Variety description
10 August 2026
The plant forms a large, vertically oriented rosette with shiny, broad, smooth leaves 22–25 cm long. The variety is distinguished by a compact head shape and the presence of thin veins.
Possesses the Knox trait, which slows down the oxidation of cut surfaces, increasing the shelf life of the produce. Resistant to internal tipburn, marginal leaf burn, and bolting.
The hybrid has high resistance to downy mildew (races Bl:29–31, 34, 36, 39, 40EU), aphid (Nr:0), and intermediate resistance to lettuce mosaic virus (LMV:1). Used for cutting and harvesting lettuce hearts.
