Thirty inbred lines were crossed with each of three testers in a line × tester design to evaluate combiningability and heterosis to identify promising hybrids of maize for various characters viz., days to 50 per cent tasseling, daysto 50 per cent silking, days to 75 per cent dry husk, ear length, ear girth, number of kernels row per ear, number of kernelper row, hundred seed weight, shelling percentage and grain yield per hectare. The resulting F1’s along with three checks andthe parents were evaluated during summer 2013. Analysis of variance revealed highly significant differences among thegenotypes. Crosses excelled their perspective parents in performance for most of the traits studied. DMIL767, DMIL318and DMIL326 among the parental lines and DMIL011 among the testers were identified as the best general combiner forgrain yield. Whereas among the hybrids, DMIL765 x DMIL031, DMIL318 x DMIL011 and DMIL639 x DMIL011were identified as a potential cross combination for grain yield while the cross DMIL765 x DMIL031 recorded highestmagnitude of economic heterosis of 13.95 percentages over the best standard check. So the crosses DMIL765 x DMIL031,DMIL318 x DMIL011 and DMIL639 x DMIL011 can be utilized for developing high yielding hybrid varieties as well as forexploiting hybrid vigor.
