Provedor de dados: 69
Autores: Tian,Yinshuai; Zhang,Min; Hu,Xiaole; Wang,Linghui; Dai,Jiao; Xu,Ying; Chen,Fang.
Background: Jatropha curcas L. (further referred to as Jatropha), as a rapidly emerging biofuel crop, has attracted worldwide interest. However, Jatropha is still an undomesticated plant, the true potential of this shrub has not yet been fully realized. To explore the potential of Jatropha, breeding and domestication are needed. Seed size is one of the most important traits of seed yield and has been selected since the beginning of agriculture. Increasing the seed size is a main goal of Jatropha domestication for increasing the seed yield, but the genetic regulation of seed size in Jatropha has not been fully understood. Results: We cloned CYP78A98 gene from Jatropha,a homologue of CYP78A5 in Arabidopsis.Wefound that CYP78A98 was highly expressed in male...

Autores: Coimbra,Ronaldo R.; Miranda,Glauco V.; Cruz,Cosme D.; Silva,Derly J.H.; Vilela,Ramiro A.
The aim of this study was to evaluate methods for developing a Brazilian maize core collection. For an initial survey of the active collection, passport information, as well as characterization and evaluation of accessions, were taken into consideration, these then being divided according to geographic region and kernel-type. Multiple sampling methods were evaluated. The strategy of constant sampling generated extensive alterations in extract accession frequency. The multivariate strategy with dispersion graphs and principal components associated with the Tocher method was considered efficient for identifying the most divergent genotypes. The multivariate strategy generated greater alterations in the variance of traits. The average number of traits...

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,...

Estimates of genetic parameters of wood traits for sawn timber production in Eucalyptus grandis
Provedor de dados: 74
Autores: Santos,Paulo Eduardo Telles dos; Geraldi,Isaias Olívio; Garcia,José Nivaldo.
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.

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...

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...

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...

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...

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...

Male-female interaction during breeding and non-breeding seasons in Akodon azarae (Rodentia, Muridae)
Provedor de dados: 76
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...

Breeding activity of Scinax centralis (Anura, Hylidae) in Central Brazil
Provedor de dados: 76
Autores: Alcantara,Mariana B.; Lima,Leôncio P.; Bastos,Rogério P.
From January, 1997 to April, 1998, we studied breeding activity in a population of Scinax centralis Pombal &amp;amp; Bastos, 1996, in the state of Goiás, inside the Cerrado Biome, Brazil. The behavior of males and females in the choruses, the relationships between environmental variables and the presence of individuals, the spatial distribution pattern, amplexus and clutches were analyzed. The breeding season occurred from November to May. The majority of males began to call when they entered the chorus; they were defending their calling sites against other males. We found a positive correlation between the number of females and males in the choruses, but no significant correlation was observed between the operational sexual ratio (OSR, number of...

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...

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...

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...

Apresenta-se neste trabalho um breve histórico dos registros genealógicos, com referencia a sua importância para o melhoramento genético animal. Ênfase especial e dada para o caso das raças zebuínas, criadas no Brasil. Em decorrência do fechamento do livro de registro; ocorrido em 1971 para a maioria das raças, e, em função de problemas conjunturais ocorridos desde então, e grande, atualmente, o contingente de animais que se encontra a margem do controle oficial. Por outro lado, os rebanhos considerados puros não conseguem suprir sequer a metade da demanda anual de reprodutores, necessária para a reposição nos planteis de seleção e nos rebanhos comerciais. Com base na analise e discussão de aspectos práticos, genéticos, econômicos e políticos, apresenta-se...

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,...

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...

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.

RESUMO: A seleção de porta-enxertos para nanismo tem sido um aspecto importante no programa de melhoramento de manga na região do Brasil Central. As cultivares de manga para exportação Tommy Atkins e Haden, embora produtivas, com frutas de coloração excelente e polpa sem fibras são vigorosas e de porte elevado, o que dificulta os tratos culturais e colheita. O objetivo deste trabalho foi estudar o efeito de copas e porta-enxertos no crescimento da planta, no rendimento e na qualidade dos frutos da manga. O experimento foi implantado em novembro de 1990 numa área de 4,0 ha. O delineamento experimental foi o de blocos ao acaso, em parcelas subdivididas, com três repetições, sendo avaliados oito porta-enxertos nas parcelas e quatro nas copas nas subparcelas....

