Selected in 1991 among Chamyalsky plants of the third generation of Far Eastern varieties. Authors: I.L. Baykalov (Republic of Khakassia) and M.N. Matyunin, NIISS named after M.A. Lisovenko. Undergoing state testing since 2001. Recommended for testing in snow-poor zones of Eastern Siberia.

Trees are cold-resistant, reaching 3 m in height, with a crown diameter of 3.5-4 m and medium density. Flower buds are blunt-tipped, while growth buds are pointed. The period of winter dormancy is somewhat longer; during brief winter thaws, the differentiation process does not complete, and flower buds often emerge from winter undamaged. Leaves are broadly rounded in shape, medium-sized, with unevenly serrated edges, slightly convex base, and small apex; dark green in color. Central vein and petiole are red. Flowers are large with a pinkish hue. Self-fertility is not high. Good pollinators include Severnoe Sianie, Siberjak Baykalova, Kantegirsky, Kirovets. Flowering begins on May 11-13.

Fruits are large (25-30 g), round, with a small seam and reddish blush on most of the slightly pubescent fruit surface. Flesh is dense, juicy, and tasty. Fruits contain 12.7% soluble dry matter, 7.5% sugars, 8.4 mg/100g vitamin C, 0.56% pectin.

Ripen in the first decade of August, suitable for fresh consumption and processing; average yield is 11-16 kg. Shows good annual yield. Cold-resistant. In deep snow areas, the root collar may be damaged, making trees susceptible to drying diseases. Recommended for snow-poor zones of Eastern Siberia.

Advantages of the variety: large, tasty fruits.

Disadvantages: not resistant to sunscald.
