttelse af disse vil kunne forhindre hovedparten af problemerne med sygdommen. Det konkluderes endvidere, at der er muligheder for bekæmpelse i økologisk jordbrug, som kan bruges som sikkerhedsnet under dyrkningssystemet.     I afhandlingen gengives 6 eksperimentelle...

Weizen (Triticum aestivum) ist eine der bedeutendsten Kulturpflanzen für die menschliche Ernährung. Die Notwendigkeit sowohl unter veränderten Klimabedingungen mit häufiger auftretenden abiotischen und biotischen Stresssituationen als auch auf Grenzstandorten langfristig stabile Erträge zu erzielen, führt im konventionellen und insbesondere im ökologischen Landbau zu einem Bedarf an Weizengenotypen mit verbesserter abiotischer und biotischer Stresstoleranz.

Efficient Multi-location Testing of Scab Resistant Cultivars for Organic Apple Production in Switzerland
Provedor de dados: 21
Autores: Weibel, Franco; Schmid, Andi; Häseli, Andreas.
The market and production of organic apples is growing worldwide. Most of the production occurs on freshly converted orchards with cultivars very sensitive to apple scab (Venturia inaequalis) that in humid conditions need an intensive plant protection program. For the future development of organic fruit growing towards a credibly sustainable production it is necessary to replace these cultivars with scab resistant or tolerant cultivars. Cultivar testing under organic growing conditions is therefore an important task. We describe our testing concept that consists of precision trials where cultivars are tested with an without aphid control and with and without crop load regulation. In parallel, we carry out on-farm trials with the most promising cultivars on...

Vergleich der Adaptation von Winterweizenpopulationen mit unterschiedlichem Anbauhintergrund
Provedor de dados: 21
Autores: Weedon, Odette; Haak, Jette; Brumlop, Sarah; Finckh, Maria R.; Heinrich, Sven.
Thirteen winter wheat composite cross populations originating from one population but with differing histories over six years and three reference varieties were compared for yield, disease occurrence, as well as phenotypic diversity. The populations performed similarly and often better than the reference varieties in terms of yield and had lower incidence of disease. The populations are also phenotypically diverse and differ among each other, indicating that they have maintained a high degree of diversity over time and in varying locations, but most likely also diverged from each other.

Guidance Document and Considerations for the Marketing of Biodiverse Food Products
Provedor de dados: 21
Autores: Oehen, Bernadette; Padel, Susanne; Rossi, Adanella.
The prevailing food supply chains are characterised by a highly standardised food offer produced in an impoverished agricultural system. The loss of diversity in food production is not only a loss of crop species and varieties but also a loss of taste, culture and knowledge and adaptability to a changing environment. This booklet is intended to contribute to a transformation of this system by supporting the use of the biological diversity of cultures. It aims at supporting practitioners that want to enhance crop genetic diversity in agricultural systems and increase the link between consumers and producers.   Moreover, the booklet contains a compilation of all the lessons learned from the valorisation of crop genetic diversity during the European research...

Diversified food system: Policy to embedding crop genetic diversity in food value chains
Provedor de dados: 21
Autores: Feher, Judit; Padel, Susanne; Rossi, Adanella; Drexler, Dora; Oehen, Bernadette.
Current food systems and associated agricultural practices have led to a loss of crop diversity. The  widespread adoption of genetically uniform crop varieties  may also increase the vulnerability of production systems  and reduce their adaptability to new environmental challenges. DIVERSIFOOD has explored different approaches  aimed at increasing crop genetic diversity, and as a result, make biodiverse food available to consumers. These approaches have the potential to promote sustainable, locally adapted farming systems, provide autonomy to farmers, support local short and fair supply chains and reconnect farmers and consumers. In order to support these approaches, the following policy changes are needed:  1) The legal status of heterogeneous cultivars...

Wasserökonomie von Luzerne (Medicago sativa L.) im Freilandversuch
Provedor de dados: 21
Autores: Schweinzer, Agnes; Gollner, Gabriele.
Lucerne (Medicago sativa L.) is known for its high water consumption and is one of the most important forage legumes. However lists of varieties are still lacking information about its water use. Therefore this study focused on the evaluation of four varieties` water economy and yield stability by comparing plant water characteristics to plant production characteristics under field conditions. Relative water content (RWC) turned out to be the most proper parameter for analyzing lucerne`s water use regarding a significant variety effect. Nevertheless further research will be indispensable to give explicit cultivar recommendations for breeding purposes.

Autores: Sieber, Karen; Forster, Georg M.; Diekmann, Kerstin; Sprengel, Michael; Kellermann, Adolf; Dehmer, Klaus-J.; Hammann, Thilo.
Die Ansprüche des ökologischen Landbaus an Kartoffelsorten unterscheiden sich zum Teil erheblich von denen des konventionellen Anbaus. Dies ist bedingt durch den alternativen Pflanzenschutz mit mechanischer Unkrautbekämpfung sowie durch eine in der Regel geringere Stickstoffversorgung der Pflanzen. Darum benötigt der ökologische Landbau spezielle Sorten, die neben den vom Verbraucher gewünschten Qualitätsmerkmalen auch eine hohe Widerstandsfähigkeit gegenüber Krankheiten und Schädlingen besitzen, durch schnelle Jugendentwicklung das Unkrautwachstum unterdrücken und eine hohe Nährstoffeffizienz aufweisen.  Um neue Zuchtstämme zu schaffen, in denen die im Biolandbau gewünschten Eigenschaften kombiniert vorliegen, etablierte das seit 2012 im „Bundesprogramm...

Organic Horticultural Seed in Wales - A survey of growers’ experiences of varieties grown from organic seed in 2006
Provedor de dados: 21
Autores: Little, Tony.
The Organic Standards require organic producers to use organic seed. However, a derogation can be obtained from certification bodies to allow the use of non organic seed where appropriate organic material is not available in the UK. An official database of organic seed availability, ‘Organicxseeds’, has been developed and is used as the basis for derogation decisions. However, there is a lack of information and a great deal of uncertainty in the minds of growers, about the performance of many varieties available in organic seed. This means that growers could potentially have to make variety choices on the basis little or no information.     For the last 4 years, Organic Centre Wales, with support from Farming Connect, has coordinated a survey to help...

Fifty-five spring barley varieties from the German official varieties list were tested for their susceptibility to loose smut (Ustilago nuda) and covered smut (Ustilago hordei) under a simulation of natural infection conditions. For loose smut infection cv. ‘Lawina’ with about 5 % infected plants was used as spreader. In the trial with covered smut 1kg of seeds were shaken with 1g of spores to contaminate the surface of barley seeds before sowing. Only ‘Steffi’ stayed absolutely free from loose smut during two infection cycles at two locations. With an average of 12.6 % plants with loose smut ‘Danuta’ was the most susceptible. Most susceptible to covered smut were ‘Tunika’ with 13.2 % and hulless ‘Taiga’ with 15 % infected plants. Thirteen varieties...

Leistung und agronomisches Potenzial von Composite Cross  Winterweizen-Populationen und anderen Phänotypen in einem  Mischanbausystem
Provedor de dados: 21
Autores: Weedon, Odette; Lanvers, J.; Wersebeckmann, V.; Purwien, T.; Heinrich, S.; Finckh, Maria R.
Unpredictable climatic conditions and increasing pressure on non-renewable resources mean that alternative agricultural systems able to cope with increasing biotic and abiotic stresses, as well as external input costs, are needed. Sustainable agricultural systems should be self-regulating, characterized by a high degree of interand intra-specific diversity (Moreau 2010). Evolutionary breeding through the introduction of Composite Cross Populations (CCPs) increases intra-specific diversity, enabling CCPs to adapt to changing environmental conditions. Increasing interspecific diversity, through mixed cropping, also plays an important role in sustainable systems and suitable crops are needed that are able to cope with the increasing interspecific competition...

How to optimize fruit and berry cultivar selection for organic farmers ? A comparison of European approaches.

Most of the currently grown commercial fruit cultivars remain unsuitable to low-input or sustainable organic farming systems. The major reason is that  they have been developed and selected under high input cultivation, and without sufficient attention to susceptibility to pests and diseases. Some of these cultivars are nevertheless marketed as resistant because they carry genetic markers for major resistance genes but these are unfortunately prone to break-down (most of apple resistant cultivars relay only on the Vf). As a result, new fruit cultivars tend to reveal unexpected and often undesirable traits when grown in commercial organic orchards, and thus fail to bring about the much needed expansion in organic production and market availability. However,...

Tolerance to weed harrowing in spring barley genotypes
Provedor de dados: 21
Autores: Hansen, Preben Klarskov.
Controlling weeds in spring cereals grown under organic conditions is mostly done by post emergence weed harrowing, where spring tines of the weed harrow control weeds by uprooting and/or covering small weeds plants with soil. In situations with relatively large weed plants and relatively small crop plants, there are increased risks for crop damages by soil coverage or other mechanical damages of the crop leaves. These damages are increasing with increasing weed control intensity, and are resulting in reduced crop growth immediately after weed harrowing. There are risks that the reduced growth reduces final crop yield too.  However, there is some evidence that there are varietal differences in the tolerance to weed harrowing.    The aim of this study was...

Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection.  Genetically...

Major bottlenecks of cotton production in Nimar valley of central India
Provedor de dados: 21
Autores: Riar, Amritbir; Bhullar, Gurbir S.
Hintergrund und Bedeutung für Coop  Indien ist seit jeher Zeiten ein wichtiger Exporteur von Baumwolle. Im Jahr 2014 / 15 war Indien der größte Baumwollproduzent weltweit, mit 6,5 Millionen Tonnen produzierter Baumwollfaser. Indien ist auch der größte Produzent von "Bio-Baumwolle", mit einem Anteil von fast drei Viertel (74 %) der globalen Bio-Baumwolle Produktion. Weil die Nachfrage nach Biobaumwolle stetig wächst, ist es wichtig, die Produktion von Bio-Baumwolle auf nachhaltige Weise zu sichern – um so mehr, da sich der Anbau von genetisch modifizierter Baumwolle rasch ausbreitet. Dies ist auch für Coop äusserst zentral angesichts dessen, dass Indien der Hauptlieferant ist von Biobaumwolle für die Naturaline-Eigenmarke.  Tatsache ist, dass sich in Indien...

Autores: Boelt, B.; Clausen, D.; Gislum, R.; Hansen, L.M.
Kvælstof er et værdifuldt næringsstof for opnåelse af et højt frøudbytte, men også i relation til justering af væksten i udlægsmarken. Desværre har mange frøavlere begrænset adgang til kvælstof – dels på grund af en kvælstofnorm, som er fastsat under den økonomisk optimale værdi og dels på grund af begrænset adgang til husdyrgødning på økologiske planteavlsbedrifter. I Forskningsprogram frøavl arbejdes med udvikling af en behovsbestemt gødningsstrategi for at opnå en bedre udnyttelse af den til rådighed værende kvælstofmængde. Imidlertid tyder igangværende forsøg på, at kvælstof findes i ’alternative kilder’ såsom frøgræshalm og grøngødningsafgrøder, men kan de udnyttes i frøavlen? En anden supplerende kvælstofkilde er en øget anvendelse af hvidkløver...

Sicherung und Verbesserung der Verfügbarkeit von ökologisch erzeugtem Rotkleesaatgut durch die Entwicklung von Selektionsverfahren gegenüber samen- und bodenbürtigen Pilzkrankheiten zur Züchtung nachhaltig resistenter Sorten
Provedor de dados: 21
Autores: Jacob, Irene; Hartmann, Stehpan.
Rotklee (Trifolium pratense L.) ist ein essentielles Fruchtfolgeglied vor allem im ökologischen Landbau, in dem er als Stickstoffsammler und Proteinlieferant für die Wiederkäuerernährung von besonderer Bedeutung ist. Derzeit scheinen neben abiotischen Ursachen vor allem die Erreger der Anthracnose (auch Südlicher Stängelbrenner genannt, Colletotrichum trifolii) und des Kleekrebses (Sclerotinia trifoliorum) für den Ausfall von Rotkleepflanzen in Deutschland verantwortlich zu sein. Für diese beiden pilzlichen Krankheiten wurden künstliche Inokulationsmethoden geprüft, da eine Selektion auf diese Resistenzen im Freiland durch ein ungleichmäßiges Auftreten der Erreger erschwert wird. Die dargestellte Methode des Anthracnoseresistenztests führt zu...

EFRC Cereal Variety and Mixture Trials 2001 – Preliminary Results
Provedor de dados: 21
Autores: Welsh, James.
Of 7 winter wheats grown at 3 sites in southern England in 2001, the highest yielding was the soft wheat Claire; the breadmaking varieties Hereward, Shamrock and Spark did well. Of the feed wheats, Aardvark outyielded Deben. Of various variety mixtures tried, Aardvark/Claire/Deben was highest yielding. When seed was saved from the 2000 harvest of Hereward/Malacca/Shamrock and grown in 2001, it outyielded the first generation mixture, suggesting that some adaptation had occurred, relative composition changing in response to the local conditions.   Winter oats and triticale were trialled at one site in Berkshire. The triticales Ego and Fidelio performed well, as did the winter oat Kingfisher. The oat mixture Ego/Fidelio/Taurus outyielded the mean of its...

Provedor de dados: 21
Autores: Vogt-Kaute, Werner; Jorek, Bettina; Tilcher, Ralf.
Soil borne diseases cause damage in production of peas on many organic farms. Several varieties and breeding lines from Czech Republic and the United States were compared with German varieties in naturally infected soils. Because of very dry weather conditions a field trial with spring peas did not show diseases. In pot trials some varieties with colored flowers (containing tannine) and some winter peas were included in the trials. Some genotypes showed a tendency to a lower level of infection and to higher plant weights compared to plants grown in soil being treated with heat. But in most cases there were no statistic significances. Nevertheless there is a potential for plant breeding to develop peas varieties with a better tolerance against soil borne...

Lupines will be provided as feeding stuff with high quality for the organic farming. Therefore breeding selection of lupines and a complex quality analysis are necessary. In addition to agronomical characteristics quality parameters are estimated, such as protein content, amino acid composition, fat, fatty acid composition, starch and sugar as well as antinutritive substances (non-starch polysaccharides and alkaloides). On the basis of determined data, NIR/NIT-calibrations are developed as breeding relevant methods. The project serves to both opening up and use of genetic resources and breeding of lupines suitable for ecological cultivation.

Cocoa Yield in Bolivian On-Farm Trials 2010-2013 – Monitoring Outstanding Farmers and Comparing Clones and Sites
Provedor de dados: 21
Autores: Andres, Christian; Perez, Eucebio; Alcon, Freddy; Choque, Romero; Trujillo, German; Milz, Joachim; Schneider, Monika.
Cocoa (Theobroma cacao L.) trees have a lifespan of up to 100 years in their natural environment, the lower strata of tropical alluvial forests. Sustainability of global cocoa production is at stake due to the deterioration of soil fertility, high losses due to pests and diseases (P&amp;D) and old tree stock. Producing cocoa in shaded, low input agroforestry systems offers a potential solution for achieving long-term productivity and sustainability. However, shade-tolerant cocoa clones are needed which are productive and resistant to P&amp;D, as well as meeting the quality standards requested by the industry. In Bolivia, the cocoa mirid (Monalonion dissimulatum) and the novel disease Frosty Pod Rot (“Monilia” Moniliophthora roreri) are among the most...

