Description Malnutrition is a result of one or more micronutrients and vitamins deficiency in the staple diets. Crop biofortification is increasingly recognized as a sustainable breeding strategy to address micronutrients and vitamin deficiency among rapidly growing populations. Pearl millet is a dryland cereal that possesses climate resilience and potentially contributes to the food and nutrition (largely iron and zinc) supply in semi-arid tropics. HarvestPlus supported the pearl millet biofortification programme at ICRISAT assessed the feasibility of iron biofortification in pearl millet and established baseline and breeding targets to achieve the health impact. These targeted breeding efforts accomplished a rapid micronutrient screening lab, pre-breeding, advanced high-iron genetic materials. To date, about 12 biofortified cultivars released for general cultivation in India and West Africa. These cultivars provide > 60% higher Fe than commercial cultivars potentially benefiting millions of people. Several high-Fe seed and restorer parents and more than 1000 high-Fe advanced breeding lines were developed through targeted biofortification breeding and disseminated to public and private sectors through biofortification partnership projects and the HPRC model at ICRISAT. Breeding progress made in achieving the global breeding target of 77 mg/kg of Fe in pearl millet has set the stage for mainstreaming. Rapid screening tool and diagnostic markers encoding the high-Fe (4 SNPs) and drought tolerance (10 SNPs) will enhance the early generation selection and mainstreaming efficacy with stress tolerance in hybrid parents and cultivars breeding pipelines. Bioavailability studies have confirmed that biofortified pearl millet supplies 80% of daily Fe requirements, implying the significance of micronutrient traits in the pearl millet commercial product profiles in India and West Africa.