Environmental characterisation to guide breeding decisions in a changing climate.
Provedor de dados: 14
Autores: RAMIREZ-VILLEGAS, J.; HEINEMANN, A. B.
Substantial evidence now exists suggesting that agricultural yields will have to increase significantly in order to meet food needs during the 21st century. One such way of increasing yields is to develop high yielding cultivars through crop improvement. This Working Paper summarises the results of a CCAFS project named Target Population of Environments (TPE). The project aimed at providing actionable information to crop breeders and, therefore, inform breeding decisions. We developed and applied a methodology for classifying crop growing environments, determining stress profiles and, finally, assessing the potential benefit of improved breeding practice. We present two contrasting case studies, one for upland rice in central Brazil and another for common...

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...

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...

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. L'étude de cette dernière et d'une Haplosporidie sp. trouvée chez des huîtres plates de Méditerranée a été réalisée en microscopie électronique. Les techniques d'isolement et de purification de Marteilia refringens ont été adaptées à d'autres Protozoaires. Des...

Genetics of European seabass (Dicentrarchus labrax L.)
Provedor de dados: 5
Autores: Chatain, Beatrice; Chavanne, Herve.
The production of sea bass, a major species in Mediterranean fish farming, still relies in many cases on the production of fingerlings issued from wild breeders. Still, genetic improvement is a major key to sustainable development for all optimized forms of animal production. Three types of genetic improvement can be acheived in fish: i) the production of monosex populations. For seabass, monosex female populations would be the objective as females grow 20-30% faster than males. However, sex determination in this species is complex, impacted by both genetic and environmental factors. Hence, production of monosex populations is not yet a routine operation, although in some cases almost 100% female batches have been obtained; ii) chromosome set...

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...

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...

Autores: Bouget, Jean-francois; Mazurie, Joseph.
This study presents the main results of oyster growth obtained experimentally in 2002 and 2003, in the farming area of Cancale before the leases reorganization of 2004. According to the REMORA monitoring network from 1990 to 2004, the oyster growth in Cancale bay may be characterized by an average annual weight gain (around 30g per year), a rather weak meat content compared to other regional oyster sites, and an exceptional quality of shell (absence of blisters, few Poly do rd). Spatially, the oyster farming area of Cancale shows rather homogeneous performances of breeding, in spite of the muddy southern area. In addition an experimental trial in 2003 allowed to evaluate favourably the potential of the new oyster area of Saint-Benoît : in these...

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...

Enzymatic polymorphism study as help for constitution of initial broodstock for a new cultivated finfish species.
Provedor de dados: 5
Autores: Renno, J; Luquet, P.
Leporinus friderici is a South American promising species for fish culture. In French Guiana the "morphological species", L. friderici, L. granti, L. lebaili and L. affinis steyermarki are found. Their identification is sometimes difficult on usual criterion. To constitute an initial broodstock of L. friderici from local wild populations, the genetic structure of these species was studied. Fifteen enzyme systems, representing twenty loci, were screened.

Autores: Campillo, Albert.
This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast.    Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations.   The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between...

Perspectives de développement de l'élevage de la palourde japonaise Ruditapes philippinarum dans le bassin ostréicole de Marennes-Oléron
Provedor de dados: 5
Autores: Goulletquer, Philippe; Nedhif, Mohamed; Heral, Maurice.
The complete Manila clam's breeding cycle (Ruditapes philippinarum ) in oysters ponds (claires) permits  to obtain a length of 25 mm after 1 year with a density range of 200 animals/m2 . As the primary production is restricted, the breeding biomass during the second year is limited to 500 g.m2 corresponding to a density between 30 to 50 clams..m-2. For an increase of the production it is necessary to extend the cultivated area to the tida1 bottom of the Bay of Marennes-Oleron. It appears that the man tidal level between + 2 and + 2.5 15 necessary with a density range of 200.m-2 to reach, the market size nine months later. The harvest sould be done before winter time to avoid a large 1055 of the flesh which can cause high levels of mortality.

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...

Autores: de la Barra,R; Latorre,E; Martínez,M. E; Calderón,C.
In this paper, the degree of differentiation and morphostructural variability reached by the type of animal resulting from sustained directional selection, in addition to its implications for the emergence of a new sheep breed are analyzed. Twenty-five rams and 200 ewes from a sheep flock submitted to directional selection since 1987 were measured. Thirteen body measurements were taken in other to evaluate the structural morphology and sexual dimorphism. These measurements were compared with identical measures taken in Australian Merino and Marin Magellan Meat Merino sheep breeds. The intrapopulation homogeneity was assessed using the coefficients of variation of the average percentage of body measurements. It is concluded that sustained directional...

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...