Breeding for bunt resistance in organic wheat and spelt
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt (Tilletia caries) is one of the most devastating plant diseases, and a particular problem for organic seed production. Organic farming aims at controlling pests and diseases with the use of biodiversity and resistance. However most organic wheat fields today are sown with monocultures of pure line varieties, and resistance to common bunt is rarely used, even this disease  causes severe problems for seed producers and for farm saved seed, as infected seed lots are discarded because of contamination with bunt spores. To improve the system,  organic wheat needs resistance to common bunt that is effective enough to prevent development of the disease over time.  For this reason several initiatives are ongoing to improve bunt resistance in organic...

Whether farming strategies built on continuing input intensification or relying on integrated natural resource management are more sustainable and competitive is at the core of the agricultural development debate. The five-year (2011–16) Sustainable Organic and Low Input Dairying (SOLID) project, funded by the European Commission, involved 25 partners across 10 European countries and was designed to support innovation in European organic and low-input dairy farming. Results show that such systems are very diverse, and need tailor-made farm-specific strategies and related policy measures. This article shows that low-input dairying has country-specific farm characteristics, and is potentially competitive when compared to more intensive dairying systems....

Screening of winter barley varieties (Hordeum vulgare) for resistance against loose smut (Ustilago nuda) and covered smut (Ustilago hordei) in Germany
Provedor de dados: 21
Autores: Lorenz, Norbert; Klause, Stefan; Müller, Karl-Josef; Spieß, Hartmut.
Up to now organic farmers depend greatly on conventionally bred and produced varieties of barley. A turning point was set in 2004 by EU regulation No. 1452/2003 restricting the use of conventionally propagated seed and planting material for organic agriculture. Concerning smut fungi in barley, conventional seed producer's attention was rarely directed to plant resistance due to the possibility of chemical seed treatment (controlling the diseases completely). A main problem for organic seed producers is that organically produced seeds have to fulfil the same regular phytosanitary requirements like conventionally produced seeds. For the production of certified seeds not more than five ears infected with Ustilago hordei (Uh) and/or U. nuda (Un) are allowed on...

Autores: Micheloni, C.; Plakolm, G.
The key questions which will be addressed in this report are:  • Which variety characteristics are important for organic farming and are they different from conventional farmers demand?  • What is an “appropriate“ variety for organic farming?  • Is the actual variety offer available to organic farmers satisfactory? Is it different per crops type and/or per geographic area?  • How should variety trials be conducted in order to supply the information needed by organic operators?  The main answers may be synthesized as follows:  Characteristics of varieties to be used in organic farming are partly different from the ones requested in conventional farming. Main differences are related to yield stability, processing properties and root-system development;  The...

Effects of husked oat varieties, variety mixtures and populations on disease levels, crop cover and their resulting yields
Provedor de dados: 21
Autores: Clarke, Dr S.M.; Jones, Dr. H; Haigh, Miss Z; Boyd, Miss H; Wolfe, Prof. M.S.
Two seasons (2005/06 and 2006/07) of field experiments which aimed to study the suitability of new and established husked oat varieties, variety mixtures and a husked oat population for organic systems were established at two sites in the west and east of the UK. The ground cover and leaf area indices of the varieties had significant effects on final yields in the 2005/06. Mixtures generally yielded similarly to the means of component varieties but the mixtures in 2005/06 and 2006/07 had 25 % and 18 % less disease, respectively, than the average of the component varieties at one site.

The need for increased sustainability of performance in cereal varieties, particularly in organic agriculture (OA), is limited by the lack of varieties adapted to organic conditions. Here, the needs for breeding are reviewed in the context of three major marketing types, global, regional, local, in European OA. Currently, the effort is determined, partly, by the outcomes from trials that compare varieties under OA and CA (conventional agriculture) conditions. The differences are sufficiently large and important to warrant an increase in appropriate breeding. The wide range of environments within OA and between years, underlines the need to try to select for specific adaptation in target environments. The difficulty of doing so can be helped by...

Phytophthora-Resistenz der Kartoffel - Das Wunschmerkmal für den ökologischen Kartoffelbau
Provedor de dados: 21
Autores: Darsow, Ulrich.
Die Resistenzzüchtung bei Kartoffeln gegenüber Phytophthora infestans hat für die Konzeption einer nachhaltigen Landwirtschaft und im Kampf gegen den Hunger weltweit hohe Priorität. Es gibt heute gute Aussichten dafür, durch Resistenzzüchtung etwa 30% des derzeitigen Fungizideinsatzes zu ersetzen. Die Aufnahme der Merkmale relative Kraut- und Braunfäuleresistenz in Programme der Sortenzüchtung erfordert wegen des ungünstigen Erbgangs mehr als eine Verdopplung der Sämlingspopulationen, um geeignete Nachkommen selektieren zu können. Die nötigen Phytophthora-Resistenzprüfungen verlangen hohen Arbeitsaufwand und hohe fachliche Qualifikation. Der züchterische Schwierigkeitsgrad und der zu erbringende, erhebliche zeitliche Vorlauf machen die Bearbeitung dieses...

Yield and quality of wheat cultivars in organic and conventional farming systems - Is there an influence of the breeding history?
Provedor de dados: 21
Autores: Hildermann, Isabell; Fließbach, Andreas; Mäder, Paul.
Organic farmers often use the same wheat cultivars as conventional farmers. Most of these cultivars have been bred under high-input conditions. Organically managed soils frequently do not deliver enough nutrients and fertilizers are limited. Therefore cultivars bred under high-input conditions often cannot perform to the full extent of their high genetic potential. Better nutrient uptake efficiency would be of great value for organic farms and conventional farms, producing under low-input conditions. Studies with winter wheat showed that cultivars, selected directly under organic conditions finally yielded higher under organic conditions than cultivars selected under conventional conditions [1], indicating a successful adaptation to low-input conditions...

Neue Rebsorten müssen klare Vorteile für den Anbauer bringen um akzeptiert zu werden. Eine mehr oder minder stark ausgeprägte Pilzwiderstandsfähigkeit alleine reicht nicht aus, um neue Sorten in den Anbau zu nehmen und am Markt zu etablieren. Umweltleistungen werden vom Verbraucher meist kostenneutral erwartet. Arbeitserleichterung,  Umweltschonung, geringeres Schadrisiko und überzeugende weinbauliche Sorteneigenschaften müssen zusammengehen mit guter Aromaausprägung und akzeptablem Weingeschmack.

Organic breeding should select for plant genotypes able to efficiently exploit indigenous Probiotic Rhizobacteria
Provedor de dados: 21
Autores: Bosco, Prof Marco; Baruffa, Miss Elisa; Picard, Dr Christine.
In order to rapidly achieve crop varieties adapted to organic crop production systems, it is of crucial importance to know plant genotype potential for positive interactions with soil indigenous microflora. In this frame, European research efforts are now considering beneficial non-symbiotic (probiotic) rhizobacteria as an essential factor for sustainable plant breeding. Published findings are beginning to elucidate how probiotic rhizobacteria contribute to plant nutrient assimilation and disease resistance. Future efforts for crop breeding in organic agriculture should take into the right account the capacity of plants to efficiently exploit indigenous probiotic rhizobacteria in low-input cultural conditions.

Provedor de dados: 21
Autores: Weedon, Odette; Haak, Jette; Heinrich, Sven; Finckh, Maria R.
Alternative breeding approaches in organic agriculture have started to address pressing issues such as the lack of appropriate plant varieties particularly suited to cope with higher biotic and abiotic stresses, generally found in low-input and organic production systems. This challenge, coupled with the additional pressure of loss of plant genetic diversity, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity. This High genetic Diversity (Hi-D) approach is relevant to organic agricultural systems for two reasons; firstly the availability of diverse germplasm improves chances of finding germplasm suited for low-input conditions as found in...

Proteinuntersuchungen in Einzelsamen von Lupinen zur züchterischen Erhöhung des Eiweißgehaltes
Provedor de dados: 21
Autores: Jansen, Gisela; Kuhlmann, Josy.
Besides other legumes lupins belong to the local protein crops usuable as feeding stuff in ecologic farming. Therefore an important breeding aim is to provide lupins with high and stable protein content. A non-destructive analysis using near infrared transmittance spectroscopy was developed for determination of protein in single seeds of lupins. Calibration and validation equations were calculated on the basis of 300 single seeds of 3 blue lupins (‘Azuro’, ‘Bolivio’, ‘Boregine’) growing at 3 ecological locations. The estimation of protein content was possible in a range of 15-44% protein with a coefficient of determination (r²) of 0,907 and a standard error of prediction (SEP) of 1,86%. The equation was applied to evaluate the protein content of single...

Provedor de dados: 21
Autores: Konvalina, Petr; Moudry, Jan (Jr.); Capouchova, Ivana; Moudry, Jan.
The technological value of wheat is negatively influenced by organic methods of cultivation. The critical factor is the crude protein content and quality. The aim of this paper is to identify diferences in the quality of eight varieties and two strains of wheat recommended in conventional or organic conditions. Correlation analysis of the qualitative parameters of wheat shows a clear relationship between crude protein content, wet gluten content and Zeleny - sedimentation value. According to the test results, it is appropriate to use the content and quality of protein as selective criteria for the selection of varieties. The Level of baking quality is never reduced below the quality level of the worstquality varieties grown in the same conditions. On the...

High-resolution analysis of a QTL for resistance to Stagonospora nodorum glume blotch in wheat reveals presence of two distinct resistance loci in the target interval
Provedor de dados: 21
Autores: Shatalina, Margarita; Messmer, Monika; Feuillet, Catherine; Mascher, Fabio; Paux, Etienne; Choulet, Frédéric; Wicker, Thomas; Keller, Beat.
Stagonospora nodorum glume blotch (SNG), caused by the necrotrophic fungus Stagonospora nodorum, is one of the economically important diseases of bread wheat (Triticum aestivum L.). Resistance to SNG is known to be quantitative and previous studies of a recombinant inbred line (RIL) population identified a major quantitative trait locus (QTL) for resistance to SNG on the short arm of chromosome 3B. To localize this QTL (QSng.sfr-3BS) with high resolution, we constructed a genetic map for the QTL target region using information from sequenced flow-sorted chromosomes 3B of the two parental cultivars ‘Arina’ and ‘Forno’, the physical map of chromosome 3B of cultivar ‘Chinese Spring’ and BAC-clone sequences. The mapping population of near-isogenic lines (NIL)...

Teelthandleiding Peulvruchten op natuurgronden
Provedor de dados: 21
Autores: Prins, Udo.
Steeds meer akkerbouwers nemen lupines en veldbonen op in hun teeltplan. Dat heeft verschillende redenen. Een stijgende groep consumenten heeft interesse in ‘vergeten groenten’ of wil zijn maaltijd verrijken met hoogwaardig plantaardig eiwit. Voor de bodem zijn dergelijke eiwithoudende gewassen een plus: de teelten leggen stikstof en CO2 vast en verbeteren de structuur en vruchtbaarheid van de bodem. Bij het beheer van natuurgronden staan echter andere doelstellingen voorop. Om op natuurgronden toch succesvol peulvruchten te kunnen telen, is kennis cruciaal. In deze handleiding staan belangrijke do’s and don’ts, verzameld vanuit wetenschappelijk onderzoek en ervaringen vanuit de praktijk in het kader van het project Peulvruchten Voerteelt op Natuurakkers...

Entwicklung und Bewertung von direkten Bekämpfungsstrategien gegen das Auftreten der Möhrenschwärze (Alternaria dauci) beim Anbau von Möhren für die industrielle Verarbeitung
Provedor de dados: 21
Das Forschungsvorhaben hat zum Ziel, die Sicherheit und damit die Wirtschaftlichkeit des Industriemöhrenanbaus zu verbessern. Dies soll einerseits durch die entsprechende Sortenwahl und andererseits durch direkte, den ökologischen Anbaubedingungen entsprechende Pflanzenschutzverfahren (Behandlung des Saatgutes, Ausbringen von Pflanzenstärkungsmitteln und Pflanzenschutzmitteln) geschehen. Die Vermeidung des Anbaus von für Alternaria anfälligen Sorten ist in ökologischen Anbauverfahren als Basis jeder Regulierungsstrategie anzusehen, da diese Vorgehensweise am ehesten den Vorstellungen der ökologischen Landwirtschaft entspricht. Da es im Bereich der Sorten für den Industriemöhrenanbau jedoch bisher nur mehr oder weniger starke Anfälligkeiten für Alternaria...

Seed protein amino acid composition of important local grain legumes Lupinus angustifolius L., Lupinus luteus L., Pisum sativum L. and Vicia faba L.
Provedor de dados: 21
Autores: Schumacher, H.; Paulsen, H. M.; Gau, A. E.; Link, W.; Jürgens, H.-U.; Sass, O.; Dieterich, R.
Grain legumes are regarded as highly valuable protein source for human and animal nutrition. Legume protein quality is mainly limited by the amino acids (AAs) tryptophan and sulphur AA. Organic farming in particular requires high seed protein quality for livestock feeding, as chemically produced AAs must not be feeded. Breeding attempts to increase contents of limiting AA are required. In the present survey, the AA content of 107 cultivars of important European grain legume species (Lupinus angustifolius, Lupinus luteus, Pisum sativum and Vicia faba) was analysed. AA contents were related to the requirements of growing pigs and human nutrition. Feed quality could be enhanced by choice of high quality varieties according to ideal protein concepts. For...

Quality parametres of emmer wheat landraces
Provedor de dados: 21
Autores: Konvalina, Petr; Moudry, Jan (Jr.); Moudry, Jan.
Emmer wheat, Triticum dicoccum SCHUEBL, is an old variety of cereals which has been traditionally grown in aride  areas. Nowdays, it is mainly grown in Italy, Spain, Turkey, Austria and in the Czech republic. This article deals with  a study of quality parametres and selected economic parametres of 6 varieties coming from the genetic resources of emmer wheat. High crude protein content in grain was proved during the trials. Nevertheless, such a characteristic is not suitable for the classical bakery processing (production of leavened products). Low figure of the harvest index is supposed to be the most problematic economic character. However, emmer wheat is a suitable variety for organic farming system. Growing of emmer wheat contributes to an extension of...

Effekte der Saatgutimpfung im ökologischen Soja-Anbau unter  den Umweltbedingungen nördlicher Breiten
Provedor de dados: 21
Autores: Kühling, I.; Hüsing, Bianka; Bome, N.; Trautz, Dieter.
Driven by an increasing demand for GMO-free soya as food or fodder, the production of organic Soybeans increases, also in high latitudes. As a legume crop, soya needs  specific rhizobia bacteria to be supplied by biological nitrogen fixation (BNF). Since most soils lack the soy-specific strains, bacteria material is usually added manually. We set up a field trial with 5 site-years to investigate the benefit of this inoculation procedure in two different environments (humid, Germany/semi-arid, Russia) under organic farming conditions. Overall 5 different varieties were used (at each site 2 individual and 1 joint) to compare inoculation against untreated control. Leaf  chlorophyll as indicator for BNF was determined by a SPAD-502. To make the SPADmeter...

Selecting winter wheat lines from a composite  cross population
Provedor de dados: 21
Autores: Fradgley, Nick; Wolfe, Martin; Howlett, Sally; Creissen, Henry; Girling, Robbie.
The extremely diverse genetic variation in wheat Composite Cross Populations (CCP) represents a valuable source of breeding material.  Such material could be selected as part of a participatory breeding programme with the potential advantage of selecting adaptation targeted for particular environments. For example, selections could be made aimed at producing lines that would thrive under the wide range of management practices conducted as part of organic and low input farming systems.    Ears were selected from a CCP mixed stand under organic field conditions in the UK and Hungary.  Selected lines were multiplied as single ear rows and 1m2 plots.  The best performing five lines from the two selection sites were trialled in Suffolk, UK, in replicated plots...

