Action Plan - Central Silk Board

Decisions:
The institute should examine the requirement of HP, UK, UP and J&K and suggest
the silkworm hybrids and mulberry varieties suited for those states.
A program on stabilization of Autumn Crop should be worked out in consultation
with the Director (Tech).
Wastage of resources through duplication work should be avoided. To ensure this,
they should undertake a thorough literature survey besides interacting with the
other Laboratories and universities working on sericulture in the region.
Request SKUAST, Mirgand to provide parental stock of the authorized silkworm
hybrid SKUAST-1 x SKUAST6 for conducting large scale trials / commercial use.
Conduct continuous training program for all the DoS staff besides conducting pre-
and post-training assessment of knowledge level at regular intervals.

• 59 new mulberry accessions were inducted into the germplasm bank raising the
number of accessions to 1239.
• Performance of 120 mulberry accessions was studied under rainfed conditions.
• 24 mulberry accessions were screened for salinity and alkalinity tolerance.
• 338 mulberry accessions were cryopreserved in National Cryogene Bank, NBPGR,
New Delhi.
• 73 multivoltine and 350 bivoltine silkworm accessions were characterized,
evaluated and conserved.
• 15 MV and 21 BV silkworm accession were identified as hardy races based on
esterase and alkaline protease enzyme inhibitor kinetics.
Decisions:
CSGRC, Hosur should prepare a road map with a clear vision for the
activities that are envisaged to be taken up in the annual plan.
Director (Tech) should take exclusively a meeting on Germplasm
maintenance and utilization.
Copies of the research papers published have to be circulated amongst all
the concerned CSB research Institutes and the abstracts placed in the
Institute’s web site and vice versa and update the databank.
Along with the breeders meeting a separate meeting on effective utilization of
the available germplasm material, coordination among the institutions may
be conducted.
Develop more linkages with breeding institutes.

• Two DNA markers identified for NPV tolerance are being introgressed into CSR2
through marker assisted breeding for the development of NPV tolerant lines. The
breeding lines are at the BC5-F7 generation. Out of 50 lines, 11 were found tolerant
to NPV.
• Five EST putative markers were detected for NPV tolerance and four markers viz.
Nag34, Nag88, Nag84 and Nag65 were mapped on chromosomes 3, 5, 7 and 19.
