The hybrid belongs to the linoleic type and has a medium stem height, which reduces losses during harvesting. In the maturity phase, the head is tilted, and the plant itself is formed semi-upright. The crop is characterized by vigorous initial growth and high tolerance to stress conditions.
The plant is adapted for cultivation in various agro-climatic zones and is resistant to herbicides based on tribenuron-methyl. High genetic resistance to downy mildew, Sclerotinia, Verticillium wilt, and broomrape is noted.
