| 摘 要： | 应用中心产区系统随机整群抽样方法,以2个系统、5个群体(n=154)的6个血液蛋白位点、8个毛色位点和6项外形特征,对西镇牛进行了遗传检测。结果表明,应用此种方法估测的群体基因频率和表型频率可靠性和精确度均较高。根据西镇牛的遗传检测结果和形成因素,初步推断西镇牛含有我国南方黄牛与中原黄牛的血统,属一个典型的中间类型,亦是我国山区黄牛品种资源中一个宝贵的基因库。

| Abstract: | The genetic investigation was carried out on herds ( n = 154) from 2 system of Xizhen Yellow Cattle for 6 polymorphic blood protein and 8 coat colour locus and for 6 characters refelecting their exterior features by the stratified ran'dom cluster sampling in central area of distribution. The results obtained show that the precision and reliability of estimate drived by using this method for genetic and phenotype frequencies wete much higher than those from others. According to genetic investigation and phylogency of breed, it was infered preliminarily that Xizhen Yellow Cajtle is a medium-typa one between the South China Cattle and the Central China Cattle, lineage of which is contained by descents of both from south and central. As a result of these studies it was established that Xizhen Yellow Cattle is a valuable gene pool of the cattle genetic resource of the Mountain regions in China. |
