【摘要】 以8个结球甘蓝品种和7个大白菜品种为试材,利用23对SRAP引物,筛选结球甘蓝相对于大白菜特异的SRAP引物。结果表明,18对引物在大白菜和结球甘蓝间表现多态性,可以区分大白菜和结球甘蓝不同品种。利用筛选出的18对SRAP引物对部分大白菜-结球甘蓝异附加系进行了鉴定,结果表明,其中6对引物P53、P86、P93、P121、P123和P142可以鉴定异附加系AA+2C1、AA+C3、AA+C5、AA+C7和AA+C8。大白菜-结球甘蓝异附加系特异SRAP标记的建立,为开展大白菜-结球甘蓝易位系的鉴定奠定了基础。更多还原

【Abstract】 Eight cabbage cultivars and seven Chinese cabbage cultivars were used as materials to screen specific SRAP markers for cabbage compared with Chinese cabbage using 23 primers in this study.The results showed that 18 primers performance polymorphism between Chinese cabbage and cabbage.The Chinese cabbage-cabbage alien addition line was identified by 18 screened primers,and the results showed that P53,P86,P93,P121,P123 and P142 primers can identify disomic alien addition lines AA+2C1,monosomic alien addition lines AA+C3,AA+C5,AA+C7 and AA+C8.It laid a foundation to further identify Chinese cabbage-cabbage translocation lines.更多还原
