High-resolution genetic map and SNP chip for molecular breeding in <i>Panax ginseng,</i> a tetraploid medicinal plant.

ABSTRACT: Ginseng (Panax ginseng) renowned as the king of medicinal plants. Ginseng grows slowly under shade conditions, requiring at least 4 years to produce a limited number of seeds. Molecular breeding of ginseng faces challenges due to its the tetraploid genome and the absence of an efficient molecular marker system. To overcome these obstacles, we adopted genotyping-by-sequencing to delve into genetic mapping and survey genetic diversity. We constructed a comprehensive genetic map comprising 24 linkage groups, each corresponding to one of the 24 chromosomes in the ginseng genome, based on 1216 nonredundant SNPs obtained from an F ₂ mapping population. Additionally, 431 103 SNPs were identified from 119 diverse ginseng genotypes. From these, 192 informative subgenome-spe
