Abstract:

Rice (Oryzasativa L.) is one of the most important staple foods for more than half the world’s population and influences the livelihoods and economies of several billion people. Drought stress is the major constraint to rice production and yield stability in rainfed ecosystems. Efforts have been made to identify putative traits, which can confer drought resistance in rice grown under rainfed lowland. However, little progress has been made in incorporating tolerance to abiotic stresses such as drought, since the fundamental mechanisms of drought resistance in rice are poorly understood. Efforts have been made for identifying putative traits encoding different drought resistance traits. The results are being used in marker assisted selection (MAS) for the development of drought resistant varieties. Recent trends in climate change have predicted a further increase in drought intensity, making the development of new drought-tolerant rice cultivars critical to sustain rice production in this ecosystem.
