Integrating Genetics and Genomics to Advance Soybean Research

This page shows all of the QTL Classes (green links) in SoyBase. The 'New' tag is used to indicate when QTL have recently been added to that QTL Class. This allows users to quickly see if new QTL's have been added to their favorite trait.

Underneath each QTL class name (green links), is the soybean trait ontology term (black text) associated with the QTL.

Clicking on a QTL Class opens a page listing all of the individual QTL's in that Class. The 'View in Whole Genome' button (upper right of the page) allows the user to see all of the individual QTL's of a class and their relative position on the 20 soybean linkage groups. Newly reported QTL are indicated in both the chromosomal and table views.

To view the QTL sorted by their associated soybean trait, click the "View by Trait" link below.
