Evaluation and Identification of Silkworm (Bombyx mori L) Genetic Resources Tolerant to Temperature and Humidity

The aim of the study is identification bivoltine breeds suitable for regional abiotic stress conditions to achieve successful cocoon production.
 Study Design: In this regard present has been taken up with ten accessions (4 oval and 6 dumbbell) linked thermo tolerance SSR markers evaluated under different agroclimatic namely, (a) high temperature low humidity; (b) moderate humidity (c) humidity.
 Place Duration Study: 2 years , where trials were conducted at CSR & TI, Berhampore (West Bengal), RSRS, Jammu (J&K) REC, Chitradurga (Karnataka).
 Methodology: shortlisted (oval showing hotspots collected reared locations data collection analysis rearing parameters viz. larval wt.(g), ERR/No., (survival) ERR/wt (kg), pupation rate (%), single weight (g), shell (g),shell ratio (%) along control CSR2 (oval) CSR4 (dumbbell).
 Results: Among accessions, performance BBI-0086 [KPG-A], BBI-0339[DD-2], BBE-0184[SMGS-2] BBI-0338[DD-1], BBI-0336[APS-8] found be stable in all respectively.
 Conclusion: elucidate impact associated over economic traits performances selected accessions. findings provide a platform future crop improvement through breeding program.
