Variety description

10 August 2026

The variety has a morphological feature in the form of high stolon density, which keeps growing points close to the soil surface and ensures rapid recovery after grazing. The plant is characterized by good resistance to diseases, pests, and lodging, and it maintains persistence under various grazing management regimes.

The variety demonstrates active growth in the spring-summer period and good productivity in the cool season. It possesses winter hardiness and is suitable for use in pastures for various types of livestock, contributing to improved feed quality due to high protein content and nitrogen fixation in the soil.
