Producao e selecao de cacaueiros hibridos na Bahia. Proceedings of the 4th International Cocoa Conference, 1972, St. Augustine, Trinidad. Cocoa Research Unit, Trinidad. pp. 38-56.

Derivation: Selecao Instituto do Cacau.
Location: Bahia, Brazil.

Habit - prolific and vigorous. Fruit - thin husks. Seeds -small.

Notes: Vello et al., 1974a [VEL74A]. Clones with numbers less than 100 are from selections made from the area around the Experimental Station at Urucuca. Clones with numbers between 100 and 800 are the progeny from these clones and clones with numbers greater than 800 are selections from a CATONGO population at the same experimental station.

Bartley, 1995a [BAR95A]. Types include Para, Comum, Catongo and Maranhao. Possibly originally from Brazilian-Venezuelan border.

Bartley, 1998a [BAR98A] The clones in this series are constituted in the following way. Numbers 1-28 are selections made on the farm which was later developed into the Urucuca research station. Numbers 28-800 are open pollinated seedlings of the previous selections. They are random selections made without any discrimination. The rows of progeny were consecutively numbered in order of planting but unfortunately no records were kept of the original planting or of the parentage of each progeny. Numbers above 800 are seedling progenies of CATONGO. All basic characters of these plants should be the same so all of these must have white seeds if they are correctly identified.

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).
