棉花种间杂种后代主要经济性状的对应分析

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

The main economic properties of the species hybrid posterities of 8 cotton wild varieties from 83 portion of materials were analysed.The results indicated thatthe corresponding analysis method not only revealed the relationships between internalproperties and internal materials, but also the interrelationships between material andproperties.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 perplant, and that the principal reasons for degrading qualities were fibre strength andbreaking length.