Morphology Differentiation and Structural Functionality of Ewes Due to Incomplete Crossbreeding
Provedor de dados: 77
Autores: Latorre,E; Uribe,H; Martínez,M. E; Calderón,C; de la Barra,R.
Most Chilean sheep stock comprises different degrees of crossbreeding over Corriedale breed. A common absorbent crossbreeding has been Australian Merino over Corriedale which, in many cases, has not been complete. The aim of this study was to evaluate the process of morphology differentiation and structural functionality of Corriedale ewes undergoing incomplete absorbent crossbreeding which was carried out in order to create an animal with a new morphology. A total of four hundred adult ewes were measured; two hundred belonging to the incomplete crossbreeding, and two hundred from the two original breeds (one hundred Corriedale and one hundred Australian Merino ewes). All measured ewes were randomly selected. Fourteen body measurements were recorded and...

Dawn chorus variation in East-Asian tropical montane forest birds and its ecological and morphological correlates
Provedor de dados: 16
Autores: Chen, W.-M.; Lee , Y.-F.; Tsai, C.-F.; Yao, C.-T.; Chen, Y.-H.; Li, S.-H.; Kuo, Y.-M.
Many birds in breeding seasons engage in vigorous dawn singing that often turns to a prominent chorus. We examined dawn chorus variation of avian assemblages in a tropical montane forest in Taiwan and tested the hypothesis that onset sequence is affected by eye sizes, foraging heights, and diet of birds. Chorus onset and duration varied between sampling months, but generally peaked in the prime breeding season. Overall dawn chorus length increased with, but mean duration per species was negatively correlated with, species richness. The inter-correlation among trait variables in phylogenetic independent contrasts was calculated and examined. Both foraging height and relative eye size were selected as positively explanatory factors, but no dietary effects...

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...

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....

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.

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...

Prüfung von Kartoffelsorten auf deren besondere Eignung für den ökologischen Landbau
Provedor de dados: 21
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.

'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...

Provedor de dados: 21
Autores: Hilbeck, Angelika; Weiss, Gabriele; Oehen, Bernadette; Römbke, Jörg; Jänsch, Stephan; Teichmann, Hanka; Lang, Andreas; Otto, Mathias; Tappeser, Beatrix.
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...

Autores: Shahid, Shaila; Md. Hossain, Zakir.
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...

Genetische Variation in der Resistenzinduktion gegenüber  Phytophthora infestans bei Tomaten
Provedor de dados: 21
Autores: Sharma, MSc Kalpana; Butz, Dipl. Ing. Andreas F.; Finckh, Prof. Maria R.
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...

Autores: Arncken, Christine.
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...

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.

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...

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.

Provedor de dados: 21
Autores: Klocke, Bettina; Flath, Kerstin; Schmitt, Anne-Kristin; Miedaner, Thomas; Schmiedchen, Brigitta; Spieß, Hartmut; Szabo, Lilla; Wilde, Peer.
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,...

Selektion auf Methioninreichtum des Samenproteins bei heimischen Leguminosen
Provedor de dados: 21
Autores: Schumacher, Henrik; Paulsen, Hans Marten; Gau, A. E.; Link, Wolfgang.
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.

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...

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...

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...

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...

Competitive oats for integrated weed management and organic rotations
Provedor de dados: 21
Autores: Fradgley, Nick.
Using a competitive crop like oats is essential for integrated management of weed problems.  Oats can compete well with weeds through efficient nutrient uptake, allelopathy and canopy cover shading.  Weeds are suppressed by the crops tillering ability and varieties with good canopy cover.  Some varieties can tolerate weeds better by having both good canopy cover and height.

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.

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...

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. Außerdem wurde daran gearbeitet,...

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.    Beim Vergleich über beide Jahre fanden wir inkonsistente Trends für 12 der erhobenen 26 Parameter: im einen Jahr waren die...

From Ideotype to Realtype concept: Dynamic management of plant breeding by a multidisciplinary and participatory way. Example of organic durum wheat
Provedor de dados: 21

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...

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...

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.

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...

Tomate en agriculture biologique : essai variétal sous tunnel froid : compte-rendu d'essai 2005
Provedor de dados: 21
Autores: Mazollier, Catherine; Picaut, Luc.
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.  En circuit court, les maraîchers ont une réflexion accrue sur la...

Erreichen ausreichender Homogenität durch Selektion samenfester Sorten am Beispiel Chinakohl
Provedor de dados: 21
Autores: Nagel-Heinze, Christine; Fleck, Michael.
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...

Improvement of seed quality of medicinal plants and herbs in organic farming
Provedor de dados: 21
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). In addition,...

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...

