Abstract:

The experiment comprised of twenty one maize hybrids generated from a 7 X 7 diallel cross, along with their parents and two standard check hybrids (Gujarat Maize 3 and HQPM 1). The analysis of variance revealed that all the characters studied exhibited highly significant genotypic differences. This indicated that experimental material under study had sufficient genetic diversity for different traits among females, males, hybrids and checks. As per the per se performance, for grain yield cross GWL 24 x CML 490 (196.23) having the highest value, while for protein content cross CML 264 x GWL 27 (12.75) were the best. The heterotic hybrid GWL 24 x CML 490 followed by cross CML 264 x GWL 22 registered significant heterosis in desired direction for grain yield. Whereas, the cross CML 264 x GWL 27 followed by CML 186 x GWL 28 registered significant and positive relative heterosis, heterobeltiosis and standard heterosis for protein content. The hybrids GWL 24 x CML 490, CML 264 x GWL 22 and CML 264 x GWL 27 showed high per se performance and higher heterotic effects which could be used to exploit commercially as single cross hybrid or synthetic/composite cultivars.
