Principal Component Analysis of Vitis vinifera (n = 14, black), wild Vitis species (n = 14, red), and projected Vitis hybrids (n = 721, gray) based on 19,226 SNPs. Axes show PCs 1 and 2, capturing 47.3% of the variation. Dotted vertical lines represent mean PC1 values for V. vinifera and wild Vitis genotypes.
