摘　　要：番茄分子育种是运用分子辅助手段加快育种进程、提高育种效率的育种方式。遗传群体是研究番茄重要性状遗传特性、挖掘重要遗传位点的基础,用于图谱构建、QTL定位、基因克隆及分子标记开发,同时遗传群体也可以用于育种材料创建。在番茄分子育种中常用的遗传群体包括F_(2)、RIL(重组自交系)、NIL(近等基因系)和IL(渐渗系)等分离群体。本文主要综述了临时性遗传群体及永久性遗传群体的特点,阐述了这些遗传群体在图谱构建、基因定位及鉴定、种质资源创制方面的应用,为遗传群体在番茄分子育种的应用提供参考。Tomato molecular breeding is a breeding strategy that uses molecular assisted selection to accelerate the breeding process and improve breeding efficiency.Genetic population is the foundation for studying the genetic basis of important traits and mining important genetic loci in tomatoes.It is used for genetic map construction,QTL mapping,gene cloning,and molecular marker development.At the same time,genetic populations can also be used for the creation of breeding germplasm.The commonly used genetic populations in tomato molecular breeding include F_(2),RIL,NIL,IL and other populations.This review summarized the characteristics of temporary and permanent genetic populations,and introduced the applications of these genetic populations in map construction,gene localization and identification,and germplasm resource creation to provide reference for the application of genetic populations in tomato molecular breeding.
