The goal of this work was to verify the occurrence of interaction between common bean genotypes and environments (G×E) in Pernambuco state, and to identify genotypes with high yield adaptability and stability, for environmental stratification and determination of which factors are more important to interaction. Ten trials were conducted in a randomized complete blocks design with three replications during the rainy seasons of 2007 and 2008. Each trial was composed by 16 genotypes from four different grain types: “carioca” (cream with brown stripes), black, cream and “rajado” (cream with red stripes). The data obtained were: grain yield, weight of one hundred grains, anthracnose reaction, plant architecture and lodging tolerance. Grain yield data were used for analysis of variance, for stability and adaptability analysis according to the methodology proposed by Annichiarico, for factor analysis to environmental stratification, and for joint analysis with decomposition of G×E interaction in genotypes by years and genotypes by locals. G×E interactions were observed for two evaluated traits. The genotypes BRS Pontal, of carioca- type, BRS Campeiro and BRS Esplendor, of black-type, and BRS Agreste, of mulatinho-type combine high adaptability, stability and grain yield in Pernambuco. Locals used to common bean evaluation in this region were informative and, therefore, must not to be eliminated. There is interaction between genotypes, locals and years in this region, showing that genotypes must be evaluated in larger possible number of locals and years, in this importance order.\ud \u
