The present study was carried out on 40 maize genotypes during rabi 2018 at Agriculture farm, Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharathi. The experiment was carried out in RBD design, with the objectives to study genetic variability, heritability, genetic advance on fifteen quantitative traits and the analysis of variance has revealed that all the 15 characters under study are showing significant difference among all the 40 genotypes. The values of Phenotypic Coefficient of Variation (PCV) are higher while compared to the values of Genotypic Coefficient of variation (GCV). The estimates of GCV and PCV values for characters like shelling (%), ear height, cobs per plant, test weight, ear leaf length, and grain yield have shown higher difference among other characters. Heritability estimates were high to moderate for most of the characters under study. Where in the results of PCV, GCV, heritability and genetic advance have been furnished that selection for cob wt, grain yield, ear length, no of cobs per plant, test weight, ear height would be effective for selection for improvement of yield in this population.
