High-yielding adapted maize varieties which can resist the maize streak virus are being introduced into national research programmes in Africa. This is the result of a joint plant-breeding effort involving the International Centre for Maize and Wheat Improvement (CIMMYT) in Mexico and the International Institute of Tropical Agriculture (IITA) in Nigeria. Streak virus disease is amongst the most serious affecting maize in sub-Saharan Africa. The virus is transmitted by leafhoppers, whose population is influenced by weather and the availability of alternative hosts. Yield losses consequently vary from season to season In the mid-1970's, CIMMYT scientists found resistance to maize streak virus in three different maize populations. Researchers have since made rapid progress in producing adapted, streak resistant germplasm for African national programmes. Some of the varieties produced have been released to farmers in Benin and Togo, and tests are being done on farms in a number of other countries. Work is continuing to strengthen resistance to the disease in high-yield varieties. Within a few years, it is expected that all the maize populations which are important for Africa will have strong resistance.
