Fig. 4: Ancestry versus geography.
From: The genomes of 204 Vitis vinifera accessions reveal the origin of European wine grapes
Continental patterns of ancestry components in cultivated (a) and wild (b) grapevines and nationwide patterns of wine grape ancestry in the top five wine–producing countries in Europe (c, d). Colors represent W2 ancestry (blue), C1 ancestry (orange), C2 ancestry (gray), and W1 ancestry (yellow). Each ancestry component is plotted separately (a, b). Intensity of the main ancestry component is plotted (c). Overlay of all ancestry components is plotted (d). The collection site of wild accessions is indicated by black dots (b). The most representative site of cultivation of each variety is indicate by black dots (c, d). Abbreviations of top wine-producing countries: Italy IT, France FR, Spain ES, Germany DE, Portugal PT.
