Variety description

10 August 2026

The variety (hybrid) belongs to the "iceberg" type and is intended for head formation cultivation, including the use of hydroponic systems. During agrotechnical trials, a tendency toward increased stem length was noted, which may negatively affect heat tolerance and the timing of the transition to flowering.

Yield and biomass accumulation indicators depend on cultivation conditions, including the use of shading nets to improve the marketability of the produce. The variety is a subject of phytopathological research, in particular regarding the study of susceptibility to the pathogen Pythium sylvaticum.
