Seed samples
- Seed Health Tests                [Back toTop]
1. Draw a representative samples (For large lots, multiple samples may be tested).
2. The seeds preferably should be untreated.
3. Quantity of seeds should be enough for the tests requested. (we can advise you if same seeds can be used for multiple tests). For bacterial fruit blotch grow     out, 10% extra seeds should be supplied to account for low germination.
4. Seeds should be securely packed and labeled accordingly.
5. Prepare a packing slip (you can fill our Sample Submission Form to serve as a packing slip. Please completely fill the form).
6. Ship by express mail.
7. International customers should include Phytosanitary Certificate. Alternatively, you can use our Red/White labels to ship to USDA and USDA will forward samples to us. Ask us for Red/White labels.

- Hybrid Purity Tests               [Back toTop]
A minimum of 96 seeds is a suggested sample size. For hybrids that are submitted for the first time, we will need a sample of male and female inbred of that hybrid. If you are uncomfortable to provide the inbreds, you can provide crushed seeds or leaf tissue of the inbreds and we will be able to extract high quality DNA.
1. Ship 200 seeds from a lot.
2. Include parent inbreds if submitting a hybrid for the first time.
3. Fill out Sample Submission Form and use this as a packing slip.
4. Ship by express mail.
5. International customers should include Phytosanitary Certificate. Alternatively, you can use our Red/White labels to ship to USDA and USDA will forward samples to us. Ask us for Red/White labels.

- Variety Identification Tests from Seeds               [Back toTop]
We are assuming that hybrid/variety is pure and there is no variability from seed to seed. Therefore, we will run only 2 seeds (or 2 pools of seeds) to keep cost down. We will compare DNA fingerprint of the sample with your varieties in our database. If you are submitting for the first time, we will need a reference that we can compare with.
1. Ship 20 seeds from a lot. Coin envelops may be used.
2. Fill out Sample Submission Form and use this as a packing slip.
3. Ship by express mail.
4. International customers should include Phytosanitary Certificate. Alternatively, you can use our Red/White labels to ship to USDA and USDA will forward samples to us. Ask us for Red/White labels.

4. Fill out Sample Submission Form and use as a packing slip.
