摘要： This study used SSR and AFLP markers to construct the genetic linkage map of Reyan5-11xPR107 population, integrated the published genetic linkage map and utilised the integrated map to perform QTL mapping of rubber yield-related traits. A genetic map consisting of 132 molecular markers (88 SSR and 44 AFLP markers) was constructed, and a joint map consisting of 143 molecular markers (99 SSR and 44 AFLP markers), which contained 19 linkage groups covering the rubber tree genome of 1298.5 cM, each linkage group containing 2-40 Mark, the average distance between the marks is 9.08 cM. Under the conditions of LOD >= 2.5, it was detected 2 QTLs related to girth, 3 QTLs related to dry rubber content, and 3 QTLs related to dry rubber yield per tree, 4 QTLs related to the unit secant length dry rubber yield, 5 QTLs related to the number of conducting phloem laticifer and 4 QTLs related to the number of yellow phloem laticifer.
