- Preliminary Genotyping by Sequencing (GBS) genotypes for NAM, the Maize282 association mapping population, and our teosinte/W22 BC2S3 population. By downloading these data you are agreeing to our data release conditions which can be read here (the file 'GBSGenosDataReleaseConditions.txt' is also included in each zip download). As we further refine our GBS bioinformatics pipeline, we will post new releases of these genotypes. Check here frequently for updated data. (NAM & 282 current version: 20111123; Posted: 20111221)

- 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

Second generation HapMap SNPs (Maize HapMapV2)
The maize HapMapV2 study is a collaborative effort involving Panzea, CSHL, BGI, CAU, UC Davis, USDOE and several others. This study generated random-sheared, paired-end Illumina GAII reads from 103 maize, teosinte and maize landrace inbred lines at a depth ranging from 4-30X. High quality genotypes were obtained for 50 million SNPs and small indels. Two whole-genome analysis manuscripts from this work are currently in review. Under the conditions specified here, we are allowing prepublication access to the resulting genotypes for a subset of the lines: the maize NAM parents and the teosinte inbred lines. Underlying raw sequence reads are also available for small sets of lines of interest to you. If you are interested in obtaining these data, or a subset thereof, please email Jeff Glaubitz at jcg233@cornell.edu. In your email, please state the purpose for which you will use the data.
