This paper deals with the morphological and anatomical structure of soybean varieties which have different drought resistance in the field condition.The main results were as follows:As compared with drought sensitive varieties,the drought resistance varieties of soybean were characterized as that,their seeds germinated fast and the seedlings sent out more seconday-roots; their roots grew more quickly and the root system well developed which main root penetrated deeply in soil.As much more root quantity distributed in deep soil,the root systems were belonged to 'deep root type',The root system had.higher dry matter content and larger active absorbing surfance.The conducting tissues of foot system ware well developed because more vessels in it.
