１９８７ 年以来，中国先后将３００ 多个品种５０ 多种农作物种子，搭载返回卫星和高空气球。选育出的品（系）种主要有：丰产、抗病、优质的水稻新品系，能恢复籼稻不孕系的粳稻恢复系材料，果大５００ ｇ 以上的青椒新品，抗病、优质的番茄新品系，大荚型油菜新类型，果大一倍的白莲种子和百合鳞。空间特殊条件能够引起植物种子后代众多的变异，是农作物诱变育种的一个新的途径。

Since 1987, about fifty species, three hundred varieties of crops have been sent in recoverable satellites or high altitude balloon(HAB). The selected lines include a high yeild,disease resist,and hybrid vigorous rice line, a recovered line of Japonica rice restoring sterility of Indica rice,a new green pepper strain which grows fruits over 500 g,a disease resist,high quality tomato line,a big pod rape line,a big fruit white lotus line and a big bulb lily.The special conditions in the outer space can induce a variety of mutations in the plants and their progeny, which provides a new way for the plant breeding.
