Variety description
10 August 2026
The variety forms medium-sized heads intended for cultivation during spring and summer periods in greenhouses and tunnels. Slow head filling provides flexibility in harvest timing, and the flat base reduces the risk of contamination and simplifies mechanized harvesting.
The plant possesses high resistance to downy mildew (races Bl:29-41EU), lettuce aphid (race Nr:0), and Fusarium wilt (race Fol:4). Tolerance to tip burn and bolting is also noted.
