W-12.10 220 0.74 21% 0.06 (0.014) Wine cultivars with mostly black berry skin color, from Italy (Centre and North), France (Alps and South), Spain (North) and Portugal.
W-12.11 276 0.75 38% 0.07 (0.018) Traditional table grape cultivars originated from Far, Middle and Near East, with mainly white, red, grey or pink berry skin color ; this group gathers most of the seedless grapevine cultivars
W-12.12 352 0.76 14% 0.03 (0.014) Diverse wine and table grape cultivars in particular from Caucasus, Russia and Maghreb

N is the number of genotypes within the group; He represents the non-biased heterozygosity as in Nei [71]; the average relatedness “r” is calculated with the Queller and Goodnight formula [72], and the standard error using 100 jackknifes over loci [30].
