 Vello, F., Garcia, J.R. & Magalhaes, W.S. (1974)
Producao e selecao de cacaueiros hibridos na Bahia. Proceedings of the 4th International Cocoa Conference, 1972, St. Augustine, Trinidad. Cocoa Research Unit, Trinidad. pp. 38-56.

Derivation: Selecao Instituto do Cacau.
Location: Bahia, Brazil.

Habit - prolific and vigorous. Fruit - thin husks. Seeds -small.

Notes:  Vello et al., 1974a [VEL74A]. Clones with numbers less than 100 are from selections made from the area around the Experimental Station at Urucuca. Clones with numbers between 100 and 800 are the progeny from these clones and clones with numbers greater than 800 are selections from a CATONGO population at the same experimental station.

Bartley, 1995a [BAR95A]. Types include Para, Comum, Catongo and Maranhao. Possibly originally from Brazilian-Venezuelan border.

Bartley, 1998a [BAR98A] The clones in this series are constituted in the following way. Numbers 1-28 are selections made on the farm which was later developed into the Urucuca research station. Numbers 28-800 are open pollinated seedlings of the previous selections. They are random selections made without any discrimination. The rows of progeny were consecutively numbered in order of planting but unfortunately no records were kept of the original planting or of the parentage of each progeny. Numbers above 800 are seedling progenies of CATONGO. All basic characters of these plants should be the same so all of these must have white seeds if they are correctly identified.