Entwicklung von Futterrationen für 100%tige Biofütterung von Freilandlegehennen unter besonderer Berücksichtigung von Raps- und Leinkuchen, optimierter Grundfuttereinsatz (Silage) und anderen Eiweißpflanzen
Provedor de dados: 21
Laut EWG-Verordnung 2092/91 ist geplant, den weiteren Einsatz von konventionellen Futtermittelausgangserzeugnissen in der ökologischen Legehennenfütterung zu untersagen. Ziel des Vorhabens ist es, praxistaugliche Futterrationen für Legehennen in ökologischer Haltung zu entwickeln. Dabei wird eine 100%ige Biofütterung mit betriebseigenen Futtermitteln erarbeitet und deren Verträglichkeit bei verschiedenen Legehennenherkünften getestet. Da der Gehalt der Aminosäure Methionin in der ökologischen Legehennenfütterung zumeist ein limitierender Faktor ist, werden verschiedene heimische anbauwürdige Eiweißträger (u.a. Raps, Sommerwicke, blaue Lupine, Leinen, Kürbiskerne) in die Futterrationen integriert. Zudem wird eine Rauhfuttergabe in Form von Silage gesondert...

Enhancing Resilience Through Plant Breeding Requires an Integrated and Interdisciplinary Approach
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.
Breeding in the organic sector is not only a technical activity improving certain desired variety traits but breeding priorities are also determined by the organizational system based on cultural values anchored in specific socio-economic and legal constructions. So, if we want to stimulate breeding for a regionally diverse assortment of varieties of crops that both enhances short-term needed productivity and long-term improved resilience within the frame of the organic principles of health, ecology, fairness and care, we will need to address both the technical and organizational aspects in an integrated and interdisciplinary approach.

Efficacy of non-synthetic seed treatments against anthracnose (Colletotrichum lupini) in white lupin
Provedor de dados: 21
Autores: Haesen, Esther.
White lupin (Lupinus albus) is an interesting crop for use as food, feed, forage or cover crop. However, its cultivation is currently limited because of its high susceptibility to the seed-borne pathogen Colletotrichum lupini, causal agent of lupin anthracnose. Twenty-eight seed treatments were studied here for their efficacy against lupin anthracnose, consisting of 4 hot water, 5 steam, 4 dry heat, 5 electron, 2 plant-based and 2 microbial treatments, as well as 6 controls. Experiments were divided into a germination assay and a pot-based disease assessment experiment. Treatment effects were studied by visual assessments of plants, culture-based incubation of plant tissue and quantitative polymerase chain reaction (qPCR)-based detection of Colletotrichum...

Genotype x management interaction for nutrient use efficiency (NUE) of maize varieties tested under different tillage and fertilization regimes
Provedor de dados: 21
Autores: Messmer, Monika; Uehlinger, Noemi; Berner, Alfred; Scholberg, Johannes; Mäder, Paul.
Most varieties have been selected under high input conditions, including seed treatment, herbicide applications, as well as optimal levels of fast releasing fertilizers. Under organic farming nutrient release is dependent on the temperature and biological activity of the soil and its interaction with the declining residues from previous crops and applied quantity of farmyard manure. As a consequence it is not always possible to match nutrient release with crop demand over time. This effect is even more severe under conservation tillage. To promote conservation tillage in organic farming, it is necessary to identify cultivars that show high nutrient use efficiency (NUE) under these conditions. While there is substantial evidence that breeding for low N...

Dabei zeigten die Sorten/Zuchtlinien Stava, Tambor, Magnifik, SW 51136, Tommi, Tarso, Tataros, Jakobi, Korund, Pegassos, Toronto und Cardos eine Resistenz/Teilresistenz gegenüber Tilletia caries und/oder T. controversa. Ein Einfluß der Sporenherkunft auf das Resistenzverhalten der Sorten schien in einigen Fällen gegeben zu sein.  Parallel wurde ein System zur Frühdiagnose des Befalls mit Hilfe eines immunologischen Nachweises über ELISA standardisiert und an ausgewählten Weizensorten angewandt. Bei Untersuchungen des Vegetationspunktes im Stadium EC 20 konnte an je 45 Einzelpflanzen eine gute...

Yield stability analysis for three winter wheat composite cross populations under organic and conventional management over five years
Provedor de dados: 21
Autores: Weedon, Odette; Brumlop, Sarah; Heinrich, Sven; Finckh, Maria R.
Increasingly uncertain climatic conditions threaten the security and stability of agricultural systems (Østergård et al., 2009; Döring et al., 2011) and a better understanding of genotype x environment (GxE) interactions is needed to shift the agricultural focus from manipulating environments to grow crops to creating crops that fit into the environment (Østergård et al., 2009; Lammerts van Bueren et al., 2012). GxE interactions play a pivotal role in assessing yield stability of crops and the challenge of changing climatic conditions necessitates that new crop cultivars should have broad adaptability, stable agronomic performance over a range of environments and management systems and generally high yields (Akcura et al., 2006). The High genetic Diversity...

Bohne ist nicht gleich Bohne
Provedor de dados: 21
Autores: Strube, Jürgen; Stolz, Peter.
Hydrokultur führt bei Bohnen zu höheren Erträgen, ist aber gleichzeitig qualitätsmindernd. Demeter-Saatgut und konventionelles Saatgut wurden jeweils biologisch-dynamisch und in Hydrokultur angebaut.  Die vorliegenden Ergebnisse legen nahe, dass es auch im Pflanzenbau mehr oder weniger artgemäße Anbaubedingungen gibt. Der biodynamische Anbau in Erde erscheint gegenüber der Hydrokultur als weitaus artgemäßer.   Nicht artgemäßer Pflanzenanbau von weißen Bohnen in Hydrokultur prägt sich im Samen ab und lässt sich mit der hier angewendeten empfindlichen Lumineszens-Anregungs-Spektroskopie physikalisch messen und statistisch signifikant von eher artgemäßem biologisch-dynamischen Anbau in Erde unterscheiden.

Autores: Konvalina, Petr; Moudry, Jan; Suchý, Karel; Capouchova, Ivana; Janovska, Dagmar.
Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties...

Thirteen winter wheat composite cross populations originating from one population but with differing histories over six years and three reference varieties were compared for yield, disease occurrence, as well as phenotypic diversity. The populations performed similarly and often better than the reference varieties in terms of yield and had lower incidence of disease. The populations are also phenotypically diverse and differ among each other, indicating that they have maintained a high degree of diversity over time and in varying locations, but most likely also diverged from each other.

Autores: Peil, A.; Lesemann, S.; Dunemann, F.; Höfer, M.; Flachowsky, H.; Hanke, V.-M.
The Institute of Fruit Breeding has a long tradition in breeding resistant apple cultivars. Systematic resistance breeding started in the 1930 ties in Müncheberg. Material developed in Müncheberg was transferred in the 1970 ties to the Institute for Fruit Research, the antecessor of the Institute of Fruit Breeding. Based on this material, a couple of multiple resistant cultivars were generated. The time schedule for combining biotic and abiotic resistant traits which  demonstrates the long-lasting period necessary for systematic resistance breeding is given. An overview of resistant cultivars of Dresden-Pillnitz and the respective resistant traits is presented. This assortment of cultivars was developed to provide a resistant cultivar for each ripening...

Soil-borne diseases are one of the most important problems in organic and other ‘low input’ soil-based greenhouse production systems. While chemical soil disinfection has been the method of choice in conventional farming systems, soil steaming has been the main strategy for the control of soil borne diseases in organic production. Both methods are extremely expensive and have been increasingly restricted for environmental reasons by government and organic standard setting bodies respectively.  The use of tolerant varieties and of grafting onto resistant rootstocks were evaluated as potential replacements for soil steaming in organic and low input systems and found to be as effective in reducing root disease and increasing root fresh weight, fruit yield and...

A weed suppressive index for spring barley (Hordeum vulgare L.) varieties
Provedor de dados: 21
Autores: Hansen, Preben Klarskov; Willas, Jakob; Kristensen, Kristian.
A screening programme for crop variety competitiveness would ideally be based on only a few, non-destructive measurements of key growth traits. In this study we measured the weed suppressive ability of 79 varieties of spring barley in two ways: 1) directly, by weed coverage assessments under weedy conditions at three Danish locations in 2002-2004, and 2) indirectly, by non-destructive measurements of varietal growth traits under weed-free conditions in 17 other experiments in Denmark in 2001-2003. Based on just four varietal growth traits (reflectance, leaf area index, leaf angle and culm length), we successfully developed a method for indexing the weed suppressive ability of spring barley varieties. The suppressive index ranged from 12% in ‘Lux’ and 55%...

Primary roots and shoots of 13 day old cereal seedlings and quality of seed were  investigated in the frame of the certification process of organic seed produced in  Austria. The germination of seed and the development of seedlings were significantly  affected by Microdochium nivale on wheat, triticale and rye and by Septoria nodorum  on wheat. The number of primary roots was found to be significantly different in wheat  varieties and genotypes but was not influenced by year and region. The number of  primary roots was also positively correlated with the kernel weight of some wheat  varieties.

Autores: Krogmeier, D.
Der ökologische Gesamtzuchtwert (ÖZW) ist ein Gesamtzuchtwert, der der Zuchtzielsetzung in der ökologischen Milchviehhaltung entspricht. Der ÖZW stellt eine „ökologische Reihung“ der aktuellen Besamungsbullen dar und ist ein wichtiges Hilfsmittel für die Zuchtarbeit im ökologisch arbeitenden Milchviehbetrieb.   In den Ausführungen wird der ÖZW in seinen Einzelheiten beschrieben und aufgezeigt, dass ein ökologischer Zuchtwert nicht mit einem ökologisch orientierten Zuchtprogramm gleichzusetzen ist. Ein solches Programm ist aufgrund der geringen Anzahl von Herdbuchkühen in ökologischen Betrieben nicht durchführbar. Eine Beteiligung am bestehenden Zuchtprogramm ist bereits über Paarungsempfehlungen realisiert und sollte weiterentwickelt werden.   Wenn es...

The use of Composite Cross Populations (CCPs) as an alternative breeding approach, has gained significant interest, particularly due to the potential adaptability of evolving populations to specific locations. Three winter wheat (Triticum aestivum L.) CC populations were created in 2001 through collaboration between Elm Farm Research Centre (ORC) and the John Innes Institute in the UK. The populations were created through the inter-crossing of 20 parental varieties, in order to create a high yielding (Y) population; a high baking quality (Q) population and a population consisting of the 9 x 12 (YQ) intercrosses. Since 2005/6 (F5), the populations have been maintained at Kassel University without conscious selection.  The objectives of the study are to...

As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute.

Autores: Haug, Benedikt; Messmer, Monika M.; Enjalbert, Jérôme; Goldringer, Isabelle; Forst, Emma; Mary-Huard, Tristan; Hohmann, Pierre.
Introduction and methods   Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply.   Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in  Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and...

Das agronomische Potential von Winterweizen Evolutionsramschen in verschiedenen Anbausystemen
Provedor de dados: 21
Autores: Weedon, Odette; Finckh, Maria Renate.
Unvorhersehbare und zunehmend unsichere klimatische Bedingungen werden nicht nur abiotische (Hitze, Trockenheit) sondern auch biotische Stressfaktoren (unberechenbares und zunehmendes Auftreten von Pathogenen und Schädlingen) auf die Kulturpflanzen erhöhen. Externe Inputs alleine können diese Probleme nicht entschärfen. Zukünftige landwirtschaftliche Systeme müssen deutlich flexibler auf Stress reagieren können. Vor allem innerhalb ökologischer low-input Anbausysteme hat die Züchtung von Evolutionsramschen, die auf der Herstellung heterogener, evolvierender Composite Cross Populationen (CCPs) basiert, zunehmende Aufmerksamkeit geweckt. Die Vorteile solch genetisch vielfältiger Populationen umfassen u.a. flexiblere Reaktionen auf Stressfaktoren, die...

This study will aim to establish whether crop varieties require dedicated organic trials or whether advice on their performance under organic conditions can be extrapolated from conventional trial data. A number of varieties from different vegetable types will be selected for their expected suitability for production under organic conditions. Selected varieties will be used in trials examining parameters such as speed of emergence and establishment, total and marketable yields, quality attributes, pest resistance and incidence of disease. The establishment of reliable data with these crops will allow additional advice to be provided to organic growers on the most appropriate variety and husbandry techniques to obtain maximum marketable yield of good...

The Breeder’s Eye – Theoretical Aspects of the Breeder’s Decision-Making
Provedor de dados: 21
Autores: Timmermann, Martin.
The report describes an empirical research project which investigated the peculiarity and role of knowledge gained through experience in plant breeding from the breeder’s perspective. In this paper, a theory respecting the breeder’s decision-making process will be presented. The categories of knowledge that are important for the decision-making process will be sketched and three levels of  consciousness elaborated. The integration of all levels of knowledge and consciousness is what in the end determines whether the breeder’s decision-making activities are competent or not. This complexity is defined as intuition in the sense of an invariant present. The empirical findings will be briefly discussed with respect to their importance to organic agricultural...

Autores: Ruess, Franz.
Fireblight (Erwinia amylovora) was detected on rootstocks in several apple orchards in Baden-Württemberg. In Germany the mostly used rootstocks on apple ‘M9’ and ‘M26’ are known to be susceptible to fire blight. Therefore the LVWO Weinsberg participated in the “European Cornell-Geneva rootstocks trial” which is a common experiment of seven research institutes over whole Europe. Six fire blight resistant or tolerant root-stocks from the Geneva® breeding program were tested in comparison to ‘M9’ (Type T337 and Pajam 2). The variety was ‘Golden Delicious’ and the trees were planted in 2001 . An outstanding new rootstock was ‘Geneva® 11’. The tree size was similar to ‘M9’ (above 7% more growth in comparison to ‘T337’). Besides that the influence on the fruit...

Autores: Aguiar, Ananda Virgínia de; Sousa, Valderês Aparecida de; Shimizu, Jarbas Yukio.
The main deterrent to the adoption of new species for operational plantations is the availability of  genetically improved seeds in sufficient amount to supply the  market. Therefore, this study was carried out with the objective to estimate genetic parameters for individual selection as a basis to transform the field trial into a seedling seed orchard. The trial contained forty seven half-sib families from five Mexican provenances, including northern and central Mexico sources. These were planted at Ponta Grossa, Paraná State, Brazil, in arandomized complete block design with nine  replications of five-tree linear plots in a 3 m x 3 m spacing. Height, dbh (diameter at breast height) and stem form were assessed in thirteen-year old tree. Variance...

The flower flies and the unknown diversity of Drosophilidae (Diptera): a biodiversity inventory in the Brazilian fauna
Provedor de dados: 84
Autores: Schmitz,Hermes José; Valente,Vera Lúcia da Silva.
Abstract Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge of dipteran fauna from this region is grossly lacking. This applies even to the most studied families, such as Drosophilidae. Despite its prominence, most aspects of the biology of these insects are still poorly understood, especially those linked to natural communities. Field studies on drosophilids are highly biased towards fruit-breeding species. Flower-breeding drosophilids, however, are worldwide distributed, especially in tropical regions, although being mostly neglected. The present paper shows the results of a biodiversity inventory of flower-breeding drosophilids carried out in several localities in Brazil, based on samples of 125 plant...

Abstract We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.

