| 摘 要： | 利用高空搭载粳稻品种“中作59”，处于海拔30-35km的高空，8h后回收种植，以后再用γ-射线进行处理，其后代变异类型更为丰富，变异频率增加，从中选育出了很多有利用价值的优良新种质，通过广泛测交、试种、区试、测产，选配出了一个优质、高产的两系杂交水稻新组合-培两优721。本文介绍了该组合的选育经过、组合的特征特性，并探讨了育种的体会及对高空诱变的作用机理。

| Abstract: | The air dried seeds of Japonica rice variety "Zhongzuo 59" were carried by high space balloon (in 30～35km of the sealevel selevation, 8 hours). And also irradiation by the r rays. The results of investigation to the space mutation showed that through the selection and the testators have bred many good moutons and a better combination of rice-"Pei liangyou 721". The experience of the rice and the mechanism of the space mutation one discussed in this paper. |
