Abstract

This study presents the results regarding the identification and discrimination of twenty seven possible clones of grapevine cultivar Korinthiaki staphis (Vitis vinifera L.), three biotypes of Korinthiaki lefki and the related cultivar Staphidampelo using the ampelographic description and the molecular method AFLP. The results from the statistical analysis showed that all the biotypes of cultivar Korinthiaki staphis show small distance and are grouped in the same cluster, depending on their origin, while Staphidampelo and Korinthiaki lefki are neither variants nor biotypes of the cultivar Korinthiaki staphis but different cultivars since they are very distant compared to the other biotypes and moreover, Korinthiaki lefki is in a separate cluster of the dendrogram. The ampelographic description in combination with the molecular method AFLP are effective for the study of the between and within genetic diversity of grapevine cultivars as well as for their identification and discrimination. The results of this study can constitute the base for the implementation of the clonal selection for grapevine cultivar Korinthiaki staphis and the seclusion of the desired clones.
