Rearing Performance of Mulberry Silkworm (PM x CSR2) as Influenced by Different Mulberry Varieties Grown under UAS Seri Suvarna Technology with Protective Irrigation

摘要

Seven popular mulberry varieties viz., VI, S36, S34, S30, SI3, MR2 and RFS175 grown under UAS Seri Suvarna Technology with protective irrigation were evaluated for better performance through silworm bio-assay studies. Significantly higher third, fourth and fifth instar larval weight (0.118g, 0.62g and 3.89g), effective rate of rearing (98.30 %), cocoon weight (1.897g), pupal weight (1.559g), shell weight (0.337g), shell ratio (17.75%), silk productivity (4.67cg/ day) and cocoon filament length (875.92m) with significantly minimum fourth and fifth instar larval durations (4.12 and 7.21days), filament denier (2.01) and larval mortality (0.17%) were observed when PMxCSR2) larvae were fed on VI mulberry leaves.
