摘要： 基于MATLAB分析了油菜若干性状之间的关系，从产量性状入手，性状重要性的大小顺序是：主茎总叶数＞根茎粗＞株高＞单株产量＞主茎绿叶数＞一次有效分枝数＞二次分枝数＞单株有效角果数＞每角果粒数＞千粒重，这10个性状除每果粒数与千粒重外，前8个性状与产量均达到显著正相关，通过以上分析以期为油菜栽培管理提供理论与实践指导。

Abstract: Analyzed the relation among some characters of B.napus based on MATLAB, according to the yield character, the sequence of the characters importance was: leaves on main stem>the diameter of root collar>the height of plant>the yield of each plant＞green leaves on main stem>effectively primary branches>secondary branches>corniform pods on each plant>grains on each pod＞the 1000-seed weight, the former 8 characters was extreme significantly correlated with the yield, except for the grains on each pod and the 1000-seed weight. I hope that it can provide theory and practice instruction in B.napus cultivation by them.
