Variety description

10 August 2026

The hybrid is intended for harvest in summer and autumn. The vegetation period is 77–82 days in the spring-summer cycle and 85–95 days in the summer-autumn cycle. The plant is distinguished by its upright, compact growth and the presence of a waxy coating on the leaves, which contributes to protection against unfavorable factors.

The inflorescences are uniform, white, and well covered by internal leaves. The produce is resistant to discoloration and the physiological disorder known as 'hairiness' (Hb). The hybrid possesses resistance to leaf diseases and fungal infections.

The cauliflower is suitable for sale on the fresh market and for industrial processing. It tolerates humid and cool weather conditions well, however, it exhibits lower growth vigor on heavy soils and under drought conditions.
