摘　　要：运用基因组重测序技术,对来自中国16个省(市)的板栗资源以及欧洲栗和日本栗共180份栗属种质资源展开遗传特性分析,结果成功鉴定出遗传变异位点48374108个。根据变异位点分析,180份板栗品种可划分为八大类群,不同类群间存在基因渗透现象,中国栗、欧洲栗、日本栗在进化历程中的群体动态变化明显不同,分析出北京到山东板栗群体的基因流。研究存在样本数量分布不均和分析维度有限的局限,未来需扩大样本范围并结合多组学深入研究。In this study,genome resequencing technology was employed to conduct an analysis of the genetic characteristics of a total of 180 Castanea germplasms,which included Chinese chestnut(Castanea mollissima)cultivars from 16 provinces in China,as well as European chestnut(Castanea sativa)and Japanese chestnut(Castanea crenata).As a result,48374108 genetic variation sites were successfully identified.According to the analysis of these variation sites,the 180 cultivars could be classified into eight major groups.There was a phenomenon of gene introgression among different groups.The population dynamic changes of Chinese chestnut,European chestnut,and Japanese chestnut during the evolutionary process were significantly different.The study also discovered the gene flow of the Chinese chestnut populations from Beijing to Shandong.However,the study has limitations such as uneven distribution of the sample size and limited analysis dimensions.In the future,it is necessary to expand the sample scope and conduct in-depth research by integrating multi-omics approaches.
