Keyword:  玉米高粱分子标记RAPD;
Abstract: 以玉米丹2100和高粱辽杂10号的可见叶片为材料,应用RAPD筛选技术,对玉米、高粱基因进行分子标记.主要结果如下:(1)对玉米丹2100和高粱辽杂10号叶片总DNA提取纯化的方法进行优化,确定提取总DNA的最佳方法.即CTAB法.(2)初步建立了玉米丹2100和高粱辽杂10号RAPD反应体系,并确定了RAPD反应体系中最佳的引物种类及PCR扩增的最佳反应条件,获得了稳定高效的RAPD扩增结果及多态性较好的DNA.(3)应用RAPD技术筛选14个随机引物,共扩增出45条谱带.A2、G4、Y13分别扩增出3条差异谱带分别为OPG-04800、OPA-02450、OPY-13500.
