Variety description

10 August 2026

The variety is a synthetic breeding line selected for forming a dense turf stand with fine leaf texture and high genetic uniformity. The plant possesses a low growth habit, which allows for reduced mowing frequency and lower biomass production.

This variety contains a high level of endophytes, increasing its resistance to pests, and is adapted to hot, humid summer conditions while maintaining winter hardiness. The variety is intended for high-quality lawns, sports fields, and overseeding into bermudagrass areas, although it may show susceptibility to gray leaf spot in trials.
