Manejo y conservación de germoplasma de la familia Caricaceae.
Provedor de dados: 32
Autores: Romero Rodríguez, Jorge Arturo.
Especies de la familia Caricaceae han encontrado condiciones favorables para desarrollar y diversificarse en México, cinco de los géneros que prosperan en América, cuentan con al menos una especie en el país y se considera que la especie más importante económicamente, Carica papaya L., tiene su centro de alta diversidad en el sureste del país, además de dos géneros endémicos que prosperan en regiones semiáridas y de bosque mesófilo. Sin embargo, la investigación que se realiza al respecto es limitada y buena parte de la información existente de la familia proviene de otras latitudes. Dada la responsabilidad del país de salvaguardar y dar uso eficiente a la diversidad de Carica papaya y demás integrantes de la familia Caricaceae, la presente investigación...

Autores: Peters, Michael; CIAT (International Center for Tropical Agriculture); m.peters-ciat@cgiar.org; Hyman, Glenn; CIAT (International Center for Tropical Agriculture); g.hyman@cgiar.org; Jones, Peter; CIAT (International Center for Tropical Agriculture); p.jones@cgiar.org.
This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. These are the introduction of mass reservoirs outside of the original areas of collection and conservation inside the area of origin. Four potential areas for in situ conservation in Latin America are identified. Although more detailed studies using remote sensing, soil information, and field reconnaissance will be necessary for a final assessment of the suggested areas as field conservation sites, we discuss the possibilities of establishing low-maintenance...

Plant prebiotics and human health: Biotechnology to breed prebiotic-rich nutritious food crops
Provedor de dados: 69
Autores: Dwivedi,Sangam; Sahrawat,Kanwar; Puppala,Naveen; Ortiz,Rodomiro.
Microbiota in the gut play essential roles in human health. Prebiotics are non-digestible complex carbohydrates that are fermented in the colon, yielding energy and short chain fatty acids, and selectively promote the growth of Bifidobacteria and Lactobacillae in the gastro-intestinal tract. Fructans and inulin are the best-characterized plant prebiotics. Many vegetable, root and tuber crops as well as some fruit crops are the best-known sources of prebiotic carbohydrates, while the prebiotic-rich grain crops include barley, chickpea, lentil, lupin, and wheat. Some prebiotic-rich crop germplasm have been reported in barley, chickpea, lentil, wheat, yacon, and Jerusalem artichoke. A few major quantitative trait loci and gene-based markers associated with...

The genetic diversity of Sardinian myrtle (Myrtus communis L.) populations
Provedor de dados: 69
Autores: Melito,Sara; Chessa,Innocenza; Erre,Patrizia; Podani,János; Mulas,Maurizio.
Background: The myrtle (Myrtus communis) is a common shrub widespread in the Mediterranean Basin. Its fruit and leaves exhibit antioxidant, antibacterial and antifungal properties, and are used for their content of essential oils and for their medicinal properties, but most commonly as an ingredient in locally made liquor. The uncontrolled exploitation of natural stands has reduced both the species' geographical coverage and the size of individual populations. The selection of genotypes for controlled cultivation requires a characterization of the genetic diversity present both within and between populations. Results: Genotypic variation was evaluated using ISSR profiling and genetic diversity characterized using standard population genetics approaches....

Provedor de dados: 74
Autores: Palmieri,Darío A.; Bechara,Marcelo D.; Curi,Rogério A.; Monteiro,Jomar P.; Valente,Sérgio E.S.; Gimenes,Marcos A.; Lopes,Catalina R.
Diversity in 26 microsatellite loci from section Caulorrhizae germplasm was evaluated by using 33 accessions of A. pintoi Krapov. &amp;amp; W.C. Gregory and ten accessions of Arachis repens Handro. Twenty loci proved to be polymorphic and a total of 196 alleles were detected with an average of 9.8 alleles per locus. The variability found in those loci was greater than the variability found using morphological characters, seed storage proteins and RAPD markers previously used in this germplasm. The high potential of these markers to detect species-specific alleles and discriminate among accessions was demonstrated. The set of microsatellite primer pairs developed by our group for A. pintoi are useful molecular tools for evaluating Section Caulorrhizae...

