Variety description
10 August 2026
The plant forms compact spherical heads with an upright rosette, which ensures good ventilation. The leaves have a deeply incised shape, a crunchy texture, and are colored dark red with a transition from green. The variety is characterized by slow bolting and is suitable for cultivation in open field, protected cultivation, and hydroponic systems.
The variety has high resistance to downy mildew (races Bl:29–37, 40, 41EU) and lettuce aphid (Nr:0). The Knox technology is integrated into the crop, which slows down the oxidation of leaf cuts and extends shelf life. The produce is characterized by a high yield of marketable mass and uniformity, and is suitable for sale as whole heads or ready-to-eat leaf fragments.
