向日葵列当(Orobanche cumana)是一种寄生性杂草,给世界各地向日葵生产造成严重威胁。过去几十年向日葵育种家已经成功培育出部分抗列当品种,但随着新的向日葵列当生理小种的产生,育成种质抗性也会随之逐步减弱或丧失。本综述在归纳总结向日葵抗列当已有研究成果的基础上,对列当生理小种遗传毒性发展动态、种质抗性鉴定及其抗性基因遗传规律、抗列当育种趋势、向日葵转基因等方面的国内外最新研究进展及最新动态进行了概述;针对当前基因遗传及分子生物技术、抗咪唑啉酮类(IMI)除草剂作物等热点问题的研究现状进行了重点分析,提出目前向日葵抗列当育种工程中存在的问题,并就发展前景进行了展望,以期为培育和改良向日葵抗列当新品种提供便捷和实用途径。
Orobanche cumana is a parasitic weed that poses a serious threat to sunflower production around the world. Over the past few decades sunflower breeders have successfully bred partial anti-lined varieties, but with the emergence of new sunflower lined raccoon bred germplasm resistance will gradually diminish or lose. This review summarizes and summarizes the development of sunflower anti-colony based on the existing research results, the development trend of the genotoxicity of the raccoon dog raccoon dog, identification of germplasm resistance and its inheritance of resistance genes, anti-breeding tendency, transgenic sunflower The recent research progress and the latest developments at home and abroad are summarized. The current research on the current hot issues of genetics and molecular biotechnology, anti-imidazolinones (IMI) herbicide crops and so on are mainly analyzed, and the current sunflower anti- As breeding problems, and prospects for the development prospects, with a view to cultivating and improving sunflower anti-new varieties to provide a convenient and practical way.
