The plant has high growth vigor and a powerful root system, while maintaining compact dimensions. The leaves are colored grey-green with medium intensity. The heads have a round shape, a white-yellow color, and a dense structure, in which slit-like voids may be observed.
The hybrid exhibits high tolerance to bolting and resistance to Fusarium wilt and cracking. Marketability of the yield reaches 98%. Due to uniform ripening and the ability to remain in the field for up to 10 days after reaching maturity, the variety is convenient for harvesting and transport. It is intended for cultivation in open field and under film covers for sale in fresh form.
