Dr. Baffour Badu-Apraku is a Principal Scientist, Maize Breeder and Quantitative Geneticist at the International Institute of Tropical Agriculture (IITA). He has over thirty years of experience in agricultural research, development, and management in West and Central Africa. His major areas of focus include breeding, testing, and promotion of technology transfer especially the adoption of open-pollinated and hybrid varieties of normal endosperm maize, Quality Protein Maize, Pro-vitamin A and sustainable agronomic practices as well as seed production. Through his maize breeding program at IITA, several Striga-resistant, low soil nitrogen and drought-tolerant early and extra-early populations have been developed and are serving as invaluable sources of varieties and inbred lines for breeders of the sub region. Over the years, many early and extra-early Striga, drought and low soil nitrogen-tolerant varieties and hybrids have been developed in his program, formally released, and widely adopted by farmers in the sub region. The availability of the early and extra-early varieties and hybrids have created niches for maize production, consumption and improved food security in WCA.



Dr. M.A.B. Fakorede is a Professor at the Crop Production and Protection Department of Obafemi Awolowo University, Nigeria. He obtained his B.S. (Agric.) from the University of Ife (now Obafemi Awolowo University) in 1971, and M.S. (1975) and Ph.D (1977) from Iowa State University, USA.  He is a Specialist in Plant Breeding, Quantitative Genetics, and Seed Production, with a strong minor in Agroclimatology. He has over 40 years of research and teaching experience and has served as Collaborating Scientist at IITA as well as Consultant and Training Resource Person in several international agricultural research centers. In collaboration with maize breeders in Nigeria and IITA, he has released several open-pollinated varieties, inbred lines and hybrids. He
