Variability, heritability, genetic advance, interrelationship and path coefficients were estimated for grain yield and eight other agronomic traits in 21 maize genotypes. The genotypes differed significantly for all traits studied. High genotypic coefficient of variation was exhibited by ear height and 1000-kernel weight. Broad sense heritability was high for days to silk, plant height, ear height and 1000-kernel weight; moderate for ear diameter and number of kernels per row; and low for ear length, kernel rows per ear and grain yield. High genetic advance in percentage of mean was observed in ear height and 1000-kernel weight. Grain yield showed positive and significant genetic correlation with days to silk, plant height, ear height, ear diameter and 1000-kernel weight. Days to silk, plant height, number of kernels per row and 1000-kernel weight had strong positive direct contribution towards grain yield. Thousand kernel weight seemed to be most effective for selection in improving towards high grain yield.
