Variety description

10 August 2026

The variety is classified as a diploid annual ryegrass, possessing increased resistance to low temperatures and frosts. Plants are characterized by early or medium-early maturity, rapid spring regrowth, and the potential to produce a high yield of dry matter.

It possesses above-average resistance to rust and Septoria. Due to good palatability, it is used for feeding all types of farm animals. In agronomy, it is also used to improve soil structure and control erosion as a cover crop.
