摘　　要：辣椒种质资源是改良辣椒品种的物质条件,构建核心种质能够以最小数量最大限度保存种质资源遗传多样性,为挖掘辣椒优异基因奠定材料基础,对提高杂交种亲本的选配效率进而缩短育种进程具有重要意义。本文从辣椒种质资源收集、评价和遗传多样性分析等方面展开概述,总结了辣椒核心种质构建的研究进展,并提出辣椒核心种质构建存在的问题及展望,为辣椒种质资源的深入研究与高效利用提供理论依据及技术参考。Pepper germplasm resources are the material conditions for improving pepper varieties.The construction of core germplasm can preserve the genetic diversity of germplasm resources to the maximum extent with the minimum number,lay a material foundation for mining excellent genes in pepper,and have great significance for improving the efficiency of hybrid parent selection and shortening the breeding process.In this paper,the collection,evaluation and genetic diversity analysis of pepper germplasm resources were summarized,the research progress of pepper core germplasm construction was summarized,and the existing problems and prospects of pepper core germplasm construction were put forward,which provided theoretical basis and technical reference for in-depth research and efficient utilization of pepper germplasm resources.
