| 摘 要： | １９９２～１９９４年对２１个小麦抗病亲本和４个感条锈、白粉病程度不同的农艺亲本所配置的８３个杂交组合Ｆ１的病害反应型（或侵染型）进行了研究，结果表明，杂种Ｆ１的抗病性主要取决于抗病亲本，但农艺亲本在改善抗病基因所处的遗传背景以增强其抗病能力方面产生了很大影响。

| Abstract: | The study on the infection types of F1 hybrids of 83 crosses from 21 wheat parents with disease -resistance and 4 wheat parents with some excellent agronomic traits and different degrees of susceptibility to strip rust and powder mildew,in 1992～1994 showed that the disease -resistances of F1 hybrids were mainly depended upon the disease -resistant parents.But the parents with excellent agronomic traits played an im- portant role in improving the hereditary background of the disease resistant gene and enehancing their disease -resistani ability |