Autores: Bauer, Dietrich; Kern, Martin; Horneburg, Bernd; Fleck, Michael.
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. In Deutschland ist im herkömmlichen Saatguthandel fast nur noch die „Halblange Weiße“ erhältlich, in sehr unterschiedlichen Herkunftsqualitäten.

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...

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...

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.

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.

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...

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.

En agriculture, l'un des objectifs les plus importants pour la reproduction des végétaux cultivés connus pour leurs caractères exceptionnels (résistance aux maladies, meilleure productivité, haute teneur en matières nutritives, etc.) est le maintien de la conformité, aussi longtemps que possible, des générations descendantes vis-à-vis de la plante- mère dont elles sont issues. Dans le passé, cette manière de reproduire n'était possible que par les techniques de culture intervenant au niveau des organes végétatifs de la plante désirée (p. ex. le bouturage, le marcottage ou le greffage) que l'on appelle communément la multiplication par voie végétative. Cette voie de reproduction entraîne aussi des inconvénients:  - les risques de transmission des maladies...

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.

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...

Genetic resources of hulled wheat species in Czech organic farming
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek.
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...

Evolutionary plant breeding has a long history, but has so far not become part of mainstream breeding research, nor has it been implemented in practice to any substantial degree.   However, over the last decade, research in evolutionary plant breeding has markedly intensified. For example, there are currently  major research projects on-going in this area, including the EU funded project SOLIBAM, the Wheat Breeding LINK project in the UK, and the Danish Biobreed project. Also, a new 3-year international research project called COBRA on this topic is due to start in March 2013. Funded by the CORE Organic 2 Eranet the project brings together over 40 partner organizations from 18 European countries.   In addition, interest in evolutionary plant breeding is...

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.

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...

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.

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.

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.

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.

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.

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.

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,...

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...

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...

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...

N-uptake in winter wheat pure line varieties and winter wheat composite cross populations in the F11
Provedor de dados: 21
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...

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...

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...

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.

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.

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,...

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...

Dit rapport is van de Peenrassendemo 2009. Het is een vergelijking van de B-peenrassen voor de biologische teelt. In het project ‘Wie zaait zal oogsten’ is duidelijk geworden, dat een aantal belangrijke hoofdrassen van zaadbedrijven komen die niet biologische willen vermeerderen (o.a. Syngenta). Dit vormt een knelpunt voor voortgang van ontwikkeling richting annex.    De resultaten van deze rassendemo zijn tijdens een demomiddag besproken met de telers en de zaadfirma’s met het doel om te kijken of er op korte termijn een geschikt assortiment is te realiseren, of waar er nog specifieke eisen aan deze rassen ontbreken. Met de uitkomsten kunnen zaadbedrijven gerichter werken om een adequaat en sluitend assortiment met biologisch vermeerderde peenrassen te...

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.

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...

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....

Ökologisches Rebpflanzgut - Wege zur Erzeugung und Verbreitung

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. Das wenige Rebpflanzgut, das auf dem Markt vorhanden ist, deckt bei weitem nicht den Bedarf und ist vor allem meistens nicht in den gewünschten Sorten-Unterlagen Kombinationen vorhanden.

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.

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...

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...

Rothår og fosforopptak i korn
Provedor de dados: 21
Autores: Holten, Jon Magne; Løes, Anne-Kristin.
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...

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...

Ergebnisse aus den Mais Streifenversuchen 2017
Provedor de dados: 21
Autores: Klaiss, Matthias; Dierauer, Hansueli.
Mais wird züchterisch stark bearbeitet. Das Sortenspektrum im Biolandbau unterscheidet sich bisher nur wenig vom konventionellen. Die Hochleistungshybriden (Doppelhybriden) sind speziell für intensive Ackerbaustandorte gezüchtet und sind heute Standard. DSP hat nun einfachere Hybriden gezüchtet, die sich speziell für den Biolandbau eignen sollen. Die Getreidezüchtung Peter Kunz (GZPK) geht noch weiter. Sie haben mit OPM 12 seit 2011 eine offen abblühende Sorte im Angebot (Populationssorte) von der auch problemlos ein Nachbau möglich wäre. Diese wurde züchterisch durch positive Auslese verbessert und es steht jetzt die Nachfolge Sorte OPM13 zur Verfügung. Weder die Sorten von DSP noch die Sorten von GZPK sind auf der Liste der empfohlenen Sorten von...

