Turf performance of six perennial ryegrass varieties used for overseeding

The turf characters of 6 varieties of perennial ryegrass, including the speed of seedling emergence, tiller density, texture and turfgrass quality was studied to evaluate their suitability under field conditions in Nanjing. The results showed that 6 varieties performed well in seedling emergence and turf establishment and better adaptability and turf performance during the spring and autumn. Tiller density, turf quality, texture and regeneration speed of the tested varieties declined under the stress of heat in summer, in which, the turf characters of Ignite and Regal 5 were better than other varieties and could be used for overseeding in Nanjing and other regions with the same climate.
