This study examines the relative differences in rearing performances as well as the effects of zonal differences on the productivity and quality of tasar cocoons of three mutant strains of the tasar silk worm, A. mylitta D. The findings show that the three mutant Tasar Silk Worm strains differ in their ability to nurture their young. Daba–blue has been proven to outperform Daba–yellow and Daba–almond in terms of rearing performance. Furthermore, zonal differences have an impact on the relative production and quality of tasar cocoons produced by mutant Antheraea mylitta D strains. The findings clearly reveal that the productivity and quality of tasar cocoons in the Jharkhand and Madhya Pradesh zones are far superior to those in the Orissa, West Bengal, and Bihar zones of the tasar producing states. Daba–blue has been found to outperform Daba–yellow and Daba–almond in terms of productivity and tasar cocoon quality. Because of the changes in their physio–genetic makeup, the results appear to be the result of genetic variability among the three mutant strains of A. mylitta D. The results show that, notwithstanding their differences, all three mutant strains of A. mylitta D. have established dominance over the control (Daba–green) in terms of breeding activity. As a result, the emergence of three unique mutant strains of tropical tasar silkworm is beneficial to tasar culture in general.

This Research Article is an effort to study the relative variations in respect of rearing performances and to study the impacts of zonal differences on the productivity and qualities of tasar cocoons of three mutant strains viz; Daba–blue, Daba–yellow and Daba–almond of tasar silk worm, A. mylitta D. Results obtained are indicative of the fact that the three mutant strains of Tasar Silk Worm differ among themselves in respect of their rearing performances. The performances of Daba–blue in respect of rearing performances have been found evidently better than the Daba–yellow and Daba–almond. Further, zonal differences influence the relative performances of mutant strains of Antheraea mylitta D in respect of productivity and quality of tasar cocoons. The results have clearly shown that the productivity and quality of tasar cocoons of Jharkhand and Madhya Pradesh zones are relatively better and superior to Orissa, West Bengal and Bihar Zones of tasar producing states. The performances of Daba–blue in respect of productivity and qualities of tasar cocoons have been found evidently better than the Daba–yellow and Daba–almond. The results obtained appear to be the outcome of genetic variability among the three mutant strains of A. mylitta D. on account of relative differences in their physio–genetic makeup. Results obtained are indicative of the fact all the three mutant strains of A. mylitta D. in spite of relative differences have registered their supremacy over the control (Daba–green) on account of desired beneficial mutation in relation to their breeding activities. Thus the evolution of three distinct mutant strains of tropical tasar silkworm is in the larger interest of tasar culture.
