In vitro screening method is an ideal method for evaluation of large set of germplasm accurately and cost effectively. The experiment was carried out with twenty chickpea genotypes in completely randomized design. Polyethylene glycol 6000 (0, -0.2, -0.4MPa) and mannitol (2% and 4%) were used for creating different moisture stress levels. Germination percentage, seedling length, seedling fresh weight and dry weight, vigour index were considerably lowered while membrane permeability index raised with the rise of osmotic stress levels. More considerable reduction was obtained under polyethylene glycol than under mannitol, due to greater water stress caused by former substrate. The highest values of germination parameters were obtained with no osmotic potential and least values were found with -0.4 MPa PEG concentration. Genotypes GL22044 and GNG1861 were found to be sensitive and RSG 963 and PDG3 emerged as tolerant genotypes. .
