Micronutrient deficiency, particularly iron and zinc deficiency, is a major public health concern and remains one of the most pressing challenges to food and nutrition security, especially in developing countries (Bouis & Saltzman, 2017; FAO, 2020). There is increasing recognition of the need for sustainable, food-based strategies such as biofortification to combat hidden hunger. The wide genetic diversity present in plant genetic resources offers a valuable opportunity to identify micronutrient-rich genotypes for direct utilization or for use in breeding programs aimed at enhancing the nutritional quality of staple crops. In rice (Oryza sativa), iron concentration in unpolished grains typically ranges from 6.9 to 22.3 mg/kg (Maganti et al., 2020). Using X-ray fluorescence (XRF) spectroscopy, we assessed the nutritional composition of 700 accessions from the minicore collections of Oryza glaberrima and Oryza sativa. Our results revealed 100 iron-rich accessions (62 O. glaberrima and 38 O. sativa) with unpolished grain iron concentrations ranging from 23 to 89 mg/kg. These high-iron genotypes represent promising candidates for developing biofortified rice varieties adapted to African agro-ecologies.
