Eri Research & Training Institute is a R&D institute in the
field of muga and eri culture. It is under the control of
Central Silk Board, Ministry of Textiles, Govt. of India. The
institute has been successfully undertaking entire gamut of R&D
activities to cater the needs of the on-farm and post-cocoon
sector of Muga and Eri sericulture. Muga and Eri culture is a
rural based industry of all the North Eastern states and parts
of West Bengal.
of late, has spread to other parts of the country owing to its
gainful additional income generating potential to the castor and
tapioca cultivators. In recent years, infrastructural facilities
have been strengthened in the institute for conducting basic and
applied research in the frontier areas. The priority of the
research activities is based on the evaluation of cost effective
technologies towards increasing the productivity of Muga and Eri
silkworms and thereby transforming these cultures from the state
of traditional culture to a profit making and sustainable
golden silk is a wonderful gift of nature, known for its glossy
fine texture and durability. Due to its low porosity, the Muga
yarn cannot be bleached or dyed and its natural golden color is
retained. This silk can be hand-washed with its luster
increasing after every wash. The silk is obtained from semi
domesticated silk worm viz. Antheraea assamensis. The
Muga mekhela-chador is a traditional dress of Assamese
women for Bihu dances and weddings. It is in demand in
Japan to make kimonos, and also high demand in countries like
U.S., Greece, Germany, South Africa and France. The
golden-yellow Muga silk of Assam has been granted Geographical
Indication (GI) registration by the GI Registry in Chennai. It
has been identified as a silk of given quality, reputation and
characteristic, attributable to the geographical area of Assam
since time immemorial.
also known as Endi or Errandi, is a spun from
open-ended cocoons, unlike other varieties of silk. Eri silk is
the product of the domesticated multivoltine silkworm, Samia
ricini that feeds mainly on castor leaves. This silk behaves
like cotton and warmth like wool. Due to its coarseness, eri
silk yarn can be blended with other yarns and made suitable for
manufacturing of all varieties of fabrics, lighter to heavy
fabrics, inner ware, dress material, ornamental fabric, thicker
fabric like chadder, wall hangings, furnishings and hosiery
Region of India with tropical to temperate climate holds
indomitable positions in the global sericultural map having all
the four varieties of silk viz. Mulberry, Oak Tasar, Eri and
Muga. Sericulture in this region provides gainful occupation to
nearly about 1.80 lakh families. However, the strength of the
region lies mainly with muga and eri culture. Eri culture is
mainly practiced in Assam, Meghalaya, Arunachal Pradesh,
Nagaland and Manipur of North East India. Of course, now-a-days
this culture is spreading to certain non-traditional states of
India viz., Andhra Pradesh, Gujarat, Madhya Pradesh,
Chhattisgarh, Tamil Nadu, Karnataka, Maharashtra, Uttaranchal,
Uttar Pradesh, Jharkhand, Bihar, West Bengal, Orissa and Sikkim.
The largest share (above 90%) of eri silk production of India is
contributed from N.E. India and it shares 77% of the total
non-mulberry raw silk produced in the country.
golden yellow muga silk, Assam, the easternmost state of the
Indian Union, has the unique distinction, though wild
counterpart of muga silkworm is found in the foothills of
Meghalaya, Nagaland and Arunachal Pradesh. A good number of
allied species of Antheraea are also found in NE
India in their natural habitat.
In order to
provide R&D support in muga and eri silk industry in North East
India, Central Silk Board (CSB), Ministry of Textiles, Govt. of
India established Central Muga Eri Research Station at Titabar,
Assam in 1972, which was later bifurcated into Regional
Sericultural Research Station, Titabar for mulberry research and
Regional Muga Research Station (shifted to Boko) during 1982 for
exclusive research on muga. Again during 1987, CSB established
an exclusive Research and Training Institute for muga and named
as Central Muga Research & Training Institute at Lahdoigarh,
Jorhat. It came into being as a full-fledged Research & Training
Institute in 1999 and during the same year, it was renamed as
Central Muga Eri Research & Training Institute with a mandate to
serve as the apex R&D institute for both muga and eri.
