Abstract

Introduction. Establishment of vine plantations requires large long-term investments, therefore, for successful cultivation, a complex of economic and biological indicators and properties of grape varieties should be taken into account. The main focus is the yield and quality of the products obtained.

Object. The object of the study are the grape varieties Rubinovyj Magarach and the control variety Cabernet Sauvignon.

Materials and methods. The study of grape varieties was carried out on the Don ampelographic collection named after Ya. I. Potapenko in 2016-2020 The culture of reference is covering, grafted onto the rootstock Kober 5BB, not irrigated. The scheme of planting bushes 3.0 x 1.5 m. The results of the study of agrobiological indicators, productivity, crop condition, organoleptic characteristics and tasting assessments of wines are presented. The study of varieties was carried out according to the methods generally accepted in viticulture and GOSTs.

Results and discussion. The analysis of agrobiological records showed that the preservation of eyes in the covering shaft averaged 71.5% for the Rubinovy Magarachа variety and 75.6% for the control variety Cabernet Sauvignon. The percentage of fruitful shoots, coefficients of fruiting and fruitfulness were higher in the studied variety at the level of 82.3%, 1.4 and 1.8, respectively, in the control variety – 80.5%, 1.3 and 1.6. The average weight of a bunch by years varied from 99 to 176 g in the studied variety and from 76 to 131 g in the control. The yield was more than 13 t/ha, exceeding the yield of the control variety by 62%. Wine tasting scores for the Rubinovy Magaracha variety over the years ranged from 8.6 to 8.8 points, the average score for the entire study period was 8.74. Cabernet Sauvignon has from 8.5 to 8.7 points, the average score is 8.58.

Conclusion. According to the results of the research, the Rubinovyj Magaracha variety stood out as promising in terms of productivity and quality of wine products. Recommended for expanding the range of vine plantations and use in breeding.
