摘　　要：经高空气球搭载的谷子个体及群体存在性状变异．Ｓｐ１植株高度比对照低６．８ｃｍ，剑叶面积比对照高２５％，穗重比对照高１６％；Ｓｐ２出现了各种各样的性状变异；Ｓｐ３大穗型株系性状相对稳定，其中Ｓｐ３～２的种子蛋白质和脂肪含量均高于对照，Ｓｐ３～５的平均穗长比对照长５．８ｃｍ，种子的Ｆｅ元素含量比对照高６１．５μｍｏｌ／ｍｏｌ，不育株败育花粉约占１／４～１／２。Character variation on millet offsprings were discovered by the radiation in the stratosphere. The experimental results showed that plant height reduced 6.8cm in Sp1; flag-leaf area and spike weight increased 25% and 16%; there was various of character variation in Sp2 , the character of larger- spike was stable in Sp3 progeny. In Sp3～2, the contents of seed protein and fatty acid raised over the control; in Sp3～5, the average spikelength increased 5.8cm and the content of Fe element in seed raised 61.5ppm compared with control. about 1/4～1/2 pollen was unmature in Sp3 sterile plants.
