Evaluation of the Genetic Contribution of local Wild vines to European grapevine cultivars

A population genetics approasc was used to assess the role of local wild-vine populations (Vitis vinifera ssp. sylvestris) in the domestication and breeding of central and west European grapevine cultivars. The genetic differentiation amnog seven grapevine gene pools (cultivars from Austria and Germany, France, Italy, Croatia, Greece, Spain and Portugal) was low but significant in the nuclear genome (Fst of 0.05) and substantial for a chloroplast marker (Fst of 0.30). Genetic distances correlate with geographic distances amnog regions. The significant differentiation indicates that the rate of gene flow caused by dissemination of cultivated grapevine plants was not suffcient to genetically homogenize the cultivars grown in different regions and suggest that local domestication and introgression of wild vines predominted over the introduction of cultivars from more advanced wine-producing regions.
