The potato genetic identity kit is made of 24 informative SSR markers useful for genotyping potato landraces. These markers were selected based on quality criteria,
genome coverage, and locus-specific information content. We selected two SSR markers per chromosome with
a linkage distance of at least 10 cM and with a high polymorphic information content (PIC) value.
The new potato genetic identity kit will be of particular utility to standardize the choice and allele sizing of
microsatellites in potato and aid in collaborative projects by allowing cumulative analysis of independently generated data.
