The effective strategy for controlling this disease is breeding resistant cultivar. However, to date, no wheat varieties are fully resistant to sharp eyespot, and only a few quantitative trait loci (QTLs) have been shown to be associated with sharp eyespot resistance.<h4>Methods</h4>To understand the genetic basis of this disease, a genome-wide association study (GWAS) of sharp eyespot resistance in 262 varieties from all China wheat regions was conducted.<h4>Results</h4>After cultivation for three years, only 6.5% of the varieties were resistant to sharp eyespot. Notably, the varieties from the middle and lower Yangtze River displayed higher sharp eyespot resistance thFrontiers in plant science1056935https://www.ebi.ac.uk/biostudies/studies/S-EPMC9792169biostudies-literatureIdentification of new resistance loci against wheat sharp eyespot through genome-wide association study.PMC9792169Li DJiang WZhang YGao ZWu RWu DWang JWu XGao DfalseIdentification of new resistance loci against wheat sharp eyespot through genome-wide association study.<h4>Introduction</h4>Wheat sharp eyespot caused by Rhizoctonia cerealis is a serious pathogenic disease affecting plants.
