Variety description

10 August 2026

The variety belongs to the butterhead lettuce group and is intended for cultivation in open field conditions. In breeding practice, it is known as a differential line showing susceptibility to specific races of the downy mildew pathogen Bremia lactucae.

This variety is a historical or genetic resource, not a current commercial product. Public sources lack data on its agronomic characteristics, such as yield or plant morphometric parameters, as its primary purpose is research activity.
