Theobroma cacao Disease Resistance: Discovery and Functional Characterization of Genes Regulating Plant Immunity in Perennial Crops. NCBI

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

Mexico - INIFAP, Rosario Izapa Disease - Phytophthora palmivora. Datafile: DIS_PHDS - Disease reaction to Phytophthora EXPERIMENTAL CONDITIONS Immature fruit of 58 clones, four months old were innoculated with spores of Phytophthora palmivora isolated from a cocoa plantation. Innoculation was carried out with a drop on the surface on opposite sides of the pod, at a point near the widest circumference; each drop of the suspension was a concentration of approximately 24000 zoospores/ml. Innoculated fruit were covered in a plastic box which contained 10ml of distilled water in the bottom to maintain an atmosphere of high relative humidity. Evaluation of the results took place six days after innoculation. The size of the mark was taken as an average diameter from the point of infection.

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.

Soil type is fairly fertile young volcanic basalt. Average rainfall is c. 2100 mm/year well distributed, the driest month being February with about 150 mm. Descriptors: Cocoa butter analysis:- samples of a minimum of 2 kg were fermented in net bags placed in the fermentation heap and subsequently fast (i.e. continuously) dried. Determinations were carried out by MacRobertson Foods Pte Ltd. (a division of Cadbury-Schweppes Ltd.) in Singapore using a Nuclear Magnetic Resonance machine.

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.

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.

Flower descriptor data is presented for 620 clones, fruit descriptor data of 333 and seed characters of 118 clones are partly described. Leaf descriptor data is presented for 229 clones. 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
