High temperature-induced rice sterility at anthesis is characterized by its organ-specific, high severity, and low predictability of occurrence. This paper summarized the research advances in rice sterility at anthesis under high temperature, including occurrence period, injury temperature regime, differences in responses among varieties, damage mechanisms, evaluation methods, genetics of tolerance traits, and molecular biology of anther dehiscence and pollen abortion, etc. Based on the relevant researches in Japan as well as the studies in Jianghan Plain, China on the climate conditions under which high temperature-induced damage on middle-season rice hybrids occurred, some key points and main options for the further research were suggested.
