Abstract
Present study was aimed to investigate the genetic diversity and population structure of Turkish common bean germplasm. A total of 96 bean genotypes were characterized with iPBS-retrotansposons that yielded a mean polymorphism information contents of 0.8. Mean gene diversity and Shannon information index were 0.14 and 0.25, respectively. Neighbor joining analysis divided the bean genotypes into two main group (A and B) according to their geographical regions, growth habits and seed size. Bingol-l7, Sivas-14 and Hakkari-11 genotypes were found very distinct and can be used as candidate parents for the bean breeding. The higher efficiency and reproducibility of iPBS-retrotransposons was witnessed in common bean as compared to earlier studies using the same marker system. Results of this study will boost up the investigators for genotyping the larger germplasm of common bean with minimum laboratory infrastructure in developing and least developed countries.
