Additional file 3: Figure S1 A) Principal Coordinate Analysis of SSR diversity for 89 highbush accessions. Colors represented sub-populations identified at K = 3. Green: ‘Weymouth’ sub-population; Red: NHB sub-population; Blue: SHB subpopulation; B) The optimal number of sub-populations (K = 3) for 89 highbush accessions. K = 3 was determined using delta K method.
