Early-maturing hybrid with a vegetation period of 60–65 days from the moment of transplanting. The heads have a round shape, a dense structure, are uniform in size, and are distinguished by a bright green color with a glossy sheen. The average weight of one head ranges from 1.0 to 2.0 kg, and under certain conditions, it can reach 2.5 kg.
The plant is low-growing, with dark green leaves with a bluish tint and a pronounced waxy bloom. The hybrid is suitable for cultivation in open field and protected cultivation. It possesses high resistance to thrips damage, is resistant to lodging, and is capable of maintaining market quality in the field for a long time after ripening.
