Study of the Traits of Yield and Quality in the Hybrid Generation by Combinations of Tavkveri × Madrasa

Research work carried out at the Azerbaijan Scientific Research Institute of Viticulture and Winemaking on the creation of new grape varieties that meet the requirements of crop production and are distinguished by high productivity and quality, resistance to biotic and abiotic factors, are of great relevance. The article describes the ampelographic features of new hybrid varieties, as well as the patterns of inheritance of properties and traits and the manifestation of dominance and heterosis in seedlings of the hybrid generation, created by selection in Azerbaijan Scientific Research Institute of Viticulture and Winemaking and its experimental farms. The results of the study and comparative analysis of the morphological, biological, and economic-technological features of several hybrid varieties are presented, as well as a digital description of the traits and properties of genotypes, based on the use of ampelodescriptors of the International Organization of Vine and Wine (OIV).
