Abstract: An experiment was conducted to compare fifteen lowland rice (Oryza sativa L.) genotypes for drought tolerance based on some physiological parameters in germination stage. Five levels of water stress (0, -3.0, -5.0, -7.5 and B10 bars) treatments were given with polyethylene glycol (PEG 6000). The water solutions were replaced with fresh solutions regularly. Seed germination percentage and seedling growth decreased with increasing water stress in all the genotypes. Among the genotypes, Tarom, Khazar, Fajr and Nemat recorded better germination and seedling growth in terms of radicle and plumule length under stress conditions than other genotypes.
