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.
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.
