Variety description

10 August 2026

The variety is characterized by late fruit ripening. The bearing type is lateral, with the ability to set fruit on lateral shoots of up to 50%. The tree is vigorous, forming a narrow pyramidal crown, reaching a height of 14 meters. The angle of branching of skeletal branches is from 45 to 80 degrees.

The fruits are large, weighing about 16 g or more, the kernel yield is 40–43%. Flowering is protandrous with a long flowering period for female flowers (more than 10 days), which requires careful selection of pollinator varieties. The variety is early bearing, starting to produce fruit in the 2–3rd year after planting, and possesses high winter hardiness and relative resistance to diseases.
