Sažetak
Due to the availability and affordability of large scale genotyping, identification of genomic regions affected by the natural or artificial selection in the populations of wild and domesticated plants became standard procedure in modern population genetics. Identification of these regions and their association with traits of interest helps to understand evolutionary history of the species. The structure of cultivated common bean populations strongly resembles the structure of wild populations due to occurrence of at least two independent domestication events that occurred independently in Central and South America. Long- termed spatial isolation of two gene pools preserved their differential patterns of adaptation. Basic structure in collection of Croatian common bean landraces corresponds to the general pattern: first division is between two clusters of Central and South American origin, and later than divides into two clusters identified by different phaseolin types. In this study we used the differences in allele frequencies between populations (estimated by Fst values) to identify the SNP loci under adaptive selection.
