Nine microsatellite loci selected according to the genetic map of male goat and related reports were studied to reveal genetic diversity of the population including 50 Longdong cashmere goats,a special chinese genetic resource,by 8% non-denatured polyacrylamide gel electrophoresis detecting the product of PCR for MAS.The relating effects between markers and economic traits were analyzed in a generalized linear mode.The results indicated that the total number of alleles were 90,average allele numbers were 10.allele numbers of LSCV24 were 14 while allele numbers of DB6 were 6.The average PIC values and the average genetic heterozygosity were(0.84±0.03) and(0.86±0.03)in Longdong Cashmere goats,respectively.Nine microsatellite loci had significant effect on some economic traits of Longdong Cashmere goats,meanwhile,we also discovered that favorable genotype and some alleles above loci had positive effect and negative effect on interrelated economic traits.
