Figure 1. Neighbor-joining dendrogram of 72 A. hypogaea accessions from the U.S. peanut mini core revealed by using similarity coefficients based on Nei's genetic distance. The letters after each accession number refer to market types as: val, subsp. fastigiata/fastigiata/valencia; spa, subsp. fastigiata/vulgaris/spanish; vir, subsp. hypogaea/hypogaea/virginia; run, subsp hypogaea/hypogaea/runner; ???, intermediate market type. Country of origin is abbreviated as the first three letters of the country after the subspecies (for e.g., IND = India). The dashed line indicates groupings of accessions into the two major subspecies and dotted lines indicate grouping under each subspecies into market types. The numbers inside the parentheses indicate bootstrap values for groupings with >50% bootstrap support based on 1000 bootstrap samples.
