The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and yield related traits. Eight inbred lines were crossed with three testers using line × tester mating design. The resulting twenty-four crosses along with eleven parents were evaluated at two locations during Kharif 2015 in a complete randomized block design. The parent KDM-445A was identified as best combiner for grain yield plant-1 followed by CM-502 and KDM-347. Besides, KDM-445A was also accompanied with significant and desirable gca for 100 grain weight, grain depth, shelling percentage, protein content, number of kernels row-1, days to 50 per cent tasseling and days to 50 per cent silking. Among the crosses, KDM-347 × SMC-7, KDM-445A × DMR-N6 and V-351 × DMR-N6 exhibited highly significant and desirable SCA effects for grain yield plant-1. Therefore, these crosses can be utilized for developing high yielding hybrid varieties in maize.
