“…Hence, to start with, a breeding program was initiated in the International Maize and Wheat Improvement Center (CIMMYT). In particular, two key nurseries, namely, HarvestPlus Advanced (HPAN) and HarvestPlus Yield Trial (HPYT), bred at CIMMYT are routinely shared with NARS in India and Pakistan for varietal development (Virk et al, 2021 ). These nurseries are field-evaluated at multiple locations to shortlist candidate varieties possessing >6 ppm additional Zn concentration.…”

“…Recently, sharing of early-generation segregating materials (F4/F5) has also been started for the fast-track development of locally adapted varieties for high Zn. The new varieties have 100% target increment for grain Zn concentration (37 ppm) and are agronomically at par with or superior to the popular wheat cultivars of South Asia (e.g., Zincol-2016 and Akbar-2019), indicating that there is no yield trade-off (Velu et al, 2012 , 2015 , 2021 ; Virk et al, 2021 ). The incorporation of resistance to major diseases, such as yellow rust and stem rust (Ug99), was also built into zinc wheat.…”

Biofortification breeding for three important micronutrients for human health, namely, iron (Fe), zinc (Zn), and provitamin A (PVA), has gained momentum in recent years. HarvestPlus, along with its global consortium partners, enhances Fe, Zn, and PVA in staple crops. The strategic and applied research by HarvestPlus is driven by product-based impact pathway that integrates crop breeding, nutrition research, impact assessment, advocacy, and communication to implement country-specific crop delivery plans. Targeted breeding has resulted in 393 biofortified crop varieties by the end of 2020, which have been released or are in testing in 63 countries, potentially benefitting more than 48 million people. Nevertheless, to reach more than a billion people by 2030, future breeding lines that are being distributed by Consultative Group on International Agricultural Research (CGIAR) centers and submitted by National Agricultural Research System (NARS) to varietal release committees should be biofortified. It is envisaged that the mainstreaming of biofortification traits will be driven by high-throughput micronutrient phenotyping, genomic selection coupled with speed breeding for accelerating genetic gains. It is noteworthy that targeted breeding gradually leads to mainstreaming, as the latter capitalizes on the progress made in the former. Efficacy studies have revealed the nutritional significance of Fe, Zn, and PVA biofortified varieties over non-biofortified ones. Mainstreaming will ensure the integration of biofortified traits into competitive varieties and hybrids developed by private and public sectors. The mainstreaming strategy has just been initiated in select CGIAR centers, namely, International Maize and Wheat Improvement Center (CIMMYT), International Rice Research Institute (IRRI), International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), International Institute of Tropical Agriculture (IITA), and International Center for Tropical Agriculture (CIAT). This review will present the key successes of targeted breeding and its relevance to the mainstreaming approaches to achieve scaling of biofortification to billions sustainably.

“…To combat MNDs, biofortification stands as a cost-effective and widely endorsed solution. Expanding biofortification efforts in wheat, a key dietary staple, necessitates a robust policy framework for coordinated implementation among stakeholders ( 94 ). Firstly, it is imperative to bolster research and development (R&D) organizations engaged in wheat biofortification through increased investment.…”

“…Firstly, it is imperative to bolster research and development (R&D) organizations engaged in wheat biofortification through increased investment. These efforts should seamlessly integrate with breeding programs, either at the regional or national level ( 94 , 95 ). Concurrently, rigorous, evidence-based impact assessments must be conducted to elucidate the potential benefits of biofortification.…”

Addressing global hidden hunger, particularly in women of childbearing age and children under five, presents a significant challenge, with a focus on iron (Fe) and zinc (Zn) deficiency. Wheat, a staple crop in the developing world, is crucial for addressing this issue through biofortification efforts. While extensive research has explored various approaches to enhance Fe and Zn content in wheat, there remains a scarcity of comprehensive data on their bioavailability and impact on human and animal health. This systematic review examines the latest trends in wheat biofortification approaches, assesses bioavailability, evaluates the effects of biofortified wheat on health outcomes in humans and animals, and analyzes global policy frameworks. Additionally, a meta-analysis of per capita daily Fe and Zn intake from average wheat consumption was conducted. Notably, breeding-based approaches have led to the release of 40 biofortified wheat varieties for commercial cultivation in India, Pakistan, Bangladesh, Mexico, Bolivia, and Nepal, but this progress has overlooked Africa, a particularly vulnerable continent. Despite these advancements, there is a critical need for large-scale systematic investigations into the nutritional impact of biofortified wheat, indicating a crucial area for future research. This article can serve as a valuable resource for multidisciplinary researchers engaged in wheat biofortification, aiding in the refinement of ongoing and future strategies to achieve the Sustainable Development Goal of eradicating hunger and malnutrition by 2030.
