Seed Certification Process in Ghana

Seed quality is the foundation of everything in agriculture. A farmer can apply the best fertiliser, manage water perfectly, and use the most effective crop protection programme, but if the seed is poor quality, infected with disease, or mislabelled, the season is compromised from day one. Ghana's seed certification system exists to prevent exactly this outcome: it provides a quality assurance framework that farmers and the market can trust.

Understanding this system is essential for anyone involved in seed production, importation, or distribution in Ghana. Whether you are a seed company seeking to register a new variety, a producer generating certified seed for sale, or an importer bringing in seed from another country, the PPRSD processes described in this article apply to your business.

The Legal Framework: Seeds Act 2010 (Act 785)

Seed certification in Ghana is governed by the Seeds Act 2010 (Act 785) and the associated Seed Regulations. The Act establishes the Plant Protection and Regulatory Services Directorate (PPRSD) as the national seed regulatory authority. PPRSD is responsible for variety registration, seed certification, seed quality control, and the enforcement of seed quality standards across the market. It also manages Ghana's adherence to the International Union for the Protection of New Varieties of Plants (UPOV) framework for plant variety protection.

Variety Registration: The Starting Point

Before any variety can be certified or legally sold in Ghana, it must be listed on the National Variety List. New varieties are registered through a Distinctness, Uniformity, and Stability (DUS) assessment and a Value for Cultivation and Use (VCU) evaluation. The DUS assessment confirms that the new variety is genuinely distinct from existing registered varieties, uniform in its characteristics, and stable across growing seasons. The VCU evaluation confirms that the variety performs at least as well as existing comparable varieties under Ghanaian conditions.

Both assessments are conducted over a minimum of two growing seasons. For annual crops, this means at least two years of trial data before a variety can be registered. For tree crops, the timeline is considerably longer. Trials are conducted at PPRSD-approved locations under standardised conditions. Applicants pay a registration fee and contribute to trial costs. The full variety registration process from application to listing typically takes two to three years for annual crop varieties.

Seed Certification Classes

Ghana's seed certification system uses the internationally standard seed class hierarchy. Each class has defined standards for genetic purity, physical purity, germination rate, moisture content, and freedom from seed-borne diseases.

• Breeder Seed: produced by or under the direct supervision of the plant breeder who developed the variety. It is the highest-purity class and is the source from which all other classes are multiplied.
• Foundation Seed: multiplied from Breeder Seed under strict supervision. Foundation Seed is the seed that commercial seed companies use to produce Registered and Certified Seed for sale to farmers.
• Registered Seed: multiplied from Foundation Seed. A transitional class used in Ghana for certain crop species and situations.
• Certified Seed: the class of seed available to farmers. Produced from Foundation or Registered Seed under a certification scheme that includes field inspection during the growing season and laboratory testing of the harvested seed.

The Certification Process for Seed Producers

To produce certified seed for sale in Ghana, a seed company or producer must be registered with the PPRSD as a seed producer. The process begins before planting: you notify the PPRSD of the crop, variety, field location, field history, and source seed class. An inspector verifies the source seed and the field conditions before planting is approved. During the growing season, the field receives one or more inspections from PPRSD inspectors who verify varietal purity, the removal of off-types, isolation distances from other crops of the same species, and freedom from seed-borne diseases.

After harvest, seed samples are submitted to the PPRSD laboratory for germination testing, physical purity analysis, moisture determination, and seed health testing. If the field inspection and laboratory results both meet the required standards for the relevant seed class, the PPRSD issues a seed lot certification and provides official labels. Certified seed must bear official PPRSD certification labels. Seed sold without these labels cannot legally be represented as certified.
