Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars
Authors: I.P.P. de Menezes, L.V. Hoffmann, T.H. de Lima, A.R. da Silva, V.S. Lucena and P.A.V. Barroso
Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, wi.. Read More»

Morphological, cytogenetic, and molecular characterization of Arachis kuhlmannii Krapov. & W.C. Greg. (Leguminosae)
Authors: A.P. F�¡vero, A.P.S. Pe�±aloza, C.R. Lopes and J.F.M. Valls
Arachis kuhlmannii occurs in Mato Grosso and Mato Grosso do Sul States, Brazil. Its area of occurrence partially overlaps with that of other species in the Arachis section. Because of their morphological similarities, these species are often mistaken one for another. This study aimed the correct classification of available acc.. Read More»

Farmer variety exchange along Amazonian rivers influences the genetic structure of manioc maintained in a regional Brazilian Gene Bank
Authors: S.B. Sousa, G.F. Silva, M.C. Dias, C.R. Clement and N.R. Sousa
Knowledge of agro-morphological and genetic variability of germplasm diversity is a prerequisite for its use in breeding. The aim of this study was to characterize the genetic diversity of the manioc (Manihot esculenta) Active Germplasm Bank (AGB) at Embrapa Amazônia Ocidental using microsatellite markers. We evaluated 4.. Read More»

Genetic variability of a Brazilian Capsicum frutescens germplasm collection using morphological characteristics and SSR markers
Authors: S.I.C. Carvalho, L.B. Bianchetti, C.F. Ragassi, C.S.C. Ribeiro, F.J.B. Reifschneider, G.S.C. Buso and F.G. Faleiro
Characterization studies provide essential information for the conservation and use of germplasm in plant breeding programs. In this study, 103 Capsicum frutescens L. accessions from the Active Germplasm Bank of Embrapa Hortaliças, representative of all five Brazilian geographic regions, were characterized based on morp..

Genetic diversity of the Arctic fox using SRAP markers
Authors: M. Zhang1 and X.J. Bai2
Sequence-related amplified polymorphism (SRAP) is a recently developed molecular marker technique that is stable, simple, reliable, and achieves moderate to high numbers of codominant markers. This study is the first to apply SRAP markers in a mammal, namely the Arctic fox. In order to investigate the genetic diversity of the .. Read More»

Determination of the genetic diversity among accessions of Senna spectabilis (canafÃ?Âstula) by using RAPD markers
Authors: M.F. Santos1, R.B. Ara�ºjo Neto2, M.P.S.B.C. Nascimento2 and P.S.C. Lima2
Senna spectabilis (DC.) H.S. Irwin & Barneby (Fabaceae; Caesalpinioideae), commonly known as “canafístula” or “cassia”, is widely used in the semi-arid region of northeastern Brazil as a source of forage and timber. The plant presents a high nutritional content in comparison with other forage species that are native to t.. Read More»

Evaluation of powdery mildew-resistance of grape germplasm and rapid amplified polymorphic DNA markers associated with the resistant trait in Chinese wild Vitis
Authors: J. Zhang, Y. Zhang, H. Yu1, and Y. Wang
The resistance of wild Vitis germplasm, including Chinese and American wild Vitis and Vitis vinifera cultivars, to powdery mildew (Uncinula necator Burr.) was evaluated for two consecutive years under natural conditions. Most of the Chinese and North American species displayed a resistant phenotype, whereas all of the European.. Read More»
