The hybrid belongs to the oilseed direction and possesses high seed productivity and oil yield. It is often used by researchers when creating isogenic lines with specific oil quality parameters, including high-oleic varieties with varying tocopherol content.
The plant possesses confirmed resistance to Phomopsis (Phomopsis/Diaporthe sp.) and good drought tolerance. The hybrid was also studied as a honey plant, evaluating nectar productivity and the effect of bee visitation on final yield.
