The hybrid belongs to the oilseed direction of use. A key characteristic is stable resistance to races D and E of the parasitic plant broomrape (Orobanche cumana Wallr.).
In studies of the 1980s, it was established that the application of nitrogen fertilizers at a dose of 60 kg/fed influences the morphology of the hybrid, increasing leaf area, plant height, and stem diameter while simultaneously reducing the total number of leaves.
