Prasanna Global Maize Program & CGIAR Research Program MAIZE, International Maize and Wheat Improvement Center (CIMMYT), Nairobi, Kenya Email: [email protected] Introduction Maize is cultivated on more than 180 million hectares (M ha) globally, contributing ~50% (1,170 million metric tons or MMT) to the global grain production. About 60-70 per cent of the cultivated area under maize is in the developing world, with a predominant proportion in the low- and lower-middle income countries. The crop provides over 20% of total calories
