Combining ability studies for grain yield and quality parameters in quality protein maize (qpm) (Zea mays l.) inbred line crosses Shanthi P., Satyanarayana E., Babu G. Suresh, Kumar R. Sai Department of Genetics and Plant Breeding, Allahabad Agriculture Institute Deemed University, Allahabad-211 007, Uttar Pradesh, India Online published on 19 March, 2018. Abstract Combining ability studies using 10 x 10 diallel set (excluding reciprocals) were carried out at two locations (Hyderabad and Allahabad) and in two seasons (kharif 2003 and 2004) for grain yield and three quality parameters viz. protein content, oil content and tryptophan content. From this study, it was inferred that out of 45 hybrids studied, the cross combinations viz, P4 x P7, P5, x P10 P2, x P6, P3, x P5, P3, x P9. and P1, x P5. were found as good specific combiners for grain yield alongwith protein, oil and tryptophan content. Among the 10 parents, the parents P4 and P1 were found to be the best parents for grain yield, while the parents P4, P1. and P2, for protein, oil and tryptophan content.
