Abstract: The purpose of this study was to determine whether branch gall size of lodgepole pine can indicate the level of resistance towards Western Gall Rust. The diameters of galls were measured from different infection years on the same individuals. The ratio of Gall diameter to Branch diameter was calculated and then correlated with gall incidence. An additional statistical test of Completely Random Design was conducted in hopes of answering the objective. The results suggest that branch gall size cannot indicate level of resistance towards Western Gall Rust.
