The hybrid forms a vigorous plant with blue-green leaves and a pronounced waxy bloom. The heads have a round shape, dense structure, and smooth surface. Due to high plant uniformity, the variety is suitable for mechanical harvesting.
The plant has high resistance to Fusarium wilt, field tolerance to black rot, and resistance to bolting. The hybrid does not require intensive mineral nutrition and tolerates low nitrogen content in the soil well.
The produce is for universal use, suitable for fresh market sale and short-term storage for up to 4 months. Possesses good transportability. Recommended planting density is from 35–40 to 40–45 thousand plants per hectare.
