Genetic Characterization of Grapevine Cultivars Collected throughout the Dalmatian Region

Eleven SSR loci were used to identify 76 accessions of presumed native Dalmatian grapevine cultivars (Vitis vinifera L.). Plant material was collected throughout the Dalmatian region and used to reestablish a grape germplasm collection in Dalmatia, the Adriatic region of Croatia. The 76 accessions had 63 unique genotypes, of which 35 are published here for the first time. Twelve synonyms were found within the Dalmatian cultivars and 11 Dalmatian cultivars matched previously published genotypes, mainly from neighboring countries, suggesting historic exchange of grapevine cultivars. Several cultivars with similar names had different SSR profiles, making them homonyms. Genetic distance analysis revealed five groups of cultivars and confirmed several distinct grape gene pools in Croatia.
