Trinidad - International Cocoa Genebank, CRU, University of the West Indies
Flower descriptor data is presented for 620 clones. The germplasm is mainly of Peruvian, Ecuadorian and Colombian origin. Fruit descriptor data is presented for 333 clones. The seed characters of 118 clones are partly described. The germplasm is mainly of Peruvian, Ecuadorian and Colombian origin. Environment: Each clone is represented in the collection by up to 16 trees planted 1.8 m apart in a block design. Shading is provided by Erythrina sp. (spaced 60m apart) and bananas (spaced 4m apart). Fertilizer, N-P-K (15:10:5), is provided twice a year at 250g per tree. Cyclic irrigation is performed from February to May (10 l of water per plant/week). Soil type group -33 A 1 Soil Series - Cunupia fine sandy clay with restricted internal drainage Lithology - silty clay alluvium Drainage - imperfect Slope category - 0°-2° Meterological data are given in this table as mean maximum, mean minimum and overall mean temperature and mean total rainfall per month over the period 1961-1990.

Where descriptor states present real measurements, e.g. pod length in cm, the data are given as the mean of all the measurements ± the standard deviation. For some descriptors, such as Leaf, flush colour, the phenotypic expression of the character is coded on a scale from 0 to 9. On this scale '0' represents the lowest or weakest expression of a characteristic and '9' represents the highest or strongest. Leaf and Flower Characteristics p.300-307 Character Data: Fruit, shell, percentage weight: for IMC 6, IMC 14, IMC 27, IMC 51, IMC 54, IMC 57, IMC 63, IMC 67, IMC 77, IMC 23, IMC 71 values for shell percentage weight were calculated after manual cleaning of beans. For all other accessions there beans were cleaned (mucilage removed) by using a high pressure water jet after the beans had been pre-treated with calcium oxide (possibility of some erosion of the testa or shell).

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. Pod outline drawing for each accession.
