CL 15 /197 Group Name Theobroma cacao

Pound, F.J. (1938)
Cacao and Witchbroom Disease of South America with notes on other species of Theobroma. Archives of Cocoa Research 1: pp. 26-71.

Derivation: CLementina farm.
Collected by Pound.
Location: Dept. of Agriculture, Ecuador.

Notes: Progeny from Hda Clementina, Ecuador planted at Marper Farm, Trinidad in 1939-41.

Pound, 1938a [POU38A]. Selections made from material of Trinidadian origin, originally to replace a planting of "Nacional" type that had failed due to Witches' broom disease. Seven of the eight parent trees (selected by Mr. Schuldt) were of a half blanco, long oval, warty, green pod type and the eighth was a long oval smooth white base type, more than partially pigmented.

Pound, 1943b [POU43B]. Seeds were collected from the following trees: 9,10,13,15,19,22,27,78,91 and Mixed.

Bartley, 1996c [BAR96C]. The "Mixed" tree progeny mentioned above are probably those labelled CLM today.

Bartley, 1995a [BAR95A]. The CL series appear to consist of nine groups of progenies CL 9/.., CL 10/.., CL 13/.., CL 15/.., CL 19/.., CL 22/.., CL 27/.., CL 78/.. and CL 91/.. refered to by Pound (1943b) [POU43B]. There are no other CL 1/ names listed and this therefore suggests a labelling error. Some may be in error for SL.

Notes

Trinidad - CRU, University of the West Indies Datafile: DIS_PHDS - Disease reaction to Phytophthora Experimental conditions: Inoculation techinique used - spray method. Inoculum concentration: 100,000 zoospores/ml. Incubated for four days. Character Data: The following descriptions are used to segregate clones according to reaction: no visible symptoms = highly resistant to penetration, 1-5 localised lesions = resistant, 6-15 localised lesions = moderately resistant, >15 localised lesions = partially resistant/resistant to spread of lesion alone, 1-5 expanding lesions = partially resistant/resistant to penetration alone, 6-15 expanding lesions = moderately susceptible, >15 expanding lesions = susceptible, coalesced lesions = highly susceptible Disease - Phytophthora palmivora, P. megakarya (Local Names: Black Pod, Podredumbre negra, Pourriture Brune, Podridao parda).

Notes

Trinidad - CRU, University of the West Indies Datafile: TTOFATDS TTO - Fat Analysis Germplasm: Data is provided on 410 accessions. Environment: No details given. Descriptors: Data for the fat content of the shell, including standard error and the butterfat content is presented. Methods: Ripe, open pollinated pods were harvested, 2 pods from each of 5 trees (10 pods per accession) were selected. The beans were then mixed thoroughly and a sub-sample taken. The sub-sample was then cleaned to remove the mucliage, oven dried and stored at room temperature until analysis. For each accession 2 bean samples (each consisting of 20 beans) were taken from the bulked sample. The beans were shelled and eaach sample was groung using a coffee grinder (2x30 seconds). The ground samples were then dried for 16 hours at 110 degrees C, cooled and stored in a dessicator at 25 degrees C until analysis. From the cried ground samples, a 2 gram sub-sample was weighed into a beaker, 100 ml of 4.0M HCl was added and the sample boiled for 30 minutes. The boiled sample was filtered and the residue washed with distilled water until clear of pigment. After washing, the filtered sample was placed in an extraction thimble and dried for 16 hours at 60 degrees C. The butterfat from the bean samples was extracted using the Soxtec System (Tecetor). Each dried sample was extracted for one hour using petroleum ether (40-60) as the solvent. The butterfat extracted from the sample was then dried in an oven for 30 minutes at 100 degrees C, cooled in a dessicator and the percentage butterfat determined on a dry matter basis.
