The hybrid is intended for cultivation in the open field. The plant is vigorous, with large leaves intensely covered with waxy bloom and a high stump, which reduces the risk of lower leaf disease infection. Stable head formation is maintained even at high temperatures.
The heads are round in shape, dense and uniform. The harvest is suitable for fresh consumption and processing. The potential storage life is 4–5 months. Recommended planting density is 25–30 thousand plants per hectare.
