以凤豆14号、苏03021、启豆2号等12个秋播蚕豆品种为参试材料，考察了生育期、株高、荚长、单株夹数、单株粒数、百粒重和单株产量等7个主要性状之间的相关关系，并通过通径分析建立了单株产量（Y）的线性回归方程。结果表明，7个农艺性状间存在复杂的相关关系，其中单株荚数与单株产量之间表现出极显著的正相关性，而生育期与单株产量之间表现出显著的负相关性；各性状对单株产量的直接贡献率由高到低依次为单株荚数＞荚长＞株高＞生育期＞百粒重＞单株粒数；单株产量（Y）的线性回归方程为：Y=-8.423＋1.281X4＋1.757X3；单株荚数（X4）、荚长（X3）被保留在最优方程中。

The correlation and path analysis of 7 agronom ic characters of 12 autumn broad bean varieties from the evaluation and selection experim ents ofautum n broad bean in 2012 to 2013.The results show thatthe relevantrelationships betw een 7 m ain agronom ic characters are complex.The yield per plantw as significantly positive correlated w ith the num ber of pods per plant and negative correlation w ith grow th stages.The num berofpods perplantand pod length w ere significantly negative relationship .The num berofseeds perplantw as significantly negative correlation w ith the hundred grain w eight.The directcontribution ofagronom ic traits to yield perplantw as in the follow ing order:pod num berperplant>pod length >Plantheight> G row th period>H undred-grain w eight> seed num berperplant.
