【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。更多还原

【Abstract】 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.更多还原
