Table 1. Geographic populations* and genetic classification of the analyzed Theobroma cacao trees.

For populations 1–5 (from farms in Soconusco, Mexico) genetic clustering was based on membership to the Criollo group (%) described by Vázquez-Ovando et al. (2014) using SSR markers. For the reference trees** (populations 6–9), the genetic grouping was suggested by Avendaño-Arrazate et al. (2010) and the database accessions (ICGD; Turnbull & Hadley, 2016).
