The variety was created as a result of selective breeding within five lines of the 'Langedijker' variety. The plant is characterized by a growing period of approximately 120 days, which makes it slightly earlier compared to the 'Dottenfelder Dauer' variety.
The variety is adapted to the climatic conditions of Norway and is suitable for storage. Precise data on plant morphological parameters, such as height or resistance to specific diseases, are not recorded in available sources.
