Identification and mapping of QTLS for drought resistance in rice

Rice (Oryza sativa 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.
