DArTseq Analysis of Cypriot Common Bean Germplasm Unveils an Assortment of Unexplored Genetic Variability.

ABSTRACT: The common bean (Phaseolus vulgaris L.) is a globally significant crop with a well-documented domestication history and a critical role in food security. Here, we present the first whole-genome genetic characterization of Cypriot common bean landraces and heirloom varieties, originated from remote mountainous areas, using DArTseq-based SNP genotyping. A total of 13,215 high-quality SNPs were investigated from 50 genotypes, indicating a moderate linkage disequilibrium, high incidences of private and fixed alleles, and an overall low heterozygosity. The comparison of varieties indicated that dry and green bean varieties consisted of genetically distinct clusters, reinforced by phylogenetic and Bayesian structure analyses. A few of the varieties, such as "Gliastro" and "Stringless Blue
