- 摘要:
- 采用44个远缘杂交大豆后代为材料,对植株的倒伏级别和农艺性状进行了相关分析、灰色关联度分析,并分析了亲本配合力。通过分析大豆倒伏与相关农艺性状的关系,试图为抗倒伏大豆育种亲本选配提供理论依据。结果表明:44个F3代远缘杂交大豆株系中,植株倒伏性分离广泛,组合间有显著性差异。亲本中俄亥俄当代品种以及辽宁当代品种中部分品种配合力较高,有利于抗倒伏品种的选育。株高、茎粗、分枝数和植株重量平衡点是影响倒伏的主要因素。关
- Abstract:
- Lodging is one of the common problems that are difficult to manage in high yielding culture of soybean,which not only affects the soybean yields but also affects the seed quality.In this experiment,the lodging scores and agronomic traits in F3generation of 44 crosses were measured.Correlation analysis and grey related degree analysis were used to analyze the relationship between soybean lodging scores and related agronomic traits.Combining ability has been measured on the parent lines.The relationship between soybean lodging and the related agronomic traits was studied in order to offer the information for the parent selection in the soybean breeding of lodging resistance.The results indicated that soybean lodging scores separated widely in the F3generation of 44 crosses.Significant differences existed between crosses.Some of current Ohio cultivars and current Liaoning cultivars had higher combining ability. These parents were beneficial to the soybean lodging-resistant breeding.Plant height,stem diameter,branch number and the balance point of plant weight were the main factors of affecting soybean lodging.
