CIMMYT scientists have had remarkable success in the pre-proposal competition for the Generation Challenge Program’s competitive grants in 2006. A total of 55 pre-proposals were submitted by many organizations. External reviewers have selected 20 of them and GCP Director requested proponents to develop and submit full proposals. CIMMYT has submitted four pre-proposals as Principal Investigator or Co-Principal Investigator and all the four pre-proposals have been selected (100% success rate)! Although we still have to go through the next round of competition (25-35% of acceptance rate) by developing full proposals, it is clear that our scientists have been very successful in pre-proposal development.
