Search terms can be entered at the level of trait category, trait subcategory or trait description.
For example, to search for QTL associated with grain weight users can either enter the search term “Grain weight” in Trait Description, or select the trait category “Panicle” or Trait subcategory “Grain & Panicle Yield”, and search in the Trait Description options to select grain weight related traits.

Select from the drop down menu to select one or more target chromosomes

Users can specify a target set of coordinates, e.g.
Physical location IS WITHIN 500000bp of 6,000,000 or
Physical location IS BETWEEN 5,500,000 AND 6,500,000

This can be done based on the physical coordinates of the most recent version of the sorghum genome assembly (v.3), or using the cM coordinates of the sorghum consensus map (Mace et al 2009).
