抗稻瘟病基因Piz-t和Pi9连锁标记开发及在云南粳稻中的应用
云粳优5号、云资粳41号和楚粳28号是农艺性状优良但对稻瘟病抗性弱的粳稻品种,采用回交的方法将2个广谱抗稻瘟病的基因Piz-t和Pi9导入这些品种以改良这3个品种的抗稻瘟病特性。为提高后代抗病材料选择的准确性和效率,本研究开发获得5个与Piz-t和Pi9基因紧密连锁并且在供体亲本和受体亲本间具有多态性的分子标记。利用分子标记跟踪检测来源于供体亲本与受体亲本回交获得的BC1F1单株中Piz-t和Pi9基因,并进一步利用对受体亲本云粳优5号、云资粳41号和楚粳28号致病,但对持有Piz-t和Pi9基因的供体亲本不致病的稻瘟病菌09BSH-10-5A进行接种分析。结果显示,携带有供体亲本和受体亲本D...

Two genes Piz-t and Pi9 with broad-spectrum resistance to rice blast were introgressed into them to improve their resistance to rice blast by backcross strategy. In order to improve the accuracy and efficiency of selection of resistance individuals to rice blast,5 molecular markers polymorphic among parents,and closly linked with Piz-t and Pi9 genes,were developed. These markers were used for genotyping the BC1F1 plants derived from the crosses between susceptible japonica cultivars and r |