Workshop: Züchtung für den Ökolandbau
Provedor de dados: 21
Autores: Steinberger, Josef.
Am 10. - 11. Juni 2002 fand beim Bundessortenamt in Hannover ein Workshop zum Thema "Züchtung für den Ökolandbau" statt.    Bei der Sortenwahl haben für den Ökolandbau die Konkurrenzkraft gegenüber Unkräutern, die Nährstoffeffizienz und die Toleranz gegenüber Krankheitsbefall eine weit größere Bedeutung als im konventionellen Landbau.    Die Krankheitstoleranz hat grundsätzlich sowohl für den Ökolandbau als auch für den konventionellen Landbau eine zunehmende Bedeutung. Die Gewichtung einzelner Krankheiten ist allerdings unterschiedlich, insbesondere aufgrund unterschiedlicher Fruchtfolgen und Bestandesdichten.    Die Notwendigkeit einer abiotischen Stresstoleranz der Sorten ist für den Ökolandbau höher als für den konventionellen Landbau. Allerdings...

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...

Erreichen ausreichender Homogenität durch Selektion samenfester Sorten am Beispiel Chinakohl
Provedor de dados: 21
Autores: Nagel-Heinze, Christine; Fleck, Michael.
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...

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...

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.

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...

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...

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...

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.

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...

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...

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...

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....

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.

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...

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...

Multilocal resistance assessment against common bunt of wheat (Triticum aestivum)
Provedor de dados: 21

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...

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...

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.

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...

An den Züchtungsstandorten des Vereins Kultursaat e.V. wurde die Methode der Geschmacksselektion entwickelt und für Pastinaken angewandt. Diese Methode hat sich bewährt und hat an einigen Sorten in einer Generation Geschmacksverbesserungen bewirkt. Dabei wurde mit Einzelpflanzennachkommenschaften von geschmacksselektierten Pastinaken gearbeitet. Die Methode der Geschmacksselektion ist relativ einfach und leicht...

GROWING MEDIA FOR ORGANIC TOMATO PLANTLET PRODUCTION
Provedor de dados: 21
Autores: Nielsen, Kai Lønne; Thorup-Kristensen, Kristian.
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...

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...

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...

In Central Europe low temperature is limiting soybean growth and biological nitrogen fixation (BNF). The BNF efficiency was shown to increase with bradyrhizobia strains selected for their cold tolerance. Significant bradyrhizobia x soybean variety interactions were reported. Co-inoculation with arbuscular mycorrhiza fungi (AMF) may promote bradyrhizobia and improve plant phosphorus uptake. The aim of this study is to identify (i) bradyrhizobia showing improved nodulation under cool conditions, (ii) bradyrhizobia x soybean variety and (iii) bradyrhizobia x AMF interactions. In 2011 twelve bradyrhizobia inoculants were tested with three soybean (Glycine max [L.]) varieties under three temperature regimes (14/10°C, 16/12°C, 22/20 °C) in a pot trial. In 2012...

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.

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,...

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...

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.

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.

Article of the month - The Yakutian cattle: a cow of the permafrost
Provedor de dados: 21
Autores: Kantanen, Juha.
Siberia's last remaining indigenous breed of domestic cattle, the Sakha Ynaga (in Yakutian language), or Yakutan Cattle, inhabit the lands surrounding the Lena River in Russia's remote Sakha Republic (Yakutia). A Finnish multidisciplinary team of researchers from MTT Agrifood Research Finland and the University of Helsinki's Aleksanteri Institute explored the genetic uniqueness of the Yakutian cattle and the effect of social and cultural factors on the survival of the breed through periods of major upheaval in Russia's history. The findings of this study have now been published in the book Sakha Ynaga - Cattle of the Yakuts.

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.

Sortenprüfung Biokartoffeln - Versuche 2017
Provedor de dados: 21
Autores: Dierauer, Hansueli; Schild, Marion; Gelencsér, Tobias.
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...

Generating and evaluating a novel genetic resource in wheat in diverse environments
Provedor de dados: 21
Autores: Wolfe, M; Snape, J.
The principal objective of the project is to develop composite cross populations of wheat based on a wide range of key parent varieties. 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...

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...

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...

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.

Usefulness of some winter wheat varieties for cultivation in organic farming
Provedor de dados: 21
Autores: Stalenga, Jarosław; Jończyk, Krzysztof.
Evaluation of the usefulness of six common winter wheat varieties (Kobra, Roma, Korweta, Sukces, Zyta, Mewa)  and one variety (Schwabenkorn) of spelt winter wheat (Triticum spelta) for cultivation in organic farming was the aim of the research. The research was based on a special field experiment established in 1994 on a grey-brown podzolic soil in which different crop production systems (organic, integrated and conventional) are compared. The research was conducted between 2002 and 2004 on the field of winter wheat in the organic system. The following parameters were taken into account in the research: Leaf Area Index, nitrogen nutrient status and grain yield. Average grain yields of winter wheat independently of the year and variety amounted to 4.36...

