The variety belongs to the Batavia group and is used as a standard differential sample for assessing resistance to the pathogen Bremia lactucae, which causes downy mildew of lettuce.
The plant demonstrates a positive response to agrotechnical measures: when using biological preparations based on Trichoderma strains, a significant increase in biomass, head weight, and leaf size is observed.
