Rice is one of the most important staple foods for the human population. More than 2000 million people obtain 60–70% of their calories from rice and its products in Asia alone. It is the grain with the second highest worldwide production. China, India, Indonesia and Bangladesh are the largest producers of rice. Climate change and global warming are two main reasons that concern sustainable food production. Drought is a major environmental stress factor that affects the growth and development of rice plants. Drought or soil water deficit can be chronic during the period of plant growth. Thus, understanding drought stress and water use in relation to plant growth are utmost important for sustainable agriculture. Keeping the severe effects of drought in mind, the present investigation was carried out in the Norman E. Borlaug Crop Research Centre and Department of Plant Physiology, G.B. Pant University of Agriculture and Technology Pantnagar, to evaluate morphological characterization of different drought tolerant rice genotype under field condition. In this experiment, 16 genotypes of rice were taken with three replications of each genotype. Two treatments were given at the time of flowering i.e., irrigated (control) and non irrigated (drought). The different observations were taken like Plant height, Number of tiller, grain yield, total dry matter, leaf area index and 1000 grain weight. Under the investigation, it was observed that plant height, total dry matter, leaf area index rest other parameters all are decreased under drought (non irrigated) condition compared to control (irrigated) condition. Therefore, morphological parameters may be used for screening of drought tolerant varieties of rice.
