摘要: 目的 利用团体标准T/CALAS 21—2017推荐的方法对不同时期封闭群Wistar大鼠的遗传质量进行分析,同时进行团体标准T/CALAS 21—2017的适用性评价。 方法 2015年、2019年选测的Wistar大鼠分别命名为A组和B组。按团体标准T/CALAS 21—2017要求,使用25对微卫星引物获取两组封闭群Wistar大鼠的遗传参数进行质量分析,利用多态性信息含量(polymorphism information content,PIC)分析位点多态性。 结果 A组和B组大鼠中分别检测到100个和69个等位基因。两群体平均杂合度分别为0.574和0.447,平均PIC分别为0.541和0.393。 结论 团体标准T/CALAS 21—2017在封闭群大鼠遗传质量分析中具有良好的适用性,A组Wistar大鼠的遗传多样性优于B组。

Abstract: Objective To analyze the genetic quality of an outbred stock of Wistar rats in different periods by T/CALAS 21—2017 method, and to evaluate the applicability of the association standard. Methods Wistar rats selected from the same outbred stock in 2015 and 2019 were named as group A and group B, respectively. Twenty-five pairs of microsatellite primers were used to get genetic parameters for quality analysis of the outbred stock Wistar rats according to the association standard T/CALAS 21—2017. Polymorphism information content (PIC) was used to analyze the polymorphism of the loci. Results One hundred alleles in group A and 69 alleles in group B were obtained. The average heterozygosity of the two groups was 0.574 and 0.447, while the average PIC was 0.541 and 0.393, respectively. Conclusion The association standard T/CALAS 21—2017 has good applicability in the genetic quality analysis of outbred stock rats, and the genetic diversity of group A is better than that of group B.
