Abstract: For selection and breeding of multiple objective traits in production practice, the economic traits of Liaoning new line cashmere goat were analyzed by 125 microsatellite loci on the whole 29 chromosomes. The association among three economic traits (body weight, cashmere yield and cashmere fineness) and the marker genotypes was analyzed. The results showed that there were 111 microsatellite loci showing high polymorphism (PIC>0.5) and 4 microsatellite loci showing intermediate polymorphism(0.25<PIC<0.5),and 10 loci include BM1312 showing monomorphism. Effects of 115 polymorphic microsatellite loci on economic traits were also analyzed. The genotypes which favorably affect the three economic traits(body weight, cashmere yield and cashmere fineness) were found. Especially, DE at MoM064 (112117 bp) was favorable genotype for cashmere fineness and cashmere yield.This research provides an experimental basis for selection and breeding of multiple objective traits in production practice.
