Abstract: Many new cultivars and clones followed stock breeding of poplar. Here,resistance to a leaf rust Melampsora rostrupii with 57 poplar species or cultivars was studied using a pathogenic index and a confrontational index. Results revealed strong differences among the 57 hybrid poplars for resistance to the leaf rust. The incidence rate was 0 - 100% with a disease index of 0 - 82.1 and a confrontational phase index of 0 - 100. For poplar species or cultivars (clones) 18 (31.6%) showed high resistance to the rust,6 (10.5%) showed mid-resistance,15 (26.3%) showed low resistance,10 (17.5%) showed mid-susceptibility,and 8 (14.0%) showed high susceptibility. Thus,different poplar hybrid combinations from the same cross showed diversity in resistance to this leaf rust.[Ch,4 tab. 18 ref.]