Provedor de dados: 74
Autores: Techio,Vânia Helena; Davide,Lisete Chamma; Pereira,Antônio Vander; Bearzoti,Eduardo.
Cytotaxonomic studies were carried out on 26 accessions of Pennisetum spp. originating from the Active Germplasm Bank of Embrapa Gado de Leite-Juiz de Fora, Minas Gerais, Brazil.This study presents cytogenetics and reproductive morphological data for each one of these accessions, which allowed groupings and suggest botanical identifications to be established. The metaphases of the accessions characterized as P. purpureum confirmed the presence of 2n = 28 chromosomes that have already been described for this species. For the hybrids between P. purpureum and P. glaucum and for the hexaploids, resulting from the chromosome duplication of these hybrids, 2n = 21 and 2n = 42 chromosomes were confirmed, respectively. The wild accession identified as P. setosum...

Mating system in a natural population of Theobroma grandiflorum (Willd. ex Spreng.) Schum., by microsatellite markers
Provedor de dados: 74
Autores: Alves,Rafael M.; Artero,Angela S.; Sebbenn,Alexandre M.; Figueira,Antonio.
The aim of this research was to study the mating system of a natural population of Theobroma grandiflorum (cupuassu) from Nova Ipixuna, Pará state, using microsatellite markers. Eight polymorphic microsatellite loci were analyzed in eight families, each represented by 10 six-month old seedlings derived from open-pollinated pods. The estimation for the multilocus outcrossing rate (&lt;img border=0 id="_x0000_i1026" src="../../img/revistas/gmb/v26n3/a25img01.gif" align=absmiddle&gt;m = 1.0) and individual outcrossing rate (&lt;img border=0 id="_x0000_i1027" src="../../img/revistas/gmb/v26n3/a25img01.gif" align=absmiddle&gt; = 1.0) for this population suggests that T. grandiflorum may be a perfect outbreeding (allogamous) species. Likewise, for the studied...

Provedor de dados: 74
Autores: Schuster,Ivan; Vieira,Elisa Serra Negra; Silva,Glacy Jaqueline da; Franco,Francisco de Assis; Marchioro,Volmir Sérgio.
Wheat (Triticum aestivum) is one of the most important food staples in the south of Brazil. Understanding genetic variability among the assortment of Brazilian wheat is important for breeding. The aim of this work was to molecularly characterize the thirty-six wheat cultivars recommended for various regions of Brazil, and to assess mutual genetic distances, through the use of microsatellite markers. Twenty three polymorphic microsatellite markers (PMM) delineated all 36 of the samples, revealing a total of 74 simple sequence repeat (SSR) alleles, i.e. an average of 3.2 alleles per locus. Polymorphic information content (PIC value) calculated to assess the informativeness of each marker ranged from 0.20 to 0.79, with a mean of 0.49. Genetic distances among...

Transferability and use of microsatellite markers for the genetic analysis of the germplasm of some Arachis section species of the genus Arachis
Provedor de dados: 74
Autores: Bravo,Juliana Pereira; Hoshino,Andrea Akemi; Angelici,Carla Maria Lara C.D.; Lopes,Catalina Romero; Gimenes,Marcos Aparecido.
The Arachis section is the most important of the nine sections of the genus Arachis because it includes the cultivated peanut, Arachis hypogaea. The genetic improvement of A. hypogaea using wild relatives is at an early stage of development in spite of their potential as sources of genes, including those for disease and pests resistance, that are not found in the A. hypogaea primary gene pool. Section Arachis species germplasm has been collected and maintained in gene banks and its use and effective conservation depends on our knowledge of the genetic variability contained in this material. Microsatellites are routinely used for the analysis of genetic variability because they are highly polymorphic and codominant. The objective of this study was to...

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...

