Drought is one of the most important stress that reduce the growth yield and development of crops. Soybean is the most important source of food, protein and oil and hence more research is essential to increase its yield under different conditions including stress. Developing drought tolerance and other abiotic stress resistance soybean cultivars is an important goal throughout the world. Germination is one of the main growth stage for seedling establishment and is dependent on moisture availability in soil. The experiment was carried out to evaluate the germination and other characteristics of six soybean genotypes (JS-335, JS-93-05, KDS-344, PUSA-20, MAUS-162andMACS-57) under four levels of osmotic stress (control, 5%, 10%, 15%, 20%). Polyethylene glycol (PEG) 6000 was used as osmoticum. This investigation was performed as factorial experiment under Completely Randomized Design (CRD). Germination and early growth was affected by drought stress. The observations were made on germination percentage, plant shoot length, shoot fresh weight, shoot dry weight, root length etc. the result indicated that the two soybean genotypes MAUS-162 and PUSA 20 exhibited tolerance against drought stress compared to other varieties. The variation among genotypes for germination and other biological parameter was found to be a reliable indicator to screen the drought tolerant genotypes at germination seedling stage in soybean.
