Six maize genotypes viz. EV-1089, EV-1098, EV-5089, EV-5098, EV-6089 and EV-6098 were tested for their yield performance under four different locations of Barani tract. A number of statistics such as genotype mean performance, genotypic variance, genotypic coefficient of variation, equivalence and regression coefficients were estimated to evaluate the environments effect on the grain yield. Keeping in view the mean yield performance of the genotypes over locations and estimates of different statistics, genotype EV-5098 and EV- 5089 may be considered relatively less sensitive to change in environments and can successfully be grown over varied soil and climatic conditions.
