The majority of the seed production and supply continues to be in farmer-managed systems. Formal seed systems leave smallholder farmers, particularly women, in remote areas with limited access to quality seed of preferred varieties. The lack of quality seeds has become a major constraint in varietal replacement affecting the farmers’ productivity. This is particularly true in the production of seed of open-pollinated crops and varieties which the private seed sector has generally not taken up. Due to several constraints, the public seed sector is largely unable to meet the demand for quality seed. There are also concerns about the quality of seed in farmer-managed and community-based systems due to the lack of certification.
