Variety description

10 August 2026

The variety is intended for creating professional turf on golf courses, sports fields, and private lawns, and is also used for overseeding existing swards. It is distinguished by its dark green color, fine leaf texture, and ability to form a dense, uniform cover.

The plant possesses pronounced resistance to trampling, rapid recovery after stress, and improved drought tolerance. The variety is characterized by fast germination and active rooting, reaching full coverage in 6–8 weeks. The recommended mowing height is from 1 to 4 cm.

Versions of the variety with GLD and GLR indices possess increased resistance to gray leaf spot. The variety is a specialized turf product and is not intended for use in forage production.
