The plant is vigorous, with good foliage. Heads are round, dense, with good internal structure. The average head weight is from 2 to 4 kg, however, in dense plantings, the size can be adjusted downwards to 1.6–2.7 kg.
The hybrid possesses high genetic resistance to clubroot (Pb races: 0, 1, 3) and Fusarium wilt (Foc: 1). The produce is distinguished by head uniformity and good transportability.
Dual-purpose hybrid: suitable for fresh market sales in the summer and autumn, as well as for processing, including pickling.
