Microsatellite diversity and genetic structure among common bean (Phaseolus vulgaris L.) landraces in Brazil, a secondary center of diversity

Abstract: Brazil is the largest producer and consumer of common bean (Phaseolus vulgaris L.), which is the most important source of human dietary protein in that country. This study assessed the genetic diversity and the structure of a sample of 279 geo-referenced common bean landraces from Brazil, using molecular markers. Sixty-seven microsatellite markers spread over the 11 linkage groups of the common bean genome, as well as Phaseolin, PvTFL1y, APA and four SCAR markers were used. As expected, the sample showed lower… Show more

“…Bean evolutionary history shows parallels with that of sweet potato. However, as bean genotypes from both American genepools rarely recombined (Asfaw et al, 2009;Burle et al, 2010), it still remains easy to identify original sources in introduced areas.…”

“…This bean was first domesticated in Central and Southern America and is now widely cultivated in the tropics, subtropics and temperate regions (Burle et al 2010). The common bean is produced worldwide to the tune of about 18.3 million tons (FAOSTAT 2009).…”

“…Amongthe five cultivated species of the Genus Phaseolus (P. vulgaris, P. dumosus, P. coccineus, P. lunantus and P. polyantus), P. vulgaris is the primarily cultivated crop with a broad commercial importance (Caicedo et al, 1999). It was first domesticated in Central and Southern America and is now widely cultivated in the tropics, subtropics and temperate regions (Gepts & Debouck, 1991;Burle et al, 2010). World over, common bean has an annual production of about 18.3 million tons (FAOSTAT, 2009).…”