The objective of this work was to validate microsatellite markers associated with resistance to soybean cyst nematode (Heterodera glycines Ichinohe) races 3 and 14, in soybean (Glycine max L.) genotypes, for use in marker-assisted selection (MAS) programs. Microsatellites of soybean linkage groups A2, D2 and G were tested in two populations, and their selection efficiencies were determined. The populations were 65 F2:3 families from Msoy8001 (resistant) x Conquista (susceptible) cross, and 66 F2:3 families of S5995 (resistant) x Renascença (susceptible) cross, evaluated for resistance to races 3 and 14, respectively. Families with female index up to 30% were considered moderately resistant. Markers of A2 and G linkage groups were associated with resistance...

Provedor de dados: 86
Autores: ANUNCIAÇÃO,CARLOS EDUARDO; ASTOLFI-FILHO,SPARTACO.
GC-rich molecular minisatellite probes isolated from the human genome have presented a poor ability for individualization in horses. In this study new DNA sequences were isolated which could be used in paternity tests in horses. Genomic DNA from "Mangalarga-Marchador" horses was treated with restriction enzymes that preferentially digest non-repetitive sequences, so preserving the structure where mini and microsatellites are located. Four clones (S01, S05, S07 and S09) selected from a genomic library screened with a (TG)n oligonucleotide showed similar hybridization profiles generating bands of DNA-fingerprinting type. Using these probes the individualization power obtained was 10-8, which is 10(5)fold higher than that obtained with M13, another GC-rich...

Inheritance of seed coat color in sesame
Provedor de dados: 86
Autores: Laurentin,Hernán; Benítez,Tonis.
The objective of this work was to determine the inheritance mode of seed coat color in sesame. Two crosses and their reciprocals were performed: UCLA37 x UCV3 and UCLA90 x UCV3, of which UCLA37 and UCLA90 are white seed, and UCV3 is brown seed. Results of reciprocal crosses within each cross were identical: F1 seeds had the same phenotype as the maternal parent, and F2 resulted in the phenotype brown color. These results are consistent only with the model in which the maternal effect is the responsible for this trait. This model was validated by recording the seed coat color of 100 F2 plants (F3 seeds) from each cross with its reciprocal, in which the 3:1 expected ratio for plants producing brown and white seeds was tested with the chi-square test.

The objective of this work was to estimate the mating system parameters of a andiroba (Carapa guianensis) population using microsatellite markers and the mixed and correlated mating models. Twelve open‑pollinated progeny arrays of 15 individuals were sampled in an area with C. guianensis estimated density of 25.7 trees per hectare. Overall, the species has a mixed reproductive system, with a predominance of outcrossing. The multilocus outcrossing rate (t m = 0.862) was significantly lower than the unity, indicating that self‑pollination occurred. The rate of biparental inbreeding was substantial (t m ‑ t s = 0.134) and significantly different from zero. The correlation of selfing within progenies was high (r s = 0.635), indicating variation in the...

Abstract: The objective of this work was to build weighted correlation networks, in order to discover correlation structures and link patterns among 28 morphoagronomic traits of chili pepper related to seedling, plant, inflorescence, and fruit. Phenotypic and genotypic information of 16 Capsicum genotypes were analyzed. Correlation structures and link patterns can be easily identified in the matrices using the Fruchterman-Reingold algorithm with correlation network information. Both types of correlations showed the same general link pattern among fruit traits, with high broad-sense heritability values and high aptitude of the genotypes for agronomic and ornamental breeding. Leaf dimensions are correlated with a cluster of fruit traits. Correlation networks...

- The objective of this work was to determine the total protein profile and the contents of the four major protein fractions (albumin, globulin, prolamin and glutelin) and of the amino acids in the endosperm of the rice wild species Oryza glumaepatula. The experiment was performed with 29 accessions of this species, collected from 13 Brazilian locations, and two commercial cultivars. Protein samples were prepared using dried, polished, and ground grains to obtain homogeneous, dry flour used in the preparation of extracts. Oryza glumaepatula accessions were identified with the highest levels of total protein, albumin and glutelin protein fractions, and amino acids (with the exception of tryptophan) in comparison to the two analized rice cultivars. The...

Autores: Moraes,José Carlos Ferrugem; Jaume,Carlos Miguel; Souza,Carlos José Hoff de.
The relationship between changes in body condition score (BCS) during the postpartum and fertility in beef cows suckling calves under extensive conditions were investigated. Cows were subjected to four BCS evaluations over the postpartum period, starting around one month after calving. In the second evaluation cows were treated with medroxy-progesterone acetate impregnated pessaries and received an injection of estradiol benzoate. At the third evaluation, pessaries were removed and calves were separated from the cows for 96 hours, during which time estrous was observed twice a day, and animals artificially inseminated 12 hours after detection. When calves returned to their dams, bulls were introduced until a 60-day mating period was reached. The...

Selection via simulated individual BLUP based on family genotypic effects in sugarcane
Provedor de dados: 86
Autores: Resende,Marcos Deon Vilela de; Barbosa,Márcio Henrique Pereira.
The objective of this work was to propose a new selection strategy for the initial stages of sugarcane improvement, based on the methodology 'simulated individual BLUP (BLUPIS)', which promotes a dynamic allocation of individuals selected in each full-sib family, using BLUP as a base for both the genotypic effects of the referred families and plot effects. The method proposed applies to single full-sib families or those obtained from unbalanced or balanced diallel crosses, half-sib families and self-pollinated families. BLUPIS indicates the number of individuals to be selected within each family, the total number of clones to be advanced, and the number of families to contribute with selected individuals. Correlation between BLUPIS and true BLUP was 0.96,...

Autores: Tokasi,S.; Bannayan Aval,M.; Mashhadi,H.R.; Ghanbari,Ali.
Parasitic weed species of the genus Orobanche are serious threat for the production of several crops in Europe, Africa and Asia. Research on resistant host plant varieties is one of the most effective management strategies for this parasitic weed. In this study, the susceptibility of twenty-nine tomato varieties to broomrape infection (Orobanche aegyptiaca) under greenhouse conditions was investigated. The employed experimental design was completely randomized with three replications. Differences in susceptibility to infection were monitored among tomato varieties based on their difference in the number of emerged shoots of broomrape and broomrape dry weight (shoots and tubercles). Date of Orobanche emergence varied over a period of 3 to 30 days between...

Plant Breeding: A Long-term Strategy for the Control of Zinc Deficiency in Vulnerable Populations
Provedor de dados: 31
Autores: Ruel,   Marie T.; Bouis,   Howarth E.
Because trace minerals are important not only for human nutrition, but for plant nutrition as well, plant breeding holds great promise for making a significant low-cost and sustainable contribution to reducing micronutrient deficiencies in humans, and may have important spinoff effects for increasing farm productivity in developing countries in an environmentally beneficial way. This paper describes ongoing plant breeding research that could increase the intake of bioavailable zinc from food staple crops among vulnerable populations in developing countries. The three most promising plant breeding strategies to achieve this goal are (1) increasing the concentration of zinc in the plant, (2) reducing the amount of phytic acid (a strong inhibitor of zinc...

Cooperatives' Role in the Artificial Insemination Industry
Provedor de dados: 31
Autores: Hogeland,   Julie A.
The artificial insemination industry provides breeding products and services for both dairy and beef cattle. Two-thirds of the industry is organized as producer-owned cooperatives. The industry has been so highly successful in meeting the needs of producers for a high-quality reliable product that the United States is the world's leading producer and exporter of bull semen. Yet, more bulls (and consequently more cooperatives) are available than are technically needed for genetic variation and breeding requirements. The result of such product proliferation is higher semen prices and excessive costs for inventory, distribution, and marketing. To maintain their prominent role in the industry, the 22 cooperatives need to consolidate to streamline the...

The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75% of years, rice farmers suffer losses between 0.5 and 2.5 t/ha. Research is being undertaken to identify overseas rice varieties, that are cold tolerant under the local weather conditions and by using those genotypes as parent material, develop cold tolerance varieties of rice. A yield simulation model was used to measure reduction in losses due to cold at different minimum threshold temperatures, while the SAMBOY Rice model was used to measure the costs and returns...

Autores: Souza,   Celia de; Souza,   Jose Carlos de; Faria,   Ana Cristina de.
The present article joint costs attribution methods applied to rabbit breeding activity are discussed. In this activity, as well as in other agrobusiness, the costs incurred along the initial phases of the production cannot be directly imputed to the several products generated up to the separation point, but after this point. That is due to the diversity of characteristics presented by the several coproducts and by-products obtained in rabbit breeding. Through a bibliographical research the main methods of attribution of joint costs were verified, and from a case study it is tried to demonstrate the application of these methods in the rabbit breeding. It was verified that the several existent methods are based in tracking of the general production costs...

Autores: Sogut,B; Celik,S; Ayasan,T; Inci,H.
ABSTRACT The objective of this study was to identify the growth curve of live weight of turkeys reared in different systems (intensive and free- range) with the best mathematical model. To achieve this goal, the live weight of male and female turkeys (Large White) reared for 0-18 weeks were used. Logistic, Gompertz, Von Bertalanffy, and Gauss were used to determine the best model for the turkeys. In comparison of the models, values of Coefficient of Determination (R2), Mean Squares of Error (MSE) and Model Efficiency (ME) were used. In Von Bertalanffy model, the coefficient of determinations for males and females were found as 0.9974 and 0.99915 in intensive system and 0.9794 and 0.9804 in Free-Range system, respectively. As a result of this study, because...

Provedor de dados: 92
Autores: Souza,Carlos Alberto S.; Prezoto,Fábio; Lima,Mauro Sérgio C.S.; Pederassi,Jonas.
A species' mating system depends on its spatial distribution and temporal availability of mating opportunities, as well as on the resources that create these opportunities. In addition, for many species, courtship is driven by specific behaviors that precede and follow copulation. Although Sphex ingens is a taxonomically well known species of digger wasp, its ecology and behavior remain poorly known. Hence, we analyzed patterns and trends of sexual behavior, in order to understand whether courtship can persist in a polygamous mating system. We monitored by video wasp populations in Ilha Grande, southeastern Brazil. Based on the observed behaviors, we calculated stochastic probabilities with a Markov chain to infer on behavioral trends. We recorded four...

Evaluation of lignin content of soybean seed coat stored in a controlled environment
Provedor de dados: 95
Autores: Krzyzanowski,Francisco Carlos; Franca Neto,José de Barros; Mandarino,Jose Marcos Gontijo; Kaster,Milton.
Breeding soybean for high seed quality is an important approach for developing cultivars for tropical regions, and the lignin content in the seed coat is one of the screening parameters for this trait. Considering that many breeding lines are evaluated in each growing season using the presently recommended method for lignin determination, a long period is required for the evaluation of the whole breeding program. This time limitation may influence lignin content assessment, if lignin is degraded during storage. This research reported was designed to determine whether lignin was degraded in the seed coat of soybean seed cultivars stored for one year in a controlled environment (10°C temperature and 50% air relative humidity). Seeds of 12 selected soybean...

Autores: Pichorim,Mauro.
The nesting success of three colonies of Streptoprocne biscutata (Sclater, 1866), and the influence of clutch and brood size on nesting success of species were studied. Overall, apparent nesting success was 58% and Mayfield nesting success was 53%. Nest survival during incubation (64%) was lower than during the nestling period (83%). During incubation, clutches were lost to rain, desertion, predation, egg ejection, egg damage, and egg disappearance. During the nestling period, losses occurred due to offspring disappearance, nestling death by starvation, predation and falling. During both incubation and nestling periods, predation was low, while egg ejections and nestling starvation were the main causes of nest failure. Nest survival during incubation was...

ABSTRACT Describing the interactions among cavity breeders is key to understanding their breeding ecology. In this study the temporal difference in cavity use between the great tit, Parus major (Linnaeus, 1758) and the small Japanese field mice, Apodemus argenteus (Temminck, 1845) is investigated, as a first step for clarifying the interaction between bird and mammal cavity breeders. Forty-seven nest boxes were installed on tree trunks in two urban forests of Hokkaido Island, Japan, and the breeding nests of tits and mice were found in 34 and 11 boxes, respectively. The tits used the nest boxes throughout the breeding season, from May to July. In contrast, mice breeding nests were found in the last half of the breeding season, from July to October. Our...

Persistency of lactation using random regression models and different fixed regression modeling approaches
Provedor de dados: 96
Autores: Cobuci,Jaime Araujo; Costa,Claudio Napolis.
Milk yield test-day records on the first three lactations of 25,500 Holstein cows were used to estimate genetic parameters and predict breeding values for nine measures of persistency and 305-d milk yield in a random regression animal model using two criteria to define the fixed regression. Legendre polynomials of fourth and fifth orders were used to model the fixed and random regressions of lactation curves. The fixed regressions were adjusted for average milk yield on populations (single) or subpopulations (multiple) formed by cows that calved at the same age and in the same season. Akaike Information (AIC) and Bayesian Information (BIC) criteria indicated that models with multiple regression lactation curves had the best fit to test-day milk records of...

Application of molecular information in sustainable animal breeding
Provedor de dados: 96
Autores: Koning,Dirk-Jan de.
Livestock genomics is aimed at dissecting the genetic control of variation in economically important trait, such as disease resistance and product yield/quality. Unraveling the genetic control of such complex traits remains very challenging but farm animals are now well placed to bridge the gap between human biology and traditional model species. Livestock species share with model species the benefits of controlled breeding, while their biology is often much closer to that of humans. Livestock genetics can exploit the abundant genetic variation between divergent breeds as well as segregating variation within breeds, thus getting the best of both worlds. Large numbers of QTL have been detected for a variety of traits but for only a handful has the...

Provedor de dados: 96
Autores: Amado,Marina Freire; Xavier,Diego Batista; Boere,Vanner; Torres-Pereira,Carla; McManus,Concepta; Bernal,Francisco Ernesto Moreno.
The behaviour of ostrich chicks bred in captivity was studied by using groups with 30 birds in five age groups: from 10 to 40 days of age; from 41 to 60 days of age; from 61 to 90 days of age; from 91 to 120 days of age and from 121 to 150 days of age. Six birds at each age were ringed around one of their feet and observed for four consecutive days for eight hours daily in three periods (in the morning, at noon and in the afternoon), following the "one-zero" method for sampling. The order for observation of behaviour of the six selected birds was performed randomly at every thirty minutes, totalling 16 periods or 80 minutes/bird/day. Fourteen types of behaviour were observed. There were differences among ages for behaviour like standing, walking, running,...

Selective breeding of Arabian and Thoroughbred racehorses in Algeria: perceptions, objectives and practices of owners-breeders
Provedor de dados: 96
Autores: Tennah,Safia; Farnir,Frédéric; Kafidi,Nacerredine; Nsangou,Ibrahim Njikam; Leroy,Pascal; Antoine-Moussiaux,Nicolas.
This survey, conducted with 461 racehorse owners-breeders in Algeria between 2009 and 2011, investigates their perceptions, objectives and practices regarding selective breeding. Racehorse breeding is a full-time professional activity for a third of interviewees. The holdings are small-sized with 77% owning one or two mares. The regular practice of mating is here used to categorize breeders according to their degree of professionalization (38.4% professional vs. 61.6% occasional breeders). Experience in the sector was also used to classify breeders, considering as "junior" the breeders under 10 years experience (38.8%) and as "senior" those above 10 years (61.2%). More than professionalization, experience shows a significant impact on practices and...

