The ripening period of the hybrid is 75–85 days after transplanting. The heads have a flat shape, and their weight varies from 2 to 4 kg. The leaves are thin, with small veins, have a sweetish taste, and the internal stem is short.
The hybrid is resistant to Fusarium wilt and cracking. Intended for universal use: fresh consumption, pickling, and industrial processing. Due to the texture of the leaves, which separate easily, the variety is convenient for preparing cabbage rolls.
Cultivated primarily as a summer-autumn crop. The recommended planting density is about 40 000 plants per hectare.
