摘要: 针对目前甘蓝型油菜Pol CMS、新型萝卜胞质Ogu CMS、新型甘蓝型油菜CMS鉴定过程中,存在必须从orf138orf222orf224 3种引物中选用2对引物进行分子标记互相验证鉴定的缺点。以开发快速鉴别新型甘蓝型油菜CMS的分子标记为目的,选取含有Pol CMS的CMS-AQ29和含有新型甘蓝型油菜CMS的CMS后36高的2个材料基因组DNA为模板,通过引物orf222进行PCR扩增,经测序对比2种类型细胞质雄性不育系的核苷酸序列差异,确定主要差异区域为180~210 bp。通过orf222上游引物末端T/G碱基的错配,设计开发了快速鉴定新型甘蓝型油菜CMS的专用引物O-2,该引物可扩增出470 bp的核苷酸序列,而不含有新型甘蓝型油菜CMS的材料则不能扩增出核苷酸序列,具有能一次性快速鉴定出含有新型甘蓝型油菜CMS不育基因材料的特点。利用该引物对转育了新型甘蓝型油菜CMS的材料CMS-D571、CMS-D574及对应的保持系D571、D574分别进行了鉴定,证实雄性不育系CMS-D571、CMS-D574为转育了新型甘蓝型油菜CMS的雄性不育系,结果表明该方法稳定可靠。

Abstract: At present, in the identification process of Pol CMS, Ogu CMS and New Brassica napus CMS, two pairs of primers must be used for molecular marker screening from orf138, orf222 and orf224. In order to develop a new type of molecular markers for rapid identification of New Brassica napus CMS, PCR amplification was carried out by orf222 that based on genomic DNA of CMS-AQ29 and CMS Hou36gao which respectively contained Pol CMS and New Brassica napus CMS.The results showed that the main difference genomic DNA between the two varieties was from 180 to 210 bp. A special primer of New Brassica napus CMS was designed and developed by T/G base-based mismatch on the end of the orf222 upstream primer terminal. It was named O-2. It could identify male sterile lines with New Brassica napus CMS immediately, 470 bp nucleotide sequence could be amplified,but nucleotide sequence could't be amplified in other resources without New Brassica napus CMS. The defect was solved that identification of male sterility must be pairs of primer. This method was resulted that is stable and reliable, the CMS-D571 and CMS-D574 are successfully identified by using this method that including New Brassica napus CMS from D571, D574, CMS-D571 and CMS-D574.
