Genetic diversity of ancient grape cultivars of the Crimea region

UMR AGAP équipe DAAV (Diversité, adaptation et amélioration de la vigne)International audienceA total of 76 accessions of Crimean autochthonous grape cultivars from the collection of the National Institute of Vine and Wine "Magarach" were genotyped using 22 nuclear and 3 chloroplast microsatellite loci (SSR) to characterize their genetic diversity. The total number of alleles was 238, the mean number of alleles per locus was 10.8 and the range of expected heterozygosity was 0.4-0.88. Several synonyms were identified based on the comparison of microsatellite profiles with INRA and EVD databases. Morphological, eno-carpo-logical and eno-chemical characterization of number of cultivars using BBCH scale and OIV descriptors were performed. A short synopsis of the origin and historical development of Crimean autochthonous grape cultivars is presented
