The traits of Yr5, Yr9 (1B/1R), and Yr18 genes play an important role in wheat breeding in China, and the molecular markers STS9/10 of Yr5, AF1/4, D15, 20H of Yr9 (1B/1R) and csLV34, cssfr1~cssfr5 of Yr18 were effectively tested by applying near isogenic lines under background of Avocet S and lines with known Yr genes. The results showed that the specific molecular markers of Yr5 gene STS9/10, Yr9 (1B/1R) gene AF1/4, D15 and 20H could accurately identify the corresponding resistance genes in different genetic background materials. Yr18 gene molecular marker cssfr2 could accurately detect the materials not-carrying Yr18, and detect allelic variation of Yr18 in Avocet S*6/Yr5, Avocet S*6/Yr24, and Avocet S*6/Yr27. There fore, the linkage marker STS9/10 of Yr5 gene, the molecular markers AF1/4, D15 and 20H of Yr9 (1B/1R) gene can effectively detect the target gene, and the combination of several molecular markers of Yr18 gene not only effectively detected the target gene but also identified the allelic variation of this site.
