Evidencia molecular de diferenciación genética e introgresión entre razas de frijol común del acervo andino = Molecular evidence for race structure and introgression among Andean races of common bean
Se utilizó la información generada por 29 microsatélites en 63 accesiones del acervo andino de P. vulgaris para elaborar agrupamientos y calcular índices de prevalencia. Las accesiones formaron grupos que correspondieron a las razas Nueva Granada, Chile y Perú. Se determinó la existencia de notoria introgresión en genotipos de las razas Chile y Perú. = We used the information generated by 29 microsatellite markers in the analysis of 63 common bean (Phaseolus vulgaris) accessions to evaluate clustering and prevalence indices and to determine the similarity and differentiation or introgression among races of the Andean gene pool. We identified three clusters of genotypes which corresponded to the races of the Andean gene pool, i.e. Nueva Granada, Chile and Peru and the existence of introgression between accessions of these three races. Introgression was more common for genotypes in races Chile and Peru , then for the race Nueva Granada.
