| 摘 要： | Thirty-five SSR markers were used to construct 96 silkworm races fingerprint. All the SSR markers were polymorphic and unambiguously separated silkworm strains from each other. A total of 467 alleles were detected with a mean value of 13.34 alleles/locus （range 3-28）. The mean polymorphism index content （PIC） was 0.71 （range 0.299-0.919）. UPGMA cluster analysis of Nei＇s genetic distance grouped silkworm strains on the basis of their origin. The results indicated that SSR markers are efficient tools for fingerprinting cultivars and conducting genetic diversity studies in the silkworm.