Autores: Nunes,Raquel SC; Pinhati,Fernanda R; Golinelli,Luciana P; Rebouças,Tiyoko Nair H; Paschoalin,Vânia Margaret F; Silva,Joab T da.
Taro (Colocasia esculenta) is a tuberous plant belonging to the Araceae family whose tuber is the 14th most consumed food crop in the world. Characterized as an unconventional vegetable, taro is grown in Brazil as a subsistence crop, but in recent years began to gain commercial importance, especially in the states of Espirito Santo, Minas Gerais and Rio de Janeiro. To avoid loss of genetic diversity of the local varieties traditionally grown in Brazil a core collection for taro germplasm has been developed by the Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural do estado do Espirito Santo (Incaper). The aim of this study was to perform a molecular characterization of the seven regional core collections. Genetic diversity of the...

Provedor de dados: 75
Autores: Silva,Alysson J da; Oliveira,Gustavo HF de; Pastoriza,Rhuan JG; Maranhão,Eduardo HA; Pedrosa,Elvira MR; Maranhão,Sandra RVL; Boiteux,Leonardo S; Pinheiro,Jadir B; Carvalho Filho,José Luiz S de.
ABSTRACT Meloidogyne enterolobii (=M. mayaguensis) is an emerging plant pathogen capable of inducing root galls and yield reduction in a wide range of host species. This pathogen has also been reported as a global threat for tomato (Solanum lycopersicum) crop production mainly due to its ability to overcome the resistance meditated by the Mi-1 gene. Despite the potential importance of this nematode, sources of resistance to M. enterolobii are not yet available for breeding purposes. The main objective of the present work was to evaluate a large Solanum (section Lycopersicum) germplasm (comprising nine species and one botanic variety) aiming to identify useful sources of resistance to M. enterolobii. In the first screening assay, 101 accessions and the...

RESUMO: A cultura do abacate (Persea americana Mill), no Bioma Cerrado, apresenta grandes possibilidades uma vez que as condições ecológicas favorecem seu desenvolvimento. É grande a carência de informações sobre o comportamento dessa fruteira na região, no entanto, são encontradas plantas vegetando muito bem, sendo a maioria desse material originário de pés-francos, ou seja, não reproduzem as características das cultivares. A introdução dos "acessos" permite a obtenção de cultivares adaptadas à região. O fato de serem poucas as cultivares exploradas na região, o período de comercialização do produto é muito estreito, todavia, o abacate permite a seleção de cultivares com vistas a escalonar a produção durante todo o ano.

Provedor de dados: 14
Autores: VIEIRA, E. A.; FIALHO, J. de F.; SILVA, M. S.; FALEIRO, F. G.
RESUMO: Por reunirem constituições genéticas de diferentes origens e níveis de melhoramento, os bancos de germoplasma podem constituir-se em ótimas fontes de genes para programas de melhoramento. Para tanto, é fundamental que o melhorista conheça profundamente o germoplasma disponível em relação à variabilidade e ao seu desempenho agronômico. O objetivo deste estudo foi estimar a variabilidade genética de 356 acessos do banco de germoplasma de mandioca da Embrapa Cerrados em relação a 27 descritores morfológicos, estabelecer quais desses evidenciam maior entropia e agrupar os acessos em função da sua dissimilaridade genética. No ano de 2004, 356 acessos de mandioca foram caracterizados por meio de 27 descritores morfológicos. Com base nos dados aferidos,...

Ocorrência da mela do feijoeiro em germoplasmas de caupi no Acre.
Provedor de dados: 14
Autores: CARDOSO, J. E.; MESQUITA, J. E. de L.
A murcha da teia micélica ou mela do feijoeiro constitui-se no principal entrave agronômico na produção e produtividade do feijoeiro comum (Phaseolus vulgaris L.) no estado do Acre. Prevalecendo as condições de elevada umidade relativa do ar, precipitação e intensa nebulosidade, a ocorrência da enfermidade pode dizimar completamente um plantio de feijão susceptível em pouco tempo. Causada pelo fungo Thanatephorus cucumeris, a doença tem o seu controle bastante difícil, devido a grande quantidade de hospedeiros intermediários do fungo, bem como sua alta capacidade de permanecer saprofiticamente em restos culturais de solo. Como o caupi tem potencial mais do que suficiente de substituir o feijão-comum, sob a ótica de consumo e também de produção, trabalhos...

