Variety description

10 August 2026

The hybrid belongs to the simple hybrid type and is intended for cultivation using the DuPont ExpressSun system. The plants possess genetic resistance to the effects of tribenuron-methyl, which allows for post-emergence herbicide treatment of crops for the control of broad-leaved weeds.

The plant is characterized by resistance to lodging and shattering, and is also a good self-pollinator. The hybrid possesses tolerance to common sunflower diseases and resistance to broomrape races A–E.
