The hybrid belongs to the high-oleic type and is intended for the production of goods with a high oleic acid content. The plant is characterized by medium height and good lodging resistance. The grain yield potential is rated as high to very high.
The hybrid possesses resistance to downy mildew, phomopsis, and sclerotinia. Deep, rapidly warming soils with good moisture-retaining capacity are recommended for cultivation. The optimal planting density is from 65,000 to 75,000 plants per hectare.
Cereal crops are preferred as predecessors; maize and root crops are acceptable. Agricultural practice requires timely application of boron in accordance with the needs of high-oleic hybrids.
