通过卫星或其它航天器搭载农作物种子进行高空诱变，已被证明为一种行之有效的诱变育种手段（见中国航天育种研讨会文集，北京，1996）。1994年我们以籼型水稻84－01A干种子搭载94－06返回式卫星，观察了其诱变情况。回收的种子分成两份，一份培养成试管苗后种植；另一份在田间 The introduction of crop seeds via satellite or other spacecraft for altitude mutagenesis has proven to be an effective mutagenic breeding method (see China Space Breeding Symposium, Beijing, 1996). In 1994, we carried the 94-06 return satellite with dry seeds of indica rice 84-01A and observed its mutagenesis. Recycled seeds are divided into two parts, one cultivated into test tube seedlings planted; the other in the field
