This variety was developed at the Far Eastern Experimental Station of VNIIR in 1977 from a cross between the variety 'Ogon' and a pollen mixture (Red Sweet + Summer + Damanka). Authors: V.P. Tsarenko, N.A. Tsarenko. Introduced into the State Register in 1999.

Medium-height bush, 1.5 m tall, broad and dense. Multi-year branches are gray, straight, with flaking bark and numerous lenticels; one-year shoots are brown and hairy. Buds are small, pointed, form in threes; the outer ones are generative, the middle one vegetative. Leaf blade is oval (5.8 x 3.1 cm), wrinkled, corrugated, with a pointed apex and acute base, dark green, hairy on the abaxial side, woolly on the adaxial side. Leaf margin is doubly-ciliate. Petiole 0.6 cm long, medium thickness, woolly, with two linear, glandular-hairy stipules. Flower (1-2), saucer-shaped, medium size, 2.3 cm in diameter, five-petaled, petals white, touching. Stamens 25, single pistil, hairy, stigma hairy. Stigma is positioned above the anthers. Calyx is cylindrical, with strong anthocyanin, hairy on the outside, with five linear-toothed, hairy sepals. Flowering and fruiting type is continuous along the branch on both one-year and multi-year wood (bouquet branches, fruiting twigs).

Fruit is large, average weight 3.2 g, maximum 3.5 g, size 1.5 x 1.4 x 1.4 cm. Fruit shape is oval, slightly tapered apex, sunken base. Ventral suture is in the form of a stripe. Skin color is bright red, glossy, hairy with noticeable short hairs; flesh is red, fibrous, firm, juicy. Juice is red. Peduncle 0.5 cm long, medium thickness, hairy. Stone is oval, pale cream, 0.20 g, constitutes 6.2% of fruit weight, does not detach from flesh.

Fruit appearance is attractive. Flesh is juicy, firm, fibrous. Flavor is tangy-sweet, harmonious. Sensory evaluation 4 points. Fresh fruits contain dry matter — 11.0%, sugars — 8.0%, acids — 0.9%, ascorbic acid — 27.8 mg/100g. Semi-dry detachment, transportability weak. Not suitable for mechanical harvesting. Horticultural use is universal: fresh consumption and preservation (juice, jam, jelly, pastilles, marmalade, compote, wine, etc.).

Flowering period: May 10-17. Ripening period: July 10-20. Fruits ripen simultaneously. Grafted seedlings enter fruiting in 2 years, rootstock in 3-4 years. Plant longevity: 18 years. Variety is self-sterile.

High yield, 9.2 kg per bush. Bush, one-year and multi-year branches are winter-hardy; flowers — resistant to spring frosts. Variety is drought-tolerant, does not tolerate waterlogging. Resistant to coccomycosis, moderately resistant to clasterosporiosis. Under waterlogging, flowers and fruits are susceptible to moniliosis.

High production value: winter hardiness, early fruiting, high yield, large fruit size, semi-dry fruit detachment, longevity. Easily propagated by green cuttings. Suitable for intensive orchards with nearby processing facilities; for nurseries and hobby gardening.

Advantages: large fruit size, good taste, firm flesh, semi-dry fruit detachment, winter hardiness.

Disadvantages: fruit size reduction under heavy yield, susceptibility to moniliosis.
