摘要:
为了明确周麦11、西农1163-4抗叶锈病基因与周8425B中LrZH84的关系,用叶锈菌小种THTT接种周麦11/中国春的145个F2单株,而另一叶锈菌生理小种FHTT分别接种周麦11/中国春的285个F2单株、西农1163-4/Thatcher的232个F2单株;2个与LrZH84紧密连锁的标记gwm582、ω-secalin/Glu-B3用于检测3个群体中是否携带抗叶锈病基因LrZH84。结果显示:周麦11对叶锈菌生理小种THTT的抗性由2个显性抗病基因控制,经标记检测发现,周麦11中1个抗病基因是LrZH84,另1个抗叶锈病基因为未知基因;周麦11对叶锈菌生理小种FHTT的抗性由单基因控制,标记检测发现该基因不同于LrZH84,为未知抗叶锈病基因;西农1163-4对叶锈菌生理小种FHTT的抗性由单基因控制,分子标记检测结果表明,该基因可能为LrXi,由于LrZH84对FHTT表现感病,表明LrXi不同于LrZH84。通过研究证实,周麦11中含有LrZH84和1个未知的抗叶锈病基因,西农1163-4中的抗叶锈病基因LrXiLrZH84不同;同时,周麦11、西农1163-4中可能还含有其他抗病基因,有待进一步研究。研究将为抗病基因聚合、基因布局、培育抗病新品种奠定理论基础。
