Early maturing variety, developed at Michurinsk State Agrarian University by crossing the varieties Bredtorp and Minay Shmyrev. Author: K.V. Kondrashova. Under state variety testing since 1994.

Medium-height, loosely branched bush. Growing shoots are medium-thick, straight, with moderate pubescence. Woody shoots are straight, long, medium to thick, light-brown, weakly pubescent. Buds are medium-sized, with a pointed apex, light-brown with a slight pinkish tint, very weakly pubescent, deviated from the shoots, solitary. Leaf scar shape is round.

Leaf is five-lobed, medium-sized, green, weakly pubescent. Leaf blade is bare, weakly pubescent, straight or slightly convex. Central lobe is broadly triangular with small additional protrusions. Side lobes are well-expressed, upper sides of side lobes lie on the same straight line, lower sides are sloped, angle between their veins is straight. Basal lobes are well-expressed, their veins spread out. Leaf base has an open indentation of medium depth and width. Teeth are large, serrated. Leaf petiole is medium in length and thickness, bluish, pubescent.

Flowers are medium-sized, light-pink in color. Inflorescences are medium-length, dense.

Berries are large (2.5-3.0 g), round, one-dimensional, black, skin is dense, dry detachable, tart-sweet taste (4.6 points), versatile use. Berry peduncle is medium-length, brownish-green, slightly pubescent. Chemical composition of berries: soluble dry substances - 15.0%, total sugars - 14.2%, titratable acidity - 2.5%, ascorbic acid - 168.0 mg/100 g.

Winter-hardy, drought-tolerant, self-fertile, resistant to anthracnose, white spot disease, bud and spider mites, powdery mildew (affected weakly), yield 10.0-12.0 t/ha.

Advantages of the variety: winter hardiness, drought tolerance, high yield, large berry size, excellent taste, dry detachable, transportability.

Disadvantages of the variety: in favorable years for powdery mildew development, affected by 1.0 point.
