Current responsibilities:

  • Phenotyping kharif sorghum (grain, dual-purpose, sweet, forage) for climate change (drought & heat stress tolerance) adaptation. and mapping population development for MAS/QTL identification.
  • Physiological basis of assessing the genetic progress in yield potential of kharif sorghum cultivars and parental lines
  • AICRP Sorghum Physiology Coordination as Principal Investigator
  • Other activities – Nodal Officer, Swachha Bharat Mission

Recent major contributions:

  • Quantified the impact of climate change (preflowering drought & heat stress) on dryland sorghum in controlled environments.  Contributed to the development of two sweet sorghum for bioenergy production. Involved in development of five rabi sorghum cultivars (Phule Maulee, Phule chitra, CSV26R, CRS1, CRS4) for medium to shallow soil with drought and heat tolerance traits.
  • Growth and development of Indian tropical sorghum were characterized on 0 to 9 schemes. Identified of selectable and reliable traits to be used for screening germplasm under drought and heat stress condition such as higher green leaf area index, staygreen rating, high apparent leaf density (SLW), SPAD, total chlorophyll content, sink potential (grain number m-2) and drought susceptibility index. Potential sorghum donors indentified include Indore12, 27B, CS3541, SPV1671, CSV27, IS13521, SPV462, S35, SPV922, B35 and E36-1.  
  • Identified the best planting window for sweet sorghum i.e., from June 1 to July 1and high yielding hybrid namely CSH22SS for grain and bioenergy production in dryland areas of semiarid climate. Organized pilot (big-mill tests) with several biofuel industries and produced bioethanol from sweet sorghum. Produced a film (CD), extension flyers on potential sweet sorghum for bioethanol production.

Recent awards and recognitions:

  • Visiting Scientist at Kansas State University (KSU), Manhattan, KS, USA on sabbatical leave for four months (Feb to June 2012). Worked on climate change of dryland sorghum with full financial assistance received from KSU, USA.
  • Invited lectures presented on utilization of sweet sorghum for first and second generation biofuel feedstock at BITS, Hyderabad; MNITs, Nitte; Min of Petrolium, GoI, etc.
  • Received the best poster and oral award (cash) on “sweet sorghum as bioenergy crop” at national seminar, IIT, Chennai (2008) and national millets seminar (2010), NIRD, Hyderabad.
  • Major advisor for guiding PG students (MSc Ag & PhD) of PJTSAU, and ANGRU, Hyderabad and UAS, Benguluru.
  • Fellow, Indian society for Plant Physiology (FISPP), IARI, New Delhi In 2008.
  • Reviewer for external projects in the area of biofuels for DBT, DST and ICAR New Delhi.

Current collaborative activities:

  • UAS (B) , Mandya
