摘　　要：运用灰色系统理论,对江苏省6个鲜食大豆新品种的株高、主茎节数、分枝数、单株荚数、标准荚个数百分率、单株荚重、每千克标准荚数、标准荚重量百分率、鲜百粒重、出仁率、初花期花叶病病指、花荚期花叶病病指、鲜荚产量13个主要性状与鲜子产量进行灰色关联度分析。结果表明,各性状与鲜子产量的关联度依次为单株荚重>标准荚个数百分率>标准荚重量百分率>鲜荚产量>出仁率>单株荚数>主茎节数>株高>每千克标准荚数>分枝数>花荚期花叶病病指>初花期花叶病病指>鲜百粒重。In this paper, 6 fresh edible soybean cuhivars from Jiangsu province were used as materials. According to ＇the grey system theory, 13 agronomic traits that affected the seed yield were analyzed. The results showed that the grey correlation degree between the soybean seed yield and each factor of yield was in order as pods weight per plant〉 the percentage of the standard number of pods〉 the percentage of the standard weight of pods〉 fresh pods yield〉 shelling percentage〉 pod number per plant〉 nodes number per main stem〉 plant height〉 the standard number of pods per kg〉 branching number〉 disease index of the mosaic leaf of the pod stage〉 disease index of karelinia during early flower stage〉 fresh 100-seed weight.
