The northern leaf blight disease occurrence, intensity, distribution and resurgence in Tanzania have signalled attention to maize breeders. A clear understanding of its disease genetics, mode of gene actions and heritability plays significant roles in the successful designing breeding strategies and control. Gene actions and heritability provides information on choosing the appropriate breeding methods to be employed.  Therefore, this review aimed at bridging the disease genetics information and the practical application of breeding methods to be employed by breeders in fields. Information gathered here are important tools to breeders for selection of the best breeding methods that are used to impart resistance to northern leaf blight disease in maize.
