Variety description

10 August 2026

The variety belongs to the medium leaf size category and is characterized by a tetraploid chromosome set. Biologically, the variety is distinguished by aggressive growth and the ability to form a dense stand due to active rooting.

The plant belongs to the early-maturing group. The variety shows high persistence under intensive grazing and mowing, maintaining a high proportion of clover in the stand throughout a long period of use, including the third year after sowing.

The primary purpose of the variety is to improve the quality and energy value of forage when used in mixtures with perennial grasses, including high-sugar ryegrass varieties.
