Development of a single-nucleotide-polymorphism marker for specific authentication of Korean ginseng (Panax ginseng Meyer) new cultivar “G-1”

The results from our study shows that this SNP-based approach to identify the G-1 cultivar will be a good way to distinguish accurately the G-1 cultivar and P. quinquefolius from other Korean ginseng cultivars using a SNP at 45S ribosomal DNA region.
