Homero Castro Zurita and the Tree Called CCN-51
Men and Women of Cacao · History of Cacao
Some of the most consequential decisions in cacao history happen before a bean reaches a workshop. They happen when a grower chooses a tree.
In Ecuador, the selection associated with Homero Castro Zurita acquired a name that now travels through farming manuals, research papers and chocolate debates: CCN-51.
A breeding story in Naranjal
Castro developed the material at his farm in the Naranjal region of Ecuador's Guayas province. The name refers to Colección Castro Naranjal, with 51 identifying the selected material. Ecuadorian historical accounts place its development in the 1960s. [1, 2]

The agricultural problem was serious. Disease and unreliable production could make a cacao planting an uncertain investment. Breeding offered a way to search among combinations of inherited traits for trees that performed usefully in the field.
Why growers paid attention
A 2022 review by Ramon E. Jaimez and colleagues describes CCN-51's productivity, adaptability and expansion across producing regions in Ecuador, Colombia, Brazil and Peru. The review also examines its genetics, physiology and sensory characteristics. [1]
Those categories belong together. A farmer encounters a tree through its growth, harvest and response to local conditions. A chocolate maker encounters the results through beans whose flavor also depends on fermentation, drying and manufacture. The same material therefore raises several different questions.

The meaning of a successful selection
Selecting and propagating useful material can carry a breeder's decision far beyond the original farm. A clone allows a particular genetic selection to be multiplied. Its wider adoption then depends on nurseries, growers, markets and the conditions in which it is planted.
CCN-51's history makes the scale of that chain visible. A selection linked to one Ecuadorian farm became part of planting choices elsewhere in Latin America. [1, 2]
A tree does not answer every question
The research review treats flavor enhancement and further improvement as continuing challenges. High production does not settle every question of quality; a chocolate's performance cannot be predicted from a cultivar name alone. [1]
Castro's lasting contribution lies in changing the material available to farmers and breeders. The wider history includes the decisions people made with it: where to plant it, how to handle its harvest and what other cacao diversity to maintain alongside it.
His story brings cacao history back to a living plant. Before a factory can transform chocolate's texture, someone has already made a decision about the tree that will supply it.
