Abstract: High temperature stress occurs frequently in rice due to global warming. High-temperature hazard during the booting-flowering and grain-filling stages is one of the major factors limiting rice yield and quality. Here, we summarized the occurrence characteristics (identification, classification, region, and time) of high-temperature hazards, and the effects of high temperature on rice growth and development, including physiology, grain yield, and grain quality. Furthermore, we reviewed molecular biology aspects including quantitative trait locus mapping, transcriptome analysis, proteome analysis, and the monitoring, early warning, risk assessment of high-temperature hazards in rice. The defensive measures against high temperature in rice including selecting heat-resistant varieties, improving field management practices and spraying exogenous substances were intensively described. Finally, future research work on high-temperature hazards in rice was prospected to provide the scientific support for rice high-temperature defense, agricultural disaster reduction, and agricultural efficiency improvement.

Key words: rice, high temperature, grain yield, grain quality, risk assessment
