Millets are recognized for their climate resilience, which encompasses their ability to adapt to various ecological conditions, low vulnerability to environmental stresses, reduced irrigation requirements, improved growth and productivity in low-nutrient environments, and diminished reliance on external inputs. Being C4 grasses, millets have exceptional heat and drought resistance, a characteristic that makes them vital for food and fodder security in the dry and semiarid tropics. Millet grains hold medicinal importance, in addition to their fundamental nutritional value. These grains possess a variety of health-promoting bioactive phytochemicals, serving as a remarkable option for eliminating nutritional deficiencies and hidden hunger. The crop improvement of millet crops via genetic, agronomic, and technological innovations guarantees sustainability and climate resilience. Supplementing traditional breeding programs with molecular tools will address the yield constraints effectively and place the resistance genes in high-yielding and adaptable backgrounds making these crops more sustainable. The recent advancements in molecular breeding have brought in several options for a plant breeder to choose the need-based protocols to bring in the desired changes in a shorter period of time to attain the ultimate goal of food security, promoting sustainable agriculture and fostering economic stability in lieu of climate change.
