Variety description
10 August 2026
The plant has a medium size and dark green leaves. It forms a heavy, well-filled head with a neat core, which simplifies harvesting and packing processes. The variety is intended for the fresh market, including single-piece sales, film packaging, or the preparation of salad mixes.
A distinctive characteristic of the variety is the presence of the Knox trait, which slows down the browning of leaf cuts, extending the shelf life of the product. The variety has high resistance (HR) to powdery mildew (Bl:29-40EU/Bl:7-10US) and lettuce aphid (Nr:0), as well as intermediate resistance (IR) to pathogens Rs and Fol:1.