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...

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...

Possible agents for organic seed treatment
Provedor de dados: 21
Autores: Radics, László; Ertsey, Anna.
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...

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....

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...

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.

Autores: Brumlop, Sarah; Reichenbecher, Wolfram; Tappeser, Beatrix; Finckh, Maria R.
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). In this paper we discuss both the potential of marker-assisted breeding strategies and the potential of...

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.

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.

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.

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.

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...

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.

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.

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...

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...

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...

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...

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....

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.

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...

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...

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...

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.

Research on soil microbial ecology is beginning to elucidate how and how much beneficial soil micro-organisms (i.e. plant-probiotics) contribute to plant integrity and plant environmental fitness. The differences so far highlighted among crop varieties show highly positive interactions with plant-probiotic microflora (PPM), and upgrade the role of soil PPM at the level of other essential factors for sustainable plant breeding. Current research efforts, aimed to rapidly achieve crop varieties fitting for low-input and organic production systems, finally take into account the capacity of each individual variety to efficiently exploit indigenous PPM.

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.

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...

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...

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).

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...

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

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...

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...

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...

Abstract Parque Estadual do Tainhas - PET (Tainhas State Park) is a protected area with significant extensions of natural grasslands located in highland grasslands of northeastern Rio Grande do Sul state, Brazil, and recognized as an Important Bird Area. Our aim was to record the bird species richness of PET with a greater sampling effort than previous studies at the site, including unpublished data such as occurrence status of most species and evidence of breeding of some of them in the park. We surveyed birds between 2012 and 2018 performing aleatory trails covering mainly the central portion of PET (1,500 ha). We also added records from published studies. We listed 208 species, of which 203 were recorded during our fieldwork (including 18 species of...

Abstract: The objective of this work was to obtain cowpea (Vigna unguiculata) progenies with compound inflorescences, short peduncles, early cycle, good plant architecture, and high-yielding potential. The initial genetic material consisted of 453 F2:3 progenies, selected from ten crosses and evaluated using Federer’s augmented block design, with two controls. Of these, 60 progenies from the F4:5 and F4:6 generations were selected and assessed in two consecutive experiments, both in a 8x8 lattice design with four controls and four replicates. Early selection was efficient at fixing the evaluated traits. A wide genetic variability was detected among and within progenies. The estimated and obtained heritability and genetic gains in the F4:5 and F4:6...

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...

Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing inaccessibility, and rising wood costs from natural forests due to new environmental restrictions related to logging. Forestry today is on the threshold of the widespread introduction of biotechnology into its operational practices. In many cases, the biotechnology likely to be introduced is simply an extension of that being utilized in agriculture, such as herbicide-tolerant genes. However, biotechnology in forestry also is developing applications unique to forestry,...

Overall, 2,713 producers with one or more beef cows participated in the NAHMS Beef '97 Study, representing 85.7 percent of the beef cows and 77.6 percent of the beef cow operations in the United States as of January 1997. Producers whose cow-calf herds were the primary source of family income were more productive than those whose herds were a supplemental source of income. Cow-calf herds were the primary source of income for 14 percent of the producers and provided supplemental income for 69 percent of the producers....

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...

Autores: Abele,   Steffen; Twine,   Edgar; Ntawuruhunga,   Pheneas; Baguma,   Yonah; Kanobe,   Charles; Bua,   Anthony.
The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

Autores: Chudleigh,   Peter D.
This study is an ex-post, economic assessment of two projects supported by ACIAR and concerned with the breeding and quality analysis of rapeseed in Australia and China. These projects were carried out sequentially with the first one commencing on 1 July 1986. The second one was completed on 30 June 1991. The projects were essentially an exchange of knowledge and germplasm of rape (Brassica napus) between plant breeders in Australia and China. The projects resulted in the release of varieties of rape that yielded improved seed in Australia, China and other developed and developing countries.  An economic evaluation of these projects was made in 1991 and the results published in Chudleigh (1991). Assumptions made in the 1991 analysis have now been updated....

Autores: Singh,   Rajinder Pal; Brennan,   John P.; Farrell,   Tim; Williams,   Robert L.; Rienke,   Russell; Lewin,   Laurie; Mullen,   John D.
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...

