Fifteen common bean genotypes (Phaseolus vulgaris L.) were evaluated as to adaptability and stability of grain yield in five environments for crop season and late crop season, during 2006 and 2007. Adaptability and stability were estimate by Eberhart and Russell (1966) and by Wricke e Weber (1986) methods. The results indicated a strong genotype x environment interaction, for four genotypes that presented in crop season, due to significant deviations of regression values. Due to high grain yield and insensitivity to environment changes the genotypes CHC 97-29 is indicated in crop season, FAM 03 and CHC 97-15 in late crop season for southern region of Brazil. FAM 03 responds significantly to good conditions in environment in recommend growing season and should be recommended to be cultivated with modern technologies.
