摘  要:
利用8个来自于普通菜豆抗白粉病基因SCAR 标记( SAU5、SS18、SF6Em3、SF12R9、SF13R10、SF18R7、SF18R15和SMe1Em5)引物组,对78份普通菜豆资源进行抗白粉病分子标记的鉴定。结果表明:在这78份资源中, SF12R9、SF13R10、SF18R7、SF18R15和SMe1Em5均无扩增带。有52份资源含有SAU5标记,66份资源含有SF6Em3标记,76份资源含有SS18标记。76份资源含有2~3个标记。该研究明确了78份参试菜豆资源所含的抗白粉病基因类型,并筛选出抗白粉病基因聚合体的参试菜豆资源。

摘  要:
Eight SCAR primer combinations( SAU5, SS18, SF6Em3, SF12R9, SF13R10, SF18R7, SF18R15 and SMe1Em5) of common bean powdery mildew resistant genes were used to check the genome DNA of 78 common bean accessions. The SCAR primer pairs of SF12R9, SF13R10, SF18R7, SF18R15 and SMe1Em5 did not amplified target bands at all; SAU5 marker appeared in 52 accessions, SF6Em3 marker in 66 accessions, and SS18 marker in 76 accessions. 2~3 SCAR markers appeared in 76 accessions respectively. The types of powdery mildew resistant genes in each of the 78 accessions have been identified, and the accessions with pyramiding powdery mildew resistance genes were selected.
