The plant is medium to large in size, semi-open, with a vigorous, vertically oriented foliage. Leaves have a dark green color and a strong waxy bloom. The root system is well-developed. High head placement above ground level contributes to protection against basal rot.
The heads are characterized by density and high-quality internal structure. The variety possesses resistance to Fusarium and cracking during transport. The hybrid is distinguished by uniform ripening and the ability to remain in the field on the root for an extended period.
Recommended planting density is 30–40 thousand plants per hectare. Produce is suitable for fresh consumption, processing, and also short-term storage until March–May if conditions are met.
