Abstract:

明确来源于野生二粒小麦的抗白粉病基因PmAS846所在的染色体臂。采用端体和SSR标记对普通小麦种质N9134携带的PmAS846基因进行了遗传分析。中国春(ChineseSpring,CS)、CS5BL双端体系与N9134杂交F1高抗白粉病,CS/N9134的F2和CS5BL双端体系/N9134//CSBC1F1抗病植株和感病植株比例分别符合期望比例3∶1和1∶1。CS5BL双端体系/N9134//CSBC1F164个植株的根尖染色体核型和白粉病抗性鉴定发现,12个植株在5B染色体着丝点和抗性基因间发生了交换。PmAS846的SSR标记Xgwm67在CS第五部分同源群的缺体-四体系和双端体系的扩增,该标记在CSN5BT5D系中缺失,而在CSDt5BL系中存在。结果表明:PmAS846位于小麦5B染色体长臂上,该基因距5B染色体着丝点18.75个交换单位。
