The territory of Abkhazia belongs to the region of origin of the cultivated grapevine. Wild forms, intermediate forms between wild and cultivated grapevines and a variety of local native cultivars grow here. In the one of the private yards, a grapevine was found, the name and exact origin of which is not known. The vine showed no signs of fungal diseases in the humid conditions of the region during the absence of chemical treatment. The grape harvest was used to make red wine. DNA-fingerprinting of the unknown genotype was performed to determine its origin. Analysis of the identified DNA profile for 9 SSR loci in the international VIVC database did not reveal coincides with any known cultivar. The methods of Principal coordinates analysis and Bayesian analysis were used to compare the unknown genotype with the genotypes of Vitis vinifera L of several geographic groups and varieties - interspecific hybrids. The closest genotype to the unknown form is the variety Isabella (V. labrusca L. × V. vinifera L).
