“…Per capita consumption of maize is 290 g/day in women and 170 g/day in children of 4–6 years in the African countries where maize is consumed as staple food crop ( reviewed in Andersson, Saltzman, Virk, & Pfeiffer ). Therefore, it could be inferred that based on the kernel zinc variability and per capita consumption of maize, this is suitable crop for zinc biofortification.…”

“…CIMMYT is working with MAIZE programme and HarvestPlus of CGIAR to develop and deploy the maize biofortification. Currently, more than 40 provitamin A biofortified maize genotypes including open pollinated varieties and hybrids have been released in different African countries (reviewed in Andersson et al., ). Several promising varieties having more than the targeted provitamin A contents are being evaluated across the sub‐Saharan Africa to be released by 2018.…”

“…Zn contents range from 17 to 42 ppm among the tested genotypes, whereas elite tropical maize genotypes having more than 80% of target Zn contents are also identified. Zn‐enriched maize genotypes are also being tested for agronomic performance across several African and Latin American countries (reviewed in Andersson et al., ).…”

Zn deficiency is one of the leading health problems in children and women of developing countries. Different interventions could be used to overcome malnutrition, but biofortification is most impactful, convenient, sustainable and acceptable intervention. Maize is one of the major crops grown and consumed in the regions with prevalent Zn malnutrition; therefore, this is suitable target for Zn biofortification. Zn biofortification of maize could be achieved through agronomic and genetic approaches. Discussion of agronomic approaches with genetic approaches is prerequisite because soils in developing countries are deficit of Zn and availability of Zn in soils is mandatory for estimating the genetic responses of maize genotypes through genetic approaches. Seed priming, foliar and soil applications are agronomic tools for biofortification, but solo and combined applications of these treatments have different effects on Zn enrichment. Genetic approaches include the increase of Zn bioavailability or increase of kernel Zn concentration. Zn bioavailability could be increased by reducing the anti‐nutritional factors or by increasing the bioavailability enhancers. Kernel Zn concentration could be improved through hybridization and selections, whereas genetically engineered attempts for improving Zn uptake from soil, loading in xylem, remobilization in grains and sequestration in endosperm can further improve the kernel Zn concentration. Key challenges associated with dissemination of Zn biofortified maize are also under discussion in this draft. Current review emphasized all of above‐mentioned contents to provide roadmap for the development of Zn biofortified maize genotypes to curb the global Zn malnutrition.

“…Varieties of biofortified cassava with higher pVACs content (target level of 15 µg g −1 β CE) are being developed by the Institut National pour l'Etude et la Recherche Agronomiques (INERA) in the DRC and the Nigerian National Root Crops Research Institute in Nigeria. The pVACs target level for cassava, set to reach 50% of the estimated average requirement (EAR) for children and pregnant women in the DRC and Nigeria, assumes that up to 50% of pVACs in peeled roots is lost during processing, storage, and cooking …”

The results indicated that biofortified boiled cassava could be an effective food product to improve pVACs intake in areas where vitamin A deficiency exists, and processing of chikwangue and fufu should be improved before promoting biofortified cassava in vitamin-A-deficient areas with high cassava consumption. © 2018 The Authors.

“…Bio-fortification is relatively a new technology, which is being promoted worldwide to combat hidden hunger (undernutrition), which is as a result of most communities relying on staple foods, which lack some nutrients resulting in increased incidence of malnutrition (Machida et al, 2014). It has been scientifically reported that bio-fortification is feasible without compromising agronomic productivity for crops such as maize; with high protein quality and vitamin A, that is QPM and pro-vitamin A maize, respectively (Andersson et al, 2017;Covic et al, 2017;Potrykus, 2017); hence bio-fortification is the way to go. Bio-fortified crops such as QPM have been developed to fight the problem of PEU in maize dependent communities such as the SSA.…”
