水稻品种抽穗扬花期耐冷性鉴定与评价方法初探

Preliminary Research on Identification and Evaluation of Cold Tolerance of Rice in Heading-flowering Stage

笔者以2016年承担的武陵山区、长江上游稻区中稻生产试验品种耐冷性鉴定试验为例,详细阐述了采用高山鉴定圃和低山鉴定圃相结合的水稻抽穗扬花期耐冷性鉴定与评价方法,同时通过分析近5年多渠道参试品种的试验结果,探讨了该鉴定方法的实用性和稳定性,并初步提出了改进建议。

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.
