| 利用单芒山羊草细胞质雄性不育系U401、U402、U8567、U513,粘果山羊草细胞质雄性不育系K401、K402、K8567、K513,及其同型保持系A401、A402、A8567、A513与10个普通小麦品系杂交,测定和比较其恢保关系和单倍体发生频率,结果表明,U型不育系与K型恢保关系基本一致,但也存在差异。U型不育系育性恢复较K型难,且更易受气候条件影响。U型不育系诱导单倍体频率较K型高。 |

| Abstract: |
| Ae.Uniaristata cytoplasm wheat male sterile lines U401,U402,U8567,U513,Ae.Kotschyi CMS lines K401,K402,K8567,K513 and their maintainer lines A401,A402,A8567,A513 were crossed with 10 common wheat lines.The restoration and maintaining relationship and haploid frequency were determined.The result indicated that the relationship of restoration and maintaining of wheat CMS lines of Ae.Uniaristata cytoplasm was almost identical to that of K type CMS lines,though some differences exist between them.The fertility of U type CMS lines was more difficult to be restored.The U type cytoplasm caused slightly higher haploid frequency than K type. |
