Certified seed or farm-saved seed? A commercial buyer comparison
Certified seed comes with documented varietal identity and lot quality under an official scheme; farm-saved seed relies on your own testing and may be restricted for protected varieties or not permitted for hybrids to reproduce true to type. Compare the evidence and legal position, not only the price.

Symptoms to record
- Saved seed is being considered to cut costs.
- Previous saved lots varied in performance.
- The variety’s protection status is unclear.
Diagnostic evidence path
1. Is saving legally allowed for this variety?
Check plant variety protection rules and any farm-saved seed royalty that applies in your jurisdiction.
2. Will the seed reproduce true to type?
F1 hybrid seed does not breed true; saved seed from hybrids is not equivalent to the original variety.
3. Is the saved lot tested?
Arrange germination and purity testing with a qualified laboratory before sowing.
4. What does certification add?
Certification documents varietal identity and quality for the lot under the scheme; it does not guarantee field performance.
Worked example — stated assumptions
Hypothetical decision: a grower compares certified seed at a higher unit price with a saved lot testing 78% germination. Using the cost-per-hectare method, the saved lot needs more seed per hectare plus testing and cleaning costs. The comparison is incomplete until legal status and lot purity are confirmed.

When expert help is needed
Ask the national variety-protection office or a legal adviser about saving rights, and a laboratory about testing. SeedMatchGroup is not a regulator.
Buyer questions
Is saved seed always cheaper?
Not after testing, cleaning, treatment and higher sowing rates are included.
Can I save hybrid seed?
It will not reproduce the hybrid true to type.
Does certification guarantee yield?
No. It documents identity and lot quality only.
From observation to a private seed request
Free planning arithmetic. Starting values are hypothetical, not a recommended stand or lot acceptance threshold. Nothing is saved or sent until you submit a brief.

Target plants ÷ (germination fraction × post-germination establishment fraction × applicable purity fraction). Confirm the unit basis; do not double-count physical purity or field losses. Zero germination cannot be compensated by ordering more.
