The hybrid is characterized by medium plant height and fast initial development. The produce contains over 90% oleic acid under optimal growing conditions. The hybrid is resistant to lodging and adapted for cultivation in dry and hot climate conditions.
The plant possesses resistance to Orobanche cumana races A–G. The level of resistance to Verticillium wilt, downy mildew, and leaf wilt is rated as high, to Sclerotinia head and stem rot as medium, and to Phomopsis as below average, which requires the application of fungicides.
The recommended plant density at harvest is 50–55 thousand plants per hectare under sufficient moisture levels and 45–50 thousand plants per hectare under insufficient moisture conditions.
