Variety description

10 August 2026

The variety belongs to the Little Gem type, sometimes classified as romaine. The plant is compact, forming uniform, dense, rounded heads with a yellowish heart. The compact structure allows growing the lettuce at a higher planting density.

The hybrid is intended for cultivation in protected soil and hydroponic conditions. It possesses complex resistance to diseases, including downy mildew (races 1–28, 29–35, 37, 38, 40, 41EU) and high resistance to the lettuce aphid Nasonovia ribisnigri.
