Abstract: In order to analysis the responses of different varieties of early rice under waterlogging stress, in this paper, the different varieties of rice tillering, heading and flowering flooded ability submergence strength resistance to impact on some agronomic traits, evaluations of submergence tolerance at tillering stage, heading stage and effects of different submergence stress on some agronomic characters in rice were studied. Results showed that, in tillering stage, indica rice varieties in different flooded waterlogging strength between the processing plant height change different results. Different waterflooding treatment plot appears caulis ear and tillers spike development process not consistent, growth period extend days and flooded between days showed extremely significant positive correlation. Because the plant of ‘Xiangzaoxian24’ was relatively low, the Tryporyza incertulas hazard was serious. Tryporyza incertulas Occurrence area and flooded strength showed extremely significant positive correlation. Flood water treatment caused the rice yield reduced; the experimental result indicated that, the same variety production by submerged water with the time extension and increase.
