1. To explain the mechanism of the resistance of rice varieties against the salt, 120 varieties were tested at the field where the salt injuries happened usually. 2. At this field, as the concentration of chlorine became higher in the later term of rice plant growth, the heading term influenced on the degree of these injuries (20-24th Aug. and 20th Sep.) very much. 3. It was considered, to become higher the concentration of chlorine from 20 th to 24 th Aug. made the sterilizing percentage of the varieties which met with it at the reduction division period higher, and the weight of 1000 grains of the late mature varieties and the harvest weight were lightened as the concentration became higher from both Sep. 4. From this result, it was recognized that the varieties which avoid the injuries must be considered, too.
