摘　　要：利用相关分析和灰色关联度分析法对蚕豆(Vicia faba L.)主要农艺性状进行了研究,探讨了蚕豆产量及主要农艺性状间的关系。结果表明,各性状与小区产量的关联度由大到小的顺序为单株产量(0.844 3)、单株荚数(0.835 6)、单株粒数(0.763 1)、株高(0.759 8)、百粒重(0.694 1)、荚长(0.652 5)、生育期(0.620 6);相关分析表明,小区产量与单株产量和单株荚数均呈极显著正相关,两种分析方法结果一致,因此,可以通过提高单株产量和单株荚数来提高蚕豆产量。The correlation coefficient and correlative degree between yield and each of eight agronomic traits of twelve broad bean varieties was studied by correlation analysis method and the grey correlation method. The results showed that the values of the correlative degree between yield and main agronomic traits among different varieties from high to low were sequenced as follows：yield per plant（0.844 3）,number of pods per plant（0.835 6）,seed number per plant（0.763 1）,plant height（0.759 8）,hundred-grain weight（0.694 1）,pod length（0.652 5）,growth period（0.620 6）. The results of two analysis methods all indicated that the yield was significantly positive correlated with the number of pods per plant and yield per plant. So,we could increase the yield of broad bean by raising yield per plant and number of pods per plant.
