To effectively use male–sterility inducing cytoplasm, it is necessary to identify restorers and lines that are suitable for conversion to male sterile lines. Progressive research has been done on sorghum landraces in Nigeria ranging from breeding for resistance to diseases, to the development of open pollinated varieties, however, little work has been done to determine heterotic groups and identification of good parental lines among sorghum landraces. Although commercially viable sorghum hybrids for West and Central Africa (WCA) are just now available, it is only suited for a single maturity band (100km north-south latitude) for the Guinea-race zone of Senegal, Mali and Burkina Faso, but not available for the drier (further North) zones of Nigeria, which grow mostly the caudatum or durra type.
