Variety description
10 August 2026
The plant has a slightly flat round shape and high uniformity. The variety is characterized by high resistance to downy mildew (races 29–37, 39–41 EU) and intermediate resistance to lettuce mosaic virus and Fusarium wilt (race 4).
The variety shows high resistance to internal tipburn, rot, and bolting, which allows for cultivation during the summer period. The plant forms a moderately high head with good filling and fine leaf curling.
