摘要
利用微卫星技术对我国特有遗传资源150头辽宁新品系绒山羊的11个微卫星位点进行了研究,对其进行群体遗传学特性分析,并利用SAS程序下的GLM分析了体重、产绒量和绒细度3个经济性状与标记基因型的关系,结果表明:在 LSCV13位点,AA和BC型为体重性状的优势基因型,AB型为绒产量性状的优势基因型。在CSSM11位点,AD和BE型为绒产量性状的优势基因型,AA型为绒细度性状的优势基因型。在IDVGA64位点DE为体重性状的优势基因型,BD和 CC型为绒产量性状的优势基因型,BC和DE型为绒细度性状的优势基因型。在BMS2782位点,BB型为体重性状的优势基因型,BC和DE型为绒产量性状的优势基因型,CD型为绒细度性状的优势基因型。
The economic traits of Liaoning new breed of cashmere goats, a special Chinese genetic resource, were analyzed in 150 animals by typing 11 microsatellite loci. The association between three economic traits （body weight, cashmere yield and fineness） in this new breed of goats and the marker genotypes were analyzed. The results show that： AA and BC at LSCV13, DE at IDVGA64 and BB at BMS2782 were favorable genotypes for body weight. AB at LSCV13, AD and BE at CSSMll, BD and CC at IDVGA64, BC and DE at BMS2782 were favorable genotypes for cashmere yield. AA at CSSM11, BC and DE at IDVGA64, CD at BMS2782 were favorable genotypes for cashmere fineness.
