ABSTRACT
The effective management of endangered animal genetic resources is one of the most important concerns of modern breeding. Evaluation of genetic diversity and relationship of local breeds is an important factor towards the identification of unique and valuable genetic resources. This study aimed to analyze the genetic diversity and population structure of six Korean native chicken breeds (n = 300), which were compared with three imported breeds in Korea (n = 150). For the analysis of genetic diversity, 30 microsatellite markers from FAO/ISAG recommended diversity panel or previously reported microsatellite markers were used. The number of alleles ranged from 2 to 15 per locus, with a mean of 8.13. The average observed heterozygosity within native breeds varied between 0.46 and 0.59. The overall heterozygote deficiency (F IT) in native chicken was 0.234±0.025. Over 30.7% of F IT was contributed by within-population deficiency (F IS). Bayesian clustering analysis, using the STRUCTURE software suggested 9 clusters. This study may provide the background for future studies to identify the genetic uniqueness of the Korean native chicken breeds.

UPGMA dendrogram of genetic among nine chicken breeds based on DA genetic distances (Nei et al., 1983) estimated with 30 microsatellites. Numbers on the nodes are bootstrap values of 1000 replications. KR, Korean Reddish Brown; KY, Korean Yellowish Brown; KB, Korean Black; KG, Korean Grayish Brown; KW, Korean White; RI, Rhode Island Red; KO, Korean Ogye; CN, Cornish; WL, White Leghorn.

f1-ajas-27-10-1399: UPGMA dendrogram of genetic among nine chicken breeds based on DA genetic distances (Nei et al., 1983) estimated with 30 microsatellites. Numbers on the nodes are bootstrap values of 1000 replications. KR, Korean Reddish Brown; KY, Korean Yellowish Brown; KB, Korean Black; KG, Korean Grayish Brown; KW, Korean White; RI, Rhode Island Red; KO, Korean Ogye; CN, Cornish; WL, White Leghorn.

Mentions: The Nei’s DA genetic distance is basically a correlation among the allele frequencies between breeds. Table 4 shows DA genetic distance between each pair for all nine chicken breeds, based on 30 microsatellite loci genotypes. The genetic distance ranges from 0.161 (KR and KY) to 0.450 (WL and RI). The genetic distance among five Korean native breeds (KR, KY, KG, KB, and KW) were also found to be quite low (0.161 to 0.243). Figure 1 shows a phylogenetic tree of nine chicken breeds that was constructed from DA genetic distances by using the unweighted pair group method with average linkages (UPGMA) dendrogram. Five Korean native breeds clustered together under one group, and formed a close group with RI. The WL culminates on a different node forming the out-group.
