摘 要 ：中国春单体分析表明，四倍体小麦－粗山羊草双二倍体Ａｍ６的抗白粉病基因位于１Ａ染色体上，与２４个已知抗白粉病基因比较说明，Ａｍ６可能为一新的抗白粉病基因。限制性片段长度多态性分析表明，在分布小麦７个部分同源群的３６个探针中未找到与此抗病基因连锁的分子标记。

Abstract:Results of monosomic analyses revealed that the powdery mildew resistance gene in Am6, an amphidiploid between Triticum durum Desf. and Aegilops tauschii (Coss. ) Schna. , was located on chromosome 1A. RFLP markers were analyzed by using bulked segregant
