Technical Abstract: Transportability of genetic markers across cultivated species and their wild relatives allows efficient evaluation of gene pools for the conservation, management, and utilization of genetic resources. Examination of genetic relationships within the genus Vitis, using microsatellite polymorphisms at ten loci, revealed many genetic affinities roughly corresponding to the taxonomic series established based on morphological criterion. The marginal heterozygote deficiency observed for most loci suggests substructuring within and between taxa, however, there was significant differentiation between taxa as compared to between series. Overall local differentiation and introgression have played a major role in shaping the phylogenetic structure in Vitis.
