Determination of heterosis in maize hybrids is necessary for their commercial exploitation. Therefore, this study was conducted to estimate the amount of standard heterosis of the hybrids for yield and yield-related traits. The experimental material comprised twenty-eight F1 hybrids along with two standard checks (BHQPY 545 and MH 138) were evaluated using Alpha-Lattice Design with three replications during 2018 main cropping season at Haramaya University Research Site (Raare). The highest percentage of standard heterosis for grain yield was retained from the crosses L3ŚL6 (20.58%), L3ŚL8 (7.65%), over BHQPY 545 and L3ŚL6 (49.20%), L3ŚL8 (33.20%), over MH138, indicating these hybrids superior for commercial cultivation. Maximum standard heterosis was recorded for L3 Ś L6 (25.75%), L1 Ś L4 (16.99%) and L3 ŚL6 (37.82%) for 1000 kernel weight, number of kernels per row and biomass yield, respectively over BHQPY-545, and L3 Ś L6 (54.79%), L1 Ś L4 (16.90%) and L3 ŚL6 (48.90%), for 1000 kernel weight, number of kernels per row and biomass yield, respectively over MH-138.
