“…Biofortification is one of the alternative approaches to overcome the problem of malnutrition and hidden hunger across the world (Kaur et al 2019). Biofortification can contribute significantly towards reducing the burden of micronutrient deficiencies in the poor and underprivileged people in a highly costefficient manner (Meenakshi et al 2010;Kumar et al 2016).…”

Micronutrient malnutrition is one of the major health problem, especially iron (Fe) and zinc (Zn) deficiencies that are widespread coupled with inadequate food supply in the developing world. Pearl millet grains are a good source of Fe and Zn elements making it a potential staple crop for overcoming hidden-hunger and micronutrient deficiencies. Breeding pearl millet with high levels of grain Zn and Fe contents represents a major opportunity to enhance the intake of these minerals for poor and malnourished people. A precise understanding of the genetic variability, correlation of mineral nutrients, genotype × environment (G × E) interaction is important for developing improved lines with high Fe and Zn content. To get fair estimates, we used a bi-parental recombinant inbred lines (RIL) mapping population representing F2 phenotypic variance. A total of 317 RILs were evaluated for grain iron and zinc content in two seasons, Summer 2016 (E1) and Summer 2017 (E2). The result from the analysis of variance exhibited a large variability for grain Fe and Zn content across the two environments. The G × E for high grain Fe were significant at P 0.01. The mean performance across the two environments data for grain Fe ranged from 22.9 to 154.5 mg kg-1 (ppm) and Zn content ranged from 19.3 to 121 mg kg-1. The correlation coefficient for grain Fe and Zn was 0.9, and 0.8 and across the two (E1 and E2) environments. The value of correlation coefficient (0.9) was found to be highly significant at P 0.01 level, that indicated good opportunities for simultaneous genetic improvement of both iron and zinc contents in pearl millet.

“…Plant breeding techniques are used in the biofortification approach to develop staple food crops with greater micronutrient content ( 97 ), this assists to target low-income households in the country. Numerous crops have been targeted for biofortification through crop breeding due to their improved acceptance ( Table 6 ).…”

Micronutrient deficiency also known as “hidden hunger” refers to a condition that occurs when the body lacks essential vitamins and minerals that are required in small amounts for proper growth, development and overall health. These deficiencies are particularly common in developing countries, where a lack of access to a varied and nutritious diet makes it difficult for people to get the micronutrients they need. Micronutrient supplementation has been a topic of interest, especially during the Covid-19 pandemic, due to its potential role in supporting immune function and overall health. Iron (Fe), zinc (Zn), iodine (I), and selenium (Se) deficiency in humans are significant food-related issues worldwide. Biofortification is a sustainable strategy that has been developed to address micronutrient deficiencies by increasing the levels of essential vitamins and minerals in staple crops that are widely consumed by people in affected communities. There are a number of agricultural techniques for biofortification, including selective breeding of crops to have higher levels of specific nutrients, agronomic approach using fertilizers and other inputs to increase nutrient uptake by crops and transgenic approach. The agronomic approach offers a temporary but speedy solution while the genetic approach (breeding and transgenic) is the long-term solution but requires time to develop a nutrient-rich variety.

“…Several studies have established that Fe is mostly localized in embryo and aleurone layer and very less Fe is distributed in the endosperm (Kaur et al 2019;Kyriacou et al 2014;Choi et al 2007;Promu-thai et al 2003). Conversely, a significant concentration of Zn is localized in endosperm and retained even after polishing.…”

We evaluated a set of 190 genotypes for five grain-nutrient, five grain physico-chemical quality and four derived traits. Wide variability was observed for all the traits studied, with CV ranging from 9.33 to 51.89%. No correlation was observed between grain nutritional and physico-chemical quality traits. Iron (Fe) and Zinc (Zn) content in brown rice showed significant positive correlation. Zn content in brown and polished rice showed significant association however, the Fe content in brown and polished rice did not show significant association. Two principal components each in grain nutritional and physico-chemical traits explained 73.15 % and 62.82 % of the total variation, respectively. Cluster analysis grouped the accessions into two and three clusters on the basis of grain physico-chemical traits and nutritional traits, respectively. The study has led to the identification of promising donors for biofortification and grain quality improvement in rice.
