| Wheat sharp eyespot caused by Rhizoctonia cerealis and wheat powdery mildew caused by Blumeria graminis are two of the serious diseases in China, which have resulted in great loss of wheat grain yield. To map and localize resistance QTLs associated with both diseases using quantitative trait loci (QTLs) analysis can contribute to providing theoretical guide to breeding for disease resistance and the basis on which molecular marker-assisted selection can be implemented.To our knowledge, no QTLs for sharp eyespot resistance have been localised in wheat, and only a few studies have been published so far localised QTLs for residence to powdery mildew.Therefore, screen resistance germplasm and preliminary analysis of resistance mechanism to Rhizoctonia cerealis were carried out. Genetic linkage map of (Wenmai6xShanhongmai) recombinant inbred lines was constructed using SSR and AFLP markers. Analysis of resistance QTL associated with diseases caused by Rhizoctonia cerealis and Blumeria graminis using population derived from the cross of (Wenmai6xShanhongmai) and (Opata85> |
