Genetic diversity within a common bean (Phaseolus vulgaris L.) collection, comprising 343 accessions from the Iberian Peninsula, was examined using six allozyme markers. Two major clusters corresponding to the Andean and Mesoamerican gene pools were identified. Both gene pools were characterized by specific alleles, with the former exhibiting Skdh 100, Me(More)
White runner bean landraces are greatly appreciated in the North highlands of Spain due to their excellent culinary seed quality. Runner bean cultivars are grown like pole beans. Diversity within a runner bean collection of 31 accessions from the Iberian Peninsula (Spain and Portugal) was examined using morphological, agronomical and seed quality traits.(More)
Characterization of crop germplasm from specific regions helps understand the patterns of genetic variation that facilitates further germplasm collection, characterization, management and their more efficient utilization in genetics, breeding and other studies. Common bean (Phaseolus vulgaris L.) is a traditional crop in the Iberian Peninsula (Spain and(More)
Southwestern Europe has been considered as a secondary centre of genetic diversity for the common bean. The dispersal of domesticated materials from their centres of origin provides an experimental system that reveals how human selection during cultivation and adaptation to novel environments affects the genetic composition. In this paper, our goal was to(More)
The genetic diversity among 10 wild populations of common bean Phaseolus vulgaris var. aborigineus was analyzed by means of RAPD markers and morpho-agronomic data. The study was performed on populations collected from different sites located in the provinces of Jujuy, Salta and Tucumán in northwestern Argentina. Ten quantitative traits and 33 random primers(More)
Wild populations of common bean pertainingto the Andean gene pool are distributedfrom southern Peru to northern Argentina.The objectives of this study were todetermine the genetic structure of Andeanlandraces from northern Argentina, as oneof the potential domestication sites of theAndean domesticated gene pool, and toestablish a correspondence between(More)
Ninety-five common bean (Phaseolus vulgaris L.) landraces from Spain were evaluated in three different environments in northern Spain for their agronomic performance and seed quality. Significant differences among landraces were found for 14 quantitative traits related to phenology, yield and its components, and seed quality traits. Environmental effects(More)
Legumes are the third largest family of angiosperms and the second most important crop class. Legume genomes have been shaped by extensive large-scale gene duplications, including an approximately 58 million year old whole genome duplication shared by most crop legumes. We report the genome and the transcription atlas of coding and non-coding genes of a(More)
Common bean (Phaseolus vulgarisL.) is a traditional crop in Portugal, where farmers growvarieties selected and maintained by themselves. A collection of 88landraces of common bean was evaluated for 17 quantitative andqualitative traits and the biochemical marker phaseolin to displaythe degree of variation of this germplasm. Agronomic data weresubjected to(More)
Colletotrichum lindemuthianum is a hemibiotrophic fungal pathogen that causes anthracnose disease in common bean. Despite the genetics of anthracnose resistance has been studied for a long time, few quantitative trait loci (QTLs) studies have been conducted on this species. The present work examines the genetic basis of quantitative resistance to races 23(More)
