The CRIG cocoa germplasm collection with notes on codes used in the breeding programme at Tafo and elsewhere. Technical Bulletin, No. 10, Cocoa Research Institute, Tafo, Ghana. pp. 62.

Derivation: Imperial College Selections.
Location: ICTA, Trinidad and Tobago.

Notes: Lockwood & Gyamfi, 1979 [LOC79A] Selections from farms in Trinidad (1-100) and from Criollo progenies (101-107).

Cope, 1949a [COP49A]. One hundred selections were made as a result of a survey started in 1930 by Pound.

Bartley, 1993a [BAR93A]. Numbers 1 to 100 were selected from all over Trinidad, numbers 101 to 107 were Criollo trees selected from a farm but all have been lost and numbers greater than 111 are selections made in an experimental programme.

Bartley, 1996a [BAR96A]. The ICS material includes several clones which resulted from recent (at that time) introductions. These include Criollos from Nicaragua (ICS 60 and its relatives) or Venezuela. Other ICS clones represent "Amazonian" types originally introduced from the Orinoco. It is likely that several introductions were involved in creating the diversity that existed in Trinidad when Pound started the selection work.

Bartley, 1997b [BAR97B] From ICS 113 onwards these clones were used as parents in the AX / MX series. The same cross be known by an equivalent C [TTO] name.

Notes

Cote d'Ivoire - CIRAD/IDEFOR Datafile: CIV___DS CIV - CIRAD/IDEFOR Clone trial Germplasm: 67 clones were compared in five clonal trials. IFC 5 was used as a control in each of the trials.

Analysis carried out on the following number of harvests: D11/2 - 1979/80 to 1981/92 3 harvests D13/4 - 1977/78 to 1981/82 5 harvests G8 - 1978/79 to 1981/82 4 harvests A18/2 - 1987/88 to 1991/92 5 harvests Sensitivity to pod rot was calculated as the ratio of rotten pods to healthy pods. Sensitivity to mirids was calculated on a scale of 0 to 4 according to the amount of die back caused by mirid damage since the year of planting.

Trinidad - CRU, University of the West Indies Datafile: DIS_PHDS - Disease reaction to Phytophthora STOMA_DS - Leaf/Fruit Anatomical Characteristics Germplasm: Information on 12 clones grown in the ICG,T. Environment: See details given for TTO - ICG,T Descriptors. Descriptors: Characteristics of the stomata, surface wax, exocarp and mesocarp hardness, exocarp and endocarp thickness of the pod are described in relation to infection by Phytophthora. Experimental Conditions: Each clone was represented by 15 trees at the ICG,T. Fully grown unripe pods were used. The multiple point inoculation method was used to assess frequency of lesions. A drop of inoculum (4 micro litres) was applied using a micro pipette at 10 points along the ridges of the surface of detached pods, with a zoospore concentration of 30,000 per ml. The control treatments recieved sterile distilled water. The pods were arranged in a completely randomised design with 5 replications in plastic trays lined with moist paper towels and covered with another plastic tray. The trays were enclosed in plastic bags and incubated at 25 degrees C. After 72 hours frequency of lesions was assessed based on the mean of successful inoculation points observed. Four trials were conducted. For stab inoculation a standard injury was created on the pod surface using 20 pins penetrating to a depth of 3mm. Inoculation followed Sreenivasan (1985) placing a 4mm. diameter disc of filter paper immersed in a zoospore suspension 200,000 per ml on the wound and covering with a spot plaster. Controls were treated with sterile distilled water. Pods were arranged in completely randomised design with 5 replications per clone and incubated at 25 degrees C. in trays lined with moist tissue paper and covered with plastic film. After 5 days the area of the established lesion was determined by transcribing the outline of the lesion onto brown paper and the area of the cuttings determined by a leaf area meter. The experiment was conducted twice. Data collected was subjected to square root transformation and analysis of variance to determine significance. Character data: Immature pod, stomatal pore length: 10 pods were assessed at five points per pod for each clone. Mature pod, thickness of exocarp on ridge: each pod was measured at 5 points on the ridge. 10 pods were assessed per clone. Mature pod, thickness of exocarp on furrow: each pod was measured at 5 points on the furrow. 10 pods were assessed per clone. Mature pod, thickness of endocarp on ridge: each pod was measured at 5 points on the ridge. 10 pods were assessed per clone. Mature pod, thickness of endocarp on furrow: Each pod was measured at 5 points on the furrow. 10 pods were assessed per clone. Exocarp and mesocarp hardnes: tested at the equatior of the pods. 10 pods were assessed at 5 points per clone. Relative hardness was estimated in Newtons (N) per square mm. Pod wall moisture content: 5 pods were assessed for each clone. Wound: N=no, P=punch inoculation (4 mm hole), S3=stab inoculated to 3 mm depth, S9=stab inoculated to 9 mm depth. Morphological - Physiological Characteristics. Disease - Phytophthora palmivora, P. megakarya (Local Names: Black Pod, Podredumbre negra, Pourriture Brune, Podridao parda).

Notes

Trinidad - CRU, University of the West Indies Datafile: DIS_PHDS - Disease reaction to Phytophthora Experimental conditions: Each clone was represented in the ICG,T by 15 trees. Fully expanded green leaves of new flush (interflush 2) and mature unripe pods of similar size to ripe pods were used as test samples. Tissue paper mount inoculation of a 30 micro litre zoospore suspension was used to assess leaf resistance. The suspension was placed on the leaf surface with a micropipette and a 1 sq cm. piece of tissue paper was placed on the drop to allow even spread. Both adaxial and abaxial surfaces were inoculated on separate leaves with suspensions of 400,000 and 150,000 respectively. Seven replications of each clone were incubated at 25 degrees C. in plastic trays lined with moist paper towels and covered with polythene film for 72 hours. Control leaves were treated with sterile distilled water. The experiment was repeated twice. Established lesions were those with a minimum size of 0.4mm. Multiple point inculation as described in Iwaro, D. et al (1997a) was used to assess pod resistance. The 12 clones were replicated five times with controls and established lesions were those with a minimum diameter of 2mm. Four trials were conducted. Disease - Phytophthora palmivora, P. megakarya (Local Names: Black Pod, Podredumbre negra, Pourriture Brune, Podridao parda).

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.

Environment: Each clone is represented in the collection by up to 10 trees planted in a single row. Spacing is usually 2m within the row and 3m between the rows, although parts of the collection are planted in a 2.2 x 2.2m grid. Fertilizer, N-P-K-Mg/Ca in the ratio 18:10:6:5, is applied four times a year at 150g per tree. Shade is provided in most of the collection by an almost complete closed cover of trees of Erythrina poepiggiana and Inga spp. spaced at 12 x 12m. Character data: Seed dry weight: sample is dried for 1.5 h at 130°C and cooled in a desiccator. Seed length, seed width, seed thickness: average of 5 seeds from 20 fruits.
