Three popular traditional rice landraces, namely Kalajeera, Machakanta and Haladichudi, from Koraput, India were used to analyse the leaf traits and antioxidant defence for drought tolerance. When rice plants were exposed to different levels of drought stress by varying concentrations of polyethylene glycol （PEG） 6000, seed germination and growth parameters were significantly declined in all the rice landraces compared to the control. Drought stress also altered the leaf phenotypic traits based on chlorophyll fluorescence parameters and chlorophyll index, with more significant differences in susceptible variety IR64 than in traditional landraces. Furthermore, activities of antioxidative enzymes and proline and protein contents overtly increased under drought stress. The traditional rice landraces showed higher relative ratios for different parameters compared to the susceptible variety IR64. Taken together, the traditional landraces had superior leaf physiological efficiency compared to the susceptible and tolerant check varieties under drought stress.

Drought stress is a serious limiting factor to rice production,which results in huge economic *** is becoming a more serious issue with respect to the global climate *** in view of the current and forecasted global food demand,it has become essential to enhance the crop productivity on the drought-prone rainfed lands with *** order to achieve the production target from rainfed areas,there is a requirement of rice varieties with drought tolerance,and genetic improvement for drought tolerant should be a high priority theme of research in the *** for drought tolerant rice varieties is a thought-provoking task because of the complex nature and multigenic control of drought tolerant traits would be a major bottleneck for the current research.A great progress has been made during last two decades in our understanding of the mechanisms involved in adaptation and tolerance to drought stress in *** this review,we highlighted the recent progresses in physiological,biochemical and molecular adaptation of rice to drought tolerance.A brief discussion on the molecular genetics and breeding approaches for drought tolerance in rice will be focused for the future crop improvement program for development of drought tolerant rice varieties.
