利用“９２１００６”返地科学卫星搭载水稻种子，由于宇宙空间综合作用，通过对回收种子种植后ＳＰ＿１、ＳＰ＿２、ＳＰ＿３、ＳＰ＿４主要性状和单株生产力的田间观察和室内考种，结果表明：ＳＰ＿２群体单株间表现分离，ＳＰ＿２单株与ＳＰ＿３平均值其主要性状协方差分析，单株生产力较对照种（ＣＫ）表现极显著差异，而ＳＰ＿２、ＳＰ＿３之间无明显差异，说明利用宇宙空间处理农作物种子所产生的变异是可遗传的，通过宇宙空间处理选育农作物新品种可作为诱变育种的一种新的有效途径。
Using the “921006” backscattering satellite to carry rice seeds, the field observations and laboratory tests of the main characters of SP_1, SP_2, SP_3 and SP_4 and plant productivity after the seeds were planted were carried out due to the combined effect of cosmic space. The results showed that: The results showed that there was significant difference between single plant and CK, but no significant difference between SP_2 and SP_3, which indicated that the use of space-time processing of crops Variation produced by seeds is heritable. Breeding new varieties of crops through cosmic space can be used as a new and effective way of mutation breeding.
