Variety description

10 August 2026

The variety is tetraploid, which ensures an increased sugar content in the plant and the formation of large, succulent leaves. The plant is characterized by a late maturity group, which extends the period of active use as livestock feed.

The produce has excellent palatability and is safe for all types of farm animals. The variety shows increased winter hardiness and resistance to leaf spot, Septoria, and rust, providing high biomass throughout the season.
