Abstract
The soybean Recombinant Inbred Lines(RIL), including 133 lines, from the cross Wan82-178 x Tongshan-baopihuangdoujia were used as experimental materials in this study. Based on the linkage map constructed with Single Sequence Repeat(SSR) markers using this RIL population, the software Cartgrapher(V.2.0) and the composite interval mapping were employed to identify quantitative traits loci(QTL) associated with oil content of soybean in 2004 and 2005. It was found that the results of mapping QTL for the oil content were similar for these two years. They were both mapped near satt331 on linkage group wt-11, and they could be used to explain 13.95% and 15.01% of the total variation of the oil content, respectively. In addition, the software QTL Mapper 1.6 was applied to detect QTLs related to oil con-tent in two years. The result indicated that the QTL related to oil content was still mapped near satt331 on linkage group wt-11.
