Welcome to T3/Wheat

This is the SANDBOX site for T3/Wheat. The Sandbox can be used to test the addition of new data to T3/Wheat. Data added to this site will be periodically cleared and reset to match the main production version of T3/Wheat. For more information on adding data to the Sandbox and submitting it to the production site, see the submitting data sections below.

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.

Future Workshops

We're collecing names and emails of those that are interested in attending future T3/Breedbase workshops on various topics such as using Android Field Book, Seedlots, Barcodes, or any other topic you may be interested in learning more about. Fill out the Virual Workshop Interest Form if you may be interested in attending a future workshop. Once we have enough interest in a particular topic, we'll reach out to everyone to schedule a date.

T3 Phenotype Data Loaded

Nov 29, 2019

2456 Phenotype trials and mean data loaded from T3.

Analyze, Selection Index

The Selection Index determines rankings of accessions based on more than one trait

Analyze, Summarize Trials

Summarize Trials shows Least squares mean values in selected Trials

Search, Loci & Genes

Search Loci & Genes allows you to search for genetic characters and associated accessions


Blank Upload Templates

Below are blank upload templates for each data type.

Sample Templates

Generate a set of sample templates for new accessions, locations, trials, and trait observations. These templates contain all new data in properly formatted templates that can be used to practice uploading each data type to the sandbox.

  1. Generate your set of sample templates
  2. Follow the Guided Phenotype Upload Workflow to upload the template for each data type

Example Templates

Below are example templates generated for demo wheat trials from a 2020 workshop. You can use these files to see how the templates are properly formatted.

For more detailed instructions, see the Detailed Phenotype Upload Instructions

Submit Phenotype Data

To submit phenotype data to T3/Wheat follow these three general steps:

Step 1: Create Upload Templates

Data submitted to T3/Wheat should be in the format of the upload template for the data type you are submitting. View the detailed upload instructions for specific information on each data type.

Step 2: Add Data to Sandbox

Once you have your upload templates, you can test-load them on this Sandbox site to check for any errors.

Step 3: Submit Trial Data

If your trial data has been successfully added to the Sandbox you can submit your trials directly to the production site by clicking the Submit Trial button on the trial detail page.

If your data has not been added to the Sandbox or if you would prefer to submit your files directly to the production site, you can submit your individual upload templates or data files to us using the Phenotype Submission Form.

Submit Genotype Data

Please Contact Us if you have genotype data you would like to submit to T3/Wheat.
