| 摘 要： | 以烤烟台烟7号与白肋烟白肋21作为杂交亲本，后代自交衍生的127个F2和F2:3家系为材料，构建了全长3 483 cM包括26个连锁群、190个标记位点的烟草遗传连锁图谱。通过一年两地各3次重复的随机区组田间试验，测定烟叶烟碱、总氯、总钾、叶长、茎叶夹角、白粉病6个重要性状，采用混合线性模型的复合区间作图法定位QTL并分析其遗传互作效应。结果检测到2个烟碱相关QTL、2个总氯相关QTL、1个总钾相关QTL、4个叶长相关QTL、茎叶夹角和白粉病相关QTL各1个，其中6个加性效应QTL和4对加加上位性效应QTL。这11个基因位点遗传效应中除加性效应外，上位性效应也具有重要作用。

| Abstract: | The agronomic traits,chemical components,and diseases are very important factors affecting the yield and leaf quality of tobacco.QTLs linked to the three aspects of traits can be used in marker-assisted selection for the yield and leaf quality improvement in tobacco.The objective of this study was to identify QTLs controlling important traits in tobacco,which could promote the basic research of molecular marker-assisted selection breeding.A population with 127 F2 and F2:3 individuals from the cross between ... |
