Variety description

10 August 2026

The variety belongs to the romaine type and has large, slightly blistered dark green leaves. The plant is characterized by tall and powerful yet compact dimensions, forming a tightly closed inner part ("heart").

The variety possesses complex resistance to diseases, including downy mildew (races I–V) and corky root rot. The plant also demonstrates tolerance to bolting and high resistance to the development of leaf tipburn.

The plant is intended for professional cultivation and is suitable for sale on the fresh market, processing, and the production of lettuce "hearts." It is adapted to the climatic conditions of coastal regions with the possibility of sowing in the spring-summer period.
