This experiment was performed concerning the effects of high temperature in summer on the flowering and set of pods of common bean varieties in 1948.
For this purpose were used ten varieties. From the results of this experiment, set percentage of pods is generally-decreased by high temperature. But this effect is rather widely differen-tiated among these varieties, and these varieties are classified into three types, that is to say, high temperature type, medium temperature type, and low temperature type,
The varieties which have many flowers and high' percentage of set are classified into high temperature type.
The varieties of low temperature type are not adapted in Tokyo prefecture.
The varieties of medium type are possible to obtain high percentage of set by earlier sowing.
