American elm clones of importance in Dutch elm disease tolerance studies

Abstract

We present the background and characteristics of American elm clones that are commercially available or of interest in research on Dutch elm disease (DED) tolerance in the United States. The characteristics of interest include origin, ploidy level, whether available in nursery trade, evidence of DED tolerance, and other comments. The list includes 10 named commercially available cultivars, six additional named American elms of interest, and six numbered clones of interest.
