Variety description
10 August 2026
The variety forms medium to large heads with light green leaves. The plant is characterized by uniform development, good shape, and head weight. Knox technology slows down oxidative processes, which prevents browning of cuts and increases the shelf life of the produce.
The variety is intended for cultivation in cool seasons, particularly in spring and autumn. It possesses high resistance to powdery mildew, Fusarium oxysporum, and lettuce aphid, as well as intermediate resistance to rots and good resistance to tipburn.
Used for fresh market sales and in the ready-to-eat segment. High resistance to tipburn and delayed leaf oxidation ensure the preservation of commercial appearance during storage and transportation.