Resumo: A introdução de populações heterogêneas e a sua caracterização é o primeiro passo para um programa de seleção e/ou melhoramento genético de plantas. A heterogeneidade permite a seleção de indivíduos superiores que podem ser diretamente liberados como cultivares ou servir como fonte de genes em programas de melhoramento genético. A flora nativa da Região é extremamente rica em leguminosas, sendo, inclusive, centro de origem de diversas espécies que poderiam ser usadas como forrageiras. Dentre as leguminosas nativas, destaca-se o gênero Stylosanthes que possui diversas espécies, amplamente, distribuídas pelo continente americano, apresentando grande variação de formas e tipos, resultante da evolução de populações submetidas às diferentes condições de...

Autores: RODRIGUES, S. T.; MACEDO, E. G.; GOMES, J. I.
Estudos taxonômicos e/ou morfológicos com espécies oriundas de bancos de germoplasma são pouco realizados, apesar da importância deles para caracterização e domesticação. O objetivo deste estudo foi avaliar as características morfométricas de 23 acessos de Oenocarpus minor Martius e Oenocarpus mapora Karsten cultivados no referido banco de germoplasma. Órgãos vegetativos e reprodutivos desses acessos foram medidos de acordo com o método padrão para coleta e descritores de Palmae. Entre os descritores avaliados neste estudo, somente o número e o comprimento de rachillae foram muito diferentes entre os acessos. Quinze acessos de O. minor tiveram o número e comprimento de rachillae variando de 25 a 64 e de 32 cm a 59 cm, respectivamente. Para oito acessos de...

This review is focused on the applications of genome cryobanking of aquatic species including freshwater and marine fish, as well as invertebrates. It also reviews the latest advances in cryobanking of model species, widely used by the scientific community worldwide, because of their applications in several fields. The state of the art of cryopreservation of different cellular types (sperm, oocytes, embryos, somatic cells and primordial germ cells or early spermatogonia) is discussed focusing on the advantages and disadvantages of each procedure according to different applications. A special review on the need of standardization of protocols has also been carried out. In summary, this comprehensive review provides information on the practical details of...

Evaluation of economically important traits from sixteen parental strains of the silkworm Bombyx mori L (Lepidoptera: Bombycidae)
Provedor de dados: 82
Autores: Zanatta,Daniela B; Bravo,Juliana P; Barbosa,Joice F; Munhoz,Roxelle E F; Fernandez,Maria A.
The classification and characterization of silkworm strains are important for sericulture, which is supported by the constant development of new hybrids. In this study, 16 parental strains of Bombyx mori L from the germplasm banks of the Universidade Estadual de Maringá - UEM, and Associação dos Criadores de Bicho-da-Seda de Nova Esperança e Regiões Sericícolas do Paraná - ACESP, were evaluated regarding biological and productive traits economically important. The Chinese C122-B and C121-A, and the Japanese HA-A and HA-B strains yielded the highest cocoon weight, which is related to the raw silk percentage. Our data will be useful in breeding programs for the production of superior silkworm strains and hybrids.

DNA fragmentation and membrane damage of bocachico Prochilodus magdalenae (Ostariophysi: Prochilodontidae) sperm following cryopreservation with dimethylsulfoxide and glucose
Provedor de dados: 83
Autores: Martínez,José Gregorio; García,Víctor Atencio; Carrasco,Sandra Pardo.
The endangered bocachico Prochilodus magdalenae is a native freshwater fish of Colombia, the most captured species locally and one of the most important species for ex-situ conservation (germplasm banks). The aim of this study was to examine the effect of three concentrations of Dimethylsulfoxide (DMSO) (5%, 10%, 15%) and three of glucose (305, 333, 361 mM) in the extender on spermatic DNA fragmentation (F-DNA) (by Halomax®, Chromatin dispersion) and membrane damage (D-Me) (by eosin-nigrosin staining). After assessment of sperm quality by computer analysis of motility, one part of semen from males was diluted separately with three parts of extender and filled into 0.5 ml straws. Freezing was carried out in liquid nitrogen vapor dry shipper for 30 minutes...

