Abstract: 【Objective】 To locate the molecular markers related to the oil and explore the genes related to the trait. 【Method】In this study, F2 population was constructed with Springfield-B and ymnm-8 as parents, and SRAP molecular markers were used to construct the genetic linkage map of Brassica napus L. 【Result】The results showed that the genetic map contained 52 marker sites with a total length of 1,039.6 cM and 15 linkage groups. The average genetic distance between the markers was 19.9 cM. The QTLs associated with oil content were analyzed and two QTLs related to oil content were obtained. QOC15 was located in the linkage group LG1: EM3ME5-EM4ME22a, and the explanatory rates were 11.23% and 4.12%, respectively, and the additive effect values were 0.48 and 3.56, respectively. The qOC1 was located in the linkage group LG1: EM9ME6-EM17ME24. 【Conclusion】Two QTL loci related to oil content were obtained, which laid a foundation for the study of oil content in Brassica napus L.

Key words: Brassica napus L.; oil content; genetic linkage map; QTL mapping

摘要: 【目的】开发与含油量相关的分子标记,发掘与该性状相关的基因。【方法】以Springfield-B和ymnm-8作为亲本构建F2群体,利用SRAP分子标记构建甘蓝型油菜遗传连锁图谱。【结果】该遗传图谱含有52个标记位点,图谱全长1 039.6 cM,含有15个连锁群,标记间的平均遗传距离为19.9 cM。分析与含油量相关的QTL位点,获得了2个与含油量相关QTL位点。其中qOC1位于连锁群LG1:EM9ME6-EM17ME24标记区,qOC15位于连锁群LG1: EM3ME5-EM4ME22a标记区间,其表型变异解释率分别为11.23%和4.12%,加性效应值分别为0.48和3.56。【结论】获得了2个与含油量相关QTL位点,为研究甘蓝型油菜含油量奠定了一定的基础。
