Sample Collection Guidelines

Variety identification by DNA markers

1.       Select a healthy plant to be identified as a variety.

2.       Collect a leaf.  If leaf is not available, collect stem or root. We only need a small sample. Place sample in a zip lock bag.  Use cooler if collecting several samples to avoid heat exposure.

3.       If we do not have your varieties already in the database, include a sample of each variety that you wish to compare your sample with.

4.       Fill out sample submission form and use as a packing slip.

5.       Ship by express mail. Samples collected on Friday can be stored in refrigerator and shipped on Monday
