Introgression of a Drought Tolerant Festuca Mairie Genome Into an Agronomically Desirable Lolium perenne

Detailed Technology Description

Introduction Perennial ryegrass (Lolium perenne L.) is a diploid cool-season bunch-type grass that is widely used for turf purposes. It germinates rapidly and is quick to establish—characteristics that have led to its frequent use in turfgrass mixtures in both the temperate and transition climatic zones. Perennial ryegrass is used in lawn, golf course tees and fairways, and some highly maintained athletic fields because it tolerates relatively short mowing heights and traffic while providing a good playing surface. It is broadly adapted to cool, temperate climates, and moist environments. However, perennial ryegrass is the least drought-tolerant grass species. As water conservation increases in importance, irrigation of landscapes will be severely restricted. Development of improved drought-tolerant cultivars is a high priority in perennial breeding programs. Description of Technology Michigan State University’s invention crosses perennial ryegrass (Lolium perenne L.) and Atlas fescue (Festuca mairei) to develop a plant combining important turf traits of perennial ryegrass and improved drought tolerance of Atlas fescue.
