Welcome to the New T3/Oat

T3/Oat is the repository of oat phenotype and genotype data for the Global Oat Genetics Database, a project initiated in January 2014 by the following investigators. For more information see the Oat Global website.

• Gabe Gusmini (PepsiCo), • Joe Lutz (General Mills), • Bruce Roskens (Grain Millers), • Nicholas Tinker (AAFC), • Kay Simmons, Jack Okamuro, Jose Costa, Jean-Luc Jannink, and Gerard Lazo (USDA-ARS)

  Leave Feedback

The New T3/Oat is the next evolution of The Triticeae Toolbox (T3). We are in the process of transitioning all of T3's data and tools to this new system. We encourage you to leave feedback about feature improvements, missing tools, and/or any ideas you may have to improve the site.

Submit Phenotype Data

Phenotype data can be submitted to T3/Oat in two ways:

Using the Sandbox

When using the sandbox, you create upload templates that contain the trial information. Then, you upload those templates to the Sandbox to check for any errors. When the trial has been successfully added you can use the Submit Trial function to submit the trial directly to us for inclusion in the production site. Visit the T3/Oat Sandbox for more information.

Submitting files directly to us

If you have upload templates that you think are properly formatted or data files that are not formatted as upload templates, you can submit the files directly to use for inclusion in the production site by submitting them to us through the Phenotype Submission Form.
