Sericulture New Technologies

There are more than 500 sericulture technologies developed in India. For details please visit http://kssrdi.org/technology/index.asp.

Some of the Technologies are listed below:

1.MULBERRY IMPROVEMENT :

  1. Varieties for Irrigated conditions

    i. S-36 - This variety was referred in 1986. It yields 45 MT/ha/yr.
    ii. V-1 - The variety was released during 1997. It produces about 60 MT/ha/year.
    iii. Genotype No. 2 - The genotype is appropriate for raising a garden exclusively for rearing young age silkworms. It produces 35 per cent more chawki leaf as compared to S-36.
    iv. Genotype No. 4 - Developed for cultivation in an irrigated environment. It is most suitable for late age rearing of silkworms.
    v. Vishwa, Vihala, Suvarna-1, Suvarna-2, Suvarna-3.

  2. Varieties for Rain fed conditions:

    i. S-13 and S-34 - It was released during 1990 and yields 10-12 MT/ha/yr.

    ii. AR-10 - It was developed in 2001 and produces 9.28 MT/ha/yr.

  3. Varieties for Alkaline conditions.

    i. Kanva-2 x Kosen - Developed during 2001, it yields about 44 MT of leaf yield /ha/ year compared to Kanva-2, which yields only around 28.5 MT/ha/year.

2.MULBERRY CULTIVATION :
  1. Drip Irrigation system :

    This system saves around 40 per cent more water compared to surface irrigation without negatively affecting the leaf yield.

  2. Use of PSB in mulberry cultivation :

    The use of phosphate solubilising bacteria ensures that farmers may apply rock phosphate rather than expensive SSP in mulberry cultivation. A net saving of Rs.1745/ha/yr towards phosphatic fertilizer is usually gained.

  3. Vermicomposting:

    This result in self-sufficiency in production of organic manure and less dependence on chemical fertilizers.

  4. Chawki garden technology :

    32 batches of chawki rearing could be conducted in a year under a four-plot module. This makes possible a harvest of eight crops annually from each plot of half acre size @ 5000 dfls per batch.

  5. Paired row system of plantation :

    It lowers manpower utilization for intercultural operations. The quality of the leaf increases with a reduction in pests and diseases.

  6. Intercultivation in Mulberry :

    It supplements the farmer's income. Short duration seasonal crops particularly leafy vegetables are recommended.

3. MULBERRY PROTECTION:
  1. Bionema :

    A bionematicide for the control of root knot disease.

  2. Raksha:

    A biofungicide used to control root rot disease.

  3. Nursery-Guard :

    A biofungicide for managing other nursery diseases.

  4. Management of foliar diseases of mulberry :

    i. Leaf spot (Cercospora moricola) - Foliar spray of 0.2 per cent Bavistin (Carbendazim 50 per cent WP)

    ii. Powdery mildew (Phyllactinia corylea) - Foliar spray of 0.2 per cent Bavistin/Karathane (Dinocap 30 per cent EC)

    iii. Leaf rust (Cerotelium fici) - Adoption of wider spacing and avoiding delay in harvesting of leaves. Also, foliar spray of 0.2 per cent Kavach (Chlorothalonil 75 per cent WP)

    iv. Bacterial blight (Pseudomonas syringae pv. mori / Xanthomonas campestris pv. mori) - Step-up pruning (30 cm above the ground) during rainy season in high rainfall areas. Also spray 0.2 per cent Streptomycin or Dithane M-45 (Mancozeb 75 per cent WP) within safe period of 2-3 days.

  5. IPM against mealy bug causing tukra in mulberry :

    The IPM reduces the tukra occurrence by 70 per cent.

4.SILKWORM IMPROVEMENT:
  1. Bivoltine hybrids:

    i. CSR2 x CSR4 - This is a productive hybrid. The main characteristics of a hybrid are high cocoon shell ration (24-25 per cent), raw silk recovery (19-20 per cent) and a yield of an average of 74.6 kg/100dfls with international grade (3A-4A).

    ii. CSR18 x CSR19 - This is a robust hybrid. 3 lakh dfls were tested. They achieved an average yield of 65-70 kg even in the summer, in the States of Andhra Pradesh, Karnataka and Tamil Nadu. An average renditta of 5.5 to 6.0 and silk grade of 2A-3A has been realized in the field.

    iii. Double Hybrids - This hybrid displays high fecundity besides survival of more than 95 per cent and raw silk more than 20 per cent. It was widely accepted by farmers in Andhra Pradesh, Karnataka and Tamil Nadu. The average yield is around 65-70 kg/100 dfls.

    iv. GEN 3 x GEN 2 - This hybrid has been created through the new strategy of molecular marker assisted selection by transferring high activity amylase genes from the polyvoltines into the genetic background of productive bivoltine breeds. The hybrid has documented an average yield of 64 kg/100 dfls through distribution of more than 70,000 dfls.

    vii. Nandi (SL) - CSR2, CSR8 - The hybrids comprise of sex limited male parents. This allows P1 farmers to sell only the white cocoons (male) to the grainages while the yellow cocoons (female) are sold to reelers.

    viii. NK2 x HND bivoltine hybrid for favorable conditions for higher productivity.

    ix. BRO-2 X NP4 , bivoltine hybrid for Summer seasons for higher crop stability.

    x. KSO-1 x SP2 robust silkworm race suitable for even summer conditions.

  2. Multivoltine hybrids:

    i. Cauvery: BL 67 x CSR 101 - This is a multi x bi hybrid meant for irrigated areas. It produces A-2A grade silk with renditta of 6-6.5 yields with an average yield of 65-70 kg/00 dfls.

    ii. MH1 x CSR2, robust high productive cross breed producing white silk.

    iii. KS-10, an anti-diapausing silkworm race converts BV to MV.

    To offer optimum environmental conditions during incubation of loose eggs. More than 90 per cent hatching is attained.

  2. Rotary mountage :

    It lowers the percentage of defective cocoons and floss and improves the cocoon quality. This results in greater reelability and silk grade (2A-3A). Cocoons harvested from rotary mountages fetch around Rs.20-30 per kg.

  3. Cocoon Harvester :

    This wooden harvester saves time and labour as cocoons do not have to be individually harvested from rotary mountages. Model Rearing Houses - These rearing houses have been designed for various agro-climatic conditions and methods of rearing.

  4. Chetena (Phytoecdysteroid developed by the KSSRDI for synchronized maturation of worms) :

    Spraying the solution to the fifth instar larvae (after sample spinning) enhances the spinning behavior and all the larvae of the batch spin cocoons simultaneously the next day.
