In Europe, the commercial seed supply system is highly organised and controlled. European law on seed marketing has evolved over the years to ensure that only uniform seeds for industrial farming can be sold on the market, condemning farmers' seeds and traditional varieties to the black market if not complete illegality. Together with strong intellectual property rules and the production of hybrids, European seed laws lock farmers out of the seed system.
