Micronutrient deficiencies, particularly in iron (Fe) and zinc (Zn), remain among the most serious global public health concerns, especially in developing countries where populations rely heavily on a limited number of staple foods (Bouis & Saltzman, 2017; FAO et al., 2020). Iron deficiency is the leading cause of anemia, affecting nearly 30% of the global population, while zinc deficiency compromises immune function, increases susceptibility to infectious diseases, and contributes to stunted growth in children (WHO, 2020; Prasad, 2013). To address these challenges, sustainable food-based strategies such as the biofortification of staple crops are increasingly prioritized as long-term solutions to combat hidden hunger. The considerable genetic diversity present in rice (Oryza spp.) provides valuable opportunities to identify nutrient-dense genotypes for direct consumption or use in breeding programs targeting improved nutritional quality. In unpolished brown rice, Fe concentrations typically range from 6.9 to 22.3 mg/kg, while Zn concentrations vary between 14.5 and 35.3 mg/kg (Maganti et al., 2020). Using X-ray fluorescence (XRF) spectroscopy, we analyzed the nutritional profiles of 700 accessions from the minicore collections of Oryza glaberrima and Oryza sativa. Our results identified 18 iron- and zinc-rich accessions (11 O. glaberrima and 7 O. sativa) with Fe concentrations ranging from 23 to 35.5 mg/kg and Zn concentrations from 30 to 37 mg/kg in unpolished grains. These dual-nutrient-rich accessions represent promising candidates for the development of biofortified rice varieties adapted to African agro-ecological zones and addressing key nutritional deficiencies.
