Project Title :Economics of silk production in Assam.
Personnel :Saikia PD, Dutta PC, Buragohain DK, Kolita C, Boruah S, Gogoi B, Borah NC
Project Period :1981-1983
Objectives :
· To study the pattern of silk production and the resources available with the producers for production of silk.
· To assess the quantum of silk production and the cost involved and the pattern of disposal and the price received for it.
· To assess the adequacy of government incentives and technical guidance in developing silk production.
· To suggest ways and means to make the silk cultures an economically viable enterprise.
Results/Recommendations :
· The main problem faced by the silkworm rearers is the scarcity of food leaves for the worms. It is felt that plantation of muga food plants should be taken up under Government schemes in village grazing reserves or other community land under the social Forestry scheme so as to enable some progressive rearers to take up muga silk worm rearing in extensive form.
· It is expected that the introduction and expansion of cultivation of improved variety of Nuni plants, use of HYV mulberry seeds worm, introduction of improved rearing techniques, establishment of silk reeling factors in important silk producing areas will attract the rural people in taking up mulberry silk rearing in extensive form. If proper care is taken the leaf yield of mulberry plantation can be increased to 1200 to 1400 Kg per acre.
· The eri seed grainage, muga seed farms and also sericultural farms set up by the Govt. for providing healthy and disease free seeds to the rearers should be strengthened to cover larger areas. The seed production capacity of these establishment should be enhanced.
· The rearers are still using traditional type of equipment for spinning as well as reeling of cocoons and the productive capacity of these equipments is very low. Providing improved type of Ambar charkha to the eri rearers and establishment of reeling centres in important muga and mulberry silk producing areas will be much helpful in this regard.
· Training should be organized to acquint the farmers in producing good quality of mulberry silk.
· The Central Silk Board has established the muga Raw material Bank at Sibsagar in 1980-81 with a substation at Dhaku akhana at Lakhimpur district with a view to procure muga cocoons from the rearers at reasonable price. Raw materials Bank has selected only Sibsagar and Lakhimpur districts as area of operation.
· The Regional Sericulture Research station, at Titabar has developed new technology of muga rearing called “Cellular” rearing. The rearers should be encouraged to adopt this new technique.
· Adequate publicity regarding the profitability, improved methods of silk culture through rural programme of All India Radio is considered necessary. In view of the importance of the silk industry in the state silk rearing should be included as a compulsory subject in the curriculum in the educational Institutions.

Project Title : Problems and prospects of muga silk production in Assam.
Personnel : Saikia TN, Dutta PC, Baruah S, Borah R
Project Period :1998
Objectives :
· To study the nature of muga silk culture and technologies change if any in recent times.
· To study the costs and returns in muga silk production including the marketing channels of muga silk.
· To identify the problems faced by the rearers.
· To trace the economic benefits derived from the muga silk culture including the future prospects.
· To suggest policy implications on the basis of the findings of the study.
Results/Recommendations :
· The various developmental programmes undertaken so far by the concerned departments of both the state and central governments for muga silk in Assam have already reflected on the rearers under the study. Popularization of the improved technologies through demonstration or publicity media is another important factor to achieve desired results.
· The sericulture department of the state government and the Central Silk Board, under the ministry of textiles, Government of India are two different organizations taking up developmental programmes for muga silk culture in the state co-ordination between these two organizations is maintained only in identifications is maintained only in identification of rearers to be trained by the CSB. The training programmes for muga silkworm rearers conducted by the CSB include only those who are deputed by the sericulture Department of the state Government. Other programmes are executed separately by each of them. It is assumed that coordinated efforts can be made by setting up a coordination committee with members by setting up a co-ordination committee with members of both the organizations. The Central Silk Board is a national organizations while the muga silkworm rearing is a regional enterprise and so the officials in the Central Silk Board obviously shall have to take more time to be familiar with the problems of muga silk culture in the state coordinated efforts with the state sericulture Department in this regard will ease the problem to a great extent.
· Muga silk culture in Assam is dominated by some traditions, beliefs and superstitions which are being prevailed among the rearers from time immemorial. While taking up modernization of the enterprise with developed technologies, these factors shall have to be taken into account, otherwise it may create adverse impact on the rearers. To boost up production and productivity of muga silk in the state, the immediate need is to make adequate provisions for supplying DFLs and suitable worm feeds to the rearers according to their demands. Considering the popularity of muga silk fabrics both in the National and international markets, it is assumed that it will able to occupy an important place in the National economy it is developed.

