以美国11个苜蓿秋眠性标准品种为对照，依据 Teuber 等方法连续两年（2013年和2014年）在内蒙古西部干旱地区评定国内和国外引进的共45个苜蓿品种的秋眠级，建立了11个标准品种秋眠级与秋季再生株高的回归关系。结果表明，苜蓿秋季刈割后第21天的再生自然株高与原秋眠级存在真实的线性回归关系，R 2分别为0．9643和0．9867。相关性分析表明，11个标准对照品种的实际秋眠级与原秋眠级之间相关系数为0．994，存在极显著正相关；13个已知原秋眠级的引进品种的实际秋眠级与原秋眠级之间的相关系数为0．969，存在显著正相关。聚类分析表明，21个国内苜蓿品种中90％的为秋眠和极秋眠类型，其中渝苜1号、甘农5号和凉苜1号实际秋眠级评定结果分别为6．8，7．4和8．5，属于非秋眠类型，国外引进品种秋眠类型多样性高，各种类型均有分布。

Following the methods of Teuber and using 11 different American fall dormancy standard alfalfa cultivars as contrasts,we assessed the fall dormancy class of 45 alfalfa cultivars from the drought area of western Inner Mongolia in 2013 and 2014.We conducted a regression analysis of the relationship between fall dormancy class and natural plant height after final clipping and compared results with the 11 American cultivars.Results showed that natural plant height at 21 days after autumn clipping and fall dormancy class had a linear relationship with R 2 of 0.9643 and 0.9867 respectively.Analysis showed that the correlation coefficient between actual fall dormancy class and the 11 comparator varieties is 0.994.The correlation coefficient for 13 known fall dormancy introduced varieties is 0.969.Cluster analysis showed that 90% of 21 domestic alfalfa cultivars are either dormant or highly dormant types.The actual fall dormancy classes of Yumu No.1, Gannong No.5 and Liangmu No.1 were 6.8,7.4 and 8.5,indicating that they belong to the non-dormant type.
