Abstract:
The investigation was carried out at Department of Sericulture, in University of Mysore, Manasagangotri during 2019. The work was undertaken to study on influence of supplementation of Thiamine with mulberry leaf on selected bivoltine hybrids FC₁ and FC₂. Supplementation is a modern technique in advanced sericulture research and development industry to enhance the cocoon yield through supplementation of amino acid on mulberry leaf. Amino acids play an important role in the growth and development of silkworm, Bombyx mori. The selected bivoltine hybrids FC₂ and FC₁ performed better in respect of economic traits such as larval weight (3.73 and 3.71 g), cocoon weight (1.62 and 1.48 g), shell weight (0.30 and 0.29 g), shell ratio (23.54 and 21.10 %), filament length (1678 and 1513 m), filament weight (0.23 and 0.22g), denier (1.17 and 1.23) and renditta (5.12 and 5.52 kg) in 600 ppm of Thiamine supplementation when compared to other concentrations and control, Further FC₂ showed better reading compared to FC₁.
