| Sumario: | This chapter focuses on quantitative genetics, screening of germplasm collection at the International Institute of Tropical Agriculture, genetic diversity, genetic variation of provitamin A content in maize. Inheritance, heritability, genotype-by-environment for carotenoid content, population improvement, development of open-pollinated varieties were also discussed. Agronomic performance, stress tolerance, combining ability, heterosis were also conducted in sub-Saharan Africa. It may be concluded that maize in sub-Saharan Africa can be effectively subjected to genetic enhancement of provitamin A, along with other mineral components of the kernel and the plant traits for sustainable, high-quality food sufficiency to drastically reduce hunger and malnutrition.
