Variety description

10 August 2026

The variety is used in agriculture for fodder production and the formation of grass mixtures. It is included in official state registers of agricultural plants as suitable for use in multifunctional meadow ecosystems.

During comparative field trials, the variety showed indicators of yield, development, winter hardiness, and disease resistance that allow it to be recommended for cultivation on par with other recognized redtop varieties.
