Hexaploid-octoploid perennial ryegrass, hexaploid-octoploid ryegrass american ryegrass, and hybrids thereof

Abstract

A method of developing hexaploid (2n=6x=42) and octoploid (2n=8x=56) turf-type perennial ryegrass (Lolium perenne L.) and Festulolium [(American Ryegrass), x Festulolium loliaceum (Huds.) P. Fourn. (Festuca pratensis Huds. x Lolium perenne)], and their hybrids with Tall Fescue (Festuca arundinacea Schreb.) including germplasm, cultivars and seed used to produce the grass are provided. These grasses are useful as an improved turfgrass on golf courses, athletic fields and other areas using seeded turfgrasses. The grasses will provide a green improved winter performance and drought tolerance.
