TLI 2012: Chickpea research workplan

  1. 1. Objective 4- CHICKPEA
  2. 2. ActivitiesActivity 1: Utilise genetic diversity to develop breeding and MAGIC populations (Harnessing diversity)Activity 2: Develop genomic resources for enhancing MABC and MARS activities (Genomic resources)Activity 3: Employ MABC and MARS activities to improve superior lines (Drought tolerance breeding)Activity 4: Strengthen capacity of NARS partners (Capacity building)Activity 5: Management and storage of data (Managing data)
  3. 3. Activity 1: Harnessing Diversity Milestones: 1. 8 Parental genotypes for generating pre-breeding populations and MAGIC populations identified COMPLETED 2.
