SPA 17 [COL]    Theobroma cacao

 Colombia - ICA Palmira (1989)
? A catalogue of the cacao germplasm at ICA Palmira. F. Ocampo Rojas, ICA Palmira, Colombia.

Derivation: Seleccion PAlmira.
Collected by Pound.
Location: Palmira, Colombia.

As these are all progeny from a single fruit they should all have basically then same characteristics. Bartley, 1995a [BAR95A]. Leaf - some unpigmented, large, broad and have an undulating (puckered/crinkled) surface. Fruit - basically similar in shape being broad elongate with slight roughness. Seed - some white. Bartley, 1997a [BAR97A]. Variation seen in flush leaf pigmentation from light green (white); the pigmentation of the stamen, which is often intense; and the colour of the fruit, which is either light green or dark green with a tendancy to be shiny.

Notes:  Lockwood & Gyamfi, 1979, [LOC79A] Collections made in Colombia by Pound, somewhere in the Amazon valley. Very similar to some Ecuador Oriente types.

Progeny of a fruit donated to Colombia by Pound (1943?).

Bartley, 1995a [BAR95A]. The association between unpigmented flush leaves and white cotyledons found in some of these clones is typical of the genotypes from the Napo river. Pound did visit Santa Clotilde, the Peruvian research station on this river and the material may therefore have originated in this region.

In previous versions of the ICGD the SPA [COL] clones were included as synonyms of the group SC [COL] (SC 57 - 76 inclusive). The synonymy has now been reversed as this material was originally described as SPA and is more widely known under this name, as advised by Dr. Bartley.
