The hybrid belongs to the mid-ripening group and is characterized by an intensive type of development. The plant possesses good growth energy, has a medium or medium-high height, and demonstrates high resistance to lodging and shedding. The hybrid is adapted to various soil and climatic conditions, including arid regions.
The oil content in the seeds is 50–53%, with the oleic acid level reaching 87–89%. The hybrid possesses complex tolerance to downy mildew, phoma, phomopsis, and sclerotinia. It is resistant to broomrape races A–G and is optimized for the application of herbicides using Express and Fluence technologies.
During cultivation, it is recommended to maintain a plant density within 40–60 thousand plants/ha depending on the soil moisture level. To preserve the high quality of the oleic oil, spatial isolation from linoleic varieties at a distance of 200–400 meters should be maintained during sowing.
