The hybrid belongs to the ultra-early maturity group, ripening two weeks earlier than traditional analogs, which allows it to be used for late sowing or in regions with a short growing season. Plant height is 110–130 cm. The variety has high resistance to lodging and downy mildew.
Seed oil content varies in the range of 42–46%, oleic acid content reaches 90%. The hybrid is intended primarily for processing into high-oleic oil and can also be used for feed purposes. Crops are resistant to imidazolinone herbicides using Clearfield technology; the recommended density is 55,000–65,000 plants per hectare.
