In 2017, 79 improved maize varieties were released by the CRP MAIZE partners worldwide, including 26 in Latin America, 44 in Sub-Saharan Africa and 9 in Asia. These varieties are based on use of CGIAR lines from CIMMYT and the International Institute of Tropical Agriculture (IITA). Some of the special traits stacked in these varieties include drought and heat tolerance, nitrogen use efficiency, enhanced protein quality, high kernel zinc and resistance to diseases of regional or global importance, such as maize lethal necrosis (MLN), tar spot complex (TSC), and resistance to the parasitic weed, Striga. MAIZE worked with partners to control the spread of Fall Armyworm in Africa.
