Winter hardiness of trees is moderate, flower buds have high resistance. Resistance to coccomycosis and moniliosis is moderate. The variety is suitable for planting intensive orchards (4 x 3) and requires enhanced fertilizer background.

Advantages of the variety: high winter hardiness of flower buds, self-fertility, good fruit quality.
