Common bean (Phaseolus vulgaris) cultivars, with different plant type and resistance level to the fungus of angular leaf spot and anthracnose, were evaluated aiming to verify interplot effect. Those traits were evaluated through a note scale (1 to 5), used by three evaluators in the case of plant height, and five, in the pathogen resistence. The analysis of variance was performed based on the average of each trait estimated from the evaluators data. Although interplot effect was significant, it was not detected the interaction between cultivars and kind of adjacent plot. So it was concluded that interplot effect do not change the ranking of cultivars, and therefore it might not be a problem for selection. However, the high values of the coefficient of experimental variation, that have been estimated in common bean experiments, might have interplot effect as its main cause, when different genotypes were evaluated.
