A set of 45 soybean genotypes were evaluated at reproductive stage under water restricted and well watered conditions to identify drought tolerant genotypes. Five indices including plant height stress index (PHSI), root length stress index (RLSI), dry matter stress index (DMSI), relative water content stress index (RWCSI) and yield stress index (YSI) were applied for the selection of drought tolerant genotypes. Genotype JS 20-71, followed by JS 20- 95 and JS 20-117 were found to be highly drought tolerant. Whereas, genotypes JS 95-60, CG soya, JS 20-121 and JS 335 were identified as most sensitive to drought.
