In Indonesia, farmers used to collect seed from the best plants for sowing but the changed with the Green Revolution and the introduction of improved varieties, farmers have became plant-breeders. These farmers and others have been trained in plant breeding at a farmer field school (FFS), a program of the Center for Genetic Resources, Agricultural Wageningen University. The training has provided farmers the confidence in developing plants and reduce dependency on government seeds. The farmer-breeders learned to select and breed self-pollinating crops. The grain selected for seed was stored in the shops, wrapped in plastic bags, sold by the shop-owners, and purchased by farmers in the beginning of each planting season.
