摘要: 以4个大白菜品种和4个结球甘蓝品种为试材,对位于芸薹属结球甘蓝C基因组9个连锁群的458个InDel标记进行PCR筛选,筛选出286个结球甘蓝相对于大白菜的特异InDel标记,其中位于C01连锁群31个,C02连锁群45个,C03连锁群54个,C04连锁群24个,C05连锁群22个,C06连锁群20个,C07连锁群32个,C08连锁群34个,C09连锁群24个。利用结球甘蓝C02连锁群特异InDel标记对实验室创建的大白菜—结球甘蓝易位系自交后代进行了初步鉴定,明确了外源甘蓝染色体片段的物理位置在18 096 729 ~ 18 786 494 bp之间的689 764 bp区域内。

Abstract: A total of 458 InDel markers derived from 9 linkage groups of cabbage were screened on four cabbage and four Chinese cabbage varieties by PCR amplification. The results showed that 286 InDel markers were specific on cabbage compared with Chinese cabbage,31 of them on linkage group C01,45 of them on linkage group C02,54 of them on linkage group C03,24 of them on linkage group C04,22 of them on linkage group C05,20 of them on linkage group C06,32 of them on linkage group C07,34 of them on linkage group C08,and 24 of them on linkage group C09. The inbred progeny of one Chinese cabbage-cabbage translocation line developed by our laboratory was identified preliminarily by specific InDel markers on linkage group C02. The physical location of exogenous cabbage chromosome fragment was in the 689 764 bp region from the 18 096 729 bp to 18 786 494 bp.

Key words: Chinese cabbage, cabbage, InDel marker, translocation line, linkage group
