Description: Cheatgrass (Bromus tectorum) individuals were genetically characterized using polymorphic microsatellite markers. Through analysis of alleles of five polymorphic loci, genotypes were constructed of individuals from four populations in Utah and Nevada. There were 15 different genotypes: Whiterocks, UT, had nine genotypes, Hobble Creek, UT, had seven genotypes, Strawberry, UT, had four genotypes and Potosi Pass, NV, had one genotype that was unique among all areas studied. These results are similar to what has been found in previous germination phenology and head smut resistance tests. Further analysis of cheatgrass populations using these markers will assist in the analysis of cheatgrass head smut host/pathogen dynamics and in the development of a biological control agent for cheatgrass.

Keywords: wildland shrubs, genetics, biodiversity, disturbance, ecophysiology, community ecology
