Variety description

10 August 2026

The plant forms a compact head with a vertically oriented, well-closed base. The variety maintains controlled growth and compactness even under low light conditions. Suitable for sale as whole heads or as part of mixed salads in pots.

The use of Knox technology slows down the browning of cuts after harvest. The variety is resistant to bolting, tipburn, and necrosis. It possesses high resistance to downy mildew races Bl:29-37, 39-41EU, aphid Nr:0, as well as intermediate resistance to lettuce mosaic virus LMV:1.
