甘蓝型油菜含油量性状的QTL定位
Mapping QTLs for Oil Content Traits in Brassica napus L.
摘要
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.[Resuit]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.关键词
