The hybrid belongs to the ultra-early maturity group, with a ripening period of 45–60 days after transplanting. The plants form compact, conical heads with light green leaves. The internal structure is dense, the core is virtually absent, and the fruit weight varies from 0.8 to 2 kg.
The plant possesses high vigor and a well-developed root system, which contributes to its adaptation to stressful growing conditions. The heads are characterized by resistance to cracking and suitability for transportation. Genetic resistance to Fusarium wilt, as well as to Alternaria leaf spot and bacterial soft rot, is declared.
