摘　　要：遗传多样性能有效反映大黄鱼的遗传变异,是评判其进化和适应能力的重要标志。目前有关大黄鱼种质遗传多样性的研究已取得丰富的成果;形态学、同工酶和DNA分子等相关研究的结果显示:大黄鱼遗传多样性较低,各群体间的遗传差异较小。综述了有关大黄鱼遗传多样性的研究进展,并就大黄鱼种群的划分、种质资源的管理和恢复问题作了探讨,以期为大黄鱼遗传育种和种质保护工作提供参考。Genetic diversity can reveal genetic variation of the large yellow croaker（Larimichthys crocea）,and is an important indicator to evaluate the evolution and adaptation ability of the species.Up to date,related studies（such as morphology,isoenzyme and DNA molecular markers etc.） on the genetic diversity of the large yellow croaker indicated a relatively lower genetic diversity at the population level and there were no obvious genetic differentiation among populations.The aim of this review is to present an update of the knowledge generated so far on different aspects of the genetic diversity,clas-sification of populations and germplasm management of large yellow croaker.This information will expand our knowledge and may contribute to genetic breeding and conservation of the large yellow croaker.
