Abstract:
The experiment was conducted in a randomized block design with three replications during Kharif, 2021 at RMD College of Agriculture and Research Station, Ambikapur (Chhattisgarh). A total of seventy seven maize genotypes (18 parents and 56 F1’s including 3 checks) were used to evaluate for genetic variability, heritability and genetic advance analysis in 16 polygenic traits. The result of analysis of variance revealed presence of significant variation among the genotypes. The phenotypic coefficient of variation (PCV) was found higher than genotypic coefficient of variation (GCV) for all the traits however, high GCV and PCV were recorded for the traits viz. grain yield plant^-1, biological yield plant^-1, no. of kernels row^-1, ear height, 100-seed weight, plant height, ear length, ear girth and harvest index which showed, direct selection will be rewarding for improving these traits. High heritability (%) together with high genetic advance as percentage of mean (GAM) was recorded for 100-seed weight, grain yield plant^-1, biological yield plant^-1, plant height, ear height, no. of kernels row^-1, ear girth, ear length and harvest index which indicated that these traits are governed by additive gene action hence and are heritable and fixable thus, phenotypic selection for these traits could be rewarding.
