National Elm Trial

" The National Elm Trial is volunteer effort to evaluate and promote the use of Dutch elm disease resistant American and hybrid elms. This effort grew out of the NCR-193 Agricultural Experiment Station coordinating committee on insects and diseases of woody ornamentals. This group consists of researchers and extension specialists located at land grant universities around the United States. The national trial of commercially available elm cultivars currently includes sixteen evaluation sites in fifteen states; thus these elm cultivars will be evaluated over a wide range of growing conditions and hardiness zones. This nation-wide study has one coordinating and reporting system that is based at Colorado State University." [from website Executive Summary]
