Studies on Genetic Diversity and Phylogenetic Relationships of Korean Native Chicken using the Microsatellite Marker

Identification of Genetic Association among Different Colors of Korean Native Chicken Breeds through the RAPD-PCR Method

“…The results obtained varied considerably from the results of conventional MS typing for the red and yellow-red lines (Choi et al, 2012). However, the results of genetic diversity analysis within the cluster were similar to the results obtained by Seo et al (2015). In our results, the genetic distance between the red and yellow-red chicken lines was 0.62, indicating close proximity, but varied considerably from the black line KCO.…”

Genetic Diversity and Relationship of Ogye Population in Korea Using 25 Microsatellite Markers

“…현재까지 오계를 포함하여 우리나라의 재래닭 및 외래토착 종을 대상으로 MS 마커를 이용한 연구가 다수 보고되어 왔 으며, 오계 집단은 재래닭 및 외래토착종 집단과는 다른 하 나의 순수한 집단으로 뚜렷하게 구분되는 것으로 나타났다 (Lee et al, 2010;Suh et al, 2014;Seo et al, 2015 (Kong et al, 2006;Seo et al, 2013;Suh et al, 2014)에서도 높은 다형성을 나타내고 있는 것으로 보고되었다.…”

Genetic diversity and relationship of Korean chicken breeds using 12 microsatellite markers

“…Previously, 27 Microsatellite markers were investigated for the discrimination of KNC and commercial KNC (Seo et al, 2015;Seo et al, 2017;Choi et al, 2019). From these results, a total of 12 MS markers were initially selected, which have high expected heterozygosity (H Exp ) and polymorphic information content (PIC) values (Supplementary Table 1).…”

Chicken is one of the major livestock, especially for supplying proteins to human and the Korean native chicken (KNC) has been documented since approximately 2,000 years ago (Seo et al, 2013;Seo et al, 2015). But, due to their poor commercial performance, Korean native chicken breeds almost became extinct and the breeds that existed before the Korean War (1950)(1951)(1952)(1953), are almost all extinct (Seo et al, 2013;Choi et al, 2015). After the Korean War, commercial native chicken companies maintained various independent breeds while continuing production and market distribution (Seo et al, 2018).

“…The private native chicken breeding-stock company (Hanhyup) is responsible for more than 80% of the native chicken distribution in Korea and has maintained purebred chicken breeds (Hanhyup breeds) for commercial use for the past 60 years (Seo et al, 2018;Choi et al, 2019). Hanhyup breeds produced by mating the KNC and economically superior and naturalized breeds (Seo et al, 2017). A number of Korean chicken breeds were registered in Domestic Animal Diversity Information System (DAD-IS, http://dad.fao.org/) of the Food and Agriculture Organization (FAO).…”
