摘要：

A highly leaf rust resistant genetic stock 19HRWSN-76 from CIMMYT was crossed to a susceptible variety Zhengzhou 5389 to generate F-1 and F-2 population to find out the mode of inheritance and map the resistance gene. The F-2 population was inoculated with uredosporic inoculum of physiological race FHJP of leaf rust. The 3:1 ratio of resistant and susceptible plants in F-2 suggested that the leaf rust resistance in 19HRWSN-76 is controlled by a single gene, tentatively named Lr19HRWSN-76. Relationship between the known leaf rust resistance gene Lr24 and Lr19HRWSN-76 located on chromosome 3D was established by SSR marker barc71 and STS 24-16.
