摘要:选用16个小麦叶锈菌菌系对14个小麦品种(系)进行抗叶锈性鉴定和苗期抗叶锈基因推导,初步分析这些品
种(系)的抗性和携带的抗病基因;进一步利用21个与Lr基因紧密连锁或共分离的分子标记,对这14个品种(系)中可
能含的抗叶锈基因进行鉴定。结果表明,s98351-2-2-2-1可能含Lr3a、Lr28和Lr50;9629-03A-4-1-1可能含Lr37;
97167-1-2-1-1-2-1、919-20-2c2、9589、免中438、9916-8-6和9916-8-18含Lr26;96104-1-5-1c2可能含Lr28;00-55-3-1-1
含Lr1;1R13可能含Lr24、Lr37和Lr38;1R17可能含Lr24和Lr38;1R35含Lr10和Lr34,还可能含Lr3a和Lr50;
9524-1-2-2-1含未知抗叶锈基因或本试验使用的已知抗病基因以外的抗叶锈基因。所有品种(系)均不含Lr9、Lr19、
Lr20、Lr21、Lr29、Lr35、Lr42和Lr47基因。测试的14个品种(系)中有比较丰富的抗叶锈病基因,可为育种提供丰
富的抗源。
