As harvest season winds down, the Seed Science Center’s Seed Quality Testing Lab shifts into high gear, processing thousands of samples to ensure the seeds planted next spring are ready to thrive. From purity checks to trait testing, every test plays a role in shaping next season’s success.
“We conduct tests that indicate the quality of seeds as it relates to germination, the physical purity, and the presence of GMO traits,” explained the lab’s manager, Jessica Blake. “For corn and soybeans, customers can expect the purity analysis within the first 24 hours from the time it was received.”
Germination and trait tests follow quickly, often planted within 24 hours of receipt, meaning even complex samples are planted within 48 hours of being received. Blake says, after that, it’s a waiting game until the sample can be read seven days later.
To help clients stay informed, the lab’s CySeed Online system enables them to track the status of their samples and access the results at their fingertips before we send the official report.
As demand ramps up after harvest, organization and efficiency are critical.
“It’s important to get an idea about seed quality as soon as possible in order to have more time to make decisions about how the seed can be marketed,” Blake noted. “Farmers and companies can submit samples anytime, but earlier is always better.”
The federal Seed Act allows a nine-month window after testing, during which a germination test remains valid for sale. However, some states require that the germination test be no more than six months old, especially for soybeans and other legumes, due to the rapid deterioration that can occur in storage.
Despite the seasonal rush, accuracy never takes a backseat. The lab first achieved ISO 9001 certification in 2007 and has since transitioned to ISO 17025 Lab Accreditation.
“All seed analysts participate in available referees and proficiency tests, not just our certified seed analysts,” said Blaker. “This ensures that we are producing consistent results not just within our own lab but also compared nationally across labs.”
However, Blake also notes that success begins with the sample itself.
“Our website has an entire section dedicated to submitting samples, along with downloadable, printable, and digital submission forms to best meet your needs,” Blake said. “There is nothing more frustrating than trying to send a sample to a lab, only to find a huge corporate website without any specific information.”
A common mistake, Blake noted, is not sending enough seed. For corn and soybeans, which require a purity and noxious exam, it’s best to send in two times the minimum weight for the test. That means 1000 grams instead of the 500-gram minimum, allowing for proper mixing and dividing.
“Don’t be afraid to give us a call or send us an e-mail with any questions,” Blake said. “We are very quick to respond to customers and believe that you cannot overcommunicate.”
However, testing isn’t just about compliance; it’s about empowering informed decision-making. For example, some tests, such as the Saturated Cold test, are sent in just before planting time. The results of that test will likely determine which lots can go in the ground first, because the lots with high Saturated Cold test results can withstand the cold, wet spring conditions the best.”
During peak season, the lab hums with energy. Blake compares it to a kitchen during the dinner rush hour.
“Samples come in like raw ingredients, and everyone’s just trying to prep and process them on time,” Blake said. “In the end, the report goes out like a finished plate, and most folks never see the scramble it took to get there.”
When workloads increase during the winter months, staff members often work weekends to ensure that results are delivered within the expected timeframe. Collaboration is essential—every team member contributes wherever needed, whether that means planting samples, cleaning equipment, or preparing materials to keep the testing process moving efficiently. But amid the rush, there’s still room for wonder.
“I can literally hear people bonding over seeds in the lab adjacent to my office,” Blake said. “Whether they are in awe of the mottling pattern on a lima bean seed, complaining about how tiny a seed is, or just saw a quadruple embryo on a corn seedling, the seed lab is a magical place where inert-seeming seeds turn into itty-bitty plants, and that never stops being amazing.”
Looking ahead, the lab is expanding its capabilities. Blake gives the example of the trait lab, which has been busy developing test protocols for non-GMO and trait presence tests using PCR technology.”
“We would love to hear from new and existing customers about which tests they are most eager to have available,” Blake said.
From tiny seeds to towering crops, it all starts in the Seed Quality Testing Lab, where precision meets passion, and every result helps plant the future.
