Variety description
10 August 2026
The variety has a medium-sized head of round or flat-round shape, characterized by rapid filling and development. The leaves feature flat veins and a semi-erect base, which contributes to high yields and facilitates harvesting.
The produce is intended for the fresh vegetable market. The hybrid exhibits high resistance to internal necrosis and vein browning, as well as to downy mildew (races 16–37, 39–41 EU), lettuce aphid (race 0), and lettuce root aphid.
The variety is intended for cultivation in the open field; it is recommended for the earliest planting dates, including under row covers.
