The hybrid belongs to the mid-maturing group and is characterized by below-average plant height. It demonstrates resistance to a number of diseases: Verticillium wilt, Phomopsis (stem canker), and downy mildew (8 points), Phomopsis and white rot (7 points). The hybrid's drought tolerance is rated at 8 points; a high level of seed oil content is also noted.
Agrotechnical requirements for plant density at the time of harvest are 50–55 thousand plants per hectare under sufficient moisture and 45–50 thousand plants per hectare under insufficient moisture. In conditions favorable for the development of rust, the use of fungicidal crop protection is recommended.