A imbuia (Ocotea porosa Nees et Martius ex. Nees, Lauraceae) é uma espécie da Floresta Ombrófila Mista de valor econômico por possuir madeira de alta qualidade para mobiliário de luxo. Acha-se ameaçada de extinção e, por isto, a Embrapa Florestas vem desenvolvendo coletas para a instalação de um banco de conservação de germoplasma em outubro de 2004 em Santa Catarina. Apesar de sua importância, estudos relacionados aos componentes de variância de características das sementes de imbuia (Ocotea porosa) como subsídio à seleção fenotípica de sementes não se acham presentes na literatura. No presente trabalho foram realizadas mensurações do peso e do maior diâmetro de sementes de imbuia das populações de Canoinhas e Caçador, Estado de Santa Catarina para a...

Sensitivity of brazilian-pine (Araucária angustifolia) embryos to desiccation and temperature
Provedor de dados: 190
Autores: Medeiros, Antonio Carlos de Souza; Walters, Cristina; Hill, Lisa.
The “recalcitrant” behavior of Araucaria angustifolia (Bert.) O. Kuntze seeds (Brazilian pine) limits the conservation of genetic resources of this important species in ex situ genebanks. As initial steps in developing storage protocols, we studied the interaction of water content and temperature on embryo survival. Embryos were excised from seeds and “flash-dried” to water contents as low as 0.29 g water/g dry mass and then exposed to 0°C, -5°C and -18°C for 4 h. Drying rate was calculated from drying time courses and expressed as (g water / g dry weight) / hour. Other authors have studied the effects of desiccation of whole seed of A. angustifolia on viability. In order to compare moisture content of whole seeds to that of embryonic axes, seeds of A....

Exploitation of imbuya (Ocotea porosa) occurred at the same time of Araucaria angustifolia. Imbuya is threatned of extinction, owns a valuable wood and for these characteristics, Embrapa Florestas, located at Colombo, State of Paraná, Brazil, decided to make efforts for its conservation ex-situ. Collects in Southern Brazil at the localities of Caçador, Canoinhas (State of Santa Catarina), Colombo and Bocaiúva do Sul (State of Paraná) were realized. A complete randomized design was used in 12 months age seedlings. In this experiment, height of thirty one progenies ordered in plots of five plants with four replications was measured. The general mean for height was 16,55 cm. The additive genetic variance estimate was 72,03, the heritability coefficient...

Autores: Almeida,Vanessa Cavalcante de; Hoffmann,Lúcia Vieira; Yokomizo,Gilberto Ken It; Costa,Joaquim Nunes da; Giband,Marc; Barroso,Paulo Augusto Vianna.
The objective of this work was to characterize the populations of Gossypium barbadense in the states of Amapá and Pará, Brazil. In situ characterization was conducted through interviews with the owners of the plants and environmental observations. Leaf or petal tissue as well as seed samples were collected for genetic characterization by single sequence repeats markers and for storage in germplasm banks, respectively. The plants were maintained in dooryards and used mainly for medical purposes. The genetic analysis showed no heterozygous plants at the loci tested (f = 1), indicating that reproduction occurs mainly through selfing. The total genetic diversity was high (He = 0.39); and a high level of differentiation was observed between cotton plants from...

