ABSTRACT
In India 90 % of the raw silk produced is from Multi x Bi hybrids namely PM x CSR2 and PM x FC2 which are popular and ruling hybrids in southern part of the country. It is very much essential to replace the existing popular hybrids with PM x FC2 (SL), as the new breed FC2 (SL) is gifted with the potentiality for high cocoon yield of 87.04kg/100dfls and returns of Rs.27,853 / 100 dfls. In addition, the comparative performance of Multi x Bi. hybrids revealed the superiority of PM x FC2 (SL) with higher cocoon yield than the popular hybrids and 42.3% of the farmers harvested more than 80 kg. coccons/100dfls, while, only 15.05 and 5.90 % farmers harvested above 80 kgs in PM x FC2 and PM x CSR2 respectively. The advantages of the new Multi x Bi hybrid PM x FC2 (SL) over the existing Multi x Bi hybrids are discussed.
Key words :
Cocoon yield, High yield potentiality, Multi x bi hybrid, PM x FC2(SL), Silkworm.
