The period from transplanting to technical maturity is 140–145 days. The head has a round shape, dense structure, and a short internal core. The head weight varies from 2 to 4, sometimes up to 5 kg. The leaf color is light green, and the surface is covered with a strong waxy bloom.
The hybrid possesses high adaptability to temperature fluctuations, cold periods, and moisture deficiency. It is resistant to Fusarium wilt and cracking, while being susceptible to damage by caterpillars, aphids, and leaf beetles. It is intended for cultivation in open field and protected cultivation; the keeping quality is 4–6 months.
