摘　　要：应用简单随机抽样法,在青海省德令哈抽取柴达木绒山羊57只,利用聚丙烯酰胺凝胶电泳技术测定9个血液蛋白质(酶)位点(α2,Alb,Hb,Alp,PA-3,EsD,Amy,Tf,LAP),并对毛色及形态特征进行了遗传检测,结果表明,9个血液蛋白质(酶)位点中有6个位点表现出多型性,均由2个等位基因控制,位点平均杂合度为0.2773,9个外形特征中5个有多型性,其平均异质度为0.4610,毛色趋于纯白。利用群体遗传贴近度分析方法,剖析了柴达木绒山羊与其亲本群的相似程度,即外形特征上,柴达木绒山羊与辽宁绒山羊相似,而在血液蛋白质(酶)位点上柴达木绒山羊与柴达木山羊相似;在总体特征上,柴达木绒山羊与柴达木山羊、辽宁绒山羊的遗传贴近度分别为0.8257、0.8662。Genetic structure and character of 57 Chaidamu cashmere goats are studied through simple random sampling,and genetic structure are estimated with PAGE of 9 blood protein（α2,Alb,Hb,Alp,PA-3,EsD,Amy,Tf,LAP）,and phylogeny status are investigated.The result indicated that： there was polymorphous blood albumen in 6 loci and the average loci heterozygosity was 0.2773;the average phenotypic heterogeneity degree of coat color and appearance character are 0.4610;using the analyze of the degree of genetic similarity,the relationship between Chaidamu cashmere goat populations and it＇s parent groups;the coefficient of genetic differentiation between Chaidamu cashmere goats and Liaoning cashmere goats is less than that between Chaidamu cashmere goats and Chaidamu goats on appearance character; the coefficient of genetic differentiation between Chaidamu cashmere goats and Chaidamu goats is less than that between Chaidamu cashmere goats and Liaoning cashmere goats on blood protein marker^the degree of genetic similarity of between Chaidamu cashmere goats and Chaidamu goats, between Chaidamu cashmere goats and Liaoning cashmere goats are 0. 8257 and 0. 8662, respectively.
