| 摘 要： | 应用相关性和灰色关联度方法分析了黄淮海地区79份夏大豆的农艺性状与产量的关系,结果表明：在无限生长型大豆中,产量与有效分枝数、单株粒数呈极显著正相关;与产量关联度较高的农艺性状由大到小的顺序依次为有效分枝数、单株粒数、单株粒重、单株荚数和生育期。在亚有限生长型大豆中,产量与单株粒重呈极显著正相关,与茎粗呈显著正相关;与产量关联度较高的农艺性状由大到小的顺序依次为单株粒重、单株粒数、每荚粒数、单株荚数和茎粗。在有限生长型品种中,产量与生育期、茎粗间呈极显著正相关,与单株粒重、百粒重间呈显著正相关;与产量关联度较高的农艺性状由大到小的顺序依次为生育期、茎粗、单株粒重、有效分枝数和底荚高度。以亚有限和有限生长型为主的黄淮海地区夏大豆在进行单株选择时,应根据其不同的结荚习性而有所侧重。

| Abstract: | The correlation and grey relation analysis were used to analyze the relationship of the agronomic traits with yield of 79 summer soybeans in the Huanghe-Huaihe-Haihe area.The results showed that the yield had extremely significantly positive correlation with the effective branch number and seed number per plant,and the agronomic traits of high grey relation degree with yield ordinally were the effective branch number,seed number per plant,seed weight per plant,pod number per plant and growth period in the i... |
