Description:
<jats:p>• <jats:italic>Premise of the study</jats:italic>: This work represents the first molecular phylogeny of the economically important genus <jats:italic>Vitis</jats:italic>, an important genetic resource for breeding in grapevine, <jats:italic>Vitis vinifera</jats:italic>.</jats:p><jats:p>• <jats:italic>Methods</jats:italic>: A molecular phylogeny of <jats:italic>Vitis</jats:italic> using a combined data set of three noncoding regions of the plastid DNA genome was constructed from 47 accessions covering 30 species of <jats:italic>Vitis</jats:italic>. The data for the <jats:italic>trnL‐F</jats:italic> marker were combined with previously published data across the Vitaceae.</jats:p><jats:p>• <jats:italic>Key results</jats:italic>: The molecular phylogeny demonstrated monophyly of the genus <jats:italic>Vitis</jats:italic>. Based on the combined analysis of three genes, <jats:italic>Vitis</jats:italic> is split into three clades that mirror the continental distribution of these accessions. The diversity is highest in the Asian clade, but the general genetic distances across taxa from different continents are relatively small.</jats:p><jats:p>• <jats:italic>Conclusions</jats:italic>: The findings support a relatively recent and intense gene flow between East Asia and North America and the possible impact of hybridization on the evolution of the genus <jats:italic>Vitis</jats:italic>. Taxon identity in important stock collections should be screened carefully because roughly 10% of the accessions analyzed in the present study had been misidentified.</jats:p>
