Supplementary data from: Targeted population genomics uncovers demographic history and genetic divergence in North American wild cranberry

Wild populations of North American cranberry (Vaccinium macrocarpon Aiton) are reservoirs of genetic variation that may contribute to the improvement of breeding-relevant traits. However, the extent to which wild genetic variation is geographically structured and represented in elite germplasm remains unclear. We analyzed 179 wild cranberry accessions from the upper Midwest and Eastern North America to estimate nucleotide diversity (π), population structure, and loci associated with genetic differentiation and environmental variables using a genome-informed targeted genotyping panel. Additionally, 14 demographic scenarios were evaluated using site-frequency-spectrum–based inference to identify historical events that could explain current genetic diversity. We observed extremely low nucleotide diversity within the targeted panel (π = 5x10-6). Rare allele distributions strongly influenced Ï€ and Tajima's D values, suggesting constrained diversity in the genomic regions assayed that is..., , # Supplementary data from: Targeted population genomics uncovers demographic history and genetic divergence in North American wild cranberry

## Description of the data and file structure

* Supplemental_Table_S1.csv

** Wild and breeding cranberry materials were analyzed in this study.** The wild germplasm consists of 181 accessions collected in nine U.S. states and one Canadian province, including 179 *Vaccinium macrocarpon* and two *Vaccinium oxycoccos*. The breeding panel comprises 871 *V.macrocarpon* accessions derived from controlled crosses in the Rutgers University Cranberry and Blueberry Breeding Program. Entries marked “n/a” indicate missing data.
