Variety description
10 August 2026
The variety forms a large head of stable shape. Thanks to the Knox genetic trait, the cuts and tissues of the plant darken more slowly, which increases the shelf life of the produce and reduces losses.
The plant possesses high resistance to downy mildew races Bl:29-37 and 39-41EU, root rot Fol:1, and aphids Nr:0, as well as intermediate resistance to lettuce mosaic virus LMV:1.
The variety is suitable for cultivation in protected ground using hydroponics or soil, as well as for winter production in open field. It is particularly effective in the packaged produce segment due to the prolonged maintenance of its marketable appearance.
