Abstract

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 CSSM11, 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.

摘要

通过对11个微卫星基因座进行分型，对150只中国特有的辽宁新品系绒山羊的经济性状进行了分析。分析了该新品系山羊的三个经济性状（体重、产绒量和绒细度）与标记基因型之间的关联。结果表明：LSCV13基因座的AA和BC基因型、IDVGA64基因座的DE基因型以及BMS2782基因座的BB基因型是体重的有利基因型。LSCV13基因座的AB基因型、CSSM11基因座的AD和BE基因型、IDVGA64基因座的BD和CC基因型、BMS2782基因座的BC和DE基因型是产绒量的有利基因型。CSSM11基因座的AA基因型、IDVGA64基因座的BC和DE基因型、BMS2782基因座的CD基因型是绒细度的有利基因型。
