Medium-ripening variety, obtained at the Southern Ural Research Institute of Fruit and Vegetable Growing and Potato Cultivation by pollination of the Boskopsky Velykan variety with pollen mixtures of the Altayskaya Desertnaya, Bia, Golubka, Negrityanka, Nina varieties. Authors: V.S. Ilyin, A.P. Gubenko. Included in the State Register of Selection Achievements approved for use in the Ural region in 1986.

Medium-height, dense, moderately spreading bush. Growing shoots of medium thickness, green, slightly curved. Medium-sized buds, solitary, brown, bent, leaf scar shape rounded.

Five-lobed leaf, large and medium-sized, dark green with slight gloss, light green at tips of growing shoots, wrinkled, blade often bent toward the ground at an angle to the shoot. Lobes pointed, central exceeding lateral ones, broadly oval with additional protrusions. Lateral lobes sharp, broad, directed upward toward the sides, angle between their midveins obtuse. Basal lobes moderately developed. Leaf base with deep notch, basal lobes of many leaves touch at the base. Teeth large, sharp. Petiole medium length and thickness, light green, glabrous, positioned at 45° angle to the shoot.

Flowers medium-sized, cup-shaped, brightly colored, sepals narrow, medium length, not fused, ranging from bright raspberry to white (yellow-green). Inflorescences long (up to 9 cm, 11 flowers), dense. Axis thick or medium, slightly curved, green, petiole medium or even short, green.

Cold-hardy variety, highly self-fertile (58-69%), weakly affected by anthracnose and rust, high-yielding, average yield 5.3 t/ha, maximum — 11.0 t/ha (1.6-3.3 kg/plant).

Advantages of the variety: high cold hardiness, yield, resistance to anthracnose.

Disadvantages of the variety: insufficient berry size.
