The hybrid belongs to the mid-early maturity group with a vegetation period of 106–115 days and reaches a height of 150–170 cm. The plant has an upright stem and a semi-pendant head; the narrow-ovate seeds are black in color with gray stripes.
The oil content in the seeds is 51–55%. The hybrid demonstrates high resistance to lodging, is tolerant to Phoma, Phomopsis, and downy mildew, and also possesses moderate resistance to white rot. The level of drought tolerance is assessed as medium to high.
The variety is resistant to broomrape races A–E; several sources indicate protection up to race G. The cultivation technology is optimized for the use of the ExpressSun herbicide system, which allows for effective control of dicotyledonous weeds in crops.
