Interpretive Summary: The primary characteristic limiting the use of basin wildrye has been relatively poor stand establishment resulting from inadequate germination and seedling vigor (Evans and Young 1983). Material is needed with improved stand establishment. Because of its improved seedling vigor and establishment, Continental is expected to be a viable alternative to Magnar and Trailhead for use in restoration, reclamation, and rehabilitation of rangelands. Primary beneficiaries are expected to be land management agencies, ranchers, landowners enrolled in USDA conservation programs, and the seed industry.

Technical Abstract: 'Continental' basin wildrye (Leymus cinereus [Scribn. & Merr.] A. Love) has been released as a cultivar for use in rangeland seedings. It was developed from a hybrid between an induced octoploid (2n=56), generated from the natural tetraploid 'Trailhead' (2n=28), and the natural octoploid 'Magnar' (2n=56). Continental has shown similar or superior stand establishment to Trailhead and Magnar in evaluation trials in west-central Utah, northeastern Utah, southwestern Wyoming, and northwestern Colorado.
