RB 29 [BRA] Group Name Theobroma cacao

Vello, F. & Medeiros, A.G. (1965)
Expedicao botanica a Amazonica brasileira. Cacau Atualidades (Brasil) 2: pp. 47-51.

Derivation: Rio Branco.
Collected by Vello.
Location: Rio Branco, Acre, Brazil.

Bartley, 1995a [BAR95A]. Productivity - high. Flowers - generally have a "thickish" appearance with intensely and brilliantly coloured stamens such that the whole flower appears red. Fruits- small, Amelonado shaped, generally with thick husks. Seeds - small with dark cotyledons.

Notes: Vello & Medeiros, 1965 [VEL65A] 1965 Brazilian-International expedition.

Bartley, 1998a [BAR98A] Rio Branco is the name of several rivers and the name of a town in Acre.

Bartley 1997a, [BAR97A] The original Belem planting of RB clones comprised a mixture of types. This may account for the mixtures of genotypes in the CEPEC and CATIE collections with regard to RB 48 and RB 49. Any material distributed from CATIE should be identified as such to avoid confusion with clones from the primary source, which should be considered to be the correctly identified genotypes.

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).

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.

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
