Variety description

10 August 2026

The plant has an upright habit, reaches a size of 17–20 cm, and features thin leaf ribs. The variety forms a well-filled head with a yellow heart, and the presence of a short core facilitates the harvesting and cleaning process.

The variety is suitable for cultivation throughout the entire season, primarily in open field. It possesses high resistance to Bremia lactucae, Fusarium oxysporum, Nasonovia ribisnigri, and Mirafiori lettuce virus, as well as intermediate resistance to Lettuce mosaic virus and Fusarium oxysporum.

The product is available as organic seeds and is oriented toward fresh market use.