Autores: Zaefizadeh,Mohammad; Jamaati-e-Somarin,Shahzad; Ojaghi,Javid; Seyedi,Seyed Mehdi; Zabihi-e-Mahmoodabad,Roghayyeh; Ochi,Mehran.
The objective of this study was to identify gliadin band patterns and the extent of genetic diversity in durum wheat genotypes from Northwestern Iran and the Republic of Azerbaijan. Gliadins from 46 landraces and four cultivars were evaluated through acid PAGE analyses. Sixty-six polymorphic bands and 81 patterns were identified. Twenty-four different motility bands and 22 patterns were found in the ω gliadin region with 14 polymorph bands and 20 patterns for α and γ gliadins, and 14 bands and 19 different patterns for β gliadins. The combination of these patterns generated 38 and 39 combinations for Gli-1 and Gli-2 loci, respectively. The genetic diversity index (H) was higher for α gliadins (0.924), followed by ω and γ gliadins (0.899 and 0.878,...

The objectives of this work were to optimize the isozyme electrophoresis technique for Bixa orellana, and use isozyme markers for a preliminary survey on the genetic variability in Brazilian annatto germplasm accessions. Collection consisted of seed samples from sixty open pollinated trees, representing two Northern and four Southern geographic provenances. The extraction, electrophoresis, and interpretation of annatto isozymes are described. Three out of the twenty-one identified isozyme loci were polymorphic in the collection. The percentage of polymorphic loci (P = 21.05) and the expected heterozygosity in annatto (H T = 0.064) were low, compared to other tropical woody species. A UPGMA phenogram, constructed with Nei's genetic distances, clearly...

Provedor de dados: 86
Autores: Mezette,Thiago Fonseca; Blumer,Caroline Groppo; Veasey,Elizabeth Ann.
The objective of this work was to characterize morphologically and molecularly the genetic diversity of cassava accessions, collected from different regions in Brazil. A descriptive analysis was made for 12 morphological traits in 419 accessions. Data was transformed into binary data for cluster analysis and analysis of molecular variance. A higher proportion of white or cream (71%) root cortex color was found, while flesh colors were predominantly white (49%) and cream (42%). Four accession groups were classified by the cluster analysis, but they were not grouped according to their origin, which indicates that diversity is not structured in space. The variation was greater within regions (95.6%). Sixty genotypes were also evaluated using 14 polymorphic...

Autores: Day-Rubenstein,   Kelly A.; Heisey,   Paul W.; Shoemaker,   Robbin A.; Sullivan,   John; Frisvold,   George B.
Crop genetic resources are the basis of agricultural production, and significant economic benefits have resulted from their conservation and use. However, crop genetic resources are largely public goods, so private incentives for genetic resource conservation may fall short of achieving public objectives. Within the U.S. germplasm system, certain crop collections lack sufficient diversity to reduce vulnerability to pests and diseases. Many such genetic resources lie outside the United States. This report examines the role of genetic resources, genetic diversity, and efforts to value genetic resources. The report also evaluates economic and institutional factors influencing the flow of genetic resources, including international agreements, and their...

Autores: Tiersch,Terrence R.
Initial success in sperm cryopreservation occurred at about the same time for aquatic species and livestock. However, in the 50 plus years since then cryopreserved sperm of livestock has grown into a billion-dollar global industry, while cryopreserved sperm of aquatic species remains a research activity with little commercial application despite work in more than 90 species and more than 200 published reports. Most research work has focused on large-bodied culture and sport fishes, such as salmon, trout, carp, and catfish, and mollusks such as commercially important oyster and abalone species. However, only a few studies have addressed sperm cryopreservation in small fishes such as zebrafish, or in endangered species. Overall, this work has yielded...

ABSTRACT Some germplasm collections have a high number of accessions, which makes it difficult to explore the genetic variability present in the germplasm bank due to the redundancy and the difficulty of detailed analysis of all conserved accessions. Therefore, our study aimed to analyze the genetic diversity of 153 lima bean (Phaseolus lunatus) accessions for the purpose of constructing a core collection. Eleven SSRs were used for this purpose. The 153 lima bean accessions can be represented by low redundancy using a minimum of 34 accessions, thus representing 22 % of the size of the entire germplasm bank. The core collection had a higher Shannon diversity index and expected heterozygosity (1.906 and 0.811, respectively) than those presented by the entire...

