ABSTRACT
Twenty one maize hybrids generated from a 7 X 7 diallel cross along with their parents and two standard checks viz., HQPM-1 and Ganga Safed-2 revealed that the cross GYL-7 X PFSR-R2-4 registered significant heterosis over mid parent, better parent and both standard checks for grain yield. The same cross showed significant heterosis for other yield associated traits too. The study emphasized the need to commercially exploit single cross hybrids for their higher heterotic value and economic potential.
Key words :
Diallel crosses, Grain yield, Heterosis, Maize, Starch content.
