| 摘要: |
| 利用链霉素在普通小麦品系BAU92和BAU3338中分别诱导出雄性不育突变，遗传分析表明其不育性分别受隐性和显性细胞核基因控制。BAU92雄性不育突变体雄性器官败育彻底，遗传稳定；BAU3338雄性不育突变体雄性器官败育不彻底，自交有较低结实率。这些雄性不育材料可作为新的小麦雄性不育道传资源。链霉素诱变小麦雄性不育具有较好重视性，可作为创造小麦雄性不育的新途径。 |

| Abstract: |
| Both cytoplasmic and genic male sterility are useful for wheat genetics and breeding. Seven stable and complete male-sterile mutants in BAU92 and a new kind of in-complete male-sterile mutant with low seedset (less than 5%) of self pollination in BAU3338 have been obtained by the treatment of sreptomycih. Genetic analysis indicated that single recessive and single dominant genes were involved in the genetic control of the induced male sterile wheat mutants in BAU92 and BAU3338 respectivily. With high re-producibility, it was concluded that streptomycin induction could be an additional approacl1for creating novel male sterility in wheat. |
