The production of tasar silk, a valuable natural fiber obtained from the silkworms of the Antheraea genus, holds significant socio-economic importance in the state of Chhattisgarh, India. In this region, two prominent ecoraces of tasar cocoons, namely Daba and Raily, are extensively cultivated for silk production. However, variations in cocoon characteristics and reeling performance between these ecoraces have been observed, leading to differences in silk yield and quality. This research aims to comprehensively investigate and compare the quality characteristics and reeling performance of Daba and Raily tasar cocoons to understand their suitability for silk production in the Chhattisgarh region
