Medium-ripening variety, developed at the South-Ural Research Institute of Fruit and Vegetable Crops and Potato Cultivation by crossing the varieties Seyanets Golubki and Bredtorp. Author: V.S. Ilyin. Included in the State Register of Varieties approved for use in the West Siberian region in 2008.
Medium-height, medium-density, moderately spreading bush. Growing shoots of medium thickness, light green with anthocyanin 'tan' (sometimes significant in some years), hairless. Buds solitary, brown, emerging from the shoots at an angle.

Lobes pointed, middle lobe broad and sharp with additional projections, egg-shaped. Side lobes long, narrow, sharp, tips directed sideways, angle between their midribs straight or obtuse. Basal lobes well-developed. Leaf base with deep or moderately deep notch, rounded. Teeth uneven, from small to large, sharp, not curled, with a clearly visible 'claw'.

Winter-hardy, self-fertile, weakly affected by powdery mildew and anthracnose, average yield 8.0 t/ha, maximum — 19.7 t/ha (2.45-9 kg/plant).
Advantages of the variety: high yield, winter-hardiness, very large berry size, dessert-like flavor, increased resistance to powdery mildew.
Disadvantages of the variety: medium resistance to bud mite.
