Data Extent

T3 Barley

The Triticeae Toolbox Barley (T3 Barley) is an extension of The Hordeum Toolbox (THT), which was created by the preceding Barley CAP. T3 Barley incorporates all of the THT data.

The Triticeae Toolbox (T3) is the web portal for data generated by the Triticeae Coordinated Agricultural Project (T-CAP), funded by the National Institute for Food and Agriculture (NIFA) of the United States Department of Agriculture (USDA). It also contains data from US Uniform Regional Nurseries, supported by the US Wheat and Barley Scab Initiative. The database was initially developed as The Hordeum Toolbox (THT) to hold barley data generated by the Barley CAP project (2006-2010). T3 Barley hods data generated for Hordeum vulgare L. T3 Wheat holds data generated for Triticum spp. T3 Oat holds data generated for Avena. All are being enhanced in database performance, community curation and user tools. T3 contains germplasm line information, pedigree, genotype and phenotypic data from breeding programs participating in the CAP and core germplasm collections maintained by the USDA National Small Grains Collection.
