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。
Garuda “s” was subjected to a monomeric analysis of the stem rust resistance gene using Chinese Spring Monomer Lines and two wheat stem rust strains, 21C3CTR and 34C2MKR, non-toxic to Garuda “s” The similarities and differences between the anti-stalk rust genes and the internationally named Sr genes were compared. The results showed that: Garuda “s” contained Sr9b on chromosome 2B, which was resistant to Stems rust strain 21C3CTR and its invasion type was 0-2-. On chromosome 6B, it carried resistance gene Sr11, which was only resistant to 34C2MKR. The infection type was 0-; 1; 5D chromosome containing anti-21C3CTR and 34C2MKR resistant gene Sr30, which controls 0-2 infection. For non-toxic bacterial strains, the effect of Sr11 on Sr30 is superior. In addition, the resistance of Garuda “s” to the stalk rust strain 21C3CTR may be the result of the additive effect of Sr9b and Sr30, perhaps with other modifying genes.
