What is Certified Seed?

Certified seed is produced under strict quality standards to ensure varietal purity, high germination rates, and freedom from contaminants. This process guarantees that farmers receive reliable, high-quality seed for successful crop production.

The Certification Process

• Foundation Seed Source: Certified seed originates from Foundation seed supplied by the University of Wisconsin College of Agricultural and Life Sciences or other approved sources.
• Field Inspection: Growing fields undergo rigorous inspections to verify varietal purity, ensure proper isolation, and detect any weed contamination.
• Laboratory Testing: After processing, samples are tested for mechanical purity, germination rates, and adherence to certification standards.
• Official Certification: Only seed that meets all requirements is labeled with an official Certified Seed tag, providing assurance of quality and authenticity.

Growers listed in the Seed Directory have applied for field inspection. Certification of harvested seed depends on meeting all field and laboratory standards. Note: The Seed Directory is for informational purposes only and does not serve as a solicitation to purchase seed.
