52Zinc (Zn) deficiency is a major risk factor for human health, affecting about 30% of the 53 world's population. To study the potential of genomic selection (GS) for maize with increased 54 Zn concentration, an association panel and two doubled haploid (DH) populations were 55 evaluated in three environments. Three genomic prediction models, M (M1: Environment + 56 Line, M2: Environment + Line + Genomic, and M3: Environment + Line + Genomic + Genomic 57 x Environment) incorporating main effects (lines and genomic) and the interaction between 58 genomic and environment (G x E) were assessed to estimate the prediction ability (rMP) for each 59 model. Two distinct cross-validation (CV) schemes simulating two genomic prediction breeding 60 scenarios were used. CV1 predicts the performance of newly developed lines, whereas CV2 61 predicts the performance of lines tested in sparse multi-location trials. Predictions for Zn in CV1 62 ranged from -0.01 to 0.56 for DH1, 0.04 to 0.50 for DH2 and -0.001 to 0.47 for the association 63 panel. For CV2, rMP values ranged from 0.67 to 0.71 for DH1, 0.40 to 0.56 for DH2 and 0.64 to 64 0.72 for the association panel. The genomic prediction model which included G x E had the 65 highest average rMP for both CV1 (0.39 and 0.44) and CV2 (0.71 and 0.51) for the association 66 panel and DH2 population, respectively. These results suggest that GS has potential to accelerate 67 breeding for enhanced kernel Zn concentration by facilitating selection of superior genotypes. 68 69 93 2015; Manickavelu et al. 2017; Arojju et al. 2019). 94The utility and effectiveness of GS has been examined for many different crop species, 95 marker densities, traits and statistical models and varying levels of prediction accuracy have been 96 achieved (de los Campos et al.

“…Similar to VAD, iron deficiency anemia (IDA) commonly affects preschool age children and women [18,19]. Consequently, iron deficiency anemia is linked to maternal and perinatal mortality, and impairment of cognitive skills and physical activity [18][19][20][21]. Unfortunately, IDA is disproportionately prevalent in South Asia and Africa where 43% and 37%, respectively, of maternal mortality are attributed to IDA [19].…”

Addressing vitamin and mineral status of communities has presented challenges to governments and health experts across the globe. These nutrient deficiencies are commonly referred to as 'hidden hunger' because their symptoms are not visible to the naked eye. Dietary diversity, food fortification and micronutrient supplementation are the three main strategies used for addressing this problem. Because most people in developing countries rely on plant-based diets, biofortification presents an opportunity for addressing vitamin and mineral deficiencies. Although fortification and supplementation are effective in specific target populations, biofortification increases food nutritional value in the dietary diversity option. Supplementation is expensive and requires linkages with health programs such as polio immunization to minimize costs. Food biofortification requires not only laboratories but other facilities to carry out the process. Food fortification also requires a well-equipped laboratory to monitor quality at the factory level and ensure product success in the market. While biofortification is expensive in the beginning, it is more cost-effective and stable in the long run. Supplementation has been done in partnership with UNICEF for iron and folic acid for expectant mothers, as well as vitamin A supplementation for children aged 6-59 months and lactating mothers. Calcium supplementation is also done in some countries for pregnant women. Food fortification is done to edible oils (vitamin A), grain flour (maize and wheat) and complementary foods. Fortification of edible oils with vitamin A and fortification of flour with iron and other micronutrients has been mandatory in Kenya since 2012. Additionally, the Ministry of Health (MoH) developed guidelines for homebased fortification (sprinkles) in 2014/2015. Micronutrient supplementation and food fortification have achieved varied degrees of success in Kenya according to the 2011 National Micronutrient Survey. Biofortification may provide considerable amounts of readily bioavailable micronutrients. As outlined in this paper, biofortification offers a fresh approach to addressing vitamin and mineral deficiencies mainly due to affordability and accessibility. Although salt iodization is mandatory at 30-50 mg/kg, less than 50% of the salt manufacturers have complied with these requirements, indicating the complexities of food fortification.
