Variety description
10 August 2026
The plant forms medium-sized, medium-density round heads. Leaves are light green, glossy, with a smooth or slightly blistered surface. The variety is characterized by a long harvest period due to the gradual filling of the head.
Knox™ technology ensures delayed browning of leaf cuts, which increases the shelf life of the produce. The variety has high resistance to powdery mildew (isolates Bl:29–41EU) and lettuce aphid (Nasonovia ribisnigri).
The variety is intended for cultivation in greenhouses and hydroponic systems. Suitable for year-round cultivation, including the winter period with the use of supplementary lighting.
