Variety description

10 August 2026

The variety belongs to the "Mattenklee" type and is a diploid plant. It was selected as a component for grass mixtures with reduced aggressiveness towards other species.

The variety possesses a high level of resistance to stem nematode and powdery mildew. It is distinguished by longevity and the ability to persist in the sward longer than standard varieties.

In the first year of use, the yield of the variety is somewhat lower than that of traditional varieties of this type, however, in subsequent years it shows excellent productivity and stable growth vigor.
