| Abstract | New grape varieties developed by breeding institutions require careful study to fully unlock the potential of a particular variety in different soil and climatic conditions. Experiments with table, technical, and rootstock varieties conducted in the Right-Bank Forest-Steppe of Ukraine allow us to recommend varieties suitable for industrial cultivation, taking into account market needs. The study of grape varieties was carried out using the method of determining the growth force and the degree of vine ripening – S.A. Melnyk. The suitability of the newly planted grape varieties for research was determined by the method of planting inventory. The vineyard was established on the territory of the Uman NUS in the spring of 2022. The research was conducted in 2022–2023. The objects of research were table varieties: Tairovsky Kardyshakh, Comet, Tairian, Original, Perseus, Kishmish Tairovsky, Zagadka; technical varieties: Rubin Tairovsky, Muscat Odesskyi, Aromatnyi, Zagrei of the selection of the NSC “Tairov Institute of Plant Breeding”, as well as rootstocks: Dobrynya, Kobera 5BB (clone 211161), Riparia x Rupestris 101-14 (clone 4923). Table and technical varieties are grafted onto Dobrynya rootstock. The shape of the bush is a low-stemmed fan-shaped one-sleeve. The layout of table and technical varieties is 3 x 1.5 m, rootstock 3 x 2 m. The soil retention system is black steam. The analysis of the results showed that the highest average degree of bush ripening among table grape varieties was in Comet – 49.6 % and Tairian – 40 %. Somewhat lower rates were found in the varieties Original 35.1 %, Perseus – 34.8 %, Zagadka – 28.5 %. The lowest rates were found in the varieties Kardyshakh Tairovsky – 26.6 % and Kishmish Tairovsky – 18.6 %. Comparison of the degree of ripening of the vines among technical grape varieties showed that the highest rate was in the variety Aromatnyi - 40.9%. the average rate in the variety Muscat Odessansky - 36.7%. The lowest rates were recorded for Rubin Tairovsky – 31.1 % and Zagrei – 31.1 %. Among the rootstock grapes, the average degree of bush ripening was highest in the Dobrynya variety – 24.2 %. The lowest rates were in the Riparia x Rupestris 101-14 variety (clone 4923) – 13 %. The lowest rate was in the variety Kobera 5 BB (clone 211161) – 8.5 %. | ||
