| 摘 要： | 以早抽薹‘S-1’与晚抽薹‘G-1’为亲本，构建F1、BC1、BC2和F2群体，采用植物数量性状主基因 + 多基因混合遗传模型分析法对结球甘蓝抽薹性状进行遗传分析，并采用SLAF-BSA方法对抽薹时间进行QTL定位分析。结果显示，结球甘蓝抽薹性状是由2对加性—显性—上位性主基因 + 加性—显性多基因遗传控制；主基因 + 多基因平均遗传率是93.41%。共检测到2个QTL，分别为2号染色体上的2.31 ~ 3.09 Mb和33.57 ~ 34.40 Mb，总长度为1.61 Mb。

| Abstract: | We constructed the populations of F1，BC1，BC2，and F2 by using cabbage lines‘S-1’（early flower）and‘G-1’（late flower）as parents and adopted the plant quantitative trait major gene + polygenic mixed genetic model method to analysis the genetic model of bolting time of cabbage. Besides，we used SLAF-BSA technology to mapping the bolting time QTLs. The results showed that the bolting time fitted the model of two additive-dominant-epistatic major genes and additive-dominance polygenes. The average heritability of major genes plus polygenes was 93.41%，which indicated that bolting trait of cabbage was mainly affected by major gene inheritance. Moreover，two QTLs were detected，which located on chromosome C02 2.31–3.09 Mb and 33.57–34.40 Mb，respectively，with a total length of 1.61 Mb. |
