Expected Outcome

1

AIB 02006 MI: 
Improvement of Nistari lines for survival and Silk productivity

Dr. Thangjam Ranjita Devi, Sci-B

June 2020 - May 2024

  • To develop Nistari lines for improved survival and silk productivity
  • To evaluate improved Nistari crossbreeds for productivity traits

22.50

Improved Nistari lines with distinct superiority in survival, BmNPV tolerance, economic traits and silk filament characteristics.

Improved crossbreeds with better productivity by utilizing improved Nistari lines would enhance raw silk productivity in Eastern and North Eastern India.

2

Identification of superior Bivoltine foundation cross as a male component to improve crossbreed productivity in E & NE India
 (RC Approved - Concept Note  -CSB/BER/RCN017):

Dr. V.Lakshmanan , Sci-D

3 years  - (April, 2020 to March, 2023)

To identify superior bivoltine foundation crosses as male component to improve the crossbreed productivity in Eastern & North-Eastern India

7.68.

  • New productive bivoltine foundation crosses will be developed with higher productivity traits (Shell weight: 0.27 to 0.32g; Shell: 18 to 20%)

 

  • Newly developed productive bivoltine foundation crosses when combined with sturdy ruling multivoltines, expected to increase silk productivity particularly in Eastern region and in general at North-Eastern region.

AIB 02009 MI:  Authorization trials of silkworm hybrid, 12Y x BFC1 in Eastern and North-Eastern India

Dr. N. Chandrakanth, Sci-C

August 2020 -  July 2022

  • To evaluate the newly developed Multi x Bi  hybrid, 12Y x BFC1 for generating data for hybrid authorization with the farmers in  Eastern & North Eastern India
  •  

31.613

Improved crossbreed for Eastern & North Eastern region would enable commercialization to enhance the income of the farmers and silk output.

AIB01009 MI: Evaluation of new bivoltine double hybrid, TT21 x TT56 at farmers level for  authorization for commercial exploitation
[Collaborative project with CSRTI-Mysuru]

Dr. N. Chandrakanth, Sci-C

April 2020 to March 2023

  • To evaluate the performance of bivoltine hybrid, TT21 x TT56 in field for productivity and silk quality

5.194

After authorization, hybrid TT21 x TT56 would be commercialized to increase quality raw silk production.

5

AIE06002 MI: Evaluation of bivoltine silkworm genetic resources for tolerance to abiotic stress in selected hotspots

[Collaborative project with CSGRC-Hosur]
Dr. N. Chandrakanth, Sci-C

March 2019 to March 2022

  • To screen and select bivoltine germplasm resources with presence of markers linked to thermo tolerance.
  • To evaluate selected bivoltine germplasm resources against abiotic stress and identify suitable bivoltine breeds to target selected hot spots

0.50

Identification of thermo-tolerant productive bivoltine breed(s) suitable for different hotspot regions.

6

On-Farm Trials of Bivoltine Double Hybrid, (BHP3.BHP2) x (BHP8.BHP9) in E & NE India

Dr. V.Lakshmanan , Sci-D

Two Years  (July, 2020 - June, 2022)

To evaluate the new bivoltine silkworm double hybrid, (BHP3.BHP2) x (BHP8.BHP9) in large scale with farmers of E & NE region.
 

5.22

Large scale evaluation (20,000 to 30,000 Dfls) of new bivoltine double hybrid, BHP DH for two years in different locations of E & NE would generate bulk data on its performance across seasons / locations and would fulfill the protocol requirements to put forth before Hybrid Authorisation Committee for its consideration.
