高新技术在棉花育种上的应用及进展

Applications and Progress of Hi-technology on the Cotton Breeding

棉花生物技术在基因工程方面取得了较大进展。基因工程中,随着农杆菌介导法、花粉管通道法、基因枪轰击法等技术的突破,在棉花抗病虫害、抗除草剂等方面的育种获得成功,相应的新品种已开始了商业化生产。中国棉花生物技术在抗棉铃虫等方面达到世界领先水平。作者结合该实验室的研究工作,综述了生物技术在中国棉花育种中的应用进展,分析了中国棉花生物技术存在的主要问题,提出了相应的发展对策。

Cotton biotechnology is achived mainly in genetic engineering.Cotton genetic engineering is succeeded due to progresses of Agrobaterium tumeficiens mediated method, particle bombardment method and pollen-tube pathway.Many transgenic cotton lines,which are acquired different forein genes including pest resistant gene, herbicide resistant gene, are applied in cotton breeding, subsequently,new varieties are commercialized in market. In China, it is advanced on transgenic bollworm resistant cotton in the world.Based on the research in our laboratory, this article indicates the applications and progress of biotechnology on the cotton breeding,analyzes the main problems in cotton biotechnology, and advises its developing strategy and suggestions.
