Crop improvement has been one of the strong, continuous programs in the Mekong Delta for major crops, especially rice. However, most breeding programs have been set and designed by breeders, neglecting the role of users: farmers and farming communities. Farmers have been the passive users, receiv...

In this paper CONSERVE's experiences in handling two research approaches in participatory plant breeding in rice are discussed: researcher-managed or on-station trials (OSTs) and farmer-managed trials. OSTs are done on CONSERVE's farm. CONSERVE crosses (CC) were used as materials for evaluation o...
