The purpose of this paper was to assess which environmental factor(s) (location, sowing season or years) in the common black bean genotypes interaction was more expressive and to verify the existence of genotypes with broad and/or specific adaptations to sowing season. Data of grain yield of thirteen genotypes were tested in twelve trials of value of cultivation and use during 2003 and 2004 in the south-central region of Brazil. Analyses of variance were performed with the decomposition of genotypes × environments interaction, which allowed a partial isolation of factors, and subsequently, eight trials were used which allowed a complete isolation of factors. The most important interactions were genotypes × years (R2 = 2.5%) and genotypes × locations (R2 = 1.9%), while genotypes × sowing seasons was the least important (R2 = 1.4%). Thus, it is more important to evaluate the genotypes in different locations and years than at different seasons. Most genotypes showed wide adaptation, but some lines showed strong specific adaptation.
