The hybrid belongs to the classic type and is intended for oilseed use. The plant is characterized by a pronounced stay-green effect, which allows the leaves to remain green for a long time during the vegetation period.
The variety possesses genetic resistance to seven races of broomrape (A–G) and new races of downy mildew. When cultivated using the classic technology with fertilizer application, the recommended plant density at the time of harvest is 50–55 thousand plants per hectare.
