Analysis of variance revealed that the differences among forty four hybrids were significant for all the characters except 1000 grain weight. Among the all traits grain yield per plant exhibited high estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) followed by number of panicles per plant and panicle weight. Broad sense heritability was highest for plant height and grain yield per plant, which suggested that this trait would respond to selection owing their high genetic variability and transmissibility. High heritability coupled with high genetic advance was exhibited by grain yield per plant and total number of panicle per plant and selection may be effective for these characters.
