Genetic Biodiversity of the Breeding Population of the Red and White Koi Carp

Abstract

Research on genetic biodiversity can essentially reveals the origin of species diversity, variation and evolution. The koi carp (Cyprinus carpio L) is well known for its vigorous body and gorgeous colour. However, there is still lack of knowledge for Koi carp genetic biodiversity. In this paper, the genetic biodivesity of 15 microsatellite loci in breeding population of red and white Koi carp was analyzed. Our results showed that 56 alleles were detected in the population by 15 microsatellite primers, and the number of allele at each locus ranged from 3 to 5, with an average of 3.73. The average observed heterozygosity was 0.6963 while the average expected heterozygosity was 0.6208. The average polymorphism information content (PIC) was 0.557. Out of 15 detected loci, 11 loci were in high polymorphism degree (PIC≥0.5), 4 locus was in medium polymorphism degree. The average Fis is -0.1251. The results indicated rich polymorphism information content and large genetic diversity in the population. This breeding population of the red and white Koi carp had a large selection potential and could be adopted as a base population for further selection.

“…This high level of genetic diversity could be the result of different source populations used to supplement the current pet shop populations (Mäkinen et al 2014). Other examples of genetic diversity analyses performed on commercially traded sh include studies on red and white koi carp (Cyprinus carpio L) (Shi et al 2020), guppies (Poecilia reticulata) (Bleakley et al 2008), and freshwater angel sh (Pterophyllum scalare) (Pandol et al 2021). High levels of genetic diversity were reported in breeding populations of red and white koi carp (Shi et al 2020).…”
