摘要
[目的]为改良甘蓝型油菜品种与杂种优势育种提供参考。[方法]通过RAPD标记技术,分析甘蓝型油菜自交系相互间亲缘关系远近,并在此基础上构建材料的DNA指纹图谱。[结果]华东地区与西南地区的甘蓝型油菜自交系具有明显的遗传差异,分属在6个类别中,其中西南地区的材料在6大类中都有归属,个别自交系材料单独归属在一个大类,与同地区的其他材料的遗传距离较大。[结论]自交后代选系中可能包含亲本的某些优良基因,有助于引入特异种质资源和丰富的变异类型。
[Objective]The research aimed to provide references for improvement of Brassica napus inbred lines and heterosis breeding.[Method] The genetic relationship between different Brassica napus inbred lines was analyzed by the RAPD marker technology.Based on the result,the DNA fingerprinting was constructed.[Result] Brassica napus inbred lines of the east China and the southwest China had obvious genetic diversity,divided to six classes.The main materials from the southwest China distributed in the six classes.While exceptional inbred lines belonged to one big classes,differed greatly with other materials in the same district.[Conclusion] The inbred progeny strain might include valuable genes of parents,which was helpful to introduce special germplasm resources and rich variation type.
