AmpelogrAphic chArActerizA tion of Some grApe cultiv ArS (Vitis Vinifera l.) grown in South-weStern region of turkey

Abstract

Ten grapevine cultivars (Vitis vinifera l.) were characterized according to the international grape descriptor lists. The morphology of various vine organs of some autochthonous and hybrid cultivars was described at several phenological stages, and pomologycal characteristics were determined during growth cycle. With respect to the ampelographic characters, great differences were observed among the studied cultivars. The relationships between the cultivars were further assessed via UPGMA dendrogram analysis. Certain characteristics were anticipated to play particular role in the constitution of the ampelographic dendrogram. Particular data observed in this study on some autochthonous grapevine cultivars would help to prevent disappearing local cultivars and to preserve germplasm collection.
