|Description:||This study aimed to determine parameter estimates of compensation of common bean lines and verify if the stability of a mixture of lines is higher than of the line components. Six common bean lines were evaluated, pairwise, in equal proportions. The experiments were conducted in 11 environments, where the trait seed yield was evaluated (grams per plot). The positive ci estimate (compensation ability of line i) of cultivar Talismã was highest, indicating the line for mixtures. The combination of the pair Carioca and MA-II-16, with the highest positive sij estimate (specific compensation ability for the pair of lines i and j), was satisfactory. It was observed that the mean contribution of mixtures to the interaction was in the mean lower than of lines in monoculture. The stability was highest in the mixture Talismã and MA-II-8 and the risk of adoption lowest. The estimates of these compensation and stability parameters in mixtures underlying additional information are a support in the choice of lines to compose a multiline.|
