Eight cultivars of crested wheatgrass have been released for commercial production and use in the United States and Canada since 1927. Four are fairway types, two are standard types, one a Siberian wheatgrass, and the most recent a cross between fairway and standard. 'Fairway' and 'Nordan' have been produced commercially far more than the other cultivars. Certified seed production has averaged less than 10 percent of the total annual production. Common seed consists primarily of mixed seed from the 1906 introductions including uncertified Fairway and Nordan. Understory grasses should be considered for mixtures with crested wheatgrass, despite the competitiveness of the wheatgrass. 'Hycrest' and 'Ephraim' cultivars offer good potential in the next decade.
