With an objective to identify potential parents and hybrids for quality and other traits for maize improve¬ment, an investigation was carried out with diallel analysis involving Eight lines I-07-59-5 [P1], I-07-6-4-4 [P2], I-07-9-3-1[P3], I-07-11-3-3[P4], I-07-65-18-3 [P5], I-07-65-13-1[P6], I-07-13-1-3 [P7] and I-07-7-1-1[P8].These eight parents and their 28 F1 hybrids along with check hybrid HQPM-1 were evaluated in randomized block design with three replications. The high relative heterosis and heterobeltiosis value was observed for protein, lysine in protein, and tryptophan in protein. The highest positive significant heterosis at all the three levels was exhibited by the F1 hybrid P2 x P5. This hybrid also revealed highest per se performance for protein content [8.64%], lysine in protein [3.23] and tryptophan in protein [0.66].
