基于MATLAB分析油菜若干性状之间的关系

Analyzing the Relation among Some Characters of B.napus Based on MATLAB

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。

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.
