• Q martrix showing population structure data for the maize associaton mapping panel. Population structure was estimated using SSRs and the STRUCTURE algorithm. An Excel file with pedigree information is available [download], as is a text file readable by TASSEL software [download]. The following paper has more details about these estimates of population structure:

  Association panel genotypes at a set of 13 SSR markers (useful for quality control purposes) are available here.

We provide a zip archive containing files needed for QTL mapping of your own traits in our maize Nested Association Mapping population. Please be sure to read the text file Disclaimer_and_File_Descrips_20080703.txt first; this file is included in the archive, and includes descriptions of the contents of each file as well as the following disclaimer:

DISCLAIMER:  NAM_map_20080419.xls is a preliminary map for the phenotypers of NAM. We are still correcting map errors as the maize physical map improves and errors are found in the map order and calling; however, this map is accurate enough to be useful for basic QTL mapping. Our group is currently working on two papers describing this data set: One on mapping flowering time and one on recombination and segregation distortion. Please check back monthly for updates.
