- Abstract
The article focuses on the registration of Star Lake Indian ricegrass germplasm (Achnatherum hymenoides) that was released on June 1, 2004 as a selected class, genetically manipulated track, pre-variety germplasm. This class of pre-variety germplasm is eligible for seed certification under guidelines developed by the Association of Official Seed Certifying Agencies. This alternative release procedure is being utilized because propagation material of specific ecotypes is needed for ecosystem restoration, potential for immediate use is high, and potential for commercial use beyond specific restoration and reclamation objectives is probably limited. Star Lake was highest in germination with the overall germination mean and median being 11.1 and 1.5%, respectively. Seed of Star Lake and 29 other accessions from southern Utah, northern New Mexico, and northern Arizona was harvested from plots at Kaysville, Utah, in 1996 and germinated without scarification. After the collection was cleaned, it was noted that T-593 consisted of three seed morphs differing in size and shape.
