Fig. 1From: Diversity and population structure of Nordic potato cultivars and breeding clonesGenetic diversity revealed by a principal component analysis (PCoA) based on Nei’s genetic distance of single nucleotide polymorphism (SNP) markers among the 133 accessions. Groupings are based on (A) population and country of origin for NordGen genotypes, (B) population and cycle of selection (T3 – T6 +) for SLU breeding clones, and (C) clonal typeBack to article page
