水稻新品种耐低温鉴定试验研究初报及建议

笔者以2014年湖南省晚稻生产试验品种,及长江中下游稻区早熟晚籼生产试验品种为材料,对耐低温鉴定的方法、低温时段的选择、等级的评判标准以及试验中存在的问题进行了探讨,并对如何更好的开展耐低温鉴定试验提出了一些建议。

Preliminary Report and Recommendations of Rice Qualification Test to Low Temperature Resistance

The late rice varieties of Hunan Province and the early maturity varieties of late indica rice of the middle and lower reaches of the Yangtze river, were chosen as trial materials in this paper in 2014. The method of indentification, low temperature period selec-tion, establishing of standards and the existing problems were discussed and put forward some suggestion to the low temperature resis-tant appraisal.
