Replication Data for: Extensive simple sequence repeat genotyping of potato landraces supports a major reevaluation of their gene pool structure and classification uri icon


  • total of 742 potato landraces of all cultivated potato species were examined: S. tuberosum subsp. andigenum, putatively tetraploid (251 accessions); S. ajanhuiri, diploid (22); S. chaucha, triploid (151 accessions); S. tuberosum subsp. tuberosum, tetraploid (27 accessions); S. curtilobum, pentaploid (21 accessions); S. juzepczukii, triploid (35 accessions); S. phureja, diploid (104 accessions); S. stenotomum, diploid (131 accessions); 7 diploid wild species accessions in the northern S. brevicaule complex S. ambosinum Ochoa (1 accession), S. bukasovii Juz. (4 accessions), and S. multiinterruptum Bitter (2 accessions); and the wild tetraploid species S. acaule Bitter (1 accession) (750 accessions in total with the 8 wild species). Selection of these wild species is based on recent amplified fragment length polymorphism (AFLP) studies that documented the northern S. brevicaule complex wild species to be the progenitors of the cultivated potatoes and S. acaule believed to be a wild species parent in the hybrid species S. juzepczukii and S. curtilobum. We qualify landrace collection ploidy as ‘‘putative’’ because only S. phureja has been counted in detail (19), that showed extensive examples of incorrect assumptions of ploidy as discussed above. Data of these accessions includes the accession number, taxonomic identification, ploidy (when known), locality of collection, and average number of SSR alleles per accession
