Current responsibilities:

  • Improvement of disease resistance in millets and management
  • Profiling of finger millet blast pathogen and management with host resistance and supplements
  • Planning, execution, reporting and improvement of AICRP sorghum pathology programme as principal investigator

Recent 3 major contributions:

  • First time developed artificial screening technique for identification of resistance against pokkah boeng of sorghum.
  • First time developed charcoal rot rating index for precise measurement of the disease. Presently the index is being used in AICRP sorghum for improving reliability of multi-location screening.
  • First time reported anatomical markers for assessing charcoal rot resistance in sorghum. It was useful for rapid preliminary screening of rabi sorghum genotypes.
  • First time identified resistant sources for Fusarium grain mold in sorghum.
  • Collaborator in release of two kharif sorghum varieties CSV36 and CSV39 for all India cultivation.
  • Registered 14 grain mold resistant and one charcoal rot and drought tolerant line in NBPGR.
  • Registered two superior male sterile line [SLA-9 & SLB-9 (INGR 15063)] and [SLA-29 & SLB-29 (INGR 15064)] in NBPGR.
  • Accessioned agriculturally important five Fusarium strains and one Bacillus strain at NBAIM.
  • Identified and developed biocontrol agents (Pseudomonas chlororaphis SRB127; Bacillus subtilis SRB28) for suppression of stalk rot and stimulation of sorghum plant growth in sorghum.

Recent awards and recognitions:

  • Fellow in professional society: Awarded Fellow of Indian Phytopathological Society (FPSI)
  • Research Supervisor: Faculty of Science, Osmania University, Hyderabad
  • Associate Editor: Indian Phytopathological Society, New Delhi
  • Reviewer: National & International journals with Springer & Elsevier; ICAR & IPS, New Delhi
  • Best poster: International conference organised by IPS during 2010 at New Delhi.

Current collaborative activities:

  • Collaborative project with PC Unit (Small millet) GKVK, Bengaluru on finger millet blast
  • Collaborative project ICAR-ICRISAT in pearl millet blast
  • Collaboration with SAUs on AICRP-Sorghum pathology programme
