Current responsibilities:

  • Parental line diversification and improvement towards development of hybrids with higher yield and better quality for rainy (kharif) and post-rainy (rabi) sorghum
  • Varietal improvement for higher yield and better adaptability in rainy (kharif) and post-rainy (rabi) sorghum
  • Genetic improvement of barnyard millet for higher yield and tolerance to stresses (biotic and abiotic)
  • Application of genomics tools towards improvement of sorghum and barnyard millet
  • Co-ordination of grain sorghum research under AICSIP as Principal Investigator (Grain Sorghum Breeding)

Recent major contributions:

  • Projected the genetic gains in Indian sorghum improvement programme over four decades vis-a-vis yield gains in top 10 sorghum producing countries. The study indicated need to strengthen post-rainy sorghum improvement programme in India. Study also highlighted need to strengthen hybrid breeding in India and elsewhere.
  • Developed a reference set of 96 geneotypes for drought studies with 29 identified sources of tolerance. Identified over 50 thousand genome-wide sequence variants to be deployed in genome selection. Registered 45 sequences of genes related to abiotic stress response from different genotypes with NCBI.
  • Identified high crossover genotype ´ environment interaction and delineated mega-environments among testing locations across India, which helps in efficient allocation of testing locations and better utilization of scarce resources.
  • Using ICT developed a web-based automation system for All India Coordinated Sorghum Improvement Project (Copyright no. SW7971/2014). This has enhanced the efficiency of trial execution, monitoring, data retrieval, analysis, and preservation of metadata. The system is now being adopted in other All India Coordinated Research Projects.
  • Developed and contributed 10 grain sorghum hybrids, 8 grain sorghum and two forage sorghum varieties for all India testing.

Recent awards and recognitions:

  • Fellow, Indian Society of Genetics & Plant Breeding, New Delhi, 2014
  • NE Borlaug Fellowship (USDA) 2010
  • JSPS Post-doctoral Fellowship for Foreign Researchers, 2003
  • BOYSCAST Fellowship, 2003
  • CSIR Scientist Travel Fellowship, 2002
  • Indian Science Congress Association Young Scientist Award, 1999
