Crop growth, development and productivity are affected adversely by various abiotic stress in which drought is one major upcoming problem due to increasing global temperature. The study was conducted to understand the adaptation behaviour of the crop plant against drought-prone environment. This article describes morphological changes that occurred after treating seeds of 20 different Indian wheat cultivars with PEG-6000 in three different concentrations i.e. 10%, 20% and 30% for inducing drought conditions. The observations were taken after sowing seeds in Randomized Block Designed field which resulted in reduced germination percentage, root length, shoot length, plant height, flag leaf area, length of spike, number of tillers per plant, number of spikelet per spike, number of grains per spike and thousand grain weights. The results showed that induced drought stress significantly reduced their value with increasing stress level. The germplasm HD2733 and K9107 show very less effect of induced drought stress and maintained their yield potential even after the third level of stress condition. This study may become helpful in searching drought tolerant genotypes for further breeding and biotechnological manipulations for generating novel and improved wheat variety.
