Many countries only allow seed of registered varieties to be legally produced and sold in the market. Due to strict requirements regarding the characteristics (e.g., distinctness, uniformity, and stability) and performance (e.g., outperforming high-yielding varieties under standardized growing conditions) for varieties to be released, this implies that many farmers' varieties are confined to the spheres of the informal sector as ‘potential planting materials’: their production, use, exchange, and trade remain unregulated, largely unsupported, and their importance underestimated.

开发农民品种登记制度


许多国家只允许注册品种的种子在市场上合法生产和销售。由于对要发布的品种的特性（例如，独特性、均匀性和稳定性）和性能（例如，在标准化生长条件下的表现优于高产品种）有严格的要求，这意味着许多农民的品种作为“潜在的种植材料”被局限于非正规部门的领域：它们的生产、使用、交换和贸易仍然不受监管，在很大程度上没有得到支持。 他们的重要性被低估了。
