Abstract
The tropical tasar silkworm, Antheraea mylitta D. is a semi-domesticated, trivoltine, wild, sericigenous insect (Lepidoptera: Saturniidae), existing in the form of more than forty ecoraces /ecotypes based on geographical and basically feeding on Terminalia sp. The improved varieties of these silkworms can be evolved by hybridization between Andhra local and Daba TV ecoraces by backcross method, to improve the traits in the upcoming generation by selective parental selection. The present studies of genetic relations is based on phylogeny of Tasar ecoraces using SSR markers, which further provides molecular evidence of the fact that climatic factors, the changes at DNA level and its wide range of distribution in varied geographic conditions would lead to genetic divergence, ultimately leading to the formation of new ecorace.
