India’s Central Silk Board develops new varieties of silkworm seeds

The Central Silk Board (CSB) has developed new groups of silkworm seeds of mulberry and Vanya silk. These silkworm groups are expected to enhance the income of farmers with improved productivity and quality.

This silkworm range will aid tribal farmers belonging to various parts of the country such as Jharkhand, Chattisgarh, West Bengal, Maharashtra, Madhya Pradesh and Uttar Pradesh as they can get 52 kilograms of cocoons per 100 disease free layings (dfls). Central Silk Board (CSB) is a statutory body of the Ministry of Textiles.

Additionally, Multivoltine x Bivoltine mulberry (PM x FC2), a hybrid group of silkworm, can make 60 kilograms per 100 dfls. This group of silkworms is said to be more productive than the earlier PM x CSR. The high-quality silk and significant egg recovery make this race more appropriate for farmers.

For the farmers in Arunachal Pradesh, Assam, Bihar, Maharashtra, Madhya Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Orissa, Sikkim, Uttar Pradesh, Uttarakhand and West Bengal, eri silkworm (C2) race has been termed more sufficient than the local breed. Silkworm breeds for a particular agro-climatic location are necessary for accelerating the productivity of cocoons.
