Naked barley (Hordeum vulgare var. nudum) is a staple food crop, contributing significantly to global security. Understanding genetic diversity will facilitate its effective conservation and utilization. To determine distribution within among varieties, we characterized 30 naked varieties from Tibet, representing the traditional, modern, germplasm-resources-bank gene pools, by analyzing SSR molecular fingerprints. The results demonstrate abundant in Tibetan particularly those traditional pool that holds much more private (unique) alleles. Principal coordinates STRUCTURE analyses indicate substantial deviation of modern varieties. A considerable amount seed mixture detected suggesting practices using mixed seeds modern-variety cultivation. Cluster further narrow background likely due limited number traditional/germplasm-resources-bank applied breeding. Relationships between increases sample sizes highlight importance sampling strategies for field collections. findings this study have important implications sustainable utilization different types germplasm, both Tibet other regions around world.
