Variety description
10 August 2026
The hybrid forms a large, flat-round head with a well-closed base and flat leaf ribs having a characteristic brownish-pink tint. The use of Knox technology allows for slowing the oxidation of leaf sap after cutting, preserving the marketability of the produce.
The variety is intended for cultivation in the open field, primarily during the late spring period. The plant has high resistance to downy mildew races Bl:29-40EU, lettuce aphid, Fusarium wilt, and tip burn. The produce is suitable for both the fresh market and processing.
