摘　　要：利用两个水稻品种 ,在太空和 6 0 Co-γ射线条件下进行处理 ,从多方面研究和比较了它们的遗传效应。结果表明 ,太空条件下由于强宇宙辐射、高真空和微重力等的综合作用 ,水稻种子发生了深刻的遗传变异。这些变异具有遗传的性质和育种的价值 ,是一种可以利用的育种新方法。Two rice varieties were treated by space flight and by 60 Co irradiation, respectively. Their M 2 progenics were compared. The results showed that inheritable variations were induced in rice by space flight because of multiple actions of strong universe irridiation, high vaccum and microgravity. Those variations were hertiable and of breeding values. Space flight is a new way of inducing variation.
