The hybrid's vegetation period is 101–110 days, with plant height ranging from 160–180 cm. The plant possesses a powerful root system and is distinguished by a rapid growth rate during the initial stages of development.
Seed oil content is 48–55%. The hybrid has high tolerance to phomopsis, phoma, powdery mildew, white and gray rots, and is also resistant to lodging and broomrape races A–F+. It exhibits high drought tolerance.
Various sources provide contradictory information regarding cultivation technology, which may indicate the existence of different versions of the hybrid under the same trade name: resistance to tribenuron-methyl-based herbicides (Granstar technology) and resistance to imidazolinone herbicides (Clearfield technology) are mentioned.
