This study was performed to know the influence of high temperature on the flowering and setting of pods in kidney bean. The varieties tested were Kurozuru and Kisasage. 1. The temperature had a strong influence on the setting of pods and ripenning of seeds in kidney bean. The correlation coefficient of set percentage and temperature at 10 a. m. were as follows:- runner type γ=-0.699 P<0.001 dwarf type γ=-0, 739 P<0.001 2. There were three stages of flower abscission in runner type, i. e., early stage, middle stage, and late stage. 3. It was expected that the flower abscission of early stage was due to shortage of nutrient by spending to plant development. 4. Flower abscission of middle stage would be owing to competition of nutrient among flowers. 5. Flower abscission of the late stage was consi-dered to be due to the decline of plant and the influence of high temperature.
