中文摘要：
以19个名称相同且地理来源均在3个以上的104份甘肃省地方小麦品种为供试材料,对小麦的13个形态性状进行了鉴定和聚类分析。结果表明：名称不同的品种之间变异比较丰富,同一名称不同地理来源之间变异程度不一致;聚类分析将供试材料聚为5个大类和10个亚类,进一步显示出地方品种的遗传多样性,其中金包银、小白麦、小红麦的不同来源材料分别分布于4个大类（或3个大类＋1个亚类）中,即代表4种类型;而白光头、青芒麦等有3种类型,白春麦、齐头麦等仅2种类型。
英文摘要：
By using 104 wheat landraces with 19 same names but from over 3 geographical locations as materials, 13 morphological characters were identified and cluster analysis was conducted. The results showed that there were much abundant variations among the landraces with different names and there were different levels of variation among the landraces with the same name. The 104 landraces were divided into five groups and ten subgroups according to the results of cluster analysis. The landraces of Jinbaoyin, Xiaobaimai, Xiaohongmai from different origins were designed to four groups （or three groups and one subgroup ）, representing four types. However, Baiguangtou and Qingwangmai had three types, and Baichunmai and Qitoumai had only two types.
