Variety description
10 August 2026
The variety forms a compact rosette with an upright base, which facilitates harvesting and packing processes. The average weight of a marketable head is about 250 grams, and the vegetation cycle lasts from 40 to 60 days.
The plant possesses high resistance to lettuce downy mildew (races Bl:29–37, 39–41EU) and currant-lettuce aphid (Nr:0). The variety is also resistant to internal and external tipburn and premature bolting.
The crop is versatile and suitable for cultivation in open field, as well as in protected cultivation, including hydroponic systems and "plant factories." The variety is often used as a component in complex salad mixes, such as Salatrio.
