摘要:

利用10 个普通菜豆抗锈病基因SCAR 标记(SK14 、SA14 、SI19 、SBC6 、SAD12 、SAE19 、UR11-GT2 、KB126 、SF10 和SBA8) 引物组,对78 份生产和研究中常用的普通菜豆资源进行了抗锈病分子标记鉴定。在这78 份资源中,SA14 和KB126 标记引物扩增无特异性,SI19 和SAD12 无扩增带。其中,8 份资源含有SK14 标记,23 份资源含有SBC6 标记,28 份资源含有SAE19 标记,5 份资源含有UR11-GT2 标记,62 份资源含有SF10 标记,76 份资源含有SBA8 标记。含有2-5 个标记的资源共67 份。明确了78 份参试菜豆资源所含的抗锈病基因类型,表明含有多个抗锈病基因的菜豆资源较为常见。

Abstract:

Ten SCAR primer combinations(SK14 、SA14 、SI19 、SBC6 、SAD12 、SAE19 、UR11-GT2 、KB126 、SF10 and SBA8) of common bean rust resistant genes were used to check the genome DNA of 78 common bean accessions. The SCAR primer pairs, SA14 and KB126, amplified bands without difference among all the tested accessions ;SI19 and SAD12 were not amplified target bands at all ;SK14 marker appeared in 8 accessions, SBC6 marker in 23 accessions, SAE19 marker in 28 accessions, UR11-GT2 marker in 5 accessions, SF10 marker in 62 accessions, and SBA8 marker in 76 accessions. 2-5 SCAR markers appeared in 65 accessions respectively. The types of rust resistant genes in each of the 78 accessions have been identified, and we found common that several rust resistant genes aggregated in one common bean accession.
