Variety description
10 August 2026
The plant belongs to the incised-leaf type and possesses a soft, flexible texture. When the base is cut, the rosette separates into many ready-to-eat leaves. The variety is intended for cultivation in open field, distinguished by growth vigor during the winter period and delayed bolting in summer.
The variety possesses high resistance to downy mildew (races Bl:29–37, 39–41EU / Bl:7–10US), lettuce aphid (Nr:0), and downy mildew virus. Thanks to the implemented Knox™ technology, the oxidation of cuts is slowed, which extends the shelf life of the product. The variety is oriented toward the processing market and the production of salad mixes.
