Abstract
Relevance. The main goals of the research work are the creation of new grape genotypes based on the mobilization of the potential of wild species, native and high-value introduced varieties with high productivity, product quality and resistance to abiotic and biotic stresses, improvement of the methodological base to accelerate the grape breeding process. The gene pool of grapes — 554 varieties was preserved, hybrid fund of more than 700 genotypes of new selection was created. Hybridisation of grape varieties was carried out in 96 combinations to breed high quality varieties of different directions of use, meeting the requirements of modern viticulture and winemaking, hybrid seeds were obtained in the amount of more than 27 thousand pieces, which allowed to select more than 700 promising hybrid forms, including 3 elite forms — candidates for varieties. More than 20 sources of economically valuable traits of grapes were isolated in field conditions on a hard infectious background, including the traits of “resistance to fungal diseases” and “tolerance to root phylloxera”. Phenotyping of more than 50 varieties in agro-ecological conditions of the seaside zone of southern Dagestan and DNA — passportisation and identification of more than 20 indigenous and breeding varieties of the station were carried out. 7 varieties of table and technical direction were submitted to the State Research Institute, in 2023 the table variety of early maturity Yantar Dagestan was entered into the Register of breeding achievements.
