The silkworm, Bombyx mori is a beneficial insect of great economic importance in China for its silk production. In this study, we obtained 11 cleaved amplified polymorphic sequence (CAPS) markers and one PCR polymorphism marker from the genes of the silkworm, B. mori. A backcross progeny analysis showed that all these molecular markers were segregated in a Mendelian fashion and that polymorphisms were co-dominant. These markers were used to investigate the genetic diversity among 29 strains of B. mori from China, Japan and Europe. Cluster analysis, based on the genetic similarities calculated from CAPS data, grouped these strains roughly according to their geographical origin. One group contained silkworm strains from Europe and some of the Japanese strains were interspersed into the Chinese groups, whereas other Japanese strains clustered together.