Autores: Weiler,Roberto Luis; Dall’Agnol,Miguel; Simioni,Carine; Krycki,Karine Cristina; Dahmer,Nair; Guerra,Divanilde.
ABSTRACT The aim of this study was to determine the mode of reproduction of a hybrid progeny derived from intraspecific crosses of Paspalum notatum through cytoembryological analysis and use of RAPD (random amplification of polymorphic DNA) molecular markers. Cytoembryological analysis allowed identification of the mode of reproduction of 28 plants that were selected after agronomic productivity evaluations. Of these, 19 had embryo sac morphology compatible with an apomictic mode of reproduction and nine had embryo sac morphology compatible with a sexual mode of reproduction. Meanwhile, molecular marker analysis for 194 individuals showed 54 sexual and 140 apomictic plants; of the 28 plants analyzed by the two methods, ten results (35.7%) were in...

Genetic improvement of beef cattle through opportunities in genomics
Provedor de dados: 96
Autores: Miller,Stephen.
Genomics will improve the efficiency of beef cattle genetic improvement programs through the incorporation of genomic predictions into traditional genetic evaluations. The global dairy cattle breeding industry has been changed considerably in the last year through the implementation of genomic selection. Now proven to work in dairy cattle breeding, the challenge remains for the beef industry to successfully implement this technology. The primary challenge in beef cattle is the required resource population that relates genomic profile to phenotypic performance, which is quite large and its establishment will require collaboration or a significant investment by any one enterprise. Another challenge in beef cattle is the requirement for genomic predictions to...

ABSTRACT This study evaluated morphometric and ultrasound information of tilapia (O. niloticus) breeders through multivariate analysis. We applied correlation, clustering, and principal component analysis to a dataset composed of information from 222 male and female breeders of the improved GIFT strain. The body weight, objective of the breeding program, showed a high positive correlation with most of the morphometric parameters. The formation of clusters indicated characteristics responsible for muscle composition and carcass weight. Some characteristics showed a high correlation, such as body weight and fillet weight (0.98 and 0.94 for females and males, respectively), and a high contribution to the explanation of data variability; of the total...

Value of genomics in breeding objectives for beef cattle
Provedor de dados: 96
Autores: MacNeil,Michael D.
ABSTRACT The objective of this research was to discern the contribution of genomic information to multiple-trait breeding objectives and thus understand the economic value of that information. True genetic values were simulated for each of n, possibly correlated, traits. These true genetic values, combined with uncorrelated random noise, resulted in both genomic and phenotypic estimated breeding values, EBVg and EBVp, respectively. The separate EBV were then merged (blended) as a function of their respective accuracies to produce a unified EBV for each of the n traits. Finally, for each simulated animal (N = 10000), the sum of products of economic weights and EBV was calculated to predict the economic value (net merit) of the individual. Accuracies of the...

Autores: CARSON,HAMPTON L.
This is a personal essay commemorating Brncic as a keen naturalist/evolutionist in the best Darwinian sense. His innate curiosity, so important in a scientist, led him to the discovery of cenain unique drosophilid flies in Chile. The life cycle of one species of flower-fly (Drosophila flavopilosa) is of special interest. Females oviposit in fresh flowers of a solanaceous plant that is widespread in Chilean valleys. Twenty years of combined ecological and genetic work, carried out on this species, pioneers the use of a highly specialized Drosophila species in the study of population genetics and evolution. Many eco-genetic features are revealed that are important supplements to observations made on the widely-studied generalist species of the genus

Autores: Caixeta,Débora Santos; Fritsche-Neto,Roberto; Granato,Ítalo Stefanine Correia; Oliveira,Lucimar Rodrigues de; Galvão,João Carlos Cardoso.
Several studies to evaluate nitrogen use efficiency (NUE) have been carried out using early growth stages. However, there are no scientific reports on the ideal stage for evaluation and on which characteristics have the highest correlation with the NUE at that stage. The aim therefore was to identify the phenological stages and secondary characteristics which maximize accuracy in early indirect selection for NUE in maize. To do this, three endogamic maize strains were evaluated in a completely randomised design with five replications, in a triple factorial scheme (strains x N levels x phenological stage), at two contrasting nitrogen levels: low and high nitrogen. The plants were evaluated at five growth stages: stage nine (V9), with 14 fully-developed...

Provedor de dados: 124
Autores: Vieira,Rafael Augusto; Scapim,Carlos Alberto; Tessmann,Dauri José; Hata,Fernando Teruhiko.
Ten popcorn inbred lines were crossed in a circulant partial diallel matching scheme (group of lines derived from IAC 112 × group of lines from 'Zaeli'). The hybrids were evaluated in respect to grain yield (GY), popping expansion (PE), and resistance to southern rust (Puccinia polysora, Pp), in randomized block design, with three replications. Data was examined by analyses of variance and Kempthorne and Curnow's diallel analysis. General combining ability (GCA) was significant (p &lt; 0.10) in the set 2-Zaeli for GY, PE, and partial resistance to Pp. This indicated that additive gene effects are predominant, and therefore breeding methods of recurrent selection are recommended. However, none of lines had outstanding GCA for GY and PE. The line P8.5 was...

RELATIONSHIP BETWEEN RADICAL INFESTATION OF Hylastinus obscurus (MARSHAM) AND THE YIELD OF CULTIVARS AND EXPERIMENTAL LINES OF RED CLOVER (Trifolium pratense L.)
Provedor de dados: 127
Autores: Alarcón,Daniela; Ortega,Fernando; Perich,Fernando; Fernando,Pardo; Parra,Leonardo; Quiroz,Andrés.
Red clover (Trifolium pratense L.) is a valuable forage legume grown alone or in mixture with grasses in temperate regions of the world. Red clover is adapted to a wide range of soil types, pH levels, environmental and management conditions. However, the main limitation of this species is the lack of persistence related to the high mortality of plants. In Chile the main biotic factor affecting survival of plants is the root borer Hylastinus obscurus (Marsham) (Coleóptera; Scolytidae). In 1989, a red clover (T. pratense L.) breeding program was started at Carillanca Research Center of the Institute of Agricultural Research (INIA), Chile, with the main objectives of improving the survival of plants, forage yield and persistence.

Autores: Lorentz,Leandro Homrich; Gaya,Leila de Genova; Lunedo,Raquel; Ferraz,José Bento Sterman; Rezende,Fernanda Marcondes de; Michelan Filho,Tércio.
Breast weight has great economic importance in poultry industry, and may be associated with other variables. This work aimed to estimate phenotypic correlations between performance (live body weight at 7 and 28 days, and at slaughter, and depth of the breast muscle measured by ultrasonography), carcass (eviscerated body weight and leg weight) and body composition (heart, liver and abdominal fat weight) traits in a broiler line, and quantify the direct and indirect influence of these traits on breast weight. Path analysis was used by expanding the matrix of partial correlation in coefficients which give the direct influence of one trait on another, regardless the effect of the other traits. The simultaneous maintenance of live body weight at slaughter and...

Autores: Cargnin,Adeliano; Souza,Moacil Alves de; Fronza,Vanoli; Fogaça,Cláudia Martellet.
Producers need wheat cultivars adapted to the predominant climate conditions of the end of the rainy period. Having this in mind, EPAMIG (Agriculture and Livestock Research Institute of Minas Gerais) has been developing a wheat genetic improvement program since 1976, and the estimates of the genetic improvement established by the breeding programs could be useful to quantify their efficiency. This study focused on the quantification of the genetic progress achieved by these improvement programs of dryland wheat in the Brazilian-savanna between 1976 and 2005. The efficiency of these programs was evaluated based on grain yield data of VCU (Value for Cultivation and Use) trials conducted at ten locations in the Minas Gerais State, Brazil. The mean estimated...

ABSTRACT Genomic selection (GS) emphasizes the simultaneous prediction of the genetic effects of thousands of scattered markers over the genome. Several statistical methodologies have been used in GS for the prediction of genetic merit. In general, such methodologies require certain assumptions about the data, such as the normality of the distribution of phenotypic values. To circumvent the non-normality of phenotypic values, the literature suggests the use of Bayesian Generalized Linear Regression (GBLASSO). Another alternative is the models based on machine learning, represented by methodologies such as Artificial Neural Networks (ANN), Decision Trees (DT) and related possible refinements such as Bagging, Random Forest and Boosting. This study aimed to...

ABSTRACT: The methods of Annicchiarico (1992) and Cruz et al. (1989) are widely used in phenotypic adaptability and stability analyses in plant breeding. In spite of the importance of these methodologies, their parameters are difficult to interpret. The aim of this research was to develop fuzzy controllers to automate the decision-making process employed by adaptability and stability studies following the methods adopted by Annicchiarico (1992) and Cruz et al. (1989) and check their efficiency using experimental data from common bean cultivars. Fuzzy controllers have been developed based on the Mamdani inference system proposed by these two methods of adaptability and stability studies. For the first fuzzy controller parameters were considered favorable...

Autores: Dahmer,Nair; Schifino-Wittmann,Maria Teresa; Dall'Agnol,Miguel; Castro,Biane de.
Several species of the genus Paspalum L. are important forages, due their to quality, productivity and tolerance to environmental stresses. Chromosome numbers, meiotic configurations and pollen fertility were evaluated in a collection of 85 accessions of Paspalum notatum Flügge and in seven accessions of Pensacola (P. notatum var saurae). All P. notatum accessions were tetraploid, with 2n = 4x = 40, except one diploid accession, considered as an escape of Pensacola. All Pensacola plants had 2n = 2x = 20. Meiotic configurations at diakinesis and metaphase I varied among tetraploid accessions, from plants with only bivalents to plants with high frequency of quadrivalents. Pollen fertility varied from 82.5 to 95.9% among diploid accessions and from 72.4 to...

Sexual polyploidization in red clover
Provedor de dados: 63
Autores: Simioni,Carine; Schifino-Wittmann,Maria Teresa; Dall'Agnol,Miguel.
Because sexual polyploidization broadens genetic basis and supply plant breeders with more variability for the selection process, it can be useful in red clover breeding. This paper reports results of three crossing cycles, starting from a parental generation of tetraploid red clover plants (female parent), and diploids from the Quiñiqueli cultivar, selected for production of more than 1% of giant pollen grains (male parent) aiming to obtain tetraploid plants to be used in red clover breeding programs. Crosses in the next generations were performed by mutual cross-pollinations. Chromosome number chimerism and high pollen sterility were detected in F1, F2 and F3, but there was a trend towards increasing seed production and seed viability along the...

ABSTRACT: Artificial neural networks (ANN) are computational models inspired by the neural systems of living beings capable of learning from examples and using them to solve problems such as non-linear prediction, and pattern recognition, in addition to several other applications. In this study, ANN were used to predict the value of the area under the disease progress curve (AUDPC) for the tomato late blight pathosystem. The AUDPC is widely used by epidemiologic studies of polycyclic diseases, especially those regarding quantitative resistance of genotypes. However, a series of six evaluations over time is necessary to obtain the final area value for this pathosystem. This study aimed to investigate the utilization of ANN to construct an AUDPC in the...

ABSTRACT: The intense selection process for economic traits conducted by the poultry breeding programs has been caused several changes in broiler meat quality. A database belonging to a selection program of a broiler male line was used to estimate heritability and genetic correlations for feed conversion ratio and meat quality traits, which were: initial and final pH, lightness, drip loss, thawing loss and shear force. Two-trait analyses were performed and the components of co(variance) and genetic parameters were determined using the Bayesian approach and the GIBBS3F90 software. The heritability estimate found for feed conversion ratio (0.52) showed high influence of direct additive genetic effects on the expression of this trait; therefore, this trait is...

Autores: Pereira,Laís Andrade; Ramalho,Magno Antonio Patto; Abreu,Ângela de Fátima Barbosa; Guilherme,Scheila Roberta.
ABSTRACT: In common bean (Phaseolus vulgaris) harvesting is carried out in the field. It is therefore necessary that cultivars be tolerant to viviparity, i.e., germination of grains still in the pods. Study of the percentage of germination of beans in the pods under laboratory conditions, where humidity content is high, has been proposed. Furthermore, under question is whether the thickness of the pod wall affects water uptake by the pods and, consequently, viviparity. Thus, the aim of the present study was to verify if there is variance among progenies for viviparity and if it is influenced by pod thickness. We assessed the parents, Pérola and ESAL 686, the F1, and a number of segregating generations in two crop seasons, in relation to the percentage of...

A short review: Comparisons of high-throughput phenotyping methods for detecting drought tolerance
Provedor de dados: 63
Autores: Kim,Jaeyoung; Kim,Ki-Seung; Kim,Yoonha; Chung,Yong Suk.
ABSTRACT Drought is a major threat worldwide for crop production, especially due to the rapid climate changes. Current drought solutions involve improving irrigation system, rainwater harvesting, damming, cloud seeding, and changes of cultivation methods. Despite effective, each solution has economic, environmental, and temporal drawbacks. Among all solutions, the most effective, inexpensive and manageable method is the use of drought-tolerant cultivars via plant breeding. However, conventional plant breeding is a time-consuming and laborious task, especially for phenotypic data acquisition of target traits of numerous progenies. High-throughput phenotyping (HTP) is a recently developed method and has potential to overcome the mentioned issues. HTP offers...

Although much appreciated in Brazil, commercial popcorn is currently cropped on a fairly small scale. A number of problems need to be solved to increase production, notably the obtaintion of seeds with good agronomic traits and good culinary characteristics. With the objective of developing superior genotypes in popcorn, a second cycle of intrapopulation recurrent selection based on inbred S1 families was carried out. From the first cycle of selection over the UNB-2U population, 222 S1 families were obtained, which were then divided into six sets and evaluated in a randomized complete block design with two replications within the sets. Experiments were carried out in two Brazilian localities. The analysis of variance revealed environmental effects for all...

Reproductive behavior of Cycloramphus dubius Miranda-Ribeiro (Amphibia, Anura, Leptodactylidae)
Provedor de dados: 104
Autores: Giaretta,Ariovaldo A; Cardoso,Adão J.
Cycloramphus dubius Miranda-Ribeiro. 1920 is a frog species from the coastal Atlantic Forest in Southeastern Brazil. It uses waterfalls of forested rivulets as breeding sites. The eggs are placed outside of water, between rock crevices or roots constantly wetted by water dripping. Clutches have about 60 eggs, and the tadpoles grow attached to rocks, out of water. Males of this species exhibit parental care, biting and/or pushing away strange objects approaching the egg masses. Two types of calls were identified in the spectrograms. The "advertisement calls" consist of juxtaposed pulses lasting 200ms; the "aggressive calls", also have the short pulses structure, and last around 300ms. The aggressive calls are emitted during territorial invasion.

Larvae of Culex eduardoi, Culex bigoti, Limatus durhamii and Toxorhynchites were collected in a tyre that had been placed in a wood by a river bank. These larvae were present coexisting and in an individualized form. It was observed that Toxorhynchites, Culex bigoti and Limatus durhamii were efficient in reducing the other two species's population. Culex bigoti and Toxorhynchites showed preference for Culex quinquefasciatus larvae, while Limatus durhamii preferred Culex eduardoi. The most efficient predator was Toxorhynchites, and the least efficient was Limatus durhamii. The reduction of the preys' population density was statistically meaningful in the face of the three species considered as predators.

ABSTRACT Tambaqui, Colossoma macropomum, is one of the most produced species in Brazilian fish farming, which has boosted the development of new technologies to increase its productivity. The aim of this study was to evaluate production performance in two second-generation tambaqui stocks selectively bred for weight gain in a semi-intensive rearing system and assess its influence on total production cost. We analyzed 300 fish (initial mean weight and standard length of 160 g and 17 cm, respectively) of two families (A and B, 150 fish each). The fish were individually marked with microchips and stocked in an 800-m2 excavated pond. For economic analysis, the obtained performance data were extrapolated for a fish farm with a 10-ha pond, adopting the Total...

