| 摘 要： | 以普通亚麻的９个品种为材料进行种子产量相关性状通径分析。结果表明，７个相关性状对种子产量的影响大小顺序为株高＞工艺长度＞单株粒数＞单株粒重＞单株结实果数＞千粒重＞主茎分枝数。千粒重相对稳定的类型中，选择植株较高、单株粒数较多者，是提高种子产量的主要途径。降低工艺长度也是提高种子产量的重要因素。在植株较高、单株粒数较多的类型中，选单株粒重较高、单株结实数和主茎分枝数多的材料可有效提高种子产量。在其它性状保持不变的情况下，选择千粒重高者也可提高种子产量，但幅度较小。

| Abstract: | The path analysis of characters relating to seed yield in flax was conducted.The seed yield is influenced by 7 correlative characters in following order:plant height>technological length> number of seeds per plant>weight of seeds per plant>number of seeded pod per plant>weight of one thousand seeds>number of branches on main stem.The main way to improve seed yield was to select materials with higher plant height and more seeds per plant.To reduce the technological length was another important way.It may improve seed yield effectively to select materials with higher weight of seeds per plant.more seeded pods per plant and branches of main stem. |
