| 摘 要： | 种胚叶绿素含量是影响菜子油加工和销售的重要指标。关于种胚叶绿素的遗传特性还缺乏研究。本文以重庆市油菜工程中心构建的甘蓝型黄子与黑子油菜重组自交系群体为材料,2007年分别在重庆市北碚区和万州区两个实验基地种植,利用本实验室已构建的遗传连锁图谱为基础,采用复合区间作图法(C IM)分析种胚叶绿素的QTL。结果共检测到10个QTL,分别位于第1、2、5、8、21和25连锁群,单个QTL解释表型变异的4.04%～8.50%。研究结果表明胚中叶绿素表现为多基因控制的数量性状,基因表达受环境影响较大。

| Abstract: | Embryonic chlorophyll content affects processing and marketing quality of rapeseed oil,but its genetic features are still unknown.The objective of this study was to identify QTL controlling embryonic chlorophyll content in Brassica napus.A recombinant inbred line(RIL) population with different seed color was grown at Beibei and Wanzhou in Chongqing in 2007,the QTLs for embryonic chlorophyll content were identified using the composite interval mapping(CIM) method and the genetic map constructed.A total of 10... |
