通过对２０个油菜品种花器大小或多少与经济性状、主茎绿叶数、５ｃｍ和１０ｃｍ长以上分枝数与有效分枝的变异和相关分析表明：花蕾的长与果长,每果粒数和花瓣宽,花瓣长与每果粒数,花瓣宽与每果粒数,着花密度与着果密度,主序蕾数与主序果数,主茎绿叶数、５ｃｍ和１０ｃｍ长以上分枝数与有效分枝数,呈显著或极显著正相关,花期对这些性状的选择极为有效．
Variations and correlations among the size and number of flower organ,yieldcomponents,number of green leaves on main stem,numbers of branches over 5 and 10 cm.long and useful branches of 20 rapeseed cultivars were studied. Results showed that correla-tions were signficant or extremely significant between flower bud length and pod length,average flower number per cm. and average pod number per cm,flower bud number on maininforescence and pod number on main inflorescence,number of green leaves on main stem ornumber of branches 5 or 10 cm long and number of useful branches.Selections for those cha-racters at flowering were very effecient.
