SSR analysis of some synonyms and homonyms of grape cultivars (Vitis vinifera l.) growing in southeastern Turkey

The goal of this study was to analyze the genetic diversity of grape cultivars growing in Diyarbakır and Şanlıurfa by performing SSR molecular identification of the synonymous and homonymous genotypes of 21 cultivars growing in these two regions to investigate the homonyms (Vitis vinifera L. cvs.). Microsatellite analysis was performed using a minimal standard SSR marker set involving 7 highly polymorphic loci (VVS2, VVMD5, VVMD7, VVMD27, VrZAG47, VrZAG62, and VrZAG62). Mean number of alleles per locus was 7.14 (range, 7-9), with the highest number of alleles detected in VVS2 and the lowest in VVMD7, VVMD27. The expected and observed heterozygosity were 0.70 and 0.69, respectively. The dendrogram indicated 3 distinct groups, each of which involved several subgroups. A total of 5 synonyms and 10 homonyms were identified for the 21 genotypes.
