| 中文摘要: |
| 甘薯是一种重要的粮食作物，块根中具有高含量的淀粉和丰富的营养物质。在甘薯育种中，杂交育种为其主要育种途径，但因甘薯种内及种间存在较高程度杂交不亲和性，对甘薯育种亲本的选择及种质资源的利用造成了严重的限制。为了克服甘薯杂交不亲和性，国内外学者针对不亲和性机理及克服方法开展了大量研究，主要包括甘薯种内不孕群的划分、甘薯种内和种间杂交不亲和性生理及分子遗传机制的研究、甘薯杂交不亲和性克服试剂的筛选、体细胞杂交对甘薯种内及种间杂交不亲和性的克服等。主要从以上各方面对相关研究进展进行综述和讨论，以期为甘薯杂交不亲和性的克服及相关机理的研究提供参考。 |

| Sweetpotato is an important food crop, with high starch content and rich nutrients in tuberous root.
For sweetpotato breeding, cross breeding is the main breeding way. However, the characteristics of intraspecific and
interspecific cross-incompatibility are the serious obstacle for sweetpotato crossbreeding and germplasm resources
utilization. In order to overcome sweetpotato cross-incompatibility, lots of work had been carried out and focuses
on mechanism study and overcoming method, including intraspecific cross-incompatibility group division, crossincompatibility
physiology and molecular mechanism research, cross-incompatibility overcoming reagents selection
and application, somatic hybridization applying in the cross-incompatibility overcoming and so on. Here, we reviewed
the detailed research progress of these works, so as to provide a reference for sweetpotato cross-incompatibility
overcoming and further research in related mechanism. |
