Medium maturity variety (second decade of June). Enters fruiting early — on 3-4th year after planting. High yield — 45-50 kg from an 8-year-old tree. High winter hardiness of tree and flower buds. Leaves moderately affected by coccomycosis. Pruning performed on improved open-layered crown. Variety requires sunlight, warmth, moisture, and well-drained soils. Responsive to fertilizer application and rejuvenating pruning. Requires conductor transfer to lateral branch at 3.5-4 m. Requires measures to protect against pests and diseases.

Advantages: very early fruiting, high-yielding, high winter hardiness; fruits large, attractive, dessert-like, excellent taste; fruits and leaves moderately resistant to coccomycosis, fruits resistant to cracking in rainy weather.

Disadvantages: large tree size, unsuitability for mechanical harvesting, low transportability, self-sterility.
