  Agri-Bioresources Augmentation Division (ABA)


  • Conservation, improvement and utilization of bioresources for natural resins and gums
  • Research on conservation of bioresources related to medicinal and other high value plants for developing higher order processing systems

Division building


The Division has scientists from the disciplines of Agriculture Entomology, Seed Technology, Agriculture Biotechnology, Genetics and Plant Breeding, Plant Physiology and Plant Biochemistry. It houses well equipped laboratories of Biotechnology, Physiology and Systematic Entomology. The division houses the project coordinating unit of Network Project on Conservation of Lac Insect Genetic Resources which is coordinating and networking research activities pertaining to conservation of lac insect genetic resources at twelve centers including lead center at ICAR-IINRG, Ranchi.

  Available facilities / instruments
  Thermal cyclers, QPCR machine, Lyophilizer, Freezer, HPTLC, Nitrogen analyzer, Stereo zoom microscope with camera etc.

Major technologies developed

  • Early kusmi breed- Semialata combination for kusmi lac production
  • Late kusmi breed- Ziziphus mauritiana (ber) combination for kusmi lac production
  • Lac cultivation on Cajanus cajan (arhar)
  • Development of high density plantation of ber for lac cultivation
  • Kusmi lac production technology on Prosopis juliflora during winter crop season
  • Summer season (jethwi) sticklac production on ber trees with the help of pitcher irrigation
  • Moisture conservation through organic mulching for establishment of ber plantation under rainfed condition
  • Lac- host plant suitability index
  • Early detection of key parasitoids in field collected lac insects using molecular approach
  • Development of rhizobial bio-fertilizer for Flemingia macrophylla
  • Primary culture of lac insect cells Weather based prediction model for abundance of key parasitoid of lac insect Aprostocetus purpureus
  Services provided
