摘要：

为了探讨大豆各主要农艺性状对单株产量影响的主次关系，以黑龙江省第二积温带种植的6个大豆品种为试验材料，应用灰色系统理论的关联度分析法对与大豆单株产量相关的8个性状进行关联分析。结果表明：大豆单株产量相关性状的灰色关联度大小依次为单株粒数>主茎分枝数>单株有效荚数>百粒重>底荚高度>株高>生育期>主茎节数，与单株产量最为密切相关的性状是单株粒数，其与产量的关联度为0.42，其次是主茎分枝数，与产量的关联度为0.39，主茎节数影响相对较小。因而，在大豆品种选育过程中，应注重单株粒数多和主茎分枝数多的品系选育。

Abstract:

To explore the effects of major agronomic traits on the per plant yield of soybean, the grey relation analysis was used to analyze the relationship of the agronomic traits with per plant yield of 6 soybeans in the second Jiwendai of Heilongjiang area. The results showed that, the agronomic traits of high grey relation degree with per plant yield ordinarily were the seed number per plant > effective branch number > effective grain number per plant > 100-seed weight > pod height at bottom > plant height > growth period > stem internodes number, the seed number per plant had the largest influence to per plant yield, the correlation of per plant yield was 0.42, the effective branch number had a second influence to per plant yield, the correlation of per plant yield was 0.39, the number of internodes influence was relatively minor. When breeding variety was prior to choose single plant, the seed number per plant and the effective branch number were higher.
