Release 6
(Jan. 08, 2008)
This Chicken Quantitative Trait Loci database (ChickenQTLdb) has gathered all Chicken QTL data published during the past 10+ years. The database and its peripheral tools make it possible to compare, confirm and locate on chicken chromosomes the most feasible location for genes responsible for quantitative trait important to chicken production.

The current release of the chickenQTLdb contains 657 QTLs from 45 publications. Those QTLs represent 112 different traits (see data summary for more recent updates). These data have also been submitted to the NCBI Gene and Map Viewer resources, where the information about markers are matched to marker records in NCBI's UniSTS database. For ChickenQTLdb development and releases history, see this supplementary note.

Information in the ChickenQTLdb can be accessed in the following ways:
  1. Search
    By chromosomes, animal trait names and/or key-words in the publication).

  2. Browse
    By chromosome numbers or animal trait ontology tree.

  3. View Maps
    A whole genome map and individual chromosomal maps are available.

  4. Data Summary
    QTL data statistics by chromosomes, traits, trait types and publication year.
