520 _aIdentification of stripe rust resistance genes is extremely important for developing new resistant cultivars to control the disease. A total of 98 Chinese wheat cultivars and advanced lines were inoculated with 26 isolates ofPuccinia striiformisf. sp.tritici(PST) for postulation of stripe rust resistance genes at seedling stage. The results indicated that 42 cultivars and lines possess the resistance geneYr9, either independently or in combination with other resistance genes. Nineteen accessions carryYr24orYr26. Seven entries showed resistant to the 26 isolates tested, whereas, six cultivars and lines were susceptible to all of them. It was indicated in the test thatYr10, Yr15, Yr24, andYr26were effective resistance genes against Chinese PST isolates, whereasYr1andYr6were susceptible to them. SSR analysis indicates thatYrCH42in Chinese wheat cultivar Chuanmai 42 is closely linked toXgwm498andXwms273, with genetic distances of 1.6 cM and 2.7 cM, respectively.YrCH42,Yr24andYr26are probably common genes according to their reaction patterns to the 26 isolates tested, as well as their chromosomal location and origins. In addition, a new stripe rust resistance gene on chromosome 7BL was detected in the Chinese wheat line Zhou 8425B, which is closely linked toXcfa2040andXbarc32, with genetic distances of 1.4 cM and 4.8 cM, respectively
