Conteúdo: | The objective of this study was to verify the influence of the environmental index on the analysis and estimates of adaptability and stability parameters, using environmental indices obtained from 4 genotype groups (A, B, C, and QPM). Data of preliminary maize cultivars trials of Embrapa maize and sorghum, were used obtained in the 2000/01 harvest season in 9 environments of the southeast and central-western regions of Brazil (Sao Paulo, Goias, Minas Gerais and Parana). The interchange of environmental indices did not affect the parameter estimates and the genotype classification of the 4 groups equally in relation to their stabilities of yield and response to environments. The cause of this variation is probably more linked to the experimental errors and the differences in the interaction of the genotypes of each group with the environments than to the covariance of the genotype means with their respective environmental indices.
