Conteúdo: 	The objectives of this study were to assess which environmental factors (local, season or years) are themost important to contribute for the interactions with genotypes of common black beans and to verify the existence of genotypes with broad and/or specific adaptation to the diverse planting seasons in Central Brazil. Data of grain yields for 13 genotypes in 18 field trials used for cultivar registration were utilized, across 2 years (2003 and 2004). Analyses of variance were carried out with decomposition of the genotype x environment interactions. Firstly, data of 18 trials were used, allowing a partial isolation of factors and, subsequently, eight trials were used to allow a complete isolation of the factors. The genotype x sowing seasons (R2 = 4.2 %) and genotype x year (R2 = 4.1 %) interactions were of the greatest important, while genotype x location was less important (R2 = 3.0 %). It was concluded that is more important to conduct evaluations of genotypes in different seasons and years rather than in different locations. The majority of the genotypes tested presented specific adaptation, although itwas possible to identify superior lines with wide adaptation.
