All locus types (points, probes, QTL, etc) may be accessed from this center. The QTL at MaizeGDB are a subset of data available to about year 2003; each QTL has an assigned bin (about 10-20 cM resolution), or a bin range and may also be found on the bin viewer. Recently we have begun to integrate published trait values data for germplasm with public genotype data. See also the Diversity Center.
Simple Locus/QTL Search:
This search form allows you to just enter a name or partial name to quickly retrieve the desired loci or QTL. If no Locus matches are found, this search will attempt to find QTL Experiment and Trait matches. The latter searches can be queried separately below.

Simple QTL Experiment Search:
The form below allows you to search quickly through our QTL data for particular QTL experiments. If you'd just like to see a list of these experiments, enter just the wild card character % into the search field.
The above example search lets you find all experiments conducted by Bill Beavis. Other interesting searches include Abler 1991 (shows the series of six Abler QTL experiments from 1991) or Veldbloom (a pair of highly-cited QTL experiments).
This search can be executed from any page on the site by selecting QTL Experiments from the pull-down menu in the upper right and entering your search terms in the field.
Simple Trait Search:
The form below allows you to search quickly through our trait data for particular traits. If you'd just like to see a list of all traits, put just the wild card character % into the search field.
The above example search lets you find all traits related to kernel weight. Other interesting searches include abscisic acid and ATP.
This search can be executed from any page on the site by selecting Traits from the pull-down menu in the upper right and entering your search terms in the field.
