Salient Achievements

  • Registered 15 genetic stocks for various important traits in legumes. Many of these are being used in national crossing programs for crop improvement.
  • Developed cores in mungbean and ricebean through phenotypic characterization of entire genebank collections of these crops.
  • 5084 accessions of chickpea phenotype for agro-morphological traits.
  • Over 5000 accessions of chickpea screened for nematode resistance and identified resistant lines which are being used for advanced molecular studies.
  • Over 3500 accessions of chickpea evaluated for drought stress under field conditions and identified promising lines which are under validation.
  • Over 4,500 accessions of mungbean germplasm and 1750 accessions of urdbean germplasm screened for Mungbean Yellow Mosaic Virus, a most devastating disease of both the crops, and identified some promising donor lines.
  • Over 4,200 accessions of mungbean and 850 accessions of urdbean were characterized for important agro-morphological traits and identified trait-specific promising germplasm lines.
  • Characterized around 1800 accessions of ricebean ( umbellata), a potential pulse crop for climate resilience, for various agro-morphological traits and identified important donor trait specific lines.
  • 1,683 accessions of mungbean evaluated for summer heat stress and identified promising heat-tolerant mungbean germplasm lines.
  • Over 2,200 accessions of chickpea germplasm evaluated for important diseases like ascochyta blight, fusarium wilt, botrytis gray mold, dry root rot, collar rot, and drought. For traits like ascochyta blight, & fusarium wilt novel donors were identified.
  • Advanced around 250 interspecific derivatives of lentils from F4 to F10 generation, which are currently being distributed to the lentil breeders, and varieties were also released.
  • Interspecific crosses in Vigna were done to introgress economic traits from wild Vigna to the mungbean and urdbean genomes. Some of the successful interspecific crosses are radiata × V. umbellata & V. mungo × V. stipulacea.
  • Mapping populations for various economic traits heat stress, high moisture stress, MYMV resistance, lodging tolerance, maturity period, pod length, and seed size in mungbean, and urdbean are being advanced for developing RILs.
