Variety description

10 August 2026

The variety is mentioned in scientific publications of the 1980s as an object of experiments studying the effect of temperature and light on the biosynthesis of oleic and linoleic acids in seeds. Its presence in test reports at the Roskilde station in Denmark during the specified period has also been recorded.

Modern data on the variety as a commercial product are absent; it does not appear in current registries or manufacturer catalogs. Existing mentions of the name in a business context often refer to chemical products rather than agricultural crop seeds.
