Dataset for: Potato genotyping using Infinium Potato Array SNPs.

103 tetraploid breeding clones were genotyped using the SolCAP Infinium Potato SNP Platform containing 8300 SNP. The objectives of the study were to examine in this set of germplasm: (i) the genetic substructuring and (ii) the association of SNP markers with late bligh resistance phenotype. The DNA of the germplasm was extracted at 2012 at CIP and submitted for genotyping to Michigan State University on a service contract. The normalized allele signal ratio (normalized X divided by the sum of normalized X and normalized Y) was calculated using Illumina GenomeStudio software and exported in csv format. A custom R script was used to call and filter the genotypes. Each SNP was run through the CodomMarker function of the fitTetra R package. Each sample was categorized into one of five possible tetraploid genotypes (AAAA, AAAB, AABB, ABBB, or BBBB). Markers were filtered allowing for at maximum 5% missingness.
