The effects of water deficit on various morpho-physiological traits associated with drought tolerance were also studied. Analysis of variance revealed highly significant variation among the genotypes for all the characters under study in both conditions (stress and normal). A set of 33 rice genotypes including four checks viz., Sahbhagidhan, Vandana, Rasi and APO were evaluated under vegetative and reproductive stage, drought stress and normal conditions during kharif 2011-12 with objectives to estimate genetic variability, character association and path analysis for various traits to identify stress tolerant genotypes. In order to design efficient varieties with virtues of drought tolerance and high yielding ability is necessary. Rice (Oryza sativa L.) is the most important food crop of the world drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Climate change needs us to look at various alternatives for more drought tolerant and tougher strains.
