[Current status and research advances of late spring coldness in wheat]

Low temperature disasters in wheat occur frequently in recent years, due to global warming. Late spring coldness in wheat during jointing-booting stage is one of the important factors limiting the yield and quality of wheat. Here, we summarized the occurrence characteristics (identification, classification, and space-time characteristics) of late spring coldness in wheat, and the effects of late spring coldness on physiological characteristics (leaf, stem, spike, and root), yield and quality of wheat. Furthermore, we reviewed the research progresses on the breeding of late spring coldness tolerant wheat, molecular biology mechanism, the monitoring, early warning and risk assessment of late spring coldness. Finally, future research work on genetic basis of wheat resistance to late spring coldness, evaluation system for wheat damaged by late spring coldness, prevention and control technology system were prospected to provide a theoretical basis for genetic improvement and new cultivation regulation measures of the resistance of wheat varieties to late spring coldness.