Project Title :Morphological and biochemical basis of variability in Som (Machilus bombycina) germplasm.
Personnel :Lochan R, Hazarika, Deka PC
Funding Source :CSIR, New Delhi
Project Period :1995-1997
Objectives :
· To analyze morphological variation, phenolic compounds, essential oils, fatty acids present in the leaves of Machilus bombycina.
· To analyze the isozyme variation and foliar chemical constituents in most and least preferred (by silkworm) genotypes of Machilus bombycina.
Results/Recommendations :
· In this study, morphological and biochemical variation were investigated in Machilus bombycina germplasm originated from different muga raring belts of Assam.
· Six foliar characters (leaf area, length of lamina, breadth of lamina, length/breadth ratio of leaf, numbers of veins, length of petiole) showed significant variability among Machilus bombycina genotypes.
· Polyacrylamide gel electrophoresis of five enzyme sytems namely, Malate dehydrogenase (MDH), glutamate dehydrogenase GDH), Acid phosphatase (ACP), Glutamate oxaloacetate transaminase (GOT), Reroxidase (PER) of leaves of Machilus bombycina genotypes revealed no variability for MDH, GDH, GOT and ACP isozymes, while considerable variability was observed for peroxidase isozyemes.
· 19 different peroxidase isozymes (based on mobility) were visible in the gel. The number of isozymes per plant varied between 8 and 18. Peroxidase isozymes were visible in five distinct zones and variability was observed for peroxidase-1, 4 and 5. Peroxidase zones 2 and 3 showed no variability among the genotypes.
· Based on the zymotype similarity, 99 genotypes were grouped into 2 for peroxidase 1; 18 for peroxidase 4 and 27 for peroxidase 5 zones. Cluster analysis revealed that isozyme analysis provides more finer and accurate basis of genetic diversity compared to morphological characters of Machilus bombycina.
· Variation of foliar constituents like protein sugars, phenols, flavonoids, essential oil between most preferred (by muga silkworm) and least preferred genotypes of Machilus bombycina suggested a possible role played by both nutritional and secondary compounds in determining the degree of acceptance of leaves by muga silkworms.
· Six flavonols (including 3 new), 29 essential oils and eight fatty acids were identified from the leaves of Machilus bombycina.
· Based on these results it can be concluded that wide genetic variability exists among genotypes of Machilus bombycina available in this region. Isozymes analysis can be used to measure degree of genetic diversity, to develop genetic markers, to understand the phylogenetic relationship among genotypes. Isozymes provide finer and accurate basis of genetic diversity within the population of a species than morphological characters.

· To know the enzyme activities associated with disease resistance and phytoalexin production.
· To know the phytoalexin production in resistant varieties by spore germination and bioassay methods.
Results/Recommendations :Thirteen mulberry varieties were screened for resistance against leaf spot disease, of which 6 were resistant, 3 were moderately resistant, 2 were moderately susceptible and 2 were susceptible. The biochemical components like phenols, OD phenols and protein contents increased in resistant varieties compared to others. The enzyme activities like ascorbic acid oxidase, catalase PO, PPO, PAL and TAL associated with disease resistance and PA production increased in resistant varieties. The synthesis of PA was high and earlier in resistant variety. The phytoalexin synthesized in resistant variety inhibited the growth of test pathogen, ono-pathogen and also the pathogen itself.
The study indicated that PA were produced in resistant variety, in response to C. moricola infection. PA are antifungal compounds formed in living cells of hypersensitive host in response to parasitic attack and inhibit further development of the pathogen. If PAs are isolated at micro levels can further be injected to the plants and control the disease at early stage of infection.
