The hybrid belongs to the oilseed type and is characterized by an early maturity group. The plants are of medium height, have strong stems and a developed root system, which ensures lodging resistance. A developmental feature is the combination of late flowering with very rapid head drying in the autumn period.
The plant possesses genetic resistance to all known races of downy mildew and broomrape. ExpressSun technology provides weed control when using tribenuron-methyl-based herbicides. The recommended seeding rate is 55,000–60,000 plants per hectare.
The produce is intended primarily for oil processing due to its high-oleic composition; additional use of seeds is possible as bird feed. The hybrid is adapted for cultivation in regions with a short growing season.
