A participatory crop improvement (PCI) project in Gujarat, India targeted the high potential production system (HPPS) devoted largely to rice and wheat. An NGO, the Action for Social Advancement (ASA), led this project. A new rice variety that was not officially recommended for cultivation in Gujarat greatly reduced farmers' costs of production and has spread widely. Several institutional impacts followed from the project. ASA is now leading projects that are based on the PCI approach, and has recognized the need for changes in regulatory frameworks that control the release and popularization of varieties. ASA is now beginning to actively advocate such changes.
