2012 Annual Report
1)to collect and evaluate wildland collections of potentially important rangeland plant species seed and;.
2)to develop new plant materials for these species and increase initial seed supplies of them to permit commercialization by the seed industry. Species that are being developed under this project include the grasses Elymus elymoides, Achnatherum thurberianum, and Leymus salinus; the legumes Astragalus filipes, Dalea ornata, Dalea searlsiae, and Lotus utahensis, and the forb Linum lewisii.
During FY 2012: Wildland collections were made of L. utahensis (Arizona, Utah, Nevada), D. searlsiae (Nevada, Utah), and A. filipes (Nevada). A field trial of 37 L. lewisii populations with a check entry of ‘Appar’ L. perenne was established at Millville, UT. A trial evaluating progress from five cycles of selection for spike production in L. salinus was also established at Millville. Seed increases of E. elymoides pre-variety germplasms (Sand Hollow, Rattlesnake, Toe Jam Creek, Fish Creek, Pleasant Valley, and Antelope Creek) were established and/or harvested. Seed increases were also established for A. thurberianum. Seed increases were harvested for A. filipes (NBR-1), D. ornata (Spectrum), and D. searlsiae (Elephant Knoll).
