A leafhopper transmitted virus, native to Africa, that causes characteristic pale chlorotic streaks along the veins of maize leaves and can cause complete crop failure in severe early infections. It is the most economically important virus disease of maize in Africa, where yield losses in susceptible varieties have reached 100 percent in some outbreak years, and it has driven major maize breeding programs for resistance across the continent.

Maize streak virus (MSV) is a virus primarily known for causing maize streak disease (MSD) in its major host, and which also infects over 80 wild and domesticated grasses. It is an insect-transmitted pathogen of maize in the genus Mastrevirus of the family Geminiviridae that is endemic in sub-Saharan Africa and neighbouring Indian Ocean island territories such as Madagascar, Mauritius and La Reunion.

Article text
The development of conventionally resistant maize varieties has been a priority since the 1950s in Kenya, Nigeria, South Africa and elsewhere, with a good deal of success: however, there are several genes associated with resistance, and breeding is complex.
