Diversity of panel of wild and domesticated barley (Hordeum vulgare) and crop-wild hybrids

Crop-wild geneflow is common when domesticated plants and their wild relatives grow close to each other. The resultant hybrid forms appear as semi-domesticates and were somtimes considered as missing links between crops and their wild progenitors. Wild-growing barleys in Central and Asia, named Hordeum agriocrithon, show hallmark characters of both wild and domesticated forms. 77 wild barley accessions from the collection of the German Federal ex situ genebank hosted at IPK Gatersleben were chosen for genome-wide genotyping. Public WGS data of 315 wild and domesticated were included in the analysis.