Abstract  Even though the peach tree was introduced in Brazil during the XVI century, it was only on the 1940’s that the first peach breeding program started in the country. Later on, other programs started being, until now, the largest ones, and the programs that gave more significant contributions to the peach crop development those from the Instituto Agronômico de Campinas and from Embrapa Temperate Agriculture. Presently, peach is cultivated not only in the colder areas of the South but also in the subtropics and high altitude areas of the tropics, due to dozens of cultivars released by these breeding programs. Peaches are sold entirely in the domestic market and in the largest consumers market, State of São Paulo, the preference is for white sweet...

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.

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,...

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. In 2002 a research line to...

Septoria leaf spot (Septoria lycopersici) is one of the major fungal diseases of tomatoes (Solanum lycopersicum) in tropical and subtropical regions with humid climates and/or in areas cultivated under sprinkler irrigation systems. Sources of resistance have been found in accessions of Solanum (section Lycopersicon) species. However, many of the described sources are not effective under Brazilian conditions. The objective of this work was to evaluate wild and cultivated Solanum (section Lycopersicon) germplasm to S. lycopersici isolates. A collection of 124 accessions was initially evaluated under greenhouse conditions. Ten accessions were highly resistance (HR), whereas 33 were classified as having a resistant (R) response to S. lycopersici isolates....

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. Number of leaves, length of the main stem, number...

Among the traits that may add commercial value to maize (Zea mays L.), those related to nutritional quality, specially protein and oil content, are of great interest to the feed industry. The objective of this work was studying the variability of protein and oil content, as well as yield, in a group of maize testcrosses. One hundred and twenty S1 families of the ESA23B maize population were crossed with two testers, an open-pollinated population (BR108) and an exotic line (CML269). Testcrosses were evaluated at two locations under a completely randomized block design with three replications. Ear and grain yield, protein and oil content were evaluated. The three-way interaction location x tester x progeny was significant for all traits, except for oil...

Selection for bulb maturity in onion
Provedor de dados: 63
Autores: Cardoso,Antonio Ismael Inácio; Costa,Cyro Paulino da.
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...

ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês locally adapted hair breeds and crosses between Dorper × Morada Nova and Dorper × Santa Inês slaughtered at approximately 35 kg. Morada Nova lambs showed lower (p &lt; 0.05) performance compared to the other genetic groups resulting in a higher age at slaughter (p &lt; 0.05). Crossbred Dorper × Santa Inês and Dorper × Morada Nova lambs showed better characteristics for meat production with better (p &lt;...

Meiotic behavior in apomictic Brachiaria ruziziensis × B. brizantha (Poaceae) progenies
Provedor de dados: 63
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...

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...

Lippia alba (Mill.) N.E.Br. is an aromatic and medicinal shrub native to the American continent. Despite its potential as a source of essential oil for the pharmaceutical and cosmetics industries, few selection and genetic improvement studies have been carried out. The aim of this study was to provide genetic information on this species for breeding programs, showing its selection potential, by investigating clonal half-sib progenies. The following characteristics were evaluated per plant: leaf dry mass (LDM), total dry mass (TDM), leaf yield (LY), essential oil yield (EOY) and oil production (OP). Estimates were made for the several genetic parameters including absolute genetic gain at 30% selection intensity, correlations and relative contribution of...

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...

Autores: Carmo,Cátia Dias do; Silva,Maiane Suzarte da; Oliveira,Gilmara Alvarenga Fachardo; Oliveira,Eder Jorge de.
The geminivirus complex known as cassava mosaic disease (CMD) is one of the most devastating viruses for cassava (Manihot esculenta Crantz). The aim of this study was to use molecular-assisted selection (MAS) to identify CMD-resistant accessions and ascertain promising crosses with elite Brazilian varieties. One thousand two hundred twenty-four accessions were genotyped using five molecular markers (NS169, NS158, SSRY028, SSRY040 and RME1) that were associated with resistance to CMD, along with 402 SNPs (single-nucleotide polymorphism). The promising crosses were identified using a discriminant analysis of main component (DAPC), and the matrix of genomic relationship was estimated with SNP markers. The CMD1 gene, previously described in M. glaziovii, was...

Objectives of this study were to estimate genetic parameters of number of born alive (NBA) in different parities and to examine the appropriateness of the 3 models. The genetic parameters in all models were evaluated. In model I, single-trait animal model, each parity was considered as a different trait. In model II, repeatability model, each trait of different paritys was measured repeatedly. In model I, multiple-trait model, each parity was treated as a different trait. The 6,375 records of NBA from sows that born between 2546 to 2552 were analysed. They were grew by private farms in the central part of Thailand. (Co)variance components and breeding value were estimated by Restricted Maximum Likelihood (REML) and Best Linear Unbiased Prediction (BLUP)...

