Variety description

10 August 2026

The plant has medium growth vigor. The variety forms a dense, round, white head, suitable for harvesting in 3–5 passes. Harvest when planting from late July to early August occurs in the second half of March.

The variety has a very high sensitivity to fungal diseases, in particular to Mycosphaerella, and also shows moderate sensitivity to bacteriosis. On fertile soils, with early planting, there is a risk of forming deformed or double heads.
