Abstract Low temperature stress seriously affects the yield and quality of maize and restrict the development of maize industry. This paper analyzed the effect and harm of low temperature on maize production， summarized the inheritance of low temperature tolerance in maize， QTL mapping of low temperature tolerance related genes， and the research progress of multiomics technology of low temperature tolerance in maize， which aimed to provide reference for screening and breeding of low temperature tolerance germplasm resources in maize.
