Abstract
The apple cultivar ʻRozochka’ developed by the breeders of Sverdlovsk Horticultural Breeding Station L. A. Kotov and D. D. Telezhinskiy, was included in the State Register of Breeding Achievements recommended for use in the Volga-Vyatka region in 2023. Breeding work and variety studies were carried out in 1990–2020. The cultivar ʻRozochka’ obtained through hybridization of the ʻSerebryanoe kopytce’ and ʻOrlovim’ cultivars is characterized by high yields (up to 12.2 t/ha), excellent winter hardiness, and resistance to scab. The fruits are medium-sized, weighing from 85 to 130 g, with a correct flat-round shape and smooth surface. Their main color is greenish-yellow, but a significant part of the surface is covered with a reddish-dark blush. The flesh is white, moderately dense, fine-grained, juicy, and easily breakable. The taste is pleasant, well-balanced, sweet-sour, with a light aroma. The harvest ripens at the end of summer, and the storage period under controlled conditions can last up to 60 days. The fruits of this cultivar are versatile: they can be consumed fresh or used for further processing.
