Medium-ripening variety, obtained at the Institute of Fruit Growing of Belarus by crossing form 2-4D (European subspecies x Siberian subspecies) with a selected seedling from the Far East. Author A.G. Voluznev. Since 1979, it has been included in the State Register of Breeding Achievements approved for use in ten regions of the Russian Federation, except for Western Siberia and the Far East.
Bush is vigorous, dense, medium-spreading. Growing shoots are medium, hairy, matte, with pink-purple tips; woody shoots are medium-thick with thin tips, gray, densely hairy. Buds are medium-sized, slender, elongated, with pointed tips, greenish with pink-gray tinge, slightly deviated from shoots in the middle part but lightly touching the base, tightly pressed at the tips; leaf scar shape is wedge-shaped.
Leaf is five-lobed, medium-sized, light green, matte, deeply wrinkled, blade horizontally positioned. Leaf margin is wavy. Lobes are pointed; central lobe slightly exceeds lateral lobes with additional protrusions. Angle between main veins of lateral lobes is obtuse; lateral lobes are widely spread, upper edges lie on one straight line, lower edges are strongly sloped. Basal lobes are well-defined. Leaf base is triangular with deep notch. Teeth are small and sharp. Petiole is long, medium thickness, green, turning red-purple at the tip by autumn.
Flowers are medium-sized, yellow-green with pink streaks. Inflorescences are long, medium density, hanging.
Berries are medium (1.0 g), uneven, round-oval, black, glossy, with medium-thick skin, sweet flavor (4.6 points), universal use. Peduncle is medium length. Chemical composition: dry matter - 15.3%, total sugars - 7.5%, titratable acidity - 1.8%, ascorbic acid - 239.0 mg/100 g, pectic substances (on fresh weight) - 1.3%.
Winter-hardy, high-yielding (12.0 t/ha), characterized by high self-fertility, no berry drop, moderately affected by American powdery mildew and leaf spot diseases.
Advantages of the variety: high yield, taste qualities.
Disadvantages of the variety: uneven and asynchronous ripening of berries, susceptible to fungal diseases.
