Fruit growing
and viticulture of South Russia

Annotation

Recently, after the adoption of the Federal Law �On Viticulture and Winemaking in the Russian Federation� dated December 27, 2019 No. 468-FZ, interest in the production of wine products from own grapes has increased significantly. In this regard, the cultivation of grape varieties promising for high-quality winemaking, including autochthonous ones, is of great importance. In this regard, the study and evaluation of introduced grape varieties in different growing zones will make it possible to revise the assortment and introduce a �fresh� stream into the breeding programs. The purpose of the research is to assess the prospects of cultivation in ��� �Sober Bash� (foothill zone of the Krasnodar region) of the Italian autochthonous grape variety of late ripening Corvina (Vitis vinifera L.) on the basis of a variety study and analysis of agrobiological, uvological, economically valuable traits and physicochemical indicators. The variety study was carried out in 2019-2021 on commercial vineyards with an area of 0.75 ha, the number of bushes in the variety trial was 15. Vineyards are not irrigated, uncovered, grafted, rootstock is Richter 110, planting scheme is 2.5 x 0.8 m, formation of bush is unilateral Guyot. The Corvina variety, due to the combination of positive parameters (high yield capacity, crop quality, quality of wine), is of interest for cultivation in a non-covering culture with a full range of protection against diseases, as well as for use in breeding programs as a source of quality indicators. The variety has bunches weighing 292 g, berries weighing 1.4 g, the juice is not colored, it accumulates sugar well (up to 27 g/dm3 ), a good balance of acidity (6.1-7 g/l). The tasting score of monovarietal wine is 8.6 points. The disadvantages of the variety include instability to diseases and pests of grapes.
