Variety description

10 August 2026

The variety is intended for creating lawns and demonstrates high resistance to the main types of rust, including stem and crown rust. During field trials, indicators such as turf quality, wear tolerance, drought recovery ability, and winter hardiness level were evaluated.

Specialized morphological descriptions, such as precise plant height or maturity group, are absent in open publications. Information about the variety is presented primarily as data from comparative reports of professional turfgrass trials.
