Abstract: The paper studied the yield-related of different hybrid rapeseed branches, pods, grain structures, using 10 hybrid rapeseed as the material by correlation analysis. The results showed that economic production presented positive correlation with the branches, pods and grains. First branch weight, pod number of secondary branches, secondary branches pod shell weight, seed weight of secondary branches, number of secondary branches, weight of secondary branches and weight of first branch impacted more significantly on the yield, number of secondary branches, weight of secondary branches, first branches weight and yield-related characters reached significant level. So when we take four components and the other agronomic characters, the choice of these 3 factors could be considered to be utilized in high yield breeding.
