This invention relates to molecular markers closely linked with Thanatephorus cucumeris resistance QTL, and their applications. The volumes of molecular markers gwm608, gwm88, wmc727 and gwm410.2 are 180bp, 130bp, 200bp and 300bp, respectively. The molecular markers can be used for detecting the genotypes of wheat variety CI12633 and its derived varieties or lines, and identifying Thanatephorus cucumeris resistant wheat varieties or lines. The molecular markers overcome the problems of long detection period and low efficiency faced by normal methods, and are rapid and highly efficient. Besides, the molecular markers also have such advantages as convenient resistance detection, no environmental influence, high accuracy and high efficiency. |
