Page 2: TLI 2012: Chickpea research workplan

Activities

Activity 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
