A molecular marker, primer group, kit for identifying sorghum resistant or susceptible to head smut and application thereof

Abstract

The present application is suitable for the technical field of sorghum fusarium head blight identification, and provides a molecular marker for identifying sorghum resistance or susceptibility to fusarium head blight, comprising a molecular marker 6Sam72772 and / or Tx430508; the molecular marker 6Sam72772 can be a 126bp DNA fragment and a 122bp DNA fragment, the nucleotide sequence of the 126bp DNA fragment is shown as SEQ ID:5, and the nucleotide sequence of the 122bp DNA fragment is shown as SEQ ID:6; the molecular marker Tx430508 is a 720bp DNA fragment, and the nucleotide sequence is shown as SEQ ID:7. The present application also provides related primer groups, kits, and methods for identifying sorghum resistance or susceptibility to fusarium head blight. The present application provides the molecular markers 6Sam72772 and Tx430508, which can accurately identify or assist in identifying sorghum resistance or susceptibility to fusarium head blight.
