Abstract Key message Twelve potato accessions were selected to represent two principal views on taxonomy. The genomes sequenced and analyzed for structural variation (copy number variation) against three published genomes. common ( Solanum tuberosum L.) is an important staple crop with a highly heterozygous complex tetraploid genome. other taxa of cultivated contain varying ploidy levels (2 X –5 ), variations are in the these species, likely contributing diversification or agronomic traits during domestication. Increased understanding genomic will aid exploration novel traits. Thus, sequencing data from twelve landraces, representing four levels, used identify compared currently available reference genomes, double monoploid genome diploid inbred clone S. chacoense . results copy analysis showed that majority while deletions greater than duplications, duplicated genes deleted ones. Specific regions have high density CNV events. Further, auxin-induced SAUR (involved abiotic stress), disease resistance 2-oxoglutarate/Fe(II)-dependent oxygenase superfamily proteins, among others, had increased numbers relative references.
