Within the Festuca ‐ Lolium genome complex there is a need for rapid development of improved germplasm resources. Traditional recurrent selection methods for population or synthetic development are labor intensive and time consuming. One objective of our research is to identify novel genetic methods that will enhance traditional breeding methods and facilitate the development of improved Lolium spp. germplasm resources. IL2 (Reg. No. GS‐8, PI 659068) represents a diploid, narrow‐based Lolium perenne L. subsp. multiflorum (Lam.) Husnot that is capable of inducing chromosome or genome loss following interspecific hybridizations with Lolium arundinaceum (Schreb.) S.J. Darbyshire and is being released as genetic stock by the USDA‐ARS, Grazinglands Research Laboratory, El Reno, OK. IL2 was derived from a single diploid population (GRL1) identified in a ryegrass population that segregates for varying levels of pollen sterility. The use of this material as a genetic stock can provide a novel approach for the development of Lolium arundinaceum cultivars.
