Variety description

10 August 2026

The variety forms dense, round-shaped heads. The leaves are dark green with a bluish tint, have a weak to moderate glossy coating and weak blistering. The core is short, and the plant is distinguished by high uniformity and good head weight.

The variety is mid-season: the time to reach marketable maturity is up to 57 days under long-day conditions, and in some conditions — about 80 days. It is adapted to cultivation on organic soils and has a longer harvest period compared to a number of similar varieties.

The variety possesses pronounced resistance to rib discoloration caused by high temperatures, as well as to tipburn and bolting. Tolerance to bacterial leaf spot and Fusarium wilt is noted.