Autores: Scheneiter,Omar; Rosso,Beatriz; Corletto,Mauro.
When breeding temperate forage species is investigated, some attributes such as herbage accumulation and seasonal growth patterns have to be considered. To modify some of these traits, knowledge of the detailed process might be useful. In order to evaluate seasonal growth of contrasting white clover populations an experiment was carried out. Treatments were five cultivars and three local populations collected in Argentina. Weekly measures were taken during each season to calculate leaf appearance and flower appearance rates, stolon growing rate and dry matter (DM) net accumulation. Different germplasm of this species have different mechanisms for DM accumulation. Leaf size, more than leaf appearance rate, was the variable with most differences among...

Autores: Fávero,Alessandra Pereira; Nass,Luciano Lourenço; Cargnin,Adeliano; Leonardecz Neto,Eduardo.
The genus Arachis has 69 species, the majority native to Brazil. Arachis spp. seedling root tips have been used to obtain dividing cells for cytological preparations. Several wild species produce small amounts of seeds and consequently few root meristems, making the cytogenetic characterization very difficult. The purpose of this study was to evaluate the rooting capacity of several wild species of Arachis using the detached leaves technique for obtaining roots from petioles. One hundred and thirty accessions and 27 interspecific hybrids were studied. Three evaluations were performed at 15, 31, and 49 days after planting. Leaf rooting observed in the wild species confirmed the great genetic variability typical of the Arachis genus, indicating that the...

ABSTRACTIn this work, the genetic relationship among twelveGarcinia cambogia (Gaertn.) Desr. accessions were evaluated using Random Amplified Polymorphic DNA markers. The samples were part of the germplasm collected and maintained at NBPGR Regional station, Thrissur, India. Out of thirty RAPD primers used for screening, seven primers produced a total of 128 polymorphic markers in twelve accessions. The Polymorphic Information Content (PIC) ranged from 0.28 (OPA18) to 0.37 (OPA9) and Marker Index (MI) ranged between 3.61 (OPA12) and 5.93 (OPA3) among the primers used. Jaccard's coefficient of genetic similarity ranged between 0.07 and 0.64. The dendrogram constructed based on the similarity matrix generated from the molecular and morphological data showed...

Old grapevine (Vitis vinifera L.) accessions are a source of genes that could be rescued for use per se or in modern breeding programs. The first step in this rescuing is collecting and characterizing the germplasm from a particular region. This study presents the genetic characterization of 21 grapevine accessions collected from the Atacama Desert in the far North of Chile. Characterization was based on 12 microsatellites (Simple Sequence Repeats, or SSRs) supplemented with Amplified Fragment Length Polymorphic (AFLP) markers. Most of the collected accessions produced red berries and shared the genetic characteristics of the cv. País, an old genotype found throughout America. However, among those red-berried accessions, one showed a severe abortive...

Garlic (Allium sativum L.) is a species of vegetative propagation, showing high morphological diversity. Besides, its clones have specific adaptations to different agroclimatic regions. The objective of this study was to determine the genetic diversity of 65 garlic clones collected in Chile and introduced from different countries, by using RAPD (Random Amplified Polymorphic DNA). Fourty random primers of 10 mers generated a total of 398 bands with an 87% of polymorphism. Each primer amplified between two and 20 bands. The size of the fragments obtained fluctuated between 3200 and 369 bp. The results showed that the clones analyzed had a genetic similarity rate of 94%. In addition, 70% of them were clustered in one major group. However, in spite of that...

ABSTRACT:  The collection and characterization of tomato germplasm are of relevant importance for agriculture. This study aimed to collect and characterize, by way of morphological description and statistical tools for the composition of groups, tomato accesses from the Southern and Serrana regions of the State of Espírito Santo, as well as to establish the tomato germplasm bank of the Ifes - Campus de Alegre. Thirty-seven accessions were collected from different commercial locations of Espírito Santo. The experiment was conducted in the Ifes Campus de Alegre in the Agroecology sector. For the morpho-agronomic characterization, sixteen essential descriptors were used, nine quantitative and seven qualitative. In the color of the ripe fruit, there was the...
