Diversity in characteristics controlling tolerance to heat induced floret sterility in rice and their effects to the tolerance were examined. The observed range of basal dehiscence length was 590μm. The effect of 590μm of difference in dehiscence on heat tolerance was estimated at 4^℃. The observed range of transpiration conductance was 340 mmol・m^<-1>・s^<-1>. The effect of difference of 340 mmol・m^<-1>・s^<-1> on panicle temperature was estimated to be 3.8℃ in certain case by the simulation model of panicle temperature. Moreover, diversity of 3. 5 hrs in Flowering time was observed.

研究了水稻耐热小花不育性状的多样性及其对耐热性的影响。观察到的基裂长度范围为590μm。在4^℃下，估计了590μm的开裂差异对耐热性的影响。蒸腾导度的观测范围为340 mmol·m^<-1>·s^<-1>。利用穗温模拟模型估算出340 mmol·m^<-1>·s^<-1>对穗温的影响在一定情况下为3.8℃。此外，多样性3。开花时间为5小时。
