Sufficient genetic variability was recorded among five hybrids and five open pollinated varieties of maize. Genotypic and phenotypic correlations were ascertained for grain yield and its components. The results revealed that ear length showed positive and highly significant correlation with grain yield plant-1, plant height, number of kernel rows ear-1 , days taken to tasseling, and days taken to silking. Grain weight showed positive correlation with grain yield plant-1. These characters must be considered in selection for high grain yield.
