Present study was aimed to assess the general combining ability effects of parents and specific combining ability effects of hybrids for yield and yield related traits and explore their use in hybrid development. Combining ability analysis using line x tester design was conducted in maize (Zea mays L.) inbred lines by growing 45 F₁’s generated by crossing fifteen lines with three well adapted testers. There was a great contribution of lines towards σ² gca for all the traits. Inbred lines viz., KDM 334, KDM 342 and KDM 347 were good combiners for yield and yield attributing characters. Tester C6 was high combiner for grain yield, number of kernel rows ear^-1 and number of kernels row^-1. Among the hybrids, KDM 331 x super-1, KDM-333 x KDM-34, KDM 342 x C6, KDM331 x KDM-346 and KDM 336 x KDM-346 exhibited highest significant sca effects for yield and yield attributing traits.
