Variety description
10 August 2026
The variety forms large, dense, flat-round heads with a high number of outer leaves, flat veins, and a well-closed base. Thanks to Knox technology, the cut and broken leaf areas oxidize slowly and do not darken, which extends the shelf life of the produce. Slow head filling ensures a long harvest window.
The plant is intended for the fresh market and processing; it is recommended for spring and autumn planting. The variety possesses high resistance to bolting, internal necrosis, and vein browning. It has a high level of resistance to downy mildew (Bl:29-37, 39-41EU), currant-lettuce aphid (Nr:0), and lettuce mosaic virus (LMV:1).
