Medium-ripening variety, developed at the All-Russian Research Institute of Fruit Crop Selection from crossing seedling 106-1-37-32 (Bredtorp — self-pollination) with the variety Self-Fertile. Authors: T.P. Ogoltsova, S.D. Knyazev, L.V. Bayanova. Under state variety testing since 2001.
Strong-growing, slightly spreading, dense bush. Growing shoots are medium, green, hairless. Woody shoots of medium thickness, grayish in the lower part, yellow-brown at the top, weakly glossy, with long internodes. Buds are medium, yellowish-green with a pink tip, with clearly visible glands, asymmetric, arranged parallel to the shoot, pressed, sessile, spindle-shaped with a blunt tip. Apical bud is free, leaf scar shape is rounded.
Leaf five-lobed, medium-sized, light green, wrinkled, corrugated, folded along the midrib, matte. Central lobe is broadly triangular, significantly longer than lateral ones, with a blunt tip, additional protrusions not expressed. Lateral lobes are blunt and short, angle between their veins is obtuse. Upper sides of lateral lobes are curved downward or spread out, lower sides are strongly curved toward the leaf base. Sutures between lobes are small and sharp. Basal lobes are weakly expressed, their veins are raised upward and directed toward the petiole. Leaf base has a deep open notch. Teeth are large and blunt, petiole is hairy and uncolored.
Flowers are medium-sized, pink, calyx lobes are medium-sized, colored, arranged horizontally. Inflorescence is medium, dense, axis is thick and straight.
Berries are large (1.3 g), round-oval, black, glossy, skin thin, taste sour-sweet, refreshing (4.8 points), versatile use.
Calyx is closed, very small, pedicel is medium-sized, colored. Chemical composition: dry matter — 12.9%, total sugars — 7.5%, titratable acidity — 3.8%, ascorbic acid — 165.6 mg/100 g, anthocyanins — 196.6 mg/100 g, leucoanthocyanins — 325.3 mg/100 g, catechins — 162.9 mg/100 g, total P-active substances — 684.8 mg/100 g.
Winter-hardy, early-bearing, self-fertile (66%), average yield 9.1 t/ha (1.3 kg/plant), with high field resistance to diseases and bud mite, suitable for mechanical harvesting.
Advantages of the variety: stable yield, technological suitability, comprehensive resistance to pathogens.
Disadvantages of the variety: wide base of the bush.