ABSTRACT The expansion of the genetic base of cultivated materials is an ongoing activity of the cupuassu (Theobroma grandiflorum) breeding program. However, the parents involved need to be genotypically and phenotypically characterized to ensure compatibility of crossings, as well as to assist in the selection of more promising individuals for hybridization. This study aimed to identify and select T. grandiflorum clones that are compatible and genetically divergent using tools such as the estimates of genotypic, phenotypic, and combined distances, as well as the compatibility rates among clones. The genetic distance analysis of the clones was performed with 14 heterologous microsatellite primers of cocoa (Theobroma cacao) that amplify the DNA of cupuassu....

Pollination biology of Paliavana tenuiflora (Gesneriaceae: Sinningeae) in Northeastern Brazil
Provedor de dados: 39
Autores: Ferreira,Patrícia Alves; Viana,Blandina Felipe.
In this study the floral biology, breeding system, visitors and pollinators of Paliavana tenuiflora were analyzed in campos rupestres in the Chapada Diamantina, Mucugê, Bahia, Brazil. Paliavana tenuiflora is a shrub with blue-violet, bell-shaped flowers, with anthesis at 11:00 h; the flowers last about six days. Large amounts of nectar are produced (volume average 15.5µL, concentration 22.7% and sugar content 5.0 mg mL-1). The amount of nectar is not related to the time of day, but concentration varied with volume. The species is self-compatible, but fruit set depends on pollinators. Although nectar is available by day and night, flowers of P. tenuiflora fit the bee pollination syndrome, and are actually pollinated by Bombusbrevivillus. However, the...

Intrafloral phenology of Trifolium polymorphum Poir. (Leguminosae) aerial flowers and reproductive implications
Provedor de dados: 39
Autores: Speroni,Gabriela; Izaguirre,Primavera; Bernardello,Gabriel; Franco,Jorge.
Trifolium polymorphum is an amphicarpic species that grows in Uruguay, Argentina, Brazil, Paraguay and Chile. Underground flowers are cleistogamous, obligately autogamous and morphologically highly modified in structure and function. Aerial flowers are chasmogamous, and as mentioned in earlier literature, either allogamous or autogamous. The aim of this study is to identify flower characteristics that facilitate or prevent autogamous or allogamous processes. Floral phenology stages are thus studied in correlation with estimated models of aerial flower development, pollen viability and stigmatic receptivity in three Uruguayan T. polymorphum populations. Flower longevity and development (length, width, and anther-stigma distance), anthesis and anther...

Autores: Silva,André Luiz Gomes da; Pinheiro,Maria Célia Bezerra.
Eugenia uniflora,E. punicifolia,E. neonitida and E. rotundifolia are perennial species, usually shrubs, which occur in the restinga of the Grumari Natural Municipal Park, in western Rio de Janeiro, Brazil. They have Papaver-type pollen-flowers that are hermaphrodite, polystemonous and pollinated mainly by bees. An assessment of the breeding systems showed that only E. uniflora and E. punicifolia are self-compatible. The fruit/flower, seed/ovule and seed/fruit ratios were calculated for each species. Fruit and seed predators were identified and predation rates were estimated. Total reproductive success for each species in the restinga was extremely low. In order to have one viable seed free from herbivore attack at the end of the reproductive process, the...

Autores: Viganó, Joselaine; Braccini, Alessandro Lucca; Schuster, Ivan; Menezes, Vanessa Maria Pereira Silva.
The present study aimed at pyramiding ASR-resistance genes through microsatellite (SSR) marker-assisted selection (MAS) and demonstrating the pyramiding steps. To obtain the first generation of gene pyramiding, crosses were made between introduced plants (PI’s), which have the genes Rpp1, Rpp2, Rpp3, Rpp4, and Rpp5. F1 plants from the initial crosses were intercrossed to obtain plants with the four resistance genes (second pyramiding generation). Plants selected from this second generation were again intercrossed (third pyramiding generation) to increase the number of pyramided genes. For MAS, we used informative SSR markers in each cross. SSR markers were considered informative when the source resistance allele containing the target gene could be followed...

 Sorghum (Sorghum bicolor L. Moench) is one of the most important cereal crops in the world. In Brazil, the acreage of grain sorghum during off-season is quite expansive. Most of this area is the Cerrado, a Brazilian biome that is similar to a Savannah and is characterized by high acidity and soluble aluminum at toxic levels for plants. The aluminum acts as a limiting factor in achieving high yields. The purpose of this work was to phenotype sorghum hybrids for aluminum tolerance. Eighteen hybrids were evaluated in a nutrient solution containing {0} or {27} µM Al3+. The work was carried out in a growth chamber at the Embrapa Maize and Sorghum, from April 4 to May 30, 2014. The lines ATF 13B (susceptible) and ATF 14B (tolerant) were used as check cultivars....

In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction in precision. Therefore, the aim of this study was to estimate the size of the experimental plot for evaluation of coffee yield. We evaluated two experiments for validation of cultivars with 12 treatments set up in a randomized complete block design with three replicates and plots composed of 50 plants. Each plant was considered as a basic unit. Estimates of ideal plot size were made by maximum curvature of the coefficient of variation, linear-plateau segmented model and by the resampling methods. We discussed the variations in the...

The study was carried out with the objective of verifying which measures and morphometric ratios are more directly related to the body yield of Nile tilapia, Oreochromis niloticus, in two weight classes. Data were analyzed from 257 specimens of tilapia divided into two weight classes: p1 = 400 to 599  g and p2 = 600 to 900 g. The morphometric measurements standard length (SL), head length (HL), body height (BH) and body width (BW), and the ratios of these measures (HL / SL, BH / SL, BW / SL, HL / BH, BW / BH, BW / HL) were evaluated. The following body yields were calculated: carcass (RCAR), fillet (RFILE) and head (RCAB). The data were initially submitted to the "stepwise" procedure to eliminate problems of multicollinearity among the morphometric...

Provedor de dados: 114
Autores: Occhiuto,P.N; Peralta,I.E; Asprelli,P.D; Galmarini,C.R.
Paprika production is concentrated in Northwestern Argentina, where around 1500 ha are annually grown. Farmers mainly from Andean valleys, maintain their local landraces or &amp;#8220;criollas&amp;#8221; under different environmental conditions, using their farming traditions and selection criteria. These traditional varieties represent valuable genetic resources for conservation and selection of agronomical and quality traits. Between 2005 and 2007 eight collecting trips were made to Northwestern Argentina in order to recover local germplasm. As a result, five hundred new vegetable seed samples have been incorporated into the Germplasm Bank. Among these accessions 32 belong to Capsicum, the majority for paprika production, that were evaluated in field...

Population dynamics and reproductive phenology of a harvestman in a tidal freshwater wetland
Provedor de dados: 42
Autores: IGLESIAS,PATRICIA P.; PEREYRA,MARTÍN O.
Abstract  There is a great amount of ecological information for terrestrial arthropods in several types of habitats, but few studies have focused on populations living in tidal freshwater wetlands. During a two-year field survey, we studied the temporal dynamics of the harvestman Discocyrtus prospicuus inhabiting a freshwater wetland exposed to predictable tides and unpredictable floods. We also explored the effects of temperature, precipitation, and tide level on the population dynamics and reproductive phenology. Our findings are markedly different from those reported in other harvestman species living in different habitats and also from conspecific populations living in the mainland. Adults, subadults, and juveniles remain active throughout the year,...

Reproductive phenology of the American Bullfrog in subtropical Brazil: photoperiod as a main determinant of seasonal activity
Provedor de dados: 42
Autores: MEDEIROS,CAMILA I.; BOTH,CAMILA; KAEFER,IGOR L.; CECHIN,SONIA Z.
ABSTRACT The North American bullfrog Lithobates catesbeianus continues to invade ecosystems worldwide, potentially causing population declines and even extinctions. Within its native distribution, bullfrogs show prolonged reproductive seasons and high fertility. However, data on breeding biology of bullfrogs ex-situ in invaded localities mainly comes from anecdotal reports. Understanding how invasive species are adjusting their life histories to new colonized environments is important for conservation purposes. Here we describe temporal and spatial abundance, calling activity, spawning and tadpole distribution of bullfrogs in southern Brazil. Eighteen samplings occurred during one year. The abundance of individuals was positively related to longer...

Autores: Seixas Filho,J.T.; Santana,A.C.; Martins,A.C.P.F.; Mesquita,E.F.M.; Mello,S.C.R.P.; Hipolito,M.
ABSTRACT Ascites is a pathology characterized by the extravasation of fluid from blood vessels and its accumulation in the abdominal cavity, caused by several associated factors. In this paper, we report the occurrence of this syndrome in breeding male and female Bullfrogs fed a commercial fish feed with 40% crude protein. Liver malformation was already observed due to lack of protein deposition in adult animals from the same spawning. The culture of ascitic fluid showed absence of bacterial growth. Kidney histopathology showed, in both sexes, a large number of tubular structures with strongly eosinophilic hyaline material suggesting colloid growth in both the cortical region and spinal cord. The analysis also revealed granulomas in various stages of...

Breeding system and related floral features under natural and experimental conditions of Passiflora suberosa (Passifloraceae)
Provedor de dados: 51
Autores: Amela García,María Teresa.
The breeding system, the floral characteristics and the visitors of the polymorphic Passiflora suberosa were studied in different natural populations of Corrientes and Misiones provinces, and at a partially-opened greenhouse in Buenos Aires. The different reproductive indexes calculated evidenced that, although it is highly self-compatible, autogamy is partial. The reproductive efficiency was similar in the field and in the greenhouse. The major relative reproductive success obtained by induced self-pollination suggests that the reproductive output may be improved with the help of pollinations, either natural or artificial. Although the single flower and the blooming are inconspicuous, the floral characters may be involved in wasps attraction. The scarcity...

ABSTRACT Obtaining banana tetraploid cultivars from triploid strains results in total or partial reestablishment of fertility, allowing the occurrence of some fruits with seeds, a feature that is undesirable from a marketing perspective. The objective of this study was to assess the viability of pollen of 12 banana tetraploid hybrids (AAAB) by means of in vitro germination and two histochemical tests (acetocarmine and 2,3,5-triphenyltetrazolium chloride). The pollen tube growth was evaluated by germinating grains in three culture media — M1: 0.03% Ca(NO3)∙4H2O, 0.02% Mg(SO4)∙7H2O, 0.01% KNO3, 0.01% H3BO3 and 15% sucrose; M2: 0.03% Ca(NO3)∙4H2O, 0.01% KNO3, 0.01% H3BO3 and 10% sucrose; and M3: 0.015% H3BO3, 0.045% Ca3(PO4)2 and 25% sucrose.

ABSTRACT Different responses of two melon (Cucumis melo L.) genotypes (Şemame, drought and salt-tolerant and Ananas, drought and salt-sensitive) to drought stress with or without humic acid (HA) treatment were studied. The experiment was carried out under greenhouse conditions. The experimental design was two factorial randomized block with 4 replicates. HA treatment increased the shoot fresh and dry weights and leaf area of both genotypes under drought stress. HA stimulated accumulation of K and Ca ions, chlorophyll (SPAD value) and antioxidant enzyme activity (superoxide dismutase-SOD, catalase-CAT and glutathione reductase-GR) in both genotypes. This effect was more clear in the Şemame genotype than in Ananas.As a result, HA treatment has been proved to...

The aromatic and medicinal species Lippia alba is vigorous and rugged native to the South America (Atlantic Rainforest). Because it is an allogamous and self-incompatible species, natural populations have high morphological and chemical variability. This work had as objective to conduct a preliminary screening to identify new promising clones from a novel (recombinant) base population of Lippia alba with regard to its agronomic and phytochemical traits, using the linalool oil or chemotype as model. The two superior linalool clones, obtained by collection, were used as controls.

ABSTRACT In Brazil, the thrips (Enneothrips flavens Moulton) and rednecked peanutworm (Stegasta bosquella Chambers) are considered key pests for the peanut crop. Wild species show resistance to both of these pests, and can be used in breeding programs. The production of the sterile interspecific hybrids is necessary, which could be colchicine treated to get a synthetic amphidiploid with the same or similar genomic configuration of cultivated peanut. In this context, this study proposed the hybridization of wild pest-resistant species in 18 distinct combinations, obtaining the interspecific hybrids of Arachis and completing their characterization by (i) the reproductive characterization through pollen stainability with 2% acetocarmine (AC) solution with...

ABSTRACT Grain shape in rice is a key determinant of grain appearance, yield and market value, and thus has been widely studied. Rice mutant lines with long-grain phenotypes were previously isolated from an M2 population derived from mutagenized mature pollen grains that were treated with gamma-ray irradiation for a cultivar Ma85. To understand the genetic basis underlying the long-grain trait, two mutant lines, JF171 and JF178, were crossed with the short-grain parents JF222 and Samba, generating three F2 populations. Molecular marker-based genetic analysis was employed to detect the major QTLs that affected grain length, grain width, length-to-width ratio and grain weight. Based on the data obtained for the three populations, a joint major QTL for grain...

The aim of this study was to identify plants of the IAPAR-59 and Tupi IAC 1669-33 coffee cultivars with less defeated resistance genes by the rust races present at IAPAR (Londrina, Paraná State, Brazil) using test-crosses. Eighteen test-crosses derived from hybridizations between 'IAPAR-59' or 'Tupi IAC 1669-33' with susceptible coffee to the rust disease were evaluated. Six hybrids were used as susceptible standards originated from hybridizations between two susceptible coffee plants. Many parental plants of the 'IAPAR-59' and 'Tupi IAC 1669-33' presented more defeated resistance genes against rust races present at IAPAR than others of these cultivars or the genes were in heterozygous, because of segregant susceptible plants observed in some test-crosses....

Seed yield (PG), one-hundred seed weight (PCS), number of pods per plant (NV), weight of aerial part of the plant (PPA), harvest index (IC) and number of seeds per pod (NGV) were evaluated. Positive values of heterosis were detected for all traits. Estimates of heterosis components were significative for most traits, showing effects of aditivity and dominance. The specific heterosis was more important than the variety heterosis, mainly in the locality Anhembi. MTBR-95-123800 presented the best potential per se and as parent in crosses, but...

Evaluation of the average performance of topcrosses among food and grain type soybean
Provedor de dados: 52
Autores: Yokomizo,Gilberto K.; Vello,Natal A.
The food type soybean (exotic) are, in general, non-adapted to the Brazilian growing conditions. A breeding strategy to develop adapted food type soybean should involve crossing exotic with the available grain type genotypes. We evaluated the performance of topcrosses among food type and grain type soybeans. Best progenies showed different performance rates in each environment and they were not always the same in the different environments and joint analysis of lodging (L), plant height at maturity (PHM) and agronomic value (AV) was essential to avoid selection of plants with good performance for one trait and bad for another.) Piracicaba autumn environment (PA) caused low individual plant yield performance (IPY), and consequently, cultivation was not...

Autores: Barelli,Marco Antônio Aparecido; Gonçalves-Vidigal,Maria Celeste; Amaral Júnior,Antonio Teixeira do; Vidigal Filho,Pedro Soares; Scapim,Carlos Alberto.
Six common bean cultivars (LPSPI 93-17, LPSPI 93-19, FT-Nobre, Aporé, Rudá and Campeão-1) and their 15 diallel hybrids were evaluated for four agronomic characteristics using Griffing's methodology (1956). The analysis indicated the predominance of non-additive gene effects for days to germination and plant height. The mean number of days to flowering and mean height of the first pod insertion were predominantly controlled by genes showing additive effects. The results showed that LPSI 93-19 and Aporé were indicated for intra-population breeding, while the combinations LPSPI 93-17 x FT-Nobre, LPSPI 93-17 x Aporé, LPSPI 93-17 x Rudá, LPSPI 93-19 x Campeão-1, FT-Nobre x Aporé and Rudá x Campeão-1 were indicated for interpopulational breeding.

