自五十年代起,我国就已开展了辐射遗传育种工作,但所用的外照射源多为 X 射线、γ射线和中子源等,而电子束用于植物诱变育种和植物辐射遗传方面,则刚刚开始。当前在国际上,电子直线加速器也多用于塑料加工、涂料的辐射固化、医疗器械、辐射消毒和环境保护等方面。为了充分发挥电子束在植物遗传育种中的作用,我们从1979年下半年开始,利用国产
Since the 1950s, China has carried out radiation genetic breeding work, but most of the external radiation sources used are X-ray, γ-ray and neutron sources, and electron beams are used in plant mutation breeding and plant radiation genetics. Just started. Currently in the international arena, electron linear accelerator is also used for plastic processing, radiation curing coatings, medical equipment, radiation disinfection and environmental protection and so on. In order to give full play to the role of electron beam in plant genetic breeding, we started from the second half of 1979, using domestic
