Quality protein maize (QPM) represents an excellent technological intervention, which contains twice the amount of lysine and tryptophan as normal maize. The recent discovery of two key genes influencing grain carotenoid composition has enabled increasing the beta carotene content of yellow maize two- to tenfold in the tropical germplasm. A number of scientific advances have been made in understanding the phytate metabolic pathway in maize, which appears promising for product development in the future. The biofortification objectives in maize are likely to evolve further as new targets such as antioxidant and prebiotic content and bioavailability emerge relevant to the target sub-populations.Collection: CIMMYT Staff Publications Collection
