Variety description

10 August 2026

The variety belongs to the Butterhead type and is intended for cultivation in the winter period. A key feature is the presence of the Knox gene, which slows down the browning of the cut plant's tissues.

The plant has full resistance to downy mildew (races Bl:29-41EU) and lettuce aphid (Nr:0), and also shows intermediate resistance to Fusarium wilt (race Fol:4).
