Abstract:
The nature of performance of any silkworm hybrid depends on various aspects but most importantly on the climatic conditions prevailing in a particular area. Thus, the need of identification and evaluation of region and season specific hybrids attracts the attention of silkworm researchers. The present investigation was undertaken to assess the performance of indigenous silkworm hybrids on various important economic traits for their evaluation as potential bivoltine hybrids suitable for subtropical conditions of Jammu Division. Among twelve selected hybrids, FC1×FC2, PO3×ND5, U-3×U-1, U-4×U-6, JD6× U6, ND3x NSP have been recognized as superior bivoltine hybrids in term of various commercial parameters. Additionally, the silkworm hybrid FC1×FC2 exhibited maximum total filament length of 1029 meters followed by PO3×ND5 and U-4×U-6 (969, 961 and 933 mts resp.) and filament size FC1×FC2 followed by U-3×U-1 (2.50 and 2.55) which proves the economic viability of these hybrids. Therefore, the current findings will provide an insight to the future aspects of silkworm breeding for development of region and season specific hybrids with improved qualitative and quantitative characters.
