| 摘 要： | 采用8个微卫星座位对福建省5个地方猪种(槐猪、官庄花猪、莆田黑猪、闽北花猪、武夷黑猪)的遗传结构进行了分析,计算了遗传杂合度、有效等位基因数、多态信息含量、Nei氏标准遗传距离。结果表明:8个位点均为高度多态位点;5个猪种群体内的遗传多样性比较高,8个微卫星位点平均杂合度介于0.7006～0.7760之间;多态信息含量在0.6917～0.7609之间;槐猪与武夷黑猪的遗传距离最小0.5531,官庄花猪与闽北花猪的遗传距离最大0.8618。

| Abstract: | Eight microsatellite DNA markers were used to study the genetic diversity of five indigenous pig breeds(Huai pig;Guanzhuang pig;Putian pig;Minbei pig;Wuyi pig).Heterozygosity,effective number of alleles,polymorphism information content(PIC)and Nei's standard genetic distance were counted. The results were showed as follow:8 microsatellite loci were medium or high polymorphism;The genetic diversity in five populations was higher;and the average genetic heterozygosity was between 0.7006 and 0.7760;the average polymorphism information content was between 0.6917 and 0.7609.The genetic distance between Putian pig and Minbei pig was the nearest(0.5531),while the genetic distance between Guanzhuang pig and Minbei pig was the furthest(0.8618). |
