Population genomic analysis of 558 accessions of faba bean germplasm. a Geographical distribution of 558 accessions of faba bean germplasm. Provincial capital coordinates were applied for samples from the same province in China, whereas capital coordinates were used for samples from other countries. b Phylogenetic analysis and ADMIXTURE analysis at K = 2 and 3. c PCA. d Population genetic diversity and genetic differentiation between three genetic groups of faba beans. e LD decay analysis of three genetic groups. Green, pink, and blue represent group 1, group 2, and group 3, respectively
