Through his maize breeding program at IITA since 1992, several Striga-resistant and drought-tolerant early and extra-early populations have been developed and are serving as valuable sources of varieties and inbred lines for breeders of the subregion. Over the years, many early and extra-early Striga, drought and low soil nitrogen-tolerant varieties and more recently hybrids have been developed in his program, formally released, and widely adopted by farmers in the subregion. He has also conducted research to improve maize selection and evaluation procedures including breeding for resistance to multiple stresses, identification of indirect selection criteria, and grouping of evaluation sites into mega-environments using the GGE biplot analysis of genotype × trait interaction and factor analysis of repeatability estimates. Dr Badu-Apraku’s most recent achievement includes the development of Striga-resistant and low soil nitrogen-tolerant extra-early varieties and hybrids with genes for tolerance to drought at the flowering and grain-filling periods.
