Genetic architecture of Grain Iron and Zinc densities and their association with Agronomic traits in Pearl Millet (Pennisetum glaucum (L.) R. Br.)

Micronutrient malnutrition resulting from dietary deficiency of one or more micronutrients has been recognized as a serious human health problem worldwide. The most striking of these are iron (Fe) and zinc (Zn) deficiencies that rank 9th and 11th, respectively, among the top 20 risk factors contributing to global burden of disease. Biofortification is a cost-effective and sustainable agricultural strategy to address the micronutrient deficiencies of resource-poor and majority of malnourished populations. In a recent initiative, research is underway to improve Fe and Zn densities in pearl millet. The main objective of the research reported herein was to study the genetics of Fe and Zn densities and their association with grain yield with a view to enhance breeding efficiency and devise effective breeding strategies for the development of improved cultivars with elevated levels of these micronutrient
