摘要: 构建大白菜分子遗传图谱,为大白菜干烧心QTL定位和分析奠定基础。以大白菜感病品种B120和大白菜抗病品种黑227为亲本建立的DH系为作图群体,基于所筛选出的74对InDel标记和37对SSR标记构建分子遗传图谱。利用JoinMap 4.0软件,初步构建了一张覆盖基因组长度为1 004.7 cM、平均图距为9.30 cM的大白菜遗传连锁图,该图谱包含12个连锁群、108个标记位点。该图谱能有效地用于大白菜干烧心QTL定位。

Abstract: A molecular genetic map of Chinese cabbage was constructed, whose aim that the location and analysis of QTL of tipburn in Chinese.The map was constructed based on 74 InDels markers and 37 SSRs markers using DNA samples extracted from a doubled haploid population obtained through microspore culture from the F1 between two homozygous parents:B120 and Black 227.By using JoinMap 4.0 software analysis, the map consisted 12 linkage groups, included 108 genetic markers and covered 1 004.7 cM with an average distance of 9.30 cM.The map would be used effectively to QTL location of tipburn in Chinese cabbage.

Key words: Chinese cabbage, Tipburn, DH population, Genetic linkage map
