摘　　要：为探索空间条件对高粱干种子的诱变作用,对恢复系R111纯系种子经返回式卫星搭载处理后,筛选出了稳定特异矮秆突变体。本研究考察了矮秆突变体的株高、叶片、育性、花器和品质的变异规律,为高粱空间育种提供了依据。并经多代回交转育选出一批新的不育系和恢复系,应用于育种实践。Sorghum R-line R111 was carried by returnable satellite to investigate space induction. Dwarf type variants were selected. Variation of plant height, leaf,fertility ,flower and seed quality were observed. By using the dwarf type variants some R-lines and A-lines were developed and were applied in the breeding program.