Autores: Souza Júnior,Manoel T.; Nickel,Osmar; Gonsalves,Dennis.
Translatable and nontranslatable versions of the coat protein (cp) gene of a Papaya ringspot virus (PRSV) isolate collected in the state of Bahia, Brazil, were engineered for expression in Sunrise and Sunset Solo varieties of papaya (Carica papaya). The biolistic system was used to transform secondary somatic embryo cultures derived from immature zygotic embryos. Fifty-four transgenic lines, 26 translatable and 28 nontranslatable gene versions, were regenerated, with a transformation efficiency of 2.7%. Inoculation of cloned R0 plants with PRSV BR, PRSV HA or PRSV TH, Brazilian, Hawaiian and Thai isolates, respectively, revealed lines with mono-, double-, and triple-resistance. After molecular analysis and a preliminary agronomic evaluation, 13 R1 and R2...

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...

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 Repeatability allows an estimation of the number of evaluations needed to optimize the selection of superior genotypes, with consequent effects on the research costs in terms of financial and human resources. The objective of this study was to estimate the coefficient of repeatability of biometric and yield traits, related to fruits and seeds of sacha inchi (Plukenetia volubilis), and to define the number of evaluations required for an efficient selection and evaluation of genotypes of the species. A total of 37 non-domesticated accessions were evaluated for 19 months in a randomized block design with 5 replications and 2 plants per plot. The total number of fruits, total number of seeds, total fruit weight, mean fruit weight, and number of seeds...

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...

UNRAVELING THE MOLECULES HIDDEN IN THE GRAY SHADOWS OF QUANTITATIVE DISEASE RESISTANCE TO PATHOGENS
Provedor de dados: 37
Autores: VÁSQUEZ,Andrea Ximena; SOTO SEDANO,Johana Carolina; LÓPEZ CARRASCAL,Camilo Ernesto.
ABSTRACT One of the most challenging questions in plant breeding and molecular plant pathology research is what are the genetic and molecular bases of quantitative disease resistance (QDR)?. The scarce knowledge of how this type of resistance works has hindered plant breeders to fully take advantage of it. To overcome these obstacles new methodologies for the study of quantitative traits have been developed. Approaches such as genetic mapping, identification of quantitative trait loci (QTL) and association mapping, including candidate gene approach and genome wide association studies, have been historically undertaken to dissect quantitative traits and therefore to study QDR. Additionally, great advances in quantitative phenotypic data collection have been...

Com o advento da agricultura moderna, as sementes crioulas foram, em geral, substituídas por cultivares híbridos, com elevado potencial produtivo, porém mais dependentes de insumos e tecnologias intensivas. O objetivo deste trabalho foi avaliar variedades de milho crioulo, de forma a identificar materiais mais produtivos e que propiciem o processo sustentável no qual os próprios grãos possam ser utilizados como semente.

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...

Genetic variability for frost resistance among Coffea accessions assessed in the field and in a cold chamber
Provedor de dados: 52
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.

Provedor de dados: 52
Autores: Pereira,Fernanda Aparecida Castro; Vello,Natal Antonio; Rocha,Gabriela Antônia de Freitas; Nekatschalow,Marcos Custódio.
Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of parents was composed of ten experimental lines with high grain yield and the group II consisted in five genotypes with possible resistance to white mold. Ten plants of each cross in the F4 generation and the parents were evaluated for reaction to fungus infection using the method of inoculation in detached leaves in order to assess the severity of the disease and to later estimate the combining abilities. Estimates of the specific combining ability (SCA)...

Autores: Sera,Gustavo Hiroshi; Sera,Tumoru; Ito,Dhalton Shiguer; Azevedo,José Alves de; Mata,João Siqueira da; Dói,Deisy Saori; Ribeiro Filho,Claudionor; Kanayama,Fabio Seidi.
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.

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...

Utility of basic research in plant/crop physiology in relation to crop improvement: a review and a personal account
Provedor de dados: 61
Autores: El-Sharkawy,Mabrouk A.
Agricultural research and development plays an essential role in a nation's economic development, providing for food security for an ever-increasing population. In developed countries, the gap between potential and actual yield is largely closed because of a combination of advanced technologies, high-yielding new varieties and the application of agrochemicals in highly mechanized production systems. In most of these countries, agricultural production exceeds national demand, resulting in excess products for export. In many of the developing countries, however, agricultural productivity is still far below what it should be because of multiple technical and socio-economic constraints. Food deficits are the norm in poor and middle-income countries, requiring...

Provedor de dados: 65
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,...

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...

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...
