Replication data for: The single Andigenum origin of Neo-Tuberosum potato materials is not supported by microsatellite and plastid marker analyses

Simple sequence repeat alleles were detected and scored using the SAGA Generation 2 software (LI-COR, USA). The SSR alleles were identiWed by their size in base pairs of the upper band of the allele and scored as present (1), absent (0), or missing (9). Missing data were less than 5% (3.8%) which is acceptable for cluster analysis.

The 241 bp plastid deletion marker was analyzed for all 688 landrace accessions by using the PCR primers and protocols from Hosaka (2002). PCR products were separated by electrophoresis on a 1% agarose gel, and Lambda phage digested by PstI was used as a molecular weight marker. The 241 bp deletion polymorphism was determined for size in base pairs and scored as “T” (with the deletion) or “X” (lacking it) based on clearly separating bands.
