This genetic map drawn by Mapmaker 3.0 containing 17 linkage groups with 75 SSR markers by using a F2 mapping population derived from the intervarietal cross of Yunyan85 × Dabaijin599 and 91 polymorphic markers identified by SSR molecular marker technique. Four QTLs related to the character of easy curing potential were detected based on this genetic map and the phenotype data by the method of composite interval mapping, which mapped on the linkage group 1, 8 and 9, respectively, with the explainable phenotypic variation of 9.26%, 8.87%, 7.57% and 7.83%. The additive effect values of the four QTLs are all positive, indicating these additive effects should come from one of the parent, Yunyan85.
