Genetic admixture analysis of the Sarraméa population (New Caledonia). Ternary plot of individual ancestry computed on the Sarraméa population (367 individuals) by structure with K = 3 and 12 microsatellite loci. Sample plotting at the apices have a proportion of membership close to qi = 1.0, that is, to pure species: Coffea canephora (green points), C. liberica (blue lozenges), and C. arabica (pink triangles). Hybrids and admixed individuals with at least 15% membership to a second species (yellow squares) are labeled with individual names and mother species chloroplastic origins are in brackets (C. canephora: [Can]; C. liberica: [Lib]; and C. arabica: [Ara]).
