520			_aStripe rust, caused by Puccinia striiformis f. sp. tritici, is a devastating disease of common wheat (Triticum aestivum L.) worldwide. Deployment of wheat cultivars with adult-plant resistance (APR) is the most environmentally friendly and economical way for controlling this disease. In the present study, 1,136 SSR markers were used to map QTLs for APR to stripe rust in two F3 populations with 255 and 252 lines derived from the crosses Libellula/Huixianhong and Strampelli/ Huixianhong, respectively. Composite interval mapping detected five QTLs for APR in Libellula, designated QYr.caas-2DS, QYr.caas-4BL, QYr.caas-5BL.1, QYr.caas- 5BL.2 and QYr.caas-7DS, respectively, explaining from 2.6?35.0% of the phenotypic variance. The QTLs QYr. caas-4BL, QYr.caas-5BL.1 and QYr.caas-7DS were also detected in Strampelli. Three interactions between different pairs of QTLs accounted for 6.1-35.0% of the phenotypic variance. The QTL QYr.caas-7DS flanked by markers csLV34 and Xgwm295 showed the largest effect for resistance to stripe rust. Sequence analyses confirmed that lines with the QYr.caas-7DS allele for resistance carried the resistance allele of Lr34/Yr18/Pm38. SSR markers Xgwm165 and Xgwm149, Xwmc415 and Xwmc537, and csLV34, were closely linked to QYr.caas- 4BL, QYr.caas-5BL and QYr.caas-7DS, respectively. These markers could be used for marker-assisted selection in wheat breeding.
