Variety description
10 August 2026
The variety is a hybrid combining the elongated shape and leaf color of Romaine lettuce with the crispy texture and juiciness of Iceberg. The plant forms a compact, cylindrical rosette with intensely green leaves that have strong, flat, and damage-resistant ribs. Head size ranges from 20 to 25 cm.
The plant possesses high resistance to bolting, tip burn, downy mildew races Bl:29-41EU, and aphid race Nr:0. The leaves are distinguished by a sweet taste and long shelf life. The variety is suitable for open field cultivation during warm seasons and is intended for the fresh market and processing, including mechanical harvesting.
