Abstract
One independent (physical) and two partially independent (biophysical) indices were compared with a dependent (biological) index for two sets of yield trials in maize (Zea Mays L.). The object was to investigate whether the environmental response of maize genotypes would be affected by different measures of the environment. The four types of indices gave remarkably similar partitioning of the G X E interaction. Although magnitude of the regression coefficients (b-values) changed markedly with change in type of environmental index, ranking of the genotypes was little affected. Therefore, interpretation of the data was not affected by the type of environmental index use1f to assess the environment.
