摘要
作者研究了7个微卫星标记在2个南疆绒山羊群体中的遗传多样性,并用SAS中GLM过程分析了抓绒量、抓绒体重、绒纤维平均直径、绒纤维直径变异系数、净绒率和绒丛长度6个经济性状的标记效应及群效应。结果表明,在南疆绒山羊群体中,等位基因数为4-8个,多态信息含量为0.3186-0.7930,杂合度为0.3344-0.8175。抓绒体重和净绒率存在群效应,BMS 2782位点的A、CI、三个基因型和IDVGA 64位点的B基因型为绒丛长度的优势基因型,LSCV 13位点的B基因型为产绒量的优势基因型。
The genetic diversity of five microsatellites were studied in 317 individuals in tow Nanjiang cashmere goat populations.A GLM procedure was used to analyze the effects of these 5 markers and 2 herds on 6 economic traits（cashmere weight,body weight,average diameter of the cashmere fiber,coefficient of the fiber diameter variation,net cashmere rate,thickness of the cashmere sheet）.Results indicated： the number of alleles for the five microsatellites,PIC（polymorphism information content） and heterozygosity were 4 to 8, 0. 3186 to 0. 7930,and 0. 3344 to 0. 8175,respectively;the herd has a significant impact on bodyweight and net cashmere rate. A, C and I at BMS 2782, B at IDVGA 64 were favorable genotypes for cashmere sheet thickness. B at LSCV 13 was favorable genotype for cashmere weight.
