Taking the cold tolerance identification experiment of mid-rice production test varieties in the upper reaches of the Yangtze River and Wuling Mountain area in 2016 as an example, the method of identification and evaluation of cold tolerance in heading-flowering stage of rice with the combination of high and low mountain identification nursery was introduced in this paper. At the same time, the practicability and stability of the identification method were discussed by analyzing the test results of multi-channel tested varieties in the last 5 years, and preliminary suggestions for improvement were put forward.
Key words: rice; heading-flowering stage; cold tolerance; identification; evaluation
