Objective of the study is about to detect quantitative trait loci (QTLs) for traits related to yield of latex such as Yield for plant and Size of laticifer of rubber tree. F1 population derived from crosses of the rubber tree cultivars Reyan88-13×IAN873 was used for QTL analysis. Data of trait about Yield for plant, Dry rubber content (DRC), Line of laticifer, Number of laticifer and Size of laticifer were collected and recorded. QTLs were detected by Composite interval mapping ( CIM) using FsQtlMap 1.0 based on the linkage map constructed with SSR markers. The results showed, the skewness and kurtosis of these traits were to conform to normal distribution except Number of laticifer, the mean and variance of each trait has great changes; the coefficient of variation of yield for plant maximum, the order is Yield for plant > Number of laticifer > Line of laticifer > Size of laticifer > Dry rubber content. The presence of five main-effect QTLs which are related with yield for plant was detected when LOD threshold was greater than 2.5, which could explain 71.3%，69.1%，68.3%，64.4% and 62.9% population variation respectively. Three main-effect QTLs which were related with Number of laticifer was detected, which could explain 84.5%，81.3% and15.4% population variation respectively. There were no effect QTLs related with the other traits.
