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.

Trinidad - Imperial College of Tropical Agriculture, University of the West Indies Datafile: DIS_CEDS - Disease reaction to Ceratocystis Descriptors: Resistance to Ceratocystis fimbriata based on field studies and surveys of disease incidence after natural infection Environment: River Estate, Regional Research Centre, Imperial College of Tropical Agriculture, Trinidad. 240 acres under a total of 87,000 cacao trees of various ages. The incidence of disease, i.e. the number of diseased trees in relation to the total number of trees as at 31 January 1959 was 0.7%. In the short time since the disease broke out at River Estate all the cacao has not been uniformly exposed to infection and therefore, final conclusions cannot be drawn on the relative susceptibility of different clones or seedlings. Nevertheless some observations are of interest. Germplasm: Initial survey remarks on 13 ICS genotypes, 2 IMC genotypes and 2 SCA genotypes. Progeny of controlled crosses and open pollinations of ICS clones.

Notes

Malaysia - Quion Hill, Sabah and Ulu Dunsun, Sandakan Datafile: DIS_VSDS - Disease reaction to VSD Descriptors: Resistance to infections from Vascular Streak Dieback Environment: Set 1 assessed at Quoin Hill at seedling stage in a nusery with the source of natural inoculum from surrounding infected mature fields. Sets 2 and 3 were evaluated at the mature tree stage. Germplasm: 79 hybrids evaluated in three sets. Set 1 consists of Sabah mixed hybrids raised specifically for this purpose at Quoin Hill, Sabah. Sets 2 and 3 are progeny trials established at Quoin Hill, Sabah and Ulu Dunsun, Sandakan respectively. Experimental conditions: VSD disease severity was recorded at intervals of one to two months throughout the epidemic period or at longer intervals throughout the rest of the year. Apparent infection rate (r or ADPC (area under disease progress curve)) are used as criteria to compare differences in the resistance of the hybrids. r is obtained by regressing In(1/1 - x) against time in months where x is the disease severity index. Differences between any two r values is tested using a t - test. ADPC is calculated and analysed using analysis of variance.

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.

Notes

Costa Rica - CATIE Datafile: CATIE__DS CRI - CATIE 1 IMAGE_DS PROGENY_ Germplasm: Descriptor information is presented for 294 clones, 8 related species and on one hybrid. In addition, limited information on a further 119 clones is given. This germplasm is mainly of Latin American origin, including the United Fruit clones, UF, and genotypes from Mexico and Brazil. 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. Fruit, wall thickness at ridge: fruits are transversally sectioned and the soft endocarp tissue removed. Fruit, ridge pair separation: mean ratio of the distance between ridges within a pair and the distances between the ridges of two different pairs. Leaf, flush colour: measured when leaves are 5cm long. Producitvity: values are given as: 1=very low - c. 40 pods harvested over 3 years; 3=low, 5=intermediate - c. 40 pods obtained from 3-4 harvests over 1 year; 7=high, 9=very high - c. 40 pods harvested at one time.
