| 摘要: |
| 用对应分析法对8个棉花野生种的杂种后代共83份材料的主要经济性状进行了分析。结果表明，对应分析不但揭示了材料间、性状间的相互关系，同时也揭示了性状与材料之间的相互关系；把83份材料划分为19个不同遗传差异的类群，可揭示出影响产量的主要因子是单株成铃和衣分，影响品质的主要因子是纤维强度和断裂长度。 |

| A Corresponding Analysis of Main Economic Properties of Cotton Species Hybrid Posterity |
|
|
| Abstract: |
| The main economic properties of the species hybrid posterities of 8 cotton wild varieties from 83 portion of materials were analysed.The results indicated that
the corresponding analysis method not only revealed the relationships between internal
properties and internal materials, but also the interrelationships between material and
properties.By dividing the 83 materials into 19 catagories with different hereditary features, it was indicated that the main factors affecting yields were the bolls and lint per
plant, and that the principal reasons for degrading qualities were fibre strength and
breaking length. |
