The hybrid belongs to the early-maturing group with a flowering period of 95 to 105 days. The plants reach an average height of 160–180 cm and form heads with a diameter of 17–18 cm. The oil content of the seeds is 49–50%.
The variety possesses high drought tolerance and resistance to broomrape races A–G, and also demonstrates general stability against diseases and pests. It is intended for cultivation in forest-steppe, steppe, and Polesia zones with consideration for insufficient moisture.
The hybrid is optimized for the Clearfield Plus cultivation technology, ensuring resistance to herbicides of this group. The recommended seeding rate is 45–50 thousand seeds per hectare under conditions of insufficient moisture and up to 55 thousand with sufficient moisture.
