*3.3. Genetic Diversity*

The pattern of PCoA (Figure 3) showed that the first two axes accounted for 30.19% and 6.91%, respectively, of the total variation and the 384 peanut accessions were divided into three broad groups across the first two axes. The first axes separated the South Korean (clustered filled diamonds) and South American (green filled squares) peanut accessions into two very different parts, and, at the same time, assigned East Asian, South Asian, and West Asian peanut accessions (brown filled triangles, pink filled diamonds, and green filled circles, respectively) to another part. Additionally, the peanut accessions that originated from East Africa, South Africa, West Africa, North America, and Europe formed two concentrated groups by the first and second axes. Interestingly, the accessions from South Korea were genetically very different from those from South America, which is the origin of the cultivated peanut.
