Abstract
Currently, a wide range of wine grape varieties is cultivated in industrial vineyards of various regions of Russia. We compared two wine varieties cultivated in the conditions of the Lower Don region, and assessed the effect of methods of bush management and training these varieties with industrial cultivation technology (planting scheme - 3 x 1.5m) on the quantity and quality of the yield: open-earth high-head plantings of wine variety ‘Cristall’ of Hungarian selection and the variety of interspecific origin ‘Tsvetochniy’, bred in the All-Russian Scientific Research Institute of Viticulture and Winemaking named aſter Ya.I.Potapenko. The data obtained in the course of the research allow us to compare the effect of different management methods,
types of bush training and loading with shoots on the indicators of plant fertility, as well as the quantity and quality of the obtained yield. The methods of management and training bushes for the climatic zone of the Lower Don region with better results can be recommended for introduction. For the ‘Cristall’ plantings, it is recommended to use a small cup-shaped and two-armed high-stem bush training; for the ‘Tsvetochniy’ plantings - a zigzag cordon and a Y-shaped bush training with loading increase up to 35 shoots per bush, and a planting scheme - 3 x 1.5 m. The recommended methods of management and training grape bushes of wine varieties ‘Cristall’ and ‘Tsvetochniy’ will make it possible to obtain stable and high-quality yields
