Technical cultivars Iskorka, Yarylo, and Aromatnyi exhibited the highest proportion of intact buds (79–85 %), indicating their strong adaptive capacity. Field resistance assessments showed that table cultivars reached 7 points against downy mildew and 6 against powdery mildew, while Kometa achieved 8 and 7 points respectively. Technical cultivars demonstrated even greater tolerance (8 points against downy mildew, 7 against powdery mildew), enabling a reduction in fungicide applications and contributing to more environmentally friendly viticulture. Yield levels ranged from 12.8–13.8 t/ha for table cultivars and 7.9–13.1 t/ha for technical ones. The high sugar content of the berries and good ripening of the vine confirmed the suitability of technical varieties for the production of various types of wines. Based on winter hardiness, disease resistance, fruitfulness, yield stability, product quality, and cane maturation, the cultivars Kardyshakh Tairovs’kyi, Zagadka, Kometa, Aromatnyi, Iskorka, Yarylo were identified as ecologically stable and highly plastic. Their adoption will support the development of resilient agrocenoses, reduce crop loss risks, and decrease plant-protection costs by 25–30 %. Product Description popup.authors Olena R.
