Developed by Cornell, US-Grown Zero THC Hemp Planting Seed for Hemp Fiber Farmers
Is Cornell's US-grown fiber seed a zero THC hemp planting seed?+
Cornell's US-grown fiber seed is Ursa Alta, not a variety named zero THC. Some NC State plots were nondetectable for total THC. Cornell Chronicle reports about 0.02% THC. Fiber farmers still sample the crop under USDA hemp rules.
Searchers asking for zero THC hemp planting seed usually want a fiber crop that will not fail a THC test. Cornell did not release a fiber cultivar under the name zero THC. The US-grown planting seed Cornell licensed for fiber farmers is Ursa Alta. Breeders at Cornell AgriTech removed THC-producing genes with molecular markers. Cornell Chronicle then reported that the finished cultivar consistently tests at about 0.02% THC.
That number is the honest label. About 0.02% is low. It is not 0.00%. It is also far under the 0.3% total THC limit in the USDA AMS hemp rules. Industrial hemp is not marijuana. A nondetectable lab row and a 0.02% breeding result can both describe the same seed, because labs report "ND" when the reading falls below their detection limit.
NC State Extension is the field record. Ursa Alta total THC was nondetectable at Kinston in 2023 and at Goldsboro in 2024, and 0.04% at Kinston in 2024. Use those rows. Do not round them to zero on a contract.
What Zero THC Hemp Planting Seed Means on a Fiber Farm
The phrase zero THC hemp planting seed is a search, not a seed class USDA recognizes. The legal line is 0.3% total THC on a dry-weight basis. A lot at 0.02% and a lot the lab could not detect are both hemp if the official sample passes. A lot over 0.3% is not saved by a variety story.
On the AOSCA hemp index, a variety is literally named Zero THC. It is SOTE757.Z.1 from OATS Global Group, not a Cornell release. Ordering "zero THC" without the variety name is how a fiber farmer plants the wrong genetics. Cornell's fiber name is Ursa Alta, experimental designation GVA-H-22-1061.
Condor Seeds in Yuma, Arizona holds the commercial license and, as of Cornell's May 2026 account, is selling that seed. The seed field in the Chronicle photo is in Arizona. Development was at Cornell. Both facts can be true. The bag you want says Ursa Alta.
How Trial Rows for Zero THC Hemp Planting Seed Should Be Read
Read the year and the site before you repeat a number. One nondetectable row is a result. Cornell's 0.02% figure and NC State's 0.04% Kinston row are also results. Zero THC hemp planting seed, as a phrase, has to survive that spread. A fiber farmer who quotes only the nondetectable row and skips the 0.04% row is writing a claim the trial did not make.
Kinston and Goldsboro on Zero THC Hemp Planting Seed
In 2023 at Kinston, Ursa Alta was harvested September 21 for fiber, with nondetectable total THC, 9,820 lb/ac of straw, and 1,853 lb/ac of bast. In 2024 the same name was 0.04% at Kinston and nondetectable at Goldsboro, where straw reached 8,643 lb/ac after a hard season. The low THC fiber guide carries the yield and latitude detail. This page is only the THC label.
Why Breeders Can Still Say the Genes Are Gone
AOSCA's description of Ursa Alta says Cornell used marker-assisted selection against CBDA synthase genes tied to THC production, starting from a high-THC Chinese landrace. Smart's lab screens seedlings and discards the ones that still carry those genes. That is why the cultivar holds near the bottom of the legal range. It does not make every future field test print "0.00" on your state's form.
Sampling Still Sits on Top of Zero THC Hemp Planting Seed
Your state samples the crop you grew, not the Cornell trial. Heat, fertility, and stress can move cannabinoids. Keep the seed tag, the certificate of analysis on the lot, and the compliance sample. If a buyer wants "zero" in a purchase order, write the number you can defend, which is the lot result, and point them at 0.02% rather than a slogan.
What to Order Instead of Zero THC Hemp Planting Seed
The search says zero THC hemp planting seed. The bag should say Ursa Alta. Order that fiber cultivar and run the acre as fiber: mow, ret, and bale for a buyer who asked for stalk, not grain. Spring planting and a named offtake partner come before the drill. If the tag uses the word zero but names a different variety, it is not Cornell's fiber release.
Buy the Named Lot, Not the Adjective
Certified seed should show Ursa Alta and a lot number. Ask whether the bag is breeder, foundation, registered, or certified class. Sell the crop only after the offtake partner has approved that variety. HFGA makes that introduction at no charge. The partner still sets the spec.
Keep Zero THC Hemp Planting Seed Off the Grain Contract
Ursa Alta is not viable for grain north of 32°N, because frost arrives before seed matures. A fiber farmer who also wants food grain needs a different Cornell cultivar. That comparison is the grain zero-THC note. Mixing the two names on one acre produces a crop neither buyer ordered.
Write the Number the Mill Can Audit
Textile and hurd buyers pay for stalk quality, moisture, and a passing THC sample. They do not pay extra because a headline said zero. Commodity pricing is the board you compare with the fiber bid. The FAQ covers the marijuana question neighbors will ask. Trust is the lot certificate. Education is ND versus 0.02% versus 0.3%. Profit is a fiber acre that passes the sample you were always going to take.
FAQ
Quick answers from this article.
What did NC State report for Ursa Alta total THC in 2023?+
At Kinston in 2023, NC State reported Ursa Alta total THC as nondetectable. Nondetectable means below that lab's limit on that sample, not a promise of absolute zero.
What total THC did Ursa Alta show at Kinston in 2024?+
NC State reported 0.04% total THC for Ursa Alta at Kinston in 2024, and nondetectable at Goldsboro the same year. Both sit under the 0.3% hemp line.
Is the AOSCA variety named Zero THC a Cornell release?+
No. On the AOSCA hemp index, the variety named Zero THC is SOTE757.Z.1 from OATS Global Group. Cornell's fiber release is Ursa Alta.
Do nondetectable trial results replace state THC sampling?+
No. A nondetectable row in a university trial does not waive the pre-harvest sample your state requires. Keep the lot certificate and the field result.
Which Cornell seed should a fiber farmer order for stalk yield?+
Order Ursa Alta for a dedicated fiber acre. It is the Cornell cultivar released for fiber, US-grown for sale in Arizona, and the wrong seed for a northern grain contract.
