dc.description.abstractThe present investigation consisted of 36 hybrids along with 15 parents and 4 checks viz., Pratap Hybrid Maize-3, Vivek Hybrid-43, Pratap Makka -9 and HM-11, the total of 55 entries were evaluated during Kharif-2016 in randomized block design with three replications. The data was recorded on fifteen traits to study the magnitude of relative heterosis, heterobeltiosis, economic heterosis, general and specific combining ability effects. The analysis of variance indicated that mean squares due to genotypes, parents, crosses and parents v/s crosses were significant for all characters except for days to 50 per cent tasseling, days to 50 per cent silking, days to 75 per cent brown husk, number of leaves per plant, cob girth and number of grain rows per cob due to genotypes, days to 75 per cent brown husk and number of leaves per plant due to parents, anthesis-silking interval, days to 75 per cent brown husk, number of leaves per plant, cob girth, number of grain rows per cob and 100-grain weight due to parents v/s crosses and anthesis-silking interval, days to 75 per cent brown husk and number of leaves per plant due to crosses. The significant mean squares or different traits, indicated the existence of appreciable amount of genetic variability under research experimental materials. The inbred line L2 exhibited maximum mean values for grain yield per plant, number or grain rows per cob, harvest index and minimum mean values for days to 50 per cent tassseling and days to 50 per cent silking. Whereas tester T3 showed maximum mean values for grain yield per plant, harvest index, oil content and protein content and minimum mean values for days to 50 per cent tasseling and days to 50 per cent silking. Hybrid L12 xT3 showed maximum mean values for grain yield per plant and harvest index.en_US
