摘　　要：太空诱变育种研究是利用太空搭载等综合技术进行的诱变育种研究工作,是集空间技术、现代化农业技术以及分子生物技术于一体的跨学科的交叉新技术,是近几十年来产生的一种崭新育种技术。与传统育种方式相比,可在相对较短的时间内,大幅度提高作物产量和抗性,创造出大批优质种质资源,是缓解植物及农作物种质资源匮乏的有效途径之一,也是生物育种的重要发展方向之一。现对太空诱变育种的概念特点、生物学效应以及国内外研究进展等方面进行了全面阐述,并对未来的发展趋势进行了展望。The study of space mutation breeding was a comprehensive technologies carried by spacecraft which combined space technology,modern agricultural technology and molecular biology technology.It has been a new kind of interdisciplinary technology in decades.Compared with the traditional breeding,it could greatly improve the yield and resistance of crop germolasm resources in a relatively short period of time.The space mutation breeding technology could create a large number of high-quality germplasm resources,which was an effective way for easing plants and crops germplasm resources shortages and it was also an important development direction of biological breeding.In this paper,the concept and characteristics of the space mutation breeding,biological effects,as well as the research progresses at home and aboard were summarized,and the future development trend was prospected.
