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. CSGRC, Hosur • 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. SBRL, Kodathi • 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. 6
• Through suppressive subtractive hybridization (SSH), 29 putative genes involved in the process of diapause were identified • PCR analysis showed that the major pathogens associated with flacherie disease were not DNV1, IFV or CPV. However, inoculation of silkworms with DNV2 revealed typical flacherie disease symptoms. Decisions: Expedite the formation of the research project on DNV-resistant transgenic silkworm development in collaboration with Dr Mita and Dr. Kadona on priority. Provide inputs for the silkworm breeders during Breeders’ Meet to plan marker assisted breeding programme clearly indicating the utility of the technologies emanated from the research projects conducted at SBRL. The SBRL, Kodathi must prepare a road map of their activity with a clear vision. The Director of the Institute should ensure that the outcome of the projects undertaken by SBRL is put into effective use by the Institutes under CSB. This will add a feather in the cap of not only the Director, SBRL, but also that of the Directors of other Institutes under CSB. SSTL, Kodahti • Techniques suitable for preserving eggs of Nistari, Nistari x NB4D2 and Nistari x CSR2 up to 80 days (20 + 60) without affecting hatching, cocoon yield and reeling parameters were developed. • P2 layings of CSR2, CSR4, CSR6, CSR26 & CSR27 were preserved for two year schedule along with regular schedules of 4, 6, 9 months. • Constructed a solar passive energy based model rearing house. • 573 candidates sponsored from DOS of Karnataka, Tamil Nadu, Andhra Pradesh and West Bengal, CSB, NSSO were trained besides those under and Third Country Training Programme. Decisions: A meeting is to be conducted with R&D institutes and Director (Tech) to finalize the studies pertaining to identification of alternative male parent in place of CSR2 for the production of cross breeds. CTR&TI, Ranchi • Characterized 231 accessions of Terminalia sp., for 55 traits and a catalogue were prepared. • Six accessions of T arjuna and four accessions of T. tomentosa were found superior to others in their qualitative and quantitative characters. • 140 accessions of Terminalia were found tolerant to powdery mildew and black nodal girdling diseases. • Feeding of Arjun leaves treated with 20ppm of β-sitosterol indicated significant increase in larval weight, survival and commercial cocoon characters over control both under indoor and outdoor conditions. • Field trials of the evolved BC-IV line of Andhra Local yielded 35 cocoons/dfl which was better than the parents, Andhra Local (12/dfl) and Daba TV (20/dfl). • Tasar Amrit tested at farmer’s level yielded 93-95 cocoons/dfl. 7
