Abstract
The common bean (Phaseolus vulgaris L.) is the most consumed food legume in the world and is a major source of dietaryprotein, carbohydrates, and valuable micronutrients, especially in developing countries. Diversity Arrays Technology (DArTseq),based on genome reduction with restriction enzymes, provides a rapid, high-throughput, and cost-effective tool capable of generatingthousands of genotyped single nucleotide polymorphisms (SNPs) for a genome-wide analysis of genetic diversity. In this study, weaimed to characterize common bean accessions using SNPs detected by a DArTseq approach. A total of 43,018 SNPs were identifiedfrom 173 common bean accessions, including Andean and Mesoamerican genotypes. After filtering raw and redundant data, a totalof 16,366 SNPs were considered for further analyses. According to population structure analysis, the genotypes were roughly dividedinto 2 gene pools of Andean and Mesoamerican types. Pairwise fixation index (Fst) values were calculated to resolve the differentiationbetween populations. This study demonstrated that discovering SNPs from the whole genome is a potential resource for identifyingnaturally diverse accessions and also the information could be used in breeding programs to develop new common bean varieties.
