| 中文摘要: |
| 采用灰色关联分析法，对海南11份春大豆品种的产量及主要农艺性状进行分析。结果表明：春大豆品种的产量与主要农艺性状的关联顺序为单株粒重＞生育期跃主茎节数＞百粒重跃单株粒数＞单株荚数跃有效分枝数＞株高＞底荚高度。因此，在高产品种的选育上，应优先考虑单株粒重、生育期和主茎节数等指标。 |
| 英文摘要: |
| Yield and main agronomic characters of 11 varieties of spring soybean in Hainan were analyzed using the grey relation analysis method. The results showed that nine major agronomic characters related to yield were in following sequence: yield per plant> growth period> node number of main stem> 100-seed weight> seed number per plant> pod number per plant> effective branch number>plant height> pod height at bottom. Therefore, we should prioritize yield per plant, growth period, node number of main stem etc. for high yield breeding. |
