Central Sericultural Research and Training Institute, Mysore have evolved several highly productive bivoltine hybrids which can produce international grade raw silk. Among them CSR2×CSR4, CSR2×CSR5, CSR3×CSR6, CSR17×CSR16, CSR18×CSR19 and CSR12×CSR6 are being popularized in the field. There is a minimum difference in their economic characters but they appear to differ in survival. Though they are productive under high input management conditions, they are very susceptible to different diseases under normal rearing practices.
