| 摘 要： | 文章分析了油用亚麻杂交后代株系的农艺性状对产量的贡献，主要考察了来自F578个油用亚麻株系的主要农艺性状与产量的关系。相关分析显示，F5中有6对性状达显著或极显著相关。对F5杂交种的7个农艺性状按最短距离法进行聚类分析，结果表明可分为4类；通过进行主成分分析，分别选取能代表全部遗传信息85％以上的4个主成分，并对各个性状在相应主成分中的贡献率进行分析，F5应选择单株粒重较大，果球数较多 、株高、分枝数和分茎数适中的材料。 |

| Abstract: | The yield contribution of the agronomic characters could be a guide for breeding selection. 78 plant lines from linseed F5 were investigated on 7 main agronomic characters （height, stem number, fabric length, ball number, seed number per ball and kernel weight per plant）. The correlation analysis showed that 6 pairs of characters had reached significant level in F5. The F5 can be divided into 4 types by the shortest distance cluster analysis. By the analysis of principle component, 4 main contents were selected in F5 that contributed 85% genetic information. As a result, we should choose the high seed weight per plant, more ball number per plant and height, stem number were better on F5 progenies linseed. |
