Variety description
10 August 2026
The plant forms a slender cylindrical head with a diameter of 25–30 cm. The leaves are dark green, glossy, large, juicy, and crunchy, with a slightly blistered surface and flat veins. The development period of the variety is 55–65 days.
The variety possesses high resistance to downy mildew, lettuce aphid, internal necrosis, and tip-burn. Plants are resilient to temperature fluctuations and have a long period before the onset of bolting.
The variety is suitable for open field cultivation when planted from April to September and for year-round cultivation in protected ground. Planting density is 8–10 plants per 1 m² for whole heads and 13–14 plants per 1 m² for "hearts".
