Variety description

10 August 2026

The hybrid is characterized by a medium stem height and a strong root system, ensuring lodging resistance. The head is directed downwards or semi-directed downwards; the seeds have good retention, which minimizes shattering. Oil content in seeds is high.

The plant possesses good drought tolerance and tolerance to broomrape (Orobanche cumana), including aggressive races. In scientific research, the hybrid is often used as a reference standard when studying ecological plasticity and mechanisms of resistance to parasitic diseases.
