Abstract This chapter discusses the importance of multi-environment trials (METs) in new crop cultivar release and recommendation. The problems posed by differential genotype responses in different environments (genotype environment interactions) in cultivar evaluation are discussed and improvements in the methods used for MET data analysis are presented. The rationale and applications of the GGE-biplot methodology in MET data analysis are also pointed out.

Abstract This chapter enumerates historical developments in genetics up to the 21st century, starting from Mendelism, the rise of Drosophila and cytogenetics to mutation, non-nuclear inheritance, pleiotropy and transformation. The future of genetics is mentioned, indicating that the role of quantitative genetics and genomics in basic biology and applied sciences, including crop improvement, will increase greatly in the 21st century.

Abstract 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.
