This paper studies QTL (quantitative trait locus) resistance to Sharp Eyespot in wheat using a genetic population of the recombinant inbred line (RIL) hybridized from Niavt 14 and Xuzhou 25. Based on three-year phenotypic data and a resultant RIL genetic map, three QTLs in total associated with Sharp Eyespot resistance were detected. Two out of the three loci were detected on chromosome 2B, namely Qses.jaas-2b1 and Qses.jaas-2b2, of which Qses.jaas-2b1 accounted for 5.46 and 8.56% of the phenotypic variation in the field after inoculation in two successive years and Qses.jaas-2b2 accounted for 6.04, 8.10 and 12.92% after field inoculation for three successive years. A further QTL for resistance gene named Qses.jaas-7d was detected on chromosome 7D in addition to the two on 2B and this exceeding 11.25% of the phenotypic variation. These results indicate that QTLs associated with Sharp Eyespot possibly exist on the linkage groups of chromosomes 2B and 7D in wheat and lay the foundation for further research of QTL resistances to Sharp Eyespot in wheat.
