摘　　要：中国六倍体普通小麦地方品种有一个比较独特的特征———存在丰富的高亲和性材料。因此，研究中国四倍体小麦的亲和性问题具有特殊的意义。“简阳矮兰麦”是来源于四川省的一个四倍体小麦地方品种，它与黑麦有高的可杂交性，其杂交结实率达６０％。遗传分析表明，“简阳矮兰麦”与黑麦的高可杂交性是受２～３对隐性基因所控制，但３对基因的可能性更大。而且，这些隐性基因的作用在合成六倍体小麦后仍能比较完全的表达。通过与六倍体普通小麦相比较，结果表明四倍体小麦的可杂交性系统与六倍体小麦的可杂交性系统的作用方式是类似的。It is a special characteristic that many Chinese common wheat landraces showed a high crossability with rye Thus, it is important that elucidate the genetic control of the crossability of Chinese tetraploid wheat with rye Triticum turgidum cv Jianyangailanmai native to Sichuan, China has high crossability with rye, up to 60% In this study, it is indicated that the crossability of Jianyangailanmai with rye is controlled by two or more probably three recessive genes, which was almost totally expressed in the hexaploid wheat level The operation of these recessive genes influencing crossability with rye was similar to that of hexaploid common wheat
