Lolium perenne
SR 4660ST
SR 4660ST Perennial Ryegrass (SRX-4MSH) (Lolium perenne) is an attractive, leafy, endophyte- enhanced ryegrass with extremely high levels of salt and drought tolerance. The plants used to develop SR 4660ST were irrigated with salt water during the heat of summer to select the plants that survived salinity and heat. The seed from these plants were also screened for germination with high salt levels to develop a cultivar that survives adversity. It has demonstrated high overall turf performance under various maintenance levels ranging from golf course fairways to residential lawns
Key features
