转基因抗虫棉后时代棉花科技问题思考

On the Cotton Researches Behind the Period of Transgenic Insect-Resistant Cotton

简述我国转基因抗虫棉研发的意义,分析转基因抗虫棉成功产业化以来棉花科技本身和生产上的基本问题,指出转基因抗虫棉促进了我国棉花生产高产稳产的发展,但是发展中也遇到了一系列的新问题,如抗虫资源的过度使用,遗传背景的匮乏,次生害虫的演变,农业现代化的新要求等。分析转基因抗虫棉后时代我国棉花科技取得新的重大突破的可能性。指出棉花科技要坚持生物技术为先导,在超高产的前提下,以品质改良和综合抗性为突破口,再创棉花生物技术研发的高峰,促进棉花生产再上新台阶。

In our country, successful commercialization of the transgenic insect-resistant cotton promote cotton production of high and stable, but it also bring a series of new problems, excessive use and extremely narrow of the insect-resistant cotton resources, target insect shift in cotton field, and new challenge from agriculture modernization. Based on these situations, the development of cotton science and technology must be directed by genetic technology and focus on super-higher-yield, and fiber quality improvement and comprehensive stress-tolerance meanwhile. So that, the cotton researches and production can creates a new breakthrough in the new period.
