AbstractThirty-five populations of H. spontaneum from nine countries, encompassing almost all the known range of distribution of the species, Afghanistan, Crete (Greece), Cyprus, Iran, Iraq, Israel, Libya, Morocco and Turkey, were studied utilizing RFLP markers (21 probes with three restriction enzymes) distributed across all seven barley chromosomes in an attempt to unveil the genetic dissimilarities existing among them. UPGMA clustering, based on the Nei and Li (1979) similarity coefficient, produced a dendrogram where three clusters could be defined: two with a clear geographical distinction (Morocco and Cyprus) and another one grouping all the Asian/Middle Eastern populations, except for an accession from Iran that clustered separately. These results confirm our previous work and suggest that barley domestication could also have taken place outside the Fertile Crescent, particularly in Morocco.
