New Silkworm Varieties of Pakistan

ABSTRACT
Silk seed is the basic requirement for silk production.
This article describes the work of silkworm breeding in
Pakistan. Four new silkworm varieties were developed
from imported F1 hybrid silk seed by inbreeding and
selection to produce a F1 hybrid for commercial fearing
in Pakistan. 1,500 boxes of F1 hybrid disease free
silkworm seed was produced in 1988 and 2,100 boxes in
1989, for the first time in the country for distribution
amongst the farmer for rearing. During breeding and
selection of the bi-voltine races sex limited mutants
were also selected for further research.
