Overview of the major collections of T. grandiflorum (cupuaçu) and its closest wild relative, T. subincanum (cupuí), in the Amazon Basin (Supplementary Methods, Supplementary Fig. 1, and Supplementary Data 1). Cupuí is characterized by smaller fruits, typically measuring 7–15 cm in length and 5–8 cm in width, with reddish-purpureus structures in the flowers. In contrast, cupuaçu produces larger fruits, ranging from 10–25 cm (or even larger) in size, accompanied by yellowish-green flower structures. The pulp of cupuaçu fruits is highly valued and widely used in the preparation of a variety of desserts. The collections were conducted at multiple location sites, including Xapuri-Acre (ACRE), Balbina-Amazonas (BALB), Tapajós-Pará (PARA), and São Gabriel da Cachoeira-Amazonas (SGCA).
