Abstract: Abstract：【Objective】Constructing the linkage map of Brassica napus L. and mapping the QTL of oil content and hull content. 【Method】F2:6 RIL population with 188 lines, crossed by GH06 as female parent and Youyan 2 as male parent，were used as mapping Population. The SRAP、SSR、AFLP and TRAP markers were used to construct the linkage map, and the composite interval mapping (CIM) was used to identify quantitative trait loci associated with oil content and hull content.【Result】300 markers were integrated into 19 groups with software JoinMap3.0. It covered 1248.5cM with a mean marker interval of 4.16cM. Eight QTL were found for oil content with the phenotypic variance explained of 5.95％～9.47％; Two for hull content with the phenotypic variance explained of 6.91％and 6.05％respectively. 【Conclusion】It was confirmed that SRAP marker was a good marker system for the construction of linkage map. The hull content has a great effect on the oil content.
