摘　　要：Genetic diversity and relationships of wild goat grass （Aegilops tauschii Cosson） from Iran and Xinjiang, west China, as well as its weedy type from the Yellow River region of Shaanxi and Henan provinces in China were analyzed by simple sequence repeat （SSR） fingerprints. A high level of genetic diversity in Aegilops tauschii accessions from Iran was observed, and the richness of genetic diversity was followed by accessions from Shaanxi, Henan, and Xinjiang. The weedy type of Aegilops tauschii showed a close genetic relationship with the wild type from different regions in Iran. The results indicated that the weedy Aegilops tauschii found in the Yellow River region was most likely introduced from Iran--the diversity center of Aegilops tauschii. The weedy Aegilops tauschii populations found in the Yellow River region may be brought into the central part of China as a weed species together with common wheat （Triticum aestivum L.） from the West during various periods of time in history. This finding has provided strong evidence for the introduction of common wheat from the West into China via the Silk Road, and also demonstrated the important role of the Silk Road in the exchange of agriculture and other relevant technologies between China and the West.从伊朗和 Xinjiang，西方中国，以及它从在中国的 Shaanxi 和河南省省的黄河区域的蔓延的类型的野生的山羊草(Aegilops tauschii Cosson ) 的基因差异和关系被简单顺序重复(SSR ) 分析指纹。在从伊朗的 Aegilops tauschii 就职的基因差异的高水平被观察，并且基因差异的丰富被就职从 Shaanxi，河南省，和 Xinjiang 跟随。Aegilops tauschii 的蔓延的类型在伊朗从不同区域与野类型显示出一种近基因的关系。结果显示在黄河区域发现的蔓延的 Aegilops tauschii 很可能从伊朗被介绍—Aegilops tauschii 的差异中心。在黄河区域发现的蔓延的 Aegilops tauschii 人口可以在时间的各种各样的时期期间从西方和普通小麦(Triticum aestivum L.) 作为杂草种被带进中国的中央部分历史上。这发现经由丝绸道路从西方为普通小麦的介绍提供了充分证据进中国，并且也在在中国和西方之间的农业和另外的相关技术的交换表明了丝绸道路的重要角色。
