2 Institute Bioresources from Nakhchivan sector of the National Academy of Sciences of Azerbaijan, Nakhchivan, Azerbaijan DOI : 10.52001/vis.2022.13.81.93 Viewed : 2027 - Downloaded : 1626 The article is devoted to the research of polymorphism peculiarities and variability of local grape varieties, which were first discovered as a result of scientific expeditions, organized in 1998-2020 in various vine-growing regions of the Azerbaijan. The study includes the grape varieties, grown in the ampelographic collection of the Azerbaijan Research Institute of Viticulture and Wine-making.
As a result of the research it was found that the gene pool of grapes of Azerbaijan is characterized by a large varietal diversity and polymorphism.
Morphological, biological and economic-technological features of the new discovered 45 local grape varieties were studied for the first time, However, their classification features and geographical background were also clarified. The digital description was conducted on 66 international ampelodescriptors. By clustering of the descriptor indicators, assessment of variability of hereditary characteristics of these grapevine varieties was conducted.
As shown by the results of cluster analysis, polymorphism in grape varieties is observed mainly on agrobiological, economic and technological grounds.
