A study on conservation value evaluation of native black goat using Microsatellite (MS) marker information

Abstract

This research was conducted to present the possibility of utilization as basic data and future genetic resources for planning for breeding and breeding direction planning for the preservation of the Gyeongsang National University (GNU) line through genetic diversity, genetic structure and character analysis of GNU line black goats, by using Microsatellite (MS) marker. A total of 247 Korean native black goats of four lines were used (Dang-jin; DJ : 68, Jang-su; JS : 80, Tong-yeong; TY : 71, GNU : 30), and a basic statistical analysis confirmed values suitable for the study. In addition, as a result of FIS analysis, it is thought that line differentiation is occurring in the case of the GNU line because it is farther away from 0 (-0.110), which is the standard of Hardy-Weinberg equilibrium, in a negative direction than other goat lines. As a result of structural analysis of 4 lines including the GNU line, it was confirmed that the genetic structure of each line was different, and it is thought that an independent evolutionary process occurred due to differences in regional and geographical environments or characteristics. The difference in this genetic structure is that there is no genetic mixing, so it is judged that each line is independently conserved. Therefore, in this study, it is judged that the GNU line is valuable as a future genetic resource and can be used as basic data for maintenance and conservation through planned breeding considering inbreeding rate.
