A study was undertaken to investigate the heterosis and inbreeding depression in 21 hybrids (F1) and their F2s produced by crossing seven maize inbreeds in all possible combinations, excluding reciprocal. The crosses VL-1016556 × CML-171 and VL-1016556 × KL-153237 were identified as the best F1s as they showed superiority for grain yield per plant over the check. The highest heterobeltiosis (Hb) was recorded by hybrids VL-1016556 × KL-153237 and VL-1016556 × CML-171 while hybrids VL-1016556 × KL-153237 and VL-1016556 × CML-171 exhibited the highest economic heterosis (Hc). Keeping the greater magnitude of heterosis, high mean performance and lesser inbreeding depression (less than 15%) into consideration, five crosses, namely, VL-1016556 × BHU-N5, VL-1016556 × CML-171, VL-1016556 × CML-161, CML-171 × BHU-N5 and VL-1016556 × BHU QPM-3 were identified as best hybrids.
