American elm seedlings vary widely in amount of shoot elongation after inoculation with the Verticillium wilt fungus. This experiment tested the hypothesis that variation in tolerance to the fungus is inherent. Five hundred and ninety-four inoculated seedlings produced an array of seedling heights suggesting that host response ranged from high to low susceptibility. Seedlings from 5 different segments of the array were vegetatively propagated and inoculated to verify initial host response. Comparison of stem elongation for 10 fungus-treated and 10 control ramets per clone revealed that for some clones, fungal inoculation produced negligible growth suppression. For other clones, growth suppression was marked. These responses illustrate genetic variation in tolerance to the fungus. Growth response of an individual clone did not necessarily correspond to growth response of the selected seedling from which the clone was produced. Clonal testing is required for identification of elm genotypes that tolerate this fungus. Forest Sci. 21:227-231.
