Medium-ripening variety, developed at the Siberian Institute of Horticulture named after M.A. Lisavensky.

Obtained by crossing the variety Dikovinka with a selected seedling from open pollination of the Jet variety. Authors: L.S. Sankin, I.P. Kalinina. Included in the State Register of Varieties approved for use in the West Siberian and East Siberian regions in 1998.

Medium-height bush, medium density, moderately spreading. Growing shoots are medium, straight, light-green, hairless, woody parts are light-brown, matte, medium thickness, straight, hairless. Buds are single, large, egg-shaped, with sharp tips, strongly deviated, have a raspberry color. Apical bud is free. Leaf scar shape is rounded.

Leaf three- or five-lobed, large, light-green, matte, leathery, hairless, slightly convex, with clearly expressed veins, wrinkled. Lobes are sharp, with medium notches. Central lobe is wide, with additional protrusions, slightly curled. Side lobes are sharp, directed sideways, angle between their veins is obtuse or nearly straight. Basal lobes are moderately developed, veins are spread out. Leaf base has a deep notch. Teeth are large, sharp, slightly curled, with clearly defined "tips". Petiole is medium or short, medium thickness, with raspberry color on the upper side, located almost at a right angle to the shoot.

Flowers are medium-sized, cup-shaped, sepals are pale-pink, free, moderately curled. Inflorescence is medium and long, 6-8 cm, contains 7-11 berries with medium berry density. Inflorescence axis is green, medium thickness, straight, hairless. Pedicel is thin, long, green, hairless.

Berries are very large (1.6-4.3 g), round, black, shiny, with medium-thick skin, hairless, with many seeds. Receptacle is closed. Taste is sour-sweet (4.5 points). Berries are versatile. Chemical composition: soluble dry matter — 14.0-18.7%; total sugars — 9.0-12.4%; titratable acidity — 2.6-3.4%; ascorbic acid — 87.0-143.0 mg/100 g; pectin substances (on fresh weight) — 1.2-1.6%.

Cold-hardy, drought-tolerant, self-fertile, early-bearing, resistant to powdery mildew and gall mite, weakly affected by anthracnose and septoria (2.0 points), bud mite up to 1.0 point, high-yielding, average yield 15.3 t/ha (4.6 kg/plant), maximum — 46.0 t/ha (13.8 kg/plant).

Advantages of the variety: cold-hardiness, heat tolerance, drought tolerance, resistance to powdery mildew and gall mite, high yield and berry transportability, good taste qualities, large berry size.

Disadvantages of the variety: weakly affected by anthracnose, septoria, and bud mite.
