EVALUATION OF DIFFERENT SILKWORM HYBRIDS IN JAMMU REGION.

The agro climatic conditions of Jammu and Kashmir State are most ideal for bivoltine silkworm rearing. However, quality cocoon production at commercial level has suffered mostly because of inadequate quality of leaves, due to lack of infrastructure facilities for silkworm rearing at farmers level, improper diffusion of technologies required for silkworm rearing at farmers level. Besides, these factors the silkworm race reared by farmers also affects the silkworm rearing. In this direction, the present study was undertaken and four different silkworm hybrids, namely; I) SH6 x NB4D2, II) Double Hybrid (CSR6 x CSR26) x (CSR2 x CSR27), III) FC1 (CSR6 x CSR26) IV) FC2 (CSR2 x CSR27) were selected for rearing in spring season during the year 2014. These four hybrids were reared at Regional Sericulture Research Station (RSRS), Miran Sahib, Jammu, in order to evaluate the performance of different silkworm hybrids in Jammu region. Results obtained during rearing of these hybrids showed that overall performance of CSR Double hybrid (CSR6 x CSR26) x (CSR2 x CSR27) was better over the other three silkworm hybrids.
