摘要:

通过返回式卫星进行搭载,利用空间环境进行诱变育种作为现代育种的一条新途径,已成为植物诱变育种的新兴领域。我国目前在航天诱变育种方面取得了显著的成就,培育出许多新品种(系)。但同时也存在着诸多亟待解决的问题,尤其对理论研究质疑较多,甚至存在很多矛盾性的结果,阻碍了航天育种的进一步发展。综述了航天育种的诱变机理、诱变特点及对植株的影响,并着重对存在的问题进行了分析和展望。

关键词: 空间环境 植物 诱变育种 诱变机理

Abstract:

Putting up in backtracked secondary planet and using space environment to carry out mutation breeding has become a new way for modem plant breeding and a new area for plant mutation breeding. Space mutation breeding in China has gained notable achievements, and bred many new varieties (lines). But aat the same time, there still exist many problems to be solved, especially some theoretical research activities having a lot of contradictory results, which hindered the further development of space breeding. This paper reviews the mechanism of mutation breeding in space, mutagenic characteristics, its effect on plants, and carries out analysis and prospect on the existing problems.

Key words: space environment , plant , mutation breeding , mutation mechanism
