This project aims to enhance the gene editing (GE) toolbox specifically for pearl millet and apply it to target genes linked to rancid off-flavour—a key barrier to the grain’s wider adoption. By developing efficient GE tools for this crop, the project will not only address rancidity but also open pathways for rapid genetic improvements in pearl millet and related traits.
Pearl millet is a climate-resilient, drought-tolerant grain rich in iron, zinc, and low glycaemic index starch making it a valuable staple across Africa and Asia. However, its flour has a short shelf-life, often turning rancid within weeks. While the genes responsible for rancidity have been identified, progress in addressing them has been slow due to limited gene editing efficiency in this crop.
With India recently lifting the regulatory ban on gene-edited crops (SDN1 and SDN2), ICRISAT is now positioned to introduce and field-test GE variants within its breeding programs. Building on its 50-year legacy of supporting smallholder farmers in challenging environments, and its proven success in developing GE protocols for other crops, ICRISAT is uniquely placed to lead this innovation in pearl millet improvement.
