摘要: 在已构建的结球甘蓝AFLP、SSR和SRAP标记高密度遗传图谱的基础上,运用MapQTL 4.0软件对结球甘蓝F2群体抽薹、开花时间两性状分别进行QTL定位和分析。最终检测到2个控制甘蓝抽薹时间性状的QTL(qbt-3-2、qbt-9-1),以及一个同开花时间性状相关的QTL(qft-9-1),分别位于连锁群LG3与LG9上,这3个QTL均为增效位点,共解释甘蓝抽薹、开花时间性状变异的17.5%,22.7%;同时得到与QTLs共分离的2个分子标记E46M52-5、me26-em13-1,均可作为辅助选育甘蓝耐抽薹品种的标记使用,这将为结球甘蓝耐抽薹品种的选育提供理论依据。

Abstract: Based on the Cabbage genetic linkage map which had been constructed previously, QTL mapping and analysis related to bolting and flowering time in the individuals of F2 were conducted using MapQTL 4.0.Two QTL(qbt-3-2,qbt-9-1)located on LG3 and LG9 controlling the traits of bolting time and one QTL(qft-9-1)located on LG9 controlling the traits of flowering time in cabbage were detected. The three QTLs are all the sites of additive effect,17.5%,22.7%of variation that can be explained respectively. Meanwhile,two molecular markers(E46M52-5,me26-em13-1)corresponding with the QTLs could be used for M-AS of breeding for bolting tolerance. It will pro-vide the basis of theoretical for the resistant bolting varieties breeding.
