Medium-late maturing variety, developed at the All-Russian Research Institute of Fruit Crop Selection from a cross between the varieties 'Bredtorp' and 'Minay Shmyrev'. Breeders: T.P. Ogoltsova, S.D. Knyazev, L.V. Bayanova. Included in the State Register of Varieties Approved for Use in the Northwestern, Central, Volga-Vyatka, and Middle Volga regions in 1995.
Strong, vigorous, moderately spreading, dense bush. Growing shoots are thick, green, shiny. Woody shoots are gray with a light-brown tint toward the tips, glabrous, shiny, thick, evenly tapering toward the top, with long internodes. Buds are medium-sized, rose-violet, asymmetric, conical with a pointed apex, deviated from the shoots. Terminal bud is free; leaf scar shape is rounded-triangular or triangular.
Leaf is five-lobed, large, green, slightly wrinkled, smooth, slightly shiny. Central lobe is larger than lateral lobes, with additional protrusions, broad-triangular. Lateral lobes are short, sharp, angle between their veins is acute or straight. Upper sides of lateral lobes lie on a straight line or at an acute angle to the central vein; lower sides are angled toward the base. Deep, sharp indentations between lobes. Basal lobes are well-defined, veins directed toward the leaf apex or spread out. Base has an open, wide, medium-depth notch. Teeth are small, serrated, broad; petiole is long, thick, colored, glabrous.
Flowers are medium-sized, bell-shaped, calyx lobes reddish, slightly curved downward. Inflorescences are long (up to 8.0 cm), hanging, with central axis; pedicels are hairy and long.
Berries are large (2.1 g), round, black, with a brownish tint, non-uniform, sweet flavor (4.8 points), refreshing. Calyx is rounded, small or medium-sized, half-open; pedicel is medium-length and slightly curved. Chemical composition: total dry matter — 13.7%, total sugars — 8.8%, titratable acidity — 2.8%, ascorbic acid — 117.4 mg/100 g, anthocyanins — 115.4 mg/100 g, leucoanthocyanins — 321.0 mg/100 g, catechins — 237.9 mg/100 g, total P-active substances — 674.3 mg/100 g.
Winter-hardy variety, with good self-fertility (43%), resistant to anthracnose, septoria, and flower malformation, susceptible to powdery mildew, moderately resistant to rust and bud mite. Suitable for mechanized harvest, average yield 6.6 t/ha (0.9 kg/plant).
Advantages of the variety: late ripening, dessert berry flavor, resistance to anthracnose, septoria, and flower malformation, technological suitability.
Disadvantages of the variety: uneven berry ripening, susceptibility to powdery mildew, unstable yield.
