Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.
