对芥菜型油菜单株产量等９个主要农艺性状进行了灰色关联度分析，结果表明单株产量与其相关性状的关联序依次为：ｒ０７（千粒重）＞ｒ０５（全株有效角果数）＞ｒ０２（第一有效分枝部位）＞ｒ０４（主花序有效长度）＞ｒ０６（每角果粒）＞ｒ０１（株高）＞ｒ０８（角果长）＞ｒ０３（第一有效分枝数），并明确了各性状之间的相互关系及对单株产量的影响程度，为油菜育种提供了理论依据。
The results showed that the order of correlation between single plant yield and its related traits was r07 (1000-grain weight)> r05 (whole plant effective pod)> r02 (First effective branch)> r04 (effective length of main inflorescence)> r06 (fruit per corner)> r01 (plant height)> r08 (long horn)> r03 The relationship between the traits and the degree of impact on the yield per plant provides a theoretical basis for rapeseed breeding.
