Abstract:
To measure the extent of genetic variability, an experiment was conducted among twenty hybrids of quality protein maize and two open pollinated local germplasms in RBD with three replications over two seasons viz., kharif 2017 and pre-kharif 2018. The ANOVA revealed high significant differences among all the genotypes studied for all the characters except shelling percentage. The pooled ANOVA also indicated significant differences among the genotypes as well as among the environments over the two seasons. Highest PCV and GCV were recorded in ear height followed by plant height and ear weight. Highest heritability in broad sense was recorded in grain yield per plant followed by 100 seed weight and ear weight. And genetic advance as per cent of mean was recorded highest in ear height followed by ear weight and number of kernels per ro.
