绿豆单株产量与主要农艺性状的灰色关联度分析

为探讨绿豆主要农艺性状对单株产量影响的主次关系，以15 个绿豆品种为试验材料，采用灰色关联度分析法，对绿豆7 个农艺性状与单株产量的关联度进行统计分析。结果表明：各性状因子与单株产量的关联度由高到低排序为单株荚数、株高、主茎节数、百粒重、单荚粒数、主茎分枝、生育期。因此，在山西高产绿豆新品种选育时，应首先注重单株荚数和株高。

Grey Relation Analysis Between Main Agronomic Traits and Plant Yield of Mung Bean

To explore the effects of major agronomic traits on the yield per plant of mung bean, the grey relation analysis was used to analyze the relationship between the agronomic traits and yield of 15 mung bean varieties. The results showed that major agronomic traits were related to yield per plant in the following sequence: pod number per plant＞ plant height＞ main stem node＞ 100-seed weight＞ the seed number per pod＞ branch number of main stem＞ growth period. Therefore, the pod number per plant and plant height should be taken into consideration first in variety breeding and selection in Shanxi Province.
