Current responsibilities:

  • Development of sorghum cultivars for lignocellulosic biofuel production through marker-assisted pyramiding of brown midrib genes.
  • Identification of genomic regions associated with grain Fe & Zn and grain quality traits in sorghum.
  • Development of DNA markers in little and kodo millet.
  • Officer In-Charge, Off-Season Nursery (OSN), ICAR-IIMR, Warangal.

Recent 3 major contributions:

  • Developed low lignin sorghum in the genetic background of dual purpose sorghum varieties (CSV 20 and CSV 27) through marker-assisted gene pyramiding of brown midrib genes for further evaluation.
  • Identified 16 transcripts that were differentially expressed in hybrids and their parental lines. Also identified 10 grain yield heterosis-related genes in kharif sorghum through real-time PCR.
  • Developed genome-wide (GATA)n motif-based SSR markers and intron length polymorphism (ILP) markers in sorghum.
  • Identified 30 SSR markers having the potential for the prediction of grain yield heterosis in sorghum

Recent awards and recognitions:

  • Awarded a three-year research project under Rapid Grant for Young Investigators (RGYI) scheme by the Department of Biotechnology (DBT), Govt. of India during 2010.
  • Recognized by Osmania University to guide Ph.D. students in the Department of Genetics.
  • Member, Research Advisory Committee (RAC) of Agri Biotech Foundation, Hyderabad.
  • Reviewer for research papers/reviews in PLoS One and Frontiers in Genetics.
  • Resource person for trainings conducted at the ICAR – Indian Institute of Millets Research, ICAR – Indian Institute of Rice Research, ICAR – Indian Institute of Oilseeds Research, ICAR – National Academy of Agricultural Research Management, Hyderabad and Tamil Nadu Agricultural University, Coimbatore.
  • Evaluator of the Ph.D. thesis in Biotechnology from JNTU, Hyderabad; Genetics from Osmania University, Hyderabad and Molecular Biology and Biotechnology from Professor Jayashankar Telangana State Agricultural University, Hyderabad.

Current collaborative activities:

  • DBT funded collaborative research project with Jawaharlal Nehru Technological University, Hyderabad entitled “Development of sorghum genotypes suitable for lignocellulosic biofuel production through marker-assisted gene pyramiding of brown midrib genes”.
