Genetic variation in ecoraces of tropical tasar silkworm, Antheraea mylitta using SSR markers

Wild silk insect of Simlipal biosphere and its molecular genetic diversity for conservation

Designated silkworms (Antheraea mylitta D.) are found in the Smilipal Biosphere Reserve (SBR) and consist of four ecological groups. This study examined the genetics of eight ethnic groups from four ecological groups (Modal, Nalia, Bogai and Jata) using RAPD and ISSR markers. The RAPD primer produced 127 bands, of which 41 out of 116 polymorphic regions had a PIC value above 0.45. ISSR markers assigned PIC data values to 57 of 127 polymorphic sites. Cluster analysis revealed genetic differences between ecological populations, with markers separating ecological populations into groups. Low testicles and high genetic diversity indicate that these individuals are at different levels. If adequate protection is not provided, the risk of extinction of ecospecies designed in SBR increases. This study shows that the combined use of RAPD + ISSR markers can improve the results of the technology in identifying different diseases in situations where genomic information is limited.
