| 摘 要： | 用中国春单体系列和对Ｇａｒｕｄａ＂ｓ＂无毒性的两个小麦秆锈菌系２１Ｃ３ＣＴＲ和３４Ｃ２ＭＫＲ对Ｇａｒｕｄａ＂ｓ＂进行了抗秆锈病基因的单体分析，并将Ｇａｒｕｄａ＂ｓ＂所含的抗秆锈基因与国际上已命名的Ｓｒ基因进行了异同比较。结果表明：Ｇａｒｕｄａ＂ｓ＂在２Ｂ染色体上含有Ｓｒ９ｂ，它抗秆锈菌系２１Ｃ３ＣＴＲ，侵集型为０－２－；在６Ｂ染色体上携带抗病基因Ｓｒ１１，它只抗３４Ｃ２ＭＫＲ，侵染型为０－；１；在５Ｄ染色体上含有兼抗２１Ｃ３ＣＴＲ和３４Ｃ２ＭＫＲ的抗病基因Ｓｒ３０，它控制０－２的侵染型。对无毒性的菌系，Ｓｒ１１对Ｓｒ３０的抗病效应是上位的。此外，Ｇａｒｕｄａ＂ｓ＂对秆锈菌系２１Ｃ３ＣＴＲ的抗性可能是Ｓｒ９ｂ和Ｓｒ３０累加作用的结果，或许还有其它修饰基因的影响。

| Abstract: | Monosondc analySis of resistant genes in Garuda "s" to stem rust pathotypes 21C3CTR and 34C2MKR werecarried out. The results showed that Garuda "s" carried three independent and dominant genes, one gene Sr9b onchromosome 2B for resistance to pathotype 21C3CTR, one gene Sr11 on chromosome 6B for resistance to34C2MKR, and the other gene Sr30 on chromosome 5D for resistance to 21C3CTR and 34C2MKR. Gene Sr11 isepistatic to gene Sr30 according to the test with pathotype 34C2MKR. The resistance to 21C3CTR in Garuda"s" isbecause of the additive effect of Sr9b and Sr30, and other modifying genes may also exist. |
