چکیده

Silkworm (Bombyx mori) is an important economic insect which is used as experimental material for the evolution of economically important silkworm breeds. Breeds/strains thus evolved are maintained in germplasm stations for breeders and researchers to use. The Islamic Republic of Iran has valuable silkworm genetic resources which differ in cocoon shape. Fifty-four oval cocoon strains maintained by the Iran Silkworm Research Station (ISRC) were analyzed for the estimation of evaluation index to study their genetic divergence.
