为鉴定张家口地区燕麦主栽品种与野生种之间的亲缘关系，对1个四倍体野燕麦及9个裸燕麦品种进行AFLP分析。分析结果显示，供试的燕麦个体间遗传一致度分布在0．5268～0．8696，各裸燕麦品种与野燕麦的遗传一致度分布在0．5268～0．8018，其中6号栽培品种与野燕麦间的遗传一致度最高，7号次之，2号最低。根据遗传一致度进行聚类分析同样显示1，3，4，5，7号样本聚为一类，在遗传距离0．314处，又可分为2组，即1号和6号样本聚为一组，其他样本聚为一组。这些结果表明6号品种与野燕麦亲缘关系最近，较大程度上继承了野燕麦的遗传信息，推测其父本或母本可能是4倍体野燕麦或与野燕麦的杂交品系。

To identify the genetic relationship between the main oat cultivars in Zhangjiakou region and wild species ,9 oats cultivar and one tetraploid wild oat were analysed by ALFP .The results showed that the Nei′s genetic identity among the oats for the test distributed in 0.526 8~0.869 6,and values of among each oat cultivars and wild ranged from 0.526 8 to 0.801 8.The 6th cultivar had the highest genetic identity value with wild oat ,No.7 fol-lowed,and the No.2 was lowest.Cluster analysis showed that No.1,3,4,5,and 7 samples clustered a group,in the genetic distance 0.314,based on genetic identity.They can be divided into two groups,the 1st and the 6th samples grouped into a group , the other samples grouped together .These results suggested that the No .6 variety was most closed with tetraploid wild oats ,inherited the genetic information of wild.
