WheatQTLdb V2.0: a supplement to the database for wheat QTL

We recently developed a database for hexaploid wheat QTL (WheatQTLdb; ), which included 11,552 QTL affecting various traits of economic importance. However, that database did not include valuable QTL from other wheat species and/or progenitors of hexaploid wheat. Therefore, an updated and improved version of wheat QTL database (WheatQTLdb V2.0) was developed, which now includes information on hexaploid wheat (Triticum aestivum) and the following seven other related species: T. durum, T. turgidum, T. dicoccoides, T. dicoccum, T. monococcum, T. boeoticum, and Aegilops tauschii. WheatQTLdb V2.0 includes a much-improved list of QTL, including 27,518 main effect QTL, 202 epistatic QTL, and 1321 metaQTL. This newly released WheatQTLdb V2.0 also has additional valuable options to search and choose the QTL, category-wise, and trait-wise data for their use in research or breeding programs.

Automated summary

We have developed an updated and improved version of the wheat QTL database (WheatQTLdb V2.0) that includes information on hexaploid wheat and other related species. The database provides an improved list of QTL and additional options for searching and selecting QTL, making it valuable for research and breeding programs.
