Rosaceae Trait Ontology

GDR has made an effort to standardize the trait names and the abbreviations for all the trait data entered in the database.  GDR QTL are associated with these trait terms and QTL labels, assigned by GDR, use the below abbreviations for the listed traits.  Each of these trait terms is either an existing term or a child term of the existing term of the plant trait ontology. One trait term can belong to multiple Root TO term. The trait term can be used to describe any Rosaceae crops and the 'crop associated' column shows some example crops that have QTL for the term. When possible, we have used abbreviations that are consistent with established trait or crop ontologies. Where new ones were developed they have been submitted to the Trait Ontology consortium for inclusion. We would appreciate if new studies could use these standardized terms where possible. If you have a new trait or are unsure about the naming please contact us.
