Variety description

10 August 2026

The plant belongs to the mini-romaine (Mini Romana) type and is characterized by vigorous growth. The lettuce form features an upright base and leaf structure with slight blistering, which facilitates harvesting and preparation for market.

The variety is intended for open-field cultivation in the winter production cycle. It is characterized by good tolerance to temperature fluctuations, resistance to wind loads, and resistance to leaf yellowing.

Possesses high resistance to powdery mildew (Bl:29-37, 40, 41EU) and lettuce aphid (Nr:0), as well as intermediate resistance to lettuce mosaic virus (LMV:1) and Fusarium wilt (Fol:1).
