Storage life 10-15 days in soil storage. Transportability is average.
Fruits are of universal use.
Begins fruiting at 6-8 years. Maximum yield — 146 centners/ha at 19 years of age.
Medium winter hardiness. No tree deaths observed over 30 years. During winter with a total of negative temperatures -2426.5°, at minimum temperature -41.3°, freezing is less than average, flower bud death 45%, flowers 77%. Resistant to scab.
Advantages of the variety: high yields, fruit size, universal use, resistance to scab.
Disadvantages of the variety: insufficient transportability and weak fruit storage life.
