Abstract

The article presents the results of scientific research conducted by the ARRIV&W – branch of the FSBSI FRARC in 2023. As a result of the research, new knowledge was obtained in the field of viticulture and winemaking, data was obtained on the agrobiological potential of autochthonous and introduced varieties in the Don ampelographic collection named after Ya.I. Potapenko, systematization and digitalization of ampelographic resources data was carried out, 3 databases of grape ampelographic resources and the conditions of their growth were created. Varieties resistant to harmful organisms have been identified. Recommendations on the variety assortment and direction of use of autochthonous and introduced varieties have been developed. A method for storing grape plants in in vitro culture, methods for forming a collection and long-term non-transplant storage of grape plants in in vitro culture, ensuring non-transplant storage of microplants for up to 10-12 months have been developed. Breeding material was obtained: 25 sources of valuable traits (large size, productivity, resistance to mildew), 21 seedlings were selected as elite. Two grape varieties were submitted to the State Varietal Testing. An improved technology for obtaining basic planting material has been developed. The technology of adaptation to non-sterile conditions has been improved. Technologies for the production of planting material using PAS and elicitors have been developed. Seven modifications of high-standard grape formations have been developed, and optimal agro-technical parameters for cultivating grapes under various cultivation methods have been determined. Based on the analysis of geophysical, geological, climatic and soil characteristics, experimental data were obtained on the zoning of vineyard lands in the Rostov region, the determination of ecological, agrobiological, technological parameters that determine the terroirs of the Rostov region, the development of technologies that improve the quality wine products.
