The hybrid forms dense round-shaped heads. The average weight of one head is from 2.5 to 3.5 kg, however, in a number of sources, indicators in the range of 1.5–3.0 kg are found.
The plant possesses high resistance to diseases, viruses, and thrips damage. The hybrid tolerates dense planting well with a recommended density of 40–45 to 50–55 thousand plants per 1 hectare.
The produce is suitable for fresh consumption, culinary processing, fermentation, and long-term storage. The heads maintain marketable qualities during transport.
