Variety description

10 August 2026

The variety is used in breeding practice and phytopathological research as one of the components of a test set for identifying races of lettuce downy mildew (Bremia lactucae). In the international IBEB-EU classification, it is included in the D-set for the identification of races of this pathogen.

The variety possesses specific resistance genes to Bremia lactucae, which allows it to be used as an indicator when testing the virulence of new fungal isolates. Detailed data on the commercial characteristics of the plant are absent in open publications, as the variety is a specialized tool for breeding control.
