Variety description

10 August 2026

The variety is tetraploid, which ensures higher productivity and resistance to thinning compared to diploid varieties. Studies show high efficiency of this variety when grown in mixtures with meadow fescue.

The breeding of the variety is aimed at increasing resistance to the main clover pathogens, in particular to Sclerotinia and powdery mildew. The crop is intended for use as a fodder plant.
