| 中文摘要: |
| 矮败小麦是显性核不育基因(Ms2)和显性矮秆基因(Rht-D1c)紧密连锁的具有表型遗传标记的特异种质,是理想的群体改良和相关遗传研究的重要工具。利用矮败小麦育种技术,结合单倍体育种和分子标记辅助选择等手段,可快速培育具有目标性状的导入系,实现多个目标基因在优良遗传背景下的聚合和定向构建轮回选择群体,加快小麦重要性状的改良速度,对选育有突破性状的新品种及创制遗传背景丰富的优良育种材料有重要价值。 |
| 英文摘要: |
| Dwarf male-sterile wheat is a specific germplasm with phenotypic markers closely linked to dominant sterile gene (Ms2) and dominant dwarf gene (Rht-D1c), which is an ideal tool for population improvement and related genetic research. By using the breeding technology of dwarf male-sterile wheat and combining with haploid breeding and molecular marker-assisted selection, we can quickly cultivate the introducing lines with target traits. The aggregation of multiple target genes can be realized under the background of excellent heredism. The recurrent selection populations were orientingly constructed to speed up the improvement of important wheat traits. It is of great value for breeding new varieties with breakthrough characters and creating excellent breeding materials with rich genetic background. |
