Determination of Fox grape genotypes (Vitis labrusca L.) grown in Northeastern Anatolia

Northeastern part of Anatolia is a gene center of grapevine and a wide diversity of Fox grapes grow here. Viticulture and some grapevines in the Black Sea Region (in the north of Turkey) are on the verge of extinction; several types and varieties grown in this region have never been described and did not survive till present. For the past 10 years vineyards and grapevines in the Black Sea Region have been studied. In the present study, eighteen grapevines of foxy taste grown in the Artvin and Rize provinces were described. An ampelographic description of young shoot, mature shoot, young leaf, mature leaf, berry, bunch and seed were carried out using the OIV (Office International de la Vigne et du Vin) list for grapevine cultivars and Vitis species. However, several other parameters of the cultivars were measured for evaluation.
