Notes

A project to establish a new scientific approach for use with perennial crop plants to identify candidate loci for disease resistance using Theobroma cacao. Leaf samples were collected from the La Montaña field site at the CATIE field station in Turrialba, Costa Rica. The study focused on four genetic groups (Guiana, Iquitos, Marañon, and Nanay) and variation in resistance to Phytophthora.

Notes

Brazil - CEPEC, Bahia Datafile: DIS_WBDS - Disease reaction to Witches' Broom Experimental Conditions: Basidiospores were obtained from basidiocarps produced on brooms from Camacan, BA, Brazil, the source area of all inoculum used to screen germplasm. Brooms were hung inside "broom chambers" (vassoureiros) and kept in an 8 hr wet/16 hr dry environment as described by Suarez-Capello (1977) and Rocha and Wheeler (1985). Basidiospores were collected in a 16 percent glycerol solution and stored in liquid nitrogen as described by Frias et al (1995) prior to the inoculation tests. Basidiospore germination tests were performed spraying water-agar plates with the basidiospore suspension kept in liquid nitrogen the day before and immediately after the inoculation. The number of germinated basidiospores were recorded after 24 hr and the inoculum concentration adjusted to the number of viable basidiospores. Suspensions with spore germination of less than 75 percent were not used. At least 112 seedlings, divided in 4 replications of 28 seedlings each, of each of the 176 families obtained from open pollinated seeds planted in tubes with sterilized soil were inoculated when presenting a new flush with at least one leaf 1.5 cm long. 1 ml of a suspension of 75,000 basidiospores of C. pernisiosa/ml were sprayed by the automated inoculation system (Frias at al 1995). Plants were then kept in an incubation chamber for 24 hr at 24 degrees centigrade with 100 percent relative humidity. Individual plant responses were recorded 60 days after inoculation. In all inoculation tests performed SCA 6 and SCA 12 were included as standard resistant progenies and CATONGO as a standard susceptible progeny. Disease - Crinipellis perniciosa (Marasmius perniciosa) (local names: Witches' Broom Disease, Escoba de bruja, Balai de sorciere, Vassoura de bruxa).

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.

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.

Caqueta, Colombia and several of Pound's collections held at the San Carlos genebank. Environment: Accessions were either described at the time of collection or after planting in the field genebank at the San Carlos site of the INIAP Napo-Payamino Experimental Station in Napo Province. In the field genebank, a maximum of 10 seedlings for each collection were planted in a single row and budwood collections were planted as a row of up to 5 plants. Trees were spaced at 3m within the row and 4m between rows. Meteorological data are given in the table as mean daily maximum and mean daily minimum temperature and mean total rainfall per month. Soil analyses were carried out in the Department of Forestry and Natural Resources, Edinburgh University, UK. The table shows the means of duplicate analyses of five samples taken from the genebank site and the forest surrounding the genebank. Soil data: pH 4.2 Org. Mat.
