Genetic Diversity and Structure of Korean Pacific Oyster (Crassostrea gigas) for Determining Selective Breeding Groups

Year: 2025

Type: article

Abstract: This study investigated the genetic diversity and structure of thirteen wild populations of Crassostrea gigas in Korea. The purpose of this investigation was to provide foundational data for selecting reference populations to enhance genetic diversity. Overall, the genetic diversity of Korean C. gigas was relatively low. Analysis using AMOVA, genetic differentiation, and DAPC revealed a genetic structure that was consistent with one group. This study identified reference populations to be used for selective breeding to increase the genetic diversity of Korean C. gigas and provided essential data on genetic diversity and structure for future selective breeding efforts in C. gigas.
