| 摘要: |
| 利用非1B/1R类型小麦K型不育系KTSP3314A和1B/1R类型小麦K型不育系K3314A，分别与10个普通小麦品种（系）259，3665，TB902，F107，J18，R205，L783，503，3380和78115杂交，测定和比较其恢复性、单倍体发生频率和主要农艺性状。结果表明，非1B/1R类型小麦K型不育系比1B/1R类型小麦K型不育系更易恢复；不育系本身不产生单倍体，其杂交种F1产生极少或不产生单倍体；农艺性状除了株高具有明显的优势外，其他均无不利的遗传效应。 |

| Abstract: |
| Wheat CMS lines of Ae.kotschyi cytoplasm of No 1B/1R type wheat and 1B/1R type wheat were crossed with 10 common wheat lines.The fertility-restoring feature of male-sterile line,haploid frequency and main agronomic characters were investigated.The result indicated that wheat CMS lines of Ae.kotschyi cytoplasm of No 1B/1R type wheat have better fertility-restoring feature and less haploid than wheat CMS lines of Ae.kotschyi cytoplasm of 1B/1R type wheat.There were better genetic effects on almost all agronomic characters exceopt for the plant height. |
| Key words: No 1B/1R type 1B/1R type Ae.kotschyi wheat CMS line restoring feature haploid frequency agronomic character genetic effect |
