The hybrid belongs to the mid-early maturity group and is intended primarily for the production of high-oleic oil, as well as for the use of seeds as bird feed. It possesses technological resistance to sulfonylurea herbicides containing tribenuron-methyl and high resistance to all known races of downy mildew.
The plants are well adapted for late sowing, repeated use in crop rotation, and are suitable for desiccation. The recommended seeding rate is 22,000–24,000 plants per acre.
