Abstract

Climate change has posed irreversible changes that challenge agriculture. The increased incidence of biotic and abiotic stresses has severely impacted agriculture, leading to poor yield and productivity of the major staple cereals like rice and wheat. This impact has increased hidden hunger, malnutrition, and poverty. Additionally, the cultivation of these staples requires higher resource input than the yield obtained in return. Nevertheless, neglected and underutilised cereals like millets are climate resilient, stress-tolerant, farmer-friendly, low input, high biomass, and abundantly rich with nutritional and nutraceutical properties. Declaration of the year 2023 as the “International Year of Millets” has highlighted the potential role that millets can play in combating climate change and hidden hunger, thereby streamlining the research focus towards understanding them better. One of the small millets, kodo millet (Paspalum scrobiculatum), popularly grown and cultivated in India, has high nutritional, micronutrient, and antioxidant properties and holds the potential to address nutritional security. The crop, also grown in high-altitude regions, showcases vast genetic diversity, and the availability of diverse germplasm collection aids in deciphering the molecular regulations to produce improved cultivars. However, due to limited genetic resources and the unavailability of genome sequence, little success has been achieved in exploiting the important traits of this crop. The chapter aims to summarise the research status of the crop and genetic resources developed so far. Additionally, it highlights the future perspective of integrating conventional breeding approaches with novel omics approaches and gene editing techniques to trigger the crop improvement programmes for this crop.
