Welcome to T3/Wheat

T3 is a repository for public wheat data generated by the Wheat Coordinated Agricultural Project (Wheat CAP). It also contains data from the US Uniform Regional Scab Nurseries, supported by the US Wheat and Barley Scab Initiative (USWBSI). Funding is provided by the National Institute for Food and Agriculture (NIFA) and the United States Department of Agriculture (USDA). The current project is funded through NIFA's International Wheat Yield Partnership (IWYP) and part of the Agriculture and Food Research Initiative (AFRI). The database was developed at triticeaetoolbox.org/wheat. That website was archived in Jan 2020 and all the data was moved to this current site.

Submit Phenotype Data

Phenotype data can be submitted to T3/Wheat 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/Wheat 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.