The aim of this study was to evaluate the resistance to fruit necrosis associated to Colletotrichum spp. in Coffea arabica L.. Twenty-two arabic coffee genotypes were performed in a randomized block design, with three replications and ten plants per plot. They were evaluated for the variables fruit necrosis, luminosity index inside of the plant canopy and fruits per productive nodes of the plants. There was genetic variability for the resistance to fruit necrosis. Different partial resistance levels, varying from highly susceptible (score = 3.89) to moderately resistant (score = 1.77) were observed. The genotypes that presented moderate resistance were the cultivars IPR-100, IPR-103, IPR-105 and IPR-108 and the coffee selection IAPAR-00023.

Preliminar evaluation of performance in topcrosses between vegetable type and grain type soybean
Provedor de dados: 52
Autores: Yokomizo,Gilberto K.; Vello,Natal A.; Nekastchalow,Marcos C.
Studies were conducted to evaluate the performance of topcrosses between food type soybean (with tendency to low physiological quality of the seeds) with two adapted grain type, seeking to associate adequate human food characteristics with adaptability. The conclusions were: a) The best topcrosses for vegetable type soybean were obtained predominantly with ´FT-2` and for seed yield with ´Doko`; b) The evaluated topcrosses presented high sensibility to winter conditions in comparison to summer, consequently the selection process in the winter it must be avoided; c) The selection for food type soybean it must be established in adequate values between individual plant yield and one hundred seed weight.

Autores: Silva,Celice Alexandre; Oliva,Marco Antonio; Vieira,Milene Faria; Fernandes,Geraldo Wilson.
Trioecy, the co-occurrence of the males, females, and hermaphrodite morphs in natural populations, is a rare and poorly studied breeding system. It is expressed in Coccoloba cereifera, an endemic, and endangered species from the rupestrian fields of Serra do Cipó, southeastern Brazil. Male individuals produce staminate flowers but no fruits. Female individuals produce pistillate flowers and set fruits. Both staminate and pistillate flowers present non-functional organs of the opposite sex that simulate perfect flowers. Hermaphrodite individuals produce two different perfect flowers, each one belonging to distinct individuals, and set fruits. Perfect flowers differ in the amount of pollen produced, in pollen viability, and in some morphological traits. Two...

The aim of this work was to evaluate the resistance to rust in coffee carrying S H3 gene and other S H genes. Twenty one CIFC’s coffee trees with several resistance genes S H were evaluated in field conditions. All the evaluated coffees carrying Sh3 gene presented resistance to the rust. It was possible that rust races with the virulence gene v3 in the Paraná State didn’t exist. The S H3 gene in combination with genes S H5, S H6, S H7, S H8, S H9 and S H? would be very important to obtain cultivars with more durable resistance to the rust.

SNPs genotyping technologies and their applications in farm animals breeding programs: review
Provedor de dados: 52
Autores: Koopaee,Hamed Kharrati; Koshkoiyeh,Ali Esmailizadeh.
Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide: adenine (A), thymine (T), cytosine (C) or guanine (G) in the genome sequence is altered. Traditional and high throughput methods are two main strategies for SNPs genotyping. The SNPs genotyping technologies provide powerful resources for animal breeding programs.Genomic selection using SNPs is a new tool for choosing the best breeding animals. In addition, the high density maps using SNPs can provide useful genetic tools to study quantitative traits genetic variations. There are many sources of SNPs and exhaustive numbers of methods of SNP detection to be considered. For many traits in farm animals, the rate of genetic improvement can be nearly doubled...

Bioreactors in coffee micropropagation
Provedor de dados: 61
Autores: Etienne,Hervé; Dechamp,E; Barry-Etienne,D; Bertrand,Bernóit.
In coffee, bioreactors are the most promising way for scaling-up micropropagation processes, particularly somatic embryogenesis. The availability of an efficient somatic embryogenesis process would allow the rapid mass production of heterozygous materials such as selected Coffea canephora clones and F1 Arabica hybrid varieties. For the last fifteen years, bioreactors (mechanically or pneumatically agitated bioreactors, temporary immersion bioreactors) have mostly been used on coffee to optimize the mass regeneration of somatic embryos from embryogenic tissues. This review presents the main results, obtained with several bioreactor models, concerning the different steps of the micropropagation process : i) the multiplication of embryogenic tissues, ii) the...

Autores: Silva,Maria do Céu; Várzea,Victor; Guerra-Guimarães,Leonor; Azinheira,Helena Gil; Fernandez,Diana; Petitot,Anne-Sophie; Bertrand,Benoit; Lashermes,Philippe; Nicole,Michel.
Considerable success has been obtained in the use of classical breeding to control economically important plant diseases, such as the coffee leaf rust and the coffee berry disease (CBD). There is a strong consensus that growing genetically resistant varieties is the most appropriate cost effective means of managing plant diseases and is one of the key components of crop improvement. It has also been recognized that a better knowledge of both, the pathogens and the plant defence mechanisms will allow the development of novel approaches to enhance the durability of resistance. After a brief description of concepts in the field of plant disease resistance, we attempt to give a view of the research progress on coffee leaf rust and CBD concerned with the...

Provedor de dados: 118
Autores: Mora,Freddy; Saavedra,Javier.
Flowering traits are becoming important breeding objectives in Eucalyptus cladocalyx. Previous studies have confirmed that the trees from Cowell, Australia, respond well for early flowering under the arid conditions in the Southern Atacama Desert, Chile. This selected population was evaluated for flowering intensity at the end of the flowering season of 2009/2010 (February 2010). A Bayesian threshold tree model via Gibbs sampling was used in the data analyses. The model included the genotype-environment interaction (two sites) using a bi-character threshold model. The posterior mean of the genetic correlation between the sites was positive and high (r=0.8) and, according to the 95% credible interval (0.44-0.96), it was significantly different from zero,...

Autores: Oliveira,Lucimar Rodrigues de; Miranda,Glauco Vieira; DeLima,Rodrigo Oliveira; Souza,Leandro Vagno de; Galvão,João Carlos Cardoso; Santos,Izabel Cristina dos.
The objectives were to identify maize germplasm for the organic productions system and to compare the genetic effects of the grain yield of maize cultivars in organic and conventional production systems. Diallel crosses were made between six maize cultivars and the hybrid combinations were evaluated in conventional and organic production systems. The hybrid combinations produced different grain yields in the two production systems. The interaction between general combining ability and production systems was significant for grain yield, ear height and number of ears. This indicates that the additive genetic effects differ in organic and conventional production systems. The specific combining abilities (SCA) were significant for grain yield and plant height,...

ABSTRACT: In order to assess the genetic control of resistance in the melon ‘Gaúcho Redondo’ to the root-knot nematode Meloidogyne incognita, an experiment was conducted in a randomized complete block design with three blocks and six treatments using the parental lines ‘Gaúcho Redondo’ (P1 resistant) and JAB 20 (P2 susceptible), as well as F1, F2, and backcross generations (RC1P1 and RC1P2). Seventy days after inoculation, individual plants were evaluated for resistance using the nematode reproduction factor (RF). The hypothesis of monogenic inheritance was rejected by the chi-square test (χ2), and results indicated that resistance is controlled by more than one gene locus, as confirmed by the quantitative analysis that revealed the presence of six genes.

Provedor de dados: 65
Autores: Ribeiro,Jeferson Corrêa; Silva,Luciano Pinheiro da; Caetano,Giovani da Costa; Crispim,Aline Camporez; Pacheco,Rodrigo de Oliveira; Torres,Robledo de Almeida.
ABSTRACT: Data from 629 meat type quails were used to study association between two different sets of traits: egg production and reproduction. Traits related to reproduction were: body weight at 42 days (W42), average egg weight (AEW), age at sexual maturity (ASM); and production traits: number of eggs produced from 42 until 182th day considering intervals of 35 days each period (P1, P2, P3 and P4). Canonical correlations were used to describe the association between these two sets of traits. The canonical coefficients indicated that egg production and reproductive traits were moderately related (0.3475). The first partial period of production (P1) and age at sexual maturity were the most relevant traits among the analyzed variables. Results show that...

Autores: Laviola,Bruno Galvêas; Alves,Alexandre Alonso; Gurgel,Fábio de Lima; Rosado,Tatiana Barbosa; Costa,Rhayanne Dias; Rocha,Rodrigo Barros.
An initial evaluation of early selection of physic nut genotypes based on phenotypic data is presented. In order to predict the genetic gains with early selection, genetic parameters, e.g. additive genetic variance, were first obtained for grain yield along with other numerous traits. The results demonstrated that additive genetic variance exists not only for grain yield, which is considered to be the most important trait for oil and biodiesel production, but also for numerous other traits. The predicted genetic gains for grain yield, considering the selection of the 30, 20, 10 and 5 best families in the second crop year are respectively, 40.47, 48.43, 61.78 and 70.28%.

ABSTRACT The slow darkening of grains is sought by bean breeders because the consumers consider that darker grains demand more time for cooking. The analysis currently used takes around 90 days to differentiate grain color among genotypes. The objective was to evaluate the color as a function of the value of L* (lightness) of carioca beans, by natural and accelerated methods to verify equivalence between methods, validation of the methodology and identification of genotypes tolerant to the darkening. The grain darkening was compared and evaluated by natural darkening method under shelf conditions, in days storage, and accelerated darkening method under ultraviolet light, in hours. The natural darkening time of 90 days was statistically equal to 24 hours of...

ABSTRACT In Brazil, as the soybean crop expands the losses caused by nematodes as well as its incidence in producing areas have increased. Therefore, this work aimed to develop a non-genetically modified soybean which combines desirable traits as the root-knot nematode resistance, early-maturity, high seed yielding, and high oil and protein contents. Consequently, seeds (F2) derived from the double-crossing between (Guarani x Sambaiba) x (M Soy 6101 x Conquista) were bulked to grow the F3 generation. Following generations were advanced by the SSD method of breeding until F6. Thus, plants showing superior characteristics were planted separately to perform progeny tests and then advanced breeding lines were thoroughly tested and compared to standards in...

Worldwide, the number of genebanks and the amount of seed stored in them has increased substantially over the past few decades. Most attention is focused on the likely benefits from conservation, but conserving germplasm involves costs whose nature and magnitude are largely unknown. Because more resources spent on conserving germplasm often means less spent on characterizing the collection or using the saved seeds in crop-improvement research, knowledge of the costs of germplasm conservation has important, possibly long run, R&amp;D management, policy, and food-security consequences. Moreover, these costs place a lower bound on the benefits deemed likely to justify the expense of saving this seed. In this paper we compile and use a set of cost data for...

The strawberry is an important agricultural crop in Brazil. However, most of the commercial genotypes currently in cultivation in Brazil were developed in other countries with environmental adaptations often inadequate for the regional conditions. In this work, inter-simple sequence repeat markers were used to determine the genetic variability and the loci segregation profiles of 84 strawberry hybrids obtained from a genetic breeding program at the ‘Empresa de Pesquisa Agropecuária de Minas Gerais.’ The hybrids were produced from crosses involving the following progenitors: ‘Toyonoka’ x ‘Sweet Charlie’, ‘Camino Real’ x ‘Sweet Charlie’, ‘Oso Grande’ x ‘Sweet Charlie’, ‘Oso Grande’ x ‘Toyonoka’, ‘Dover’ x ‘Oso Grande’, and ‘Camino Real’ x ‘Toyonoka’....

The aim of this study was to investigate the reproductive biology of Bowdichia virgilioides in an area of Cerrado (Brazilian Savanna). The study was carried out in Chapadinha, State of Maranhão in northeastern Brazil. Bowdichia virgilioides has cornucopia flowering and annual pattern. Flowering occurred at the beginning of the dry season, between June and August; and fruiting in the middle of this season, between July and October. The anthesis of B. virgilioides is diurnal, and the main flower resource is the nectar. During the flower opening, the anthers becomes dehiscent and thus pollen grains are deposited at the stigma, promoting automatic self-pollination. The species is self-compatible and apomitic. In the study area, they were visited by nine...

Panicum maximum Jacq. is one of the most cultivated grasses in the world. The intraspecific hybridization breeding program underway at Embrapa Beef Cattle aims at combining several agronomic characteristics in a single plant with high seed production. Four intraspecific hybrids originated from the cross between sexual tetraploid female plants with apomictic tetraploid male plants, including the genitors, were cytologically evaluated in the meiotic process throughout conventional methodology. Hybrids and genitors showed high meiotic stability. The percentage of abnormal cells among them ranged from 6.7 to 14.2%. Abnormalities recorded were irregular chromosome segregation, chromosome stickiness, and absence of the first cytokinesis, but the latter did not...

Twelve corn hybrids recommended for cropping in the south-central region of the Paraná State and 66 crossings obtained among these hybrids were evaluated for agronomic and morphological traits. These genotypes were evaluated in three experiments performed in Laranjeiras do Sul, Guarapuava and Cantagalo, Paraná State, Brazil. Heterosis and specific combining ability (SCA) were estimated for yield of husked ears. Data from measuring 22 morphological/agronomical traits of the parents were subjected to a multivariate joint analysis of variance and cluster analysis to group the parental hybrids via the neighbor method, using the generalized Mahalanobis distance. Pearson correlation coefficients between heterosis, SCA, D2 and yield of husked ears were obtained....

Discontinuous structure in landscapes may result in discontinuous, aggregated species body-mass patterns, reflecting the scales of structure available to animal communities within a landscape. The edges of these body-mass aggregations reflect transitions between available scales of landscape structure. Such transitions, or scale breaks, are theoretically associated with increased biological variability. We hypothesized that variability in population abundance is greater in animal species near the edge of body-mass aggregations than it is in species that are situated in the interior of body-mass aggregations. We tested this hypothesis by examining both temporal and spatial variability in the abundance of species in the bird community of the Florida...

The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach
Provedor de dados: 67
Autores: Paiaro,Valeria; Cocucci,Andrea A; Oliva,Gabriel E; Sérsic,Alicia N.
The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe. The identity of its floral visitor assemblage and to what extent this species depends on bird pollination for sexual reproduction is yet unknown. A. desideratum's vast distribution includes climatic gradients, which may promote geographical shifts in its floral visitors. The aims of this study were to determine the species dependence on pollinators to set fruits, to identify its floral visitor assemblages, to document possible geographical and environmental variation of these assemblages across the species range and to assess their temporal constancy. We conducted different pollination treatments in several...

Autores: Frixione,Martín G.
We describe the distribution and breeding abundance of the Imperial Shag (Phalacrocorax atriceps) in the northern portion of the Nahuel Huapi Lake (northwestern Patagonia, Argentina) during the 2006-2007 and 2007-2008 reproductive seasons. We recorded low population numbers and null breeding success in both seasons. Attacks from several scavenging birds were recorded, and breeding activities were interrupted abruptly. Future studies should consider the potential threats from scavenging birds, subsidized by urban garbage dumps, over this freshwater shag.

Over the last 20 years, the two uniparentally inherited marker systems, namely mitochondrial DNA and Y chromosome have been widely employed to solve questions about origin and prehistorical range expansions, demographic processes, both in humans and domestic animals. The mtDNA and the Y chromosome, with their unique patterns of inheritance, continue to be extremely important source of information. These markers played significant roles in farm animals in the evaluation of the genetic variation within- and among-breed strains and lines and have widely applied in the fields of linkage mapping, paternity tests, prediction of breeding values in genome-assisted selection, analysis of genetic diversity within breeds detection of population admixture, assessment...

