| 摘 要： | 应用陕西４个黄牛群体的６个血液蛋白位点、８个毛色位点及７项形态特征共２１类遗传标记特征的分布频率进行综合模糊聚类分析，结果表明：在取ＭＲ＾４＝０．９７４时，将陕西４个黄牛群体划分为南北２种类型。确认秦岭山脉是陕西不同类型黄牛群体在地理上的分界线。亦确认多层次综合聚类是目前黄牛品种类划分最适宜之方法。

| Abstract: | The mufti-level synthetic fuzzy cluster analysis was carried out by applying the frequencies of 21 genetic mark characters (i.e.6 blood protein loci,8 coat colour loci and 7 appearance characters) in 4 yellow cattle populations of Shaanxi.The results indicated that 4 yellow cattle populations of Shaanxi could be divided into the North and South types at MR4=0.974;and it is affirmed that Qinling Mountains is the demarcation line of the different types and that mufti level synthetic cluster was a most suitable method to yellow cattle breed classification at present. |
