Banana improvement programs aim at the creation of new varieties partially resistant to the black leaf streak disease. The principal objective of this study was to characterize the components of this resistance using the infectious life-cycle parameters, to judge their epidemiologic weight and to evaluate the variability of the aggressiveness of the pathogen. Significant differences were detected between partial resistant cultivars for some infectious life-cycle sequences either in natural than in controlled conditions. Some resistance components were suggested. The experimental device used in the field did not, however, allowed to judge the epidemiologic weight of some of them. Elsewhere, a low variability of Mycosphaerella fijiensis aggressiveness was detected and no "cultivar x isolate" specific interaction was highlighted. These results have an implication for the selection of effective and durable partial resistances.
