    Abstract:

    Southern rust is an important disease in maize production. A total of 903 maize accessions were screened for resistance to Southern Corn Rust in Nanning, Guangxi and Changping, Beijin from 2013 to 2015. And the SSR markers were adopted in genetic diversity analysis of the selected partially resistant materials. In Nanning, Guangxi and Changping, Beijing, both of the results showed that among the 903 germplasm, 8 inbred lines were highly resistant to southern corn rust, accounting for 0.88% of the total germplasm. Twenty-nine germplasm, including 27 inbred lines and 2 landraces was resistant to this disease, accounted for 3.2% of total accessions,
