ABSTRACT

Antheraea mylitta, a wild sericigenous insect is a species widely distributed from West Bengal in the in the East to Karnataka in the South with its natural inhabitation in the forest area of Bihar, Orissa, Madhya Pradesh, Maharashtra and Andhra Pradesh and Telangana. It is a polyphagous insect feeding on a number of food plants primarily on Terminalia arjuna and T. tomentosa and a host of secondary food plants. The wide range of distribution of the species has encountered diverse geographic and climatic variations of the distinct areas, leading to marked differences in not only phenotypical and physiological traits but also in the commercial and technological aspects. Antheraea mylitta Drury (Andhra local ecorace), is an exclusive race of State of Telangana and Andhra Pradesh. The present study is on The improved varieties of these silkworms can be evolved by hybridization between Andhra local and Daba TV ecoraces by backcross method, breeding of tasar ecoraces is aimed at the improvement of to be bestowed with superior characters i.e., survivability and fecundity of Daba TV and also as one of the probable strategies for enhancing the productivity and quality of tasar raw silk by breeding method to improve the traits in the upcoming generation by selective parental selection. Keywords: Antheraea mylitta Drury, Tasar silkworm, Ecoraces, Breeding, Backcross, phenotypical and physiological traits
