Abstract: 35 SSR markers were used to construct 96 silkworm races fingerprints, including 47 European monovoltine races, 13 Japanese monovoltine races, 1 Japanese bivoltine races and 35 Chinese bivoltine races. All of 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 based on their origin. The results indicated that SSR markers are an efficient tool for fingerprinting cultivars and conducting genetic-diversity studies in the silkworm.
