Resistance to fruit cracking high. Variety of universal use. Fruits suitable for drying, compote and juice production. Fruits contain 23% dry matter, 12.8% sugars, 0.88% free acids, 7.9 mg/100g ascorbic acid.
Flowering at medium-early dates, in Novosibirsk — mid-3rd decade of May. Ripening medium, synchronized, at the end of the 3rd decade of July. Enters fruiting on the 3rd-4th year after planting two-year-old seedlings. Propagated by green cuttings and grafting. Lifespan of trunk about 40 years. Highly self-fertile, can be pollinated by other varieties selected at CSBS, except the 'Pлотнокистная' variety. Yield 17-22 kg per tree, at planting 5 x 3 m, 120-145 centners per hectare.
