摘　　要：对萝卜(Raphanus sativus L.)抽薹和开花性状的基因进行了定位研究,挖掘了调控抽薹开花的候选基因。主要结果如下:利用已构建的高密度遗传图谱,通过对F2︰3家系的抽薹和开花性状的初步定位,检测到两个QTL位点与萝卜的抽薹开花相关。通过萝卜基因注释分析和亲本间的基因序列比对分析,检测出5个基因与萝卜抽薹和开花性状相关,其具体作用还需进一步验证。The late-bolting genes in radish were localized,and the candidate genes regulating flowering were explored.The main results are listed below:a high-density genetic linkage map was constructed and two QTL loci related to flowering and bolting were detected.Based on radish gene annotation and gene sequence alignment analysis,we detected five genes with the sequence variation between the parental lines,indicated those genes associated with bolting and flowering in radish.However,the detailed functions of the candidate gene during the radish bolting and flowering need further studies.
