Seed Laboratory



What is the purpose of the seed laboratory?

The MCIA laboratory tests seed for quality. Germination, physical purity—including other crop and weed contaminants—varietal verification, vigor, and herbicide tolerance tests are conducted by the lab, as well as other crop-specific tests.


Who determines how seed is tested?

The MCIA seed laboratory follows testing rules established by the Association of Official Seed Analysts (AOSA). These rules, used by regulatory agencies and commercial labs throughout the U.S., set the standard for seed testing in North America and are recognized internationally.


Why should my seed be tested?

Seed testing is the final step in the seed certification process. The test results will be used to verify that the seed standards have been met for that particular crop and seed class. Seed lots certified by MCIA are required to be tested at the MCIA seed laboratory, except for native species, which may be tested at MCIA or authorized labs. Testing information can also be used for labeling and/or quality assurance. Service testing is available for unconditioned seed and seed that is not in the certification program. A host of tests offered, including germination, vigor, purity, and moisture, can help a seed producer, seller, or buyer assess seed quality.


How do I submit samples?

Sample bags are available from the MCIA office for submitting your samples. Fill the bag up to the top line for large-seeded agronomic crops, and to the middle line for most natives, grasses, and small-seeded legumes. Include an MCIA Sampling Report, available on our website or from the MCIA office, to provide information about your seed lot. The form is required for certified samples and is beneficial for service samples.


What should I look for after testing?

Seed tested as part of final certification will receive a Seed Certification Report, indicating the test results and a passed or failed status. Preliminary samples, carryover seed, and non-certified seed will receive a Laboratory Report of Analysis, which will indicate the results of the tests requested. You can receive preliminary and final results by e-mail, and a final report will be mailed to you.
