ABSTRACT
The present investigation was carried out to study the heritability, correlation and path coefficient analysis in 45 hybrids and ten parents. In pooled analysis of variability parameters revealed that the phenotypic coefficients of variation (PCV) were higher than genotypic coefficient of variation for all the characters studied indicating the role of experimental variance to the total variance. The magnitude of PCV and GCV was high for grain yield per plant followed by ear height, number of kernels per row, 100-seed weight, ear length, plant height, ear girth and number of kernel rows per ear. High heritability coupled with high genetic advance as percentage of mean was observed for ear height, grain yield per plant, plant height, number of kernels per row and ear length. In general, magnitudes of genotypic correlations were found to be higher than phenotypic correlations. The results indicated that grain yield was positively and significantly associated with 100-seed weight, ear girth, ear length, number of kernels per row, plant height, number of kernel row per ear and ear height. Days to 50 percent tasseling had largest direct effect on grain yield per plant followed by 100-seed weight, ear length, days to maturity, ear height, number of kernels per row, ear height, number of kernel rows per and plant height.
