摘要
油菜开花期影响油菜的成熟期和产量,是重要的农艺性状。目前国内外学者对油菜开花期已经展开了深入研究。本文主要从模式植物拟南芥开花期的遗传调控、油菜开花期性状QTL定位、油菜开花基因克隆等方面阐述研究进展,并指出目前存在的问题和对油菜开花期性状研究进行展望,以期对开花期QTL精细定位、基因克隆和分子标记辅助选择提供理论依据。
The flowering stage of rapeseed affects the maturity and yield of rapeseed,which is an important agronomic trait.Scientists around world have been researching the flowering stage of rapeseed.This paper mainly describes the research progress from flowering regulation of Arabidopsis thaliana,types of QTL mapping populations of flowering time traits,QTL mapping and cloning of rape flowering time gene,and pointed out the existing problems and prospects for studying of early maturing traits of rapeseed.It provided a theoretical base for further QTL fine mapping,gene cloning and molecular marker-assisted selection.
