Obtained at the All-Russian Research Institute of Lupine from crossing Compact Venyaminova x Leningradskaya Chornaya. Author M.V. Kanshina. Introduced into the State Register in 2001 for the Central Region.

Small tree, fast-growing, with a spherical, slightly raised, dense crown. Buds large, strongly pointed, vegetative conical, strongly deviated, generative ovate, strongly pointed. Leaves ovate, green, young pigmented, apex sharply pointed, base rounded, double-toothed margin, flat blade, short petiole, medium thickness, with 2 pigmented glands. Inflorescence has 3 flowers, large, corolla saucer-shaped, petals overlap one another, stigma positioned at the same level or slightly above the stamens, calyx cup-shaped, calyx lobes pigmented, no toothed margin, stamens and stigma long.

Fruit: average weight 4.2 g, maximum 6.7 g, height 19 mm, width 19 mm, thickness 16 mm. Fruits are round, dark red, flesh and juice dark red, pedicel medium length and thickness, easily separates from the fruit. Stone ovate, mass 0.27 g, 6.4% of fruit mass, light brown, apex pointed, base broadly rounded, easily separates from flesh. Fruits are attractive, juicy, sweet, taste 4.2 points, dry detachment, do not crack, versatile use, contain 17.7% dry matter, 11.6% sugars, 0.45% acids, 13.4 mg/100g ascorbic acid.

Flowering and ripening are early. Enters fruiting on the 4th-5th year. Fruits on cluster branches (63%). Self-pollination yields up to 5% fruit set. Best pollinators — Iputy, Bryanskaya Rozovaya, Revna, Tyutchevka, Radiitsa. Average yield 102 centners/ha, maximum -206 centners/ha. Winter hardiness is good. After severe winters, tree damage was 0.3 points, flower buds 34%, after spring frosts 19% of stamens died. Resistance to coccomyces and moniliosis is high, to clasterosporiosis — medium.

Advantages of the variety: low trees, and flower buds' resistance to spring frosts, annual, abundant fruiting, early fruit ripening.
