１９９４年在国内８省区３５个县的８３个小麦品种上采集到小麦秆锈病标样２０１份，繁殖存活了１３６份，在分离到的３３２个菌株中鉴定出２１Ｃ３、３４、３４Ｃ１和３４Ｃ２四个生理小种；２１Ｃ３ＣＫＲ、２１Ｃ３ＣＫＨ、２１Ｃ３ＣＴＲ、２１Ｃ３ＣＴＨ、２１Ｃ３ＣＰＲ、２１Ｃ３ＣＰＨ、２１Ｃ３ＣＦＲ，３４ＭＦＧ、３４ＭＫＧ，３４Ｃ１ＭＫＲ、３４Ｃ１ＭＫＨ，３４Ｃ２ＭＫＲ、３４Ｃ２ＭＫＫ、３４Ｃ２ＭＦＫ、３４Ｃ２ＭＫＨ等１５个致病类型。生理小种２１Ｃ３出现频率为７７．０％，３４Ｃ２为１６．１％位居第二，３４为６．０％，３４Ｃ１为０．９％；各致病类型的出现频率依次为２１Ｃ３ＣＫＲ３１．６％、２１Ｃ３ＣＴＲ３１．０％、２１Ｃ３ＣＫＨ和２１Ｃ３ＣＰＲ均为４．８％、２１Ｃ３ＣＴＨ３．０％、２１Ｃ３ＣＦＲ１．２％、２１Ｃ３ＣＰＨ０．６％，３４ＭＫＧ３．９％、３４ＭＦＧ２．１％、３４Ｃ１ＭＫＲ０．６％、３４Ｃ１ＭＫＨ０．３％、３４Ｃ２ＭＫＲ６．７％、ＭＫＫ５．８％、３４Ｃ２ＭＫＨ３．０％、３４Ｃ２ＭＦＫ０．６％，２１Ｃ３ＣＫＲ和ＣＴＲ出现频率明显高于其它致病类型。２１Ｃ３ＣＴＲ自１９９３年发现以来，出现频率上升很快，在云南、四川、湖北?
In 1994, 201 wheat stripe rust samples were collected from 83 wheat cultivars in 35 counties of 8 provinces and autonomous regions in China, 136 of which were propagated for breeding. Among the 332 isolates identified, 21C3, 34, 34C1 and 34C2 tetra A total of 15 pathotypes including 21C3CKR, 21C3CKH, 21C3CTR, 21C3CTH, 21C3CPR, 21C3CPH, 21C3CFR, 34MFG, 34MKG, 34C1MKR, 34C1MKH, 34C2MKR, 34C2MKK, 34C2MFK and 34C2MKH. Physiological race 21C3 was found in 77.0%, 34C2 16.1%, 34% 6.0% and 34C1 0.9%. The occurrence frequency of each pathogenicity was 21C3CKR31.6% , 21C3CTR31.0%, 21C3CKH and 21C3CPR were 4.8%, 21C3CTH3.0%, 21C3CFR1.2%, 21C3CPH0.6%, 34MKG3.9%, 34MFG2.1%, 34C1MKR0.6%, 34C1MKH0.3% , 34C2MKR6.7%, MKK5.8%, 34C2MKH3.0%, 34C2MFK0.6%, 21C3CKR and CTR were significantly higher than other pathogenic types. 21C3CTR since its discovery in 1993, the frequency of occurrence of the rapid rise in Yunnan, Sichuan, Hubei?
