The hybrid belongs to the mid-early group with a vegetation period of 100–110 days. Plant height is 120–135 cm. The hybrid has a yield potential of up to 55 c/ha, and the oil content in seeds is in the range of 50–55%.
The plant has genetic resistance to broomrape (races A–G+) and high resistance to major diseases and lodging. Resistance to sulfonylurea herbicides, particularly tribenuron-methyl, allows for effective control of dicotyledonous weeds in crops.
