The hybrid is a simple interline variety with a vegetation period of 112 to 120 days. Plant height is 170–200 cm. Thousand kernel weight reaches about 60 g; oil content in seeds varies from 43% to 52%. High lodging resistance is ensured by a developed root system.
The plant possesses genetic resistance to tribenuron-methyl-based herbicides, which allows the use of SUMO technology with an application rate of up to 50 g/ha. The hybrid is characterized by high resistance to downy mildew and broomrape (races A–E or A–G+), as well as tolerance to phomopsis, phoma, and rots.
The variety is intended for cultivation in steppe and forest-steppe zone conditions characterized by an arid climate.
