Abstract：Ten soybean cultivars popularized in Huanghuaihai Valley region were used in the experi-ment,and their waterlogging tolerances at seedling,flowering and the whole growth stages were evaluated. The results showed that there were all certain influences on soybean growth when waterflooding at seedling, flowering and the whole growth stages.The leaves got yellow,the plant height decreased,the growth delayed, the main root rotted,which was replaced by adventitious roots for performing function,and the yield and qual-ity declined.Among which,waterflooding at flowering and the whole growth stages had greater effects on yield.In all the experimental cultivars,Qihuang 42 had better tolerance to waterflooding at three stages,Qi-huang 34 and Zhonghuang 37 possessed stronger tolerance to waterflooding at flowering and the whole growth stages,while Jidou 17 and Zheng 92116 owned the weakest waterflooding tolerance at three stages.
