Abstract：Rice is one of the main food crops.Whether rice can achieve high yield has a certain impact on people's daily diet.With the continuous increase of population,the demand for food output is also increasing.The low temperature condition of rice may lead to the decrease or even the loss of crop.Therefore,planting cold-tolerant rice varieties is an effective way to solve this problem.The research progress of cold tolerance was reviewed from two aspects:identification of cold tolerance at bud stage,seedling stage and pregnancy stage,and QTL(quantitative trait locus)mapping of cold tolerance genes in rice,which can provide a basis for the mechanism of cold tolerance of rice in cold areas and the screening and identification of cold-tolerant varieties in the future.
