Abstract

Stability studies conducted with the mulberry silkworm, Bombyx mori L. revealed that the double hybrid, [(CSR6 x CSR26) x (CSR2 xCSR27)] performed better for cocoon length, cocoon breadth, larval weight, cocoon weight, shell weight, shell ratio and survival percentage compared to the bivoltine hybrid, CSR2 x CSR4 when reared at two different environmental conditions viz., room temperature and humidity (25±10ºC and 65±5 % RH) and higher temperature and humidity conditions (34±10ºC temperature and 85±5 % RH)
