Study of diversity of Azerbaijan local grape varieties basing on OIV ampelographic descriptors

This study was carried out on the grape cultivars originated from the regions of Azerbaijan like Garabagh, Ganja-Gazakh, Shirvan, Nakhchyvan and Absheron in 2008-2015. 25 grape cultivars, belonging to V. vinifera L. were investigated. Ampelographic characteristics of these grape cultivars were determined according to the OIV (International Organisation of Vine and Wine) Descriptors for Grapevine. Analyses of the ampelographic features of the studied grape varieties showed that the genotypes considerably differ by their main morphological, biological and technological characteristics.
