Variety description

10 August 2026

The variety belongs to the large-leaved types of white clover and demonstrates high dry matter productivity. The plant is characterized by good recovery indicators after periods of drought, which allows it to be used for maintaining sward density in pasture mixtures.

Mainstay is used as a highly nutritious forage component that contributes to increasing animal productivity. In breeding work, the variety is often used as a parent form to improve the characteristics of other clover varieties, and in scientific research, it serves as a standard control sample.
