Narrative

Evaluated in the Northern Plains Regional Trials at Bluecreek, UT; Green Canyon, UT; Mead, NE; Sidney, NE; Mandan, ND; and Miles City, MT for dry matter forage production, initial stand and persistence. Produced significantly more dry matter forage (3026 kg ha-1) than cultivars Prairieland (2394 kg ha-1) and Pearl (2247 kg ha-1) when combined over six locations and three years. Superior initial stands over other Altai and Basin wildrye cultivars in the NPA trials except for Mead Nebraska. More persistent than Prairieland and Pearl after four years. Seedling vigor, as indicated by seedling emergence from a deep planting depth (7.6 cm), better than Prairieland and comparable to Pearl. Individual seed weight comparable to Prairieland and Eejay, but significantly lighter than Pearl. Approx. 138,888 seeds per kg at 100% purity. Significantly taller, with longer flag leaves that are oriented higher on the culm than Prairieland, Eejay, and Pearl. Also wider flag leaves and longer inflorescences. Dodecaploid (2n-12x-84) and has the same ploidy level as the commercially available cvs. Prairieland, Eejay, and Pearl. The neighbor-joining tree demonstrated that all but one of the 24 Mustang genotypes group together relative to Prairieland, Eejay, and Pearl. The E.ACAG//M.CTTG primer combination distinguished Mustang from the other cultivars.
