Figure 1

(a) Relationships among Persian walnut populations samples as represented by principal component analysis (PCA) using 33,336 genome-wide SNPs profiles (PRO_ID: different provinces of Iran); (b) Geographical distribution of the studied walnut samples across Iran; and (c) Admixture proportions of 95 Iranian walnut accessions as assigned using fastSTRUCTURE and the admixture option for K = 2 to K = 5. Each vertical bar exemplifies a sample (95 Iranian walnut genotypes sampled in eight provinces of Iran).
