Genomics: Accelerating Genetic Gains

A new green revolution is crucial if the world’s growing population is to be fed. Genomics provides breeders with new tools and techniques to study the whole genome of plants. By studying the genotype and its relationship with the phenotype, more efficient cultivars can be developed that have the greatest potential to increase yield.

Chickpea- Glasshouse screening

Interventions

  •  Decoded genomes of three legumes (chickpea, groundnut and pigeonpea) and two cereals (sorghum and pearl millet) have provided not only vast information on genome architecture and organization but also on genes/genomic regions controlling priority traits in these important crops of smallholder farmers in the semi-arid tropics 
  • Deploying genomics-assisted breeding could strengthen the crop improvement pipeline by increasing the efficiency and speed of precision breeding in all the ICRISAT mandate crops.

nutwheel Impact

  • Developed improved chickpea lines with enhanced tolerance to drought, resistance to Fusarium wilt and Ascochyta blight
  • Developed groundnut lines with enhanced resistance to rust and improved oil quality
  • Improved lines have been provided to national programs.
  • Breeding programs using genes/genomic segments/QTLs associated with priority traits such as biotic/abiotic stress tolerance, yield, etc.
