Variety description

10 August 2026

The plant reaches a height of 165 cm, has a flat head with a diameter of about 25 cm, inclined downwards at a 45-degree angle. The hybrid possesses high resistance to lodging, shattering, and a wide range of diseases, including phoma, phomopsis, white and gray rots, rust, and downy mildew, and is also resistant to broomrape (races A–E).

This hybrid is intended for cultivation in the Steppe, Forest-Steppe, and Polissia zones using traditional or resource-saving tillage systems (mini-till, strip-till, no-till). Depending on the seed specification, the hybrid may be intended for use with Clearfield or SU technologies.
