Heterotic grouping of maize inbred lines on the yield basis of combining ability: Efficiencies and prospects

Abstract

Founding the perfect fit of inbreds into heterotic groups is a pivotal to the development of triumphant maize hybrids. Here the objective of this study were to (i) classifying inbred line(s) into known heterotic groups with unknown testers, HGCAMT, SCA-GY and HSGCA methods (ii) analyze breeding efficiencies of this method(s) and (iii) future prospects of heterotic grouping research. These results demonstrate the usefulness of combining ability in classifying inbreds into useful heterotic group(s) for further studies.
