构建核心种质是植物遗传资源的研究热点和重点之一,对种质资源的鉴定、保存、利用与交流具有重要意义。本文简要介绍了植物遗传资源核心种质的概念及其构建方法,综述了园艺作物核心种质构建的研究新进展,并对今后该领域的研究趋势进行了展望。提出了种质分组及取样策略是园艺作物核心种质构建方法研究的重点;应及时构建一批大宗园艺作物以及我国原产和特产园艺作物的核心种质;高度重视基于重测序技术快速、精准、高通量地挖掘园艺作物核心种质优异基因的研究以及要加强科研管理与协作,切实提高我国园艺作物核心种质研究成果的共享性等观点,为园艺作物种质资源的深入研究与高效利用提供理论依据和技术参考。
The construction of core collection is one of the hotspots and focuses of plant genetic resources. It is of great significance to identify, preserve, utilize and exchange germplasm resources. This paper briefly introduces the concept of core collection of plant genetic resources and its construction methods, reviews the new research progress in the construction of core collection of horticultural crops and prospects the future research trends in this area. It is put forward that the germplasm grouping and sampling strategy are the focus of the research on the method of constructing the core collection of horticultural crops. A batch of large horticultural crops should be constructed in time, as well as the core germplasm of the native and special horticultural crops in our country. , High-throughput mining of horticultural core gene collection of excellent gene research and to strengthen scientific research management and collaboration, and effectively improve the core research of horticultural crops in China share the same research results for the in-depth study of horticultural crop germplasm resources and efficient Use to provide theoretical basis and technical reference.
