| Abstract: | In this study,the microsatellite markers which are closely linked to the main performance traits of beef cattle were chosen,and the regulation of linear valuation were used to evaluate beef performance traits of Yanbian yellow cattle,and the association between the microsatellite DNA and the beef performance traits were analyzed by using general linear model(GLM).The association between microsatellite loci(ETH10 and IDVGA46) and beef performance traits were also analyzed in this study.The results were as follows:For microsatellite locus ETH10,allele 209 had a positive correlation with topline and shoulders;allele 213 had a positive correlation with pasterns,rump and fineness;however,allele 215 showed a negative correlation with topline and rump.For microsatellite locus IDVGA46,allele 249 had a positive correlation with topline,fore limbs and hind limbs from appearance evaluation,loin width from muscularity evaluation and skeleton and skin from fineness evaluation;however,allele 203 had a negative correlation with head,topline,loin width,skeleton and skin,and allele 245 had a negative correlation with loin width,too. |