Autores: Pereira,Arione S; Silva,Giovani O; Carvalho,Agnaldo DF; Ponijaleki,Rubens S.
ABSTRACT The aim of this work was to evaluate the performance of advanced potato clones for plant vigor, tuber yield components and specific gravity. Two sets of advanced clones and two control cultivars broadly grown in Brazil were compared. The first set, formed by 11 clones, was evaluated in the spring season of 2010, and the second, constituted by six clones, in the autumn season of 2011, in Canoinhas, Santa Catarina State, Brazil. The design of both experiments was a randomized complete block with four replications of two rows of 10 plants each. Plant vigor, tuber yield components and specific gravity were evaluated. The data of each experiment were submitted to analysis of variance and grouping means. Plant vigor was highly influenced by the...

Provedor de dados: 75
Autores: Bento,Cíntia dos S; Rodrigues,Rosana; Zerbini Júnior,Francisco Murilo; Sudré,Cláudia P.
The Pepper yellow mosaic virus (PepYMV) naturally infects chili and sweet pepper, as well as tomato plants in Brazil, leading to severe losses. This work reports the reaction to the PepYMV of 127 Capsicum spp. accessions, aiming at identifying resistance sources useful in breeding programs. The experiment was carried out in a completely randomized design, with eight replications, in greenhouse conditions. Plants were protected with an insect-proof screen to avoid virus dissemination by aphids. Leaves of Nicotiana debneyi infected with the PepYMV were used as the inoculum source. Plants were inoculated with three to four fully expanded leaves. A second inoculation was done 48 hours later to avoid escapes. Only the youngest fully expanded leaf was...

Autores: Riva-Souza,Elaine M; Rodrigues,Rosana; Sudré,Cláudia P; Pereira,Messias G; Viana,Alexandre P; Amaral Júnior,Antônio T do.
The economic importance of sweet pepper is rising in Brazil and abroad. Nevertheless, diseases, such as the bacterial spot (Xanthomonas campestris pv. vesicatoria or Xanthomonas euvesicatoria) jeopardize its yield. An efficient method for controlling the disease is the use of resistant varieties. The objective of this work was to select sweet pepper genotypes with resistance to the bacterial spot on a segregating population (Capsicum annum accessions UENF 1421, susceptible, x UENF 1381, resistant), advanced using the pedigree method. Three selection procedures, " selection between and within families" , " mass selection" , and " combined selection" were compared. Fifty-six F2:3 families (40 plants per family) were planted in the field, without replication....

The Capsicum breeding has been developed with emphasis in bell pepper (Capsicum annuum) and few studies are available in other species, especially C. baccatum, which has potential use not only as disease resistance source but also in obtaining new genotypes suitable for farmers' production. In the present work, the combining ability of ten C. baccatum hybrids, along with their five parentals, were tested considering 12 agronomic traits. The hybrids were produced from a complete diallel without reciprocals and assessed in greenhouse conditions, in Campos dos Goytacazes, Rio de Janeiro state, Brazil, during the period July to December 2009. The experimental design was a randomized block with three replications and the following agronomic traits evaluated:...

ABSTRACT: Mango (Mangifera indica L.) is one of the most important tropical fruits cultivated in Brazil with area higer than 70 thousand hectares, production of 970 thousand tones. However, it was exported only 13,4% of this production, which is equivalent to 130 thousand tones, in 2003. Mango production and exportation are mostly developed at tropical Semi-arid condition in Northeast Brazil, which concentrated 80% on a cultivar only, Tommy Atkins. This is very dangerous though if a severe disease occrus at this specific genotype, mango production may have a strong loss and, or the whole Brazilian mango area might be destroyed. This cultivar has some negative characteristics, such as high susceptibility to mango malformation and pulp breakdown as well as...

RESUMO: A cultura do abacate (Persea americana Mill), no Bioma Cerrado, apresenta grandes possibilidades uma vez que as condições ecológicas favorecem seu desenvolvimento. É grande a carência de informações sobre o comportamento dessa fruteira na região, no entanto, são encontradas plantas vegetando muito bem, sendo a maioria desse material originário de pés-francos, ou seja, não reproduzem as características das cultivares. A introdução dos "acessos" permite a obtenção de cultivares adaptadas à região. O fato de serem poucas as cultivares exploradas na região, o período de comercialização do produto é muito estreito, todavia, o abacate permite a seleção de cultivares com vistas a escalonar a produção durante todo o ano.

Na região Meio-Norte do Brasil, o milho tem se destacado em área cultivada entre as culturas produtoras de grãos de ciclo anual. A área colhida na safra 2013/2014 foi 1.011.400 hectares, sendo 405,0 mil no Estado do Piauí e 606,4 mil no Estado do Maranhão, com rendimento médio de grãos de 2.694 kg ha-1. O rendimento médio de grãos da região está muito aquém do potencial produtivo da espécie, que pode ser melhor explorada mediante a adoção das técnicas preconizadas que, muitas vezes, implicam em simples alterações nos sistemas de produção praticados, como exemplo a utilização de cultivares melhoradas. Este documento contém informações sobre cultivares de milho relacionadas à safra 2013/2014 que certamente contribuirão para o aumento do conhecimento da...

Autores: GONÇALVES, P. de S.; PAIVA, J. R. de; SOUZA R. A. de.
As pesquisas de melhoramento genetico no Brasil orientam-se principalmente no sentido de criacao de clones tolerantes a doencas e que, ao mesmo tempo, apresentem producao satisfatoria de latex. Todo o esforco da pesquisa nesse sentido ja reune atualmente um substancial acervo historico de informacoes, que, pela propria natureza da pesquisa, sempre tera a caracteristica de realimentador do processo de geracao de novos conhecimentos. Esse pressuposto e mais o proposito de situar o direcionamento atual das pesquisas de melhoramento genetico da seringueira no Brasil, consequencia naturalmente dos eventos historicos e sua evolucao, serviram de motivacao para os autores elaborarem este trabalho.

Avaliação de cultivares e seleções híbridas de manga em áreas de cerrado.
Provedor de dados: 14
Autores: PINTO, A. C. de Q.; VARGAS RAMOS, V. H.; DIAS, J. N.
RESUMO: A manga (Mangifera indica L. ) é uma das mais importantes frutas tropicais cultivada no Brasil com área de 70 mil hectares e produção equivalente a 970 mil toneladas. No entanto, a exportação de frutas frescas representou apenas 13,4% da produção, equivalente a 130 mil toneladas, em 2003. A área de produção para exportação está quase totalmente instalada no Nordeste brasileiro e 80% está concentrada na cultivar Tommy Atkins. Essa concentração é muito perigosa, uma vez que, com o advento de qualquer doença ou praga específica sobre essa cultivar, pode causar perdas enormes na produção, e a área de manga poderá ser completamente destruída. Essa cultivar apresenta algumas características negativas, tais como: suscetibilidade à malformação floral e ao...

Autores: CARGNIN, A.; ALBRECHT, J. C.; SOUZA, M. A. de; FRONZA, V.
RESUMO: O trabalho teve por objetivo avaliar o desempenho produtivo de genótipos de trigo irrigado nas condições de Cerrado de Minas Gerais. Os dados de produtividade de grãos utilizados para as análises foram obtidos a partir de ensaios de Valor de Cultivo e Uso, organizados pela Embrapa Cerrados. Os experimentos foram conduzidos em 21 ambientes, nos anos de 2002, 2003 e 2004, em diferentes locais do Estado de Minas Gerais. O delineamento experimental foi o de blocos ao acaso, com quatro repetições. O método do trapézio quadrático ponderado pelo CV, proposto por Carneiro (1998), destaca-se em razão da unicidade do parâmetro MAEC (medida de adaptabilidade e estabilidade de comportamento), que reúne os conceitos de adaptação, adaptabilidade e estabilidade....

Núcleo de conservação da raça Sindi no Semiárido.
Provedor de dados: 14
Autores: EMBRAPA SEMIÁRIDO.
A adaptação à diversidade de ambientes que há no país, resistência a doenças e boa conversão alimentar são qualidades que valorizam a pureza genética dos animais da raça Sindi conservados em área experimental da Embrapa Semiárido, em Petrolina-PE. A dupla aptidão, carne e leite, somada ao porte pequeno - adequado às regiões de poucos recursos alimentares, valorizam sua rusticidade em cruzamentos voltados à geração de animais mais resistentes às mudanças climáticas e do aquecimento global. Essas características atendem a demanda crescente dos criadores e contribuem para a inovação do agronegócio brasileiro. Em novembro de 2015, 45 fêmeas e um macho, receberam o Registro Genealógico como Puros de Origem (PO) pela Associação Brasileira dos Criadores de Zebu...

Desenvolvimento de cultivares do gênero Brachiaria (trin.) Griseb no Brasil.
Provedor de dados: 14
Autores: KARIA, C. T.; DUARTE, J. B.; ARAÚJO, A. C. G. de.
In Brazil, cultivated pastures cover more than 100 million hectares and Brachiaria species cover more than 45 million hectares. B. brizantha cv. Marandu and B. decumbens cv. Basilisk are the primary cultivars. The large areas occupied by the same cultivars pose a vulnerability to the beef cattle activity, and make clear how necessary is to increase the genetic diversity of forage cultivars. Most of Brachiaria species show the apomitic mode of reproduction, with seeds containing an embryo with assexual origin. The apomixis limits the use of the hybridization in the genetic breeding program. However, the induced duplication of the chromosomes of the sexual diploid B. ruziziensis, and the identification of sexual diploid B. brizantha and B. decumbens...

ABSTRACT: Domestic cattle breeds are classified in two subspecies: Bos taurus taurus, which have an european origin and Bos taurus indicus, the zebuines, originated in India. The main phenotypic difference between them is the presence of the hump, observed in the zebuines and absent in taurines. In addition, the sexual Y chromosome has been considered as a marker for these subspecies. Animals that have a submetacentric or metacêntrico Y chromosome are considered as Bos taurus taurus and those with acrocentric Y chromosome are typically zebuine animals (Bos taurus indicus). On the other hand it is known that the Y-chromosome possesses genes related to spermatogenesis and consequently to reproductive fitness. The objective of this review was the Y-chromosome...

Autores: BARIONI, L. G.; BELTRAME, R. T.; VELOSO, R. F.; SAUERESSIG, M. G.
This publication presents and evaluates two methods for ex-ante analysis of the optimum number of recipient females in embryo transfer programs. The first method is determinist, based on algebraic deduction, while the second is based on stochastic simulation using a Monte Carlo method for generating the number of embryos in each collection. The results show that the deterministic method sustainability overestimate the biologic efficiency of the embryo transfer program and underestimate, consequently, the cost per pregnancy (up to 9,1%). The superiority of the stochastic simulations was more pronounced when considering high variability in the number of embrios produced, reduced number of donnors ana low cost per recipient.

A Embrapa Gado de Leite e a Associação Brasileira dos Criadores de Girolando realizam anualmente avaliações genéticas de vacas e de touros, com dados obtidos do Programa de Melhoramento Genético da Raça Girolando (PMGG). Desde 2013 as avaliações genéticas das principais fêmeas Girolando passaram a ser divulgadas em Sumário de vacas, contendo as 1.000 vacas de maiores PTAs para a produção de leite. Dessa forma, os criadores terão conhecimento das vacas de maior potencial genético na população Girolando. Tal conhecimento certamente possibilitará selecionar, de modo mais eficiente, as vacas que poderão ser mães de touros e aquelas a serem submetidas a biotecnologias reprodutivas como a transferência de embriões (TE) e técnicas relacionadas, como a clonagem e...

Melhoramento da população de milho CMS 14.
Provedor de dados: 14
Autores: CAVALCANTE, E. da S.; ALBUQUERQUE, G. C. A.
A ausencia de sistemas de produção tecnificados, a não utilizacao de insumos modernos e, principalmente a não disponibilidade de sementes melhoradas, são fatores que concorrem de maneira decisiva para as baixas produtividades de milho no Amapá. As cultivares tradicionalmente plantadas como Pretinha e Palha Roxa não apresentaram rendimentos satisfatorios. Com o objetivo de se obter uma nova variedade de milho, a partir da população CMS 14 (Pool 25), a mais produtiva que a original, realizou-se nesta população o primeiro ciclo de seleção massal estratificada. Os trabalhos foram conduzidos no município de Mazagão, em solo Gley Pouco Humico hidromorfico.

Transporte rodoviário de bovinos de corte no Pantanal Sul-mato-grossense: ocorrência de lesões em carcaças.
Provedor de dados: 14
Autores: ANDRADE, E. N.; OJEDA FILHO, S.; SILVA, B. S. da; PALLA, M. H. de F.; SILVA, R. A. M. S.
Uma das etapas mais importantes no aproveitamento da carne no sistema de produção de gado de corte é o transporte até o abatedouro, sendo o transporte rodoviário o meio mais comum de condução de animais de corte para o abate (Tarrant et al., 1988). No Brasil, este transporte é realizado em "caminhões boiadeiros", tipo "truque" com a capacidade de carga média, de 20 animais (Joaquim, 2002). O transporte rodoviário realizado em condições desfavoráveis como aumento da temperatura, jejum, desidratação, cansaço pode provocar a morte dos animais ou conduzir a contusões, perda de peso e estresse dos animais (Knowles, 1999). No Pantanal Sul-Mato-Grossense a maioria dos bovinos é transportada por caminhões até os frigoríficos ou abatedouros. Este trabalho teve por...

Melhoramento vegetal e recursos genéticos forrageiros.
Provedor de dados: 14
Autores: ROCHA, J. E. da S.
A criação animal no Brasil é predominantemente extensiva em pastos cultivados ou nativos a depender da região. No semiárido a limitação de precipitação pluviométrica dificulta a manutenção de pastos cultivados, e a dependência pela vegetação nativa se torna maior. Embora exista inúmeras opções de gramíneas e leguminosas forrageiras que podem enriquecer a pastagem nativa, na região semiárida as opções disponíveis nos mercados formais são restritas e muitas vezes as sementes comercializadas não são validadas para a região. Para disponibilizar aos produtores forrageiras adaptadas às condições de manejo e clima, programas de melhoramento genético de forrageiras devem avaliar os acessos presentes em Banco Ativo de Germoplasma da Embrapa e de instituições...

Em 1986, foi iniciado um programa de coleta de germoplasma de guarana, visado a introducao de 1000 genotipos, no periodo de cinco anos. A coleta de estacas foi feita em plantas produtivas, resistentes a antracnose, superbrotamento. A baixa frequencia dessas plantas nas populacoes, da ordem de 10%, reduziu o numero de genotipos coletados. Entre 1986-1987, foram coletados 288 genotipos em 25 populacoes, plantados em 1987 e 1988, respectivamente, originando 187 clones.

Melhoramento genético animal.
Provedor de dados: 14
Autores: CARNEIRO JUNIOR, J. M.
O desempenho individual dos animais é resultado da ação conjunta do ambiente e da genética. Níveis elevados de produtividade e retorno econômico são alcançados pelo melhoramento concomitante das condições ambientais e da composição genética dos animais. Dentro do contexto de um mercado competitivo e globalizado, é necessário que os produtores se conscientizem de que ainda há muito que fazer no sentido de melhoramento ambiental, recuperação de pastagens, práticas básicas de manejo, controle zootécnico e financeiro de suas propriedades, o que permitirá e/ou facilitará a criação de programas de melhoramento genético. Paralelo a tudo isto, o melhoramento genético animal está diretamente relacionado com o aumento da produtividade e do retorno econômico da...
