Data from: A Community Resource for Exploring and Utilizing Genetic Diversity in the USDA Pea Single Plant Plus Collection

Included in this dataset are SNP and fasta data for the Pea Single Plant Plus Collection (PSPPC) and the PSPPC augmented with 25 P. fulvum accessions.

These 6 datasets can be roughly divided into two groups. Group 1 consists of three datasets labeled PSPPC which refer to SNP data pertaining to the USDA Pea Single Plant Plus Collection. Group 2 consists of three datasets labeled PSPPC + P. fulvum which refer to SNP data pertaining to the USDA PSPPC with 25 accessions of Pisum fulvum added. SNPs for each of these groups were called independently; therefore SNP names that are shared between the PSPPC and PSPPC + P. fulvum groups should NOT be assumed to refer to the same locus.

For analysis, SNP data is available in two widely used formats: hapmap and vcf. These formats can be successfully loaded into TASSEL v. 5.2.25 (http://www.maizegenetics.net/tassel). Explanations of fields (columns) in the VCF files are contained within commented (##) rows at the top of the file.

Descriptions of the first 11 columns in the hapmap file are as follows:

rs#- Name of locus (i.e. SNP name)
alleles- Indicates the SNPs for each allele at the locus
chrom- Irrelevant for these datasets, since markers are unordered.
pos- Irrelevant for these datasets, since markers are unordered.
strand- Irrelevant for these datasets, since markers are unordered
assembly#- required field for hapmap format. NA for these datasets
center- required field for hapmap format. NA for these datasets
protLSID- required field for hapmap format. NA for these datasets
assayLSID- required field for hapmap format. NA for these datasets
panel- required field for hapmap format. NA for these datasets
QCcode- required field for hapmap format. NA for these datasets

The fasta sequences containing the SNPs are also available for such downstream applications as development of primers for platform-specific markers.

Resource Description: These data are for the Pea Single Plant Plus Collection (PSPPC) and the PSPPC augmented with 25 P. fulvum accessions.

The 6 datasets can be divided into two groups. Group 1 consists of 3 datasets labeled “PSPPC” which refer to SNP data pertaining to the USDA Pea Single Plant Plus Collection. Group 2 consists of 3 datasets labeled “PSPPC + P. fulvum” which refer to SNP data pertaining to the PSPPC with 25 accessions of Pisum fulvum added. SNPs for each of these groups were called independently; therefore any SNP name that is shared between the PSPPC and PSPPC + P. fulvum groups should NOT be assumed to refer to the same locus.

For analysis, SNP data is available in two widely used formats: hapmap and vcf. These files were successfully loaded into the standalone version of TASSEL v. 5.2.25 (http://www.maizegenetics.net/tassel).

Explanations of fields (columns) in the VCF files are contained within commented (##) rows at the top of the file.

The first 11 columns required for the hapmap format are as follows:
rs#- Name of locus (i.e. SNP name)
alleles- Indicates the SNPs for each allele at the locus
chrom- N/A, since markers are unordered.
pos- N/A, since markers are unordered.
strand- N/A, since markers are unordered
assembly#- N/A
center- N/A
protLSID- N/A
assayLSID- N/A
panel- N/A
QCcode- N/A

The fasta sequences containing the SNPs are also available here for such downstream applications as development of primers for platform-specific markers.
