THE MAIN RESULTS OF THE RESEARCH WORK OF THE DAGESTAN BREEDING EXPERIMENTAL STATION OF VITICULTURE AND VEGETABLE GROWING IN 2023

The article presents the main results of the research work of scientists of the DBESVVG – branch of NCFSCHVW, carried out in accordance with the State Task for 2023 and the Research Plan for 2022-2026 on the basis of the PFSR of the state Academies of Sciences for 2021-2030. The research results reflect the main directions of the research station: genetic resources, breeding and variety studies of grapes, vegetable and subtropical fruit crops; development of a methodology for the creation and operation of intensive own-root plantations of grapes in the phylloxera infestation zone; obtaining environmentally safe products of grapes, vegetables and subtropical fruit crops. The main objectives of the research work are the creation of new genotypes of grapes, subtropical fruit and vegetable crops 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 stressors; improvement of the methodological base to accelerate the breeding process of grapes; identification of mechanisms for the realization of the genetic potential of indigenous and promising introduced grape varieties against the background of phylloxera infection, mechanisms for the formation of genetic and functional tolerance to the pest and scientific (biological) foundations for the creation of intensive own root plantations of grapes; identification of patterns of accumulation of dry matter and BAS in raw materials obtained from young broccoli plants and secondary products of grape and tomato processing depending on from varietal characteristics, stages of development, harvest period, processing methods; development of scientific and applied bases for obtaining environmentally safe raw materials for the production of functional food products and dietary supplements intended for the prevention of cardiovascular and oncological diseases. The research results expanded the base of genetic sources and methodological approaches for the creation of adaptive grape varieties in the changing climatic conditions of southern Russia, allowed to expand methodological approaches to the creation of root-related grape plantations and management of resistance to stressors, confirmed the fundamental possibility and effectiveness of hormonal management of the development of grape plants from the first year of life, as well as the quality of raw grapes, tomatoes and broccoli to create environmentally safe functional food products and dietary supplements, focused on the prevention of socially significant diseases.
