油菜(Brassica napus L.)矮化研究进展

油菜(Brassica napus L.)是具有重要影响的油料作物。通过杂交育种在油菜上的运用,获得了相较于旧品种在生活力、生长势、抗逆性、适应力、产量、品质等方面具有更大优势的新品种,但同时也带来了油菜倒伏与机械化生产率无法提高等问题。水稻和小麦相关的矮化研究与应用是绿色革命的重要组成部分,这为人们改良油菜品种提供了新的思路。对于油菜倒伏和提高油菜机械化生产率等急需解决的问题,油菜矮化育种成为了解决问题的关键。本研究围绕甘蓝型油菜矮化基因的遗传特点、基因定位、矮化机制等方面的研究情况进行综述,为进一步利用油菜矮化基因提供参考。

The Research Progress on Dwarfing Trait of Brassica napus L.

Brassica napus L.is an oil crop which has importan tinfluences.The use of crossbreeding in rape has obtained new varieties with greater advantages in terms of viability,growth potential,stress resistance,adaptability,yield and quality compared with the old varieties.Correspondingly,it also caused problems such as the lodging of rape and the inability to increase mechanization productivity.The research and application of dwarfing related to rice and wheat is an important part of the green revolution,which provides a new idea for people to improve rapeseed varieties.Dwarf breeding of rape has become the key to solving the problem,such as the lodging of rape and the improvement of mechanized productivity of rapeseed.In this study,the research on the genetic characteristics,gene mapping and dwarfing mechanism of Brassica napus dwarfing genes was reviewed,to provide a reference for further utilization of rapedwarf genes.
