Twelve inbred lines were crossed with each of five testers in a line × tester design to evaluate combining ability and heterosis to identify promising hybrids of maize for various quality parameters like protein, tryptophan, lysine, starch contents and grain yield. The analysis of variance revealed highly significant differences for all the traits reflecting adequate diversity in the genetic material chosen for the study. Significant differences among the genotypes for quality attributes such as protein, tryptophan, lysine and starch contents were observed. The cross combination, BQPM-2 × BAUIM-2 (21.54) showed highest magnitude of economic heterosis over the best check HQPM-1 for protein content whereas for tryptophan, lysine contents and starch contents BQPM-2 × BAUIM-2 showed highest magnitude of economic heterosis as 5.56. 5.47 and 5.89 respectively over the best check HQPM-1. Hemavathy and Balaji (2008)  suggested that the exploitation of heterosis is the best method to increase the qualitative traits like lysine, tryptophan along with increase in the grain yield in maize. These promising crosses with good yield along with good quality parameters can be tested extensively over environments in the future and can be utilized as good performers profitably by the maize breeders.
