Expedicao botanica a Amazonica brasileira. Cacau Atualidades (Brasil) 2: pp. 47-51.

Derivation: MAnaus city.
Collected by Vello.
Location: Careiro Island, Manaus, Brazil.

Lockwood, 1973a [LOC73A]. Fruit - large with thick shells, Beans - small.

Notes: Vello & Medeiros, 1965 [VEL65A] Collections made in 1965.

Bartley, 1997b [BAR97B] MA 1, MA 2 and MA 3 are not related to the rest of the series, in that they are selections made from seedling progenies planted in a CEPLAC experimental station near Manaus. This material was selected from locally cultivated varieties from a number of different trees planted in the Itacoatiara area, known to have been planted with cacao for over 200 years. Three selections were made from outstanding trees not necessarily representative of what was generally cultivated.

MA 11 onwards are Vello's collections.

Notes

Brazil - CEPEC, Itabuna, Bahia Datafile: DIS_PHDS - Disease reaction to Phytophthora ABSTRACT In order to select cacao parents for the Cacao Research Center (CEPEC) breeding program, 81 cultivars from CEPEC's Germplasm Collection in Itabuna, Bahia were tested for resistance to Phytophthora capsici, P. palmivora and P. citrophthora agents of black pod disease in Bahia. The cultivars tested belonged to the Brazilian series AM, BE, CA, CAS, CEPEC, EEG, MA, RB, SIAL and SIC and to the international series EET, GS, ICS, OC, PA, POUND, RIM, SCA, SGU, SPA, TSA, TSH and UF. Fully developed but unripe attached cocoa pods were point-inoculated without wounding by depositing a droplet of a 2 x 10E5/ml zoospore suspension in two places located on opposite sides of the pod. Ten replicated pods of each clone were used for each species at three distinct test times. The cultivar RIM 41 was included in all tests as a standard susceptible control. Percentage of successful infections and legion diameters were recorded 9 days later. Among 81 cultivars screened, seven were resistant to P. capsici, 21 to P. palmivora and only 2 (PA 30 and PA 150) to P. citrophthora. Only 9 cultivars showed the same reaction of tolerance (PA 30, PA 150, SIC 864 and SIAL 105) or susceptibility (AM 2, BE 3, BE 5, MA 11 and SIC 23) to infection by the three species. Based on a cluster analysis 21 cultivars (CAS 2, CEPEC 13, EET 59, EET 156, EET 228, EET 376, ICS 1, PA 16, PA 30, PA 81, PA 121, PA 150, PA 169, RB 40, RB 48, SCA 6, SIAL 105, SIAL 169, SIC 328, SIC 864 and SGU 3) were selected as promising parents to be used in CEPLAC's cacao breeding program. Parents selection was based on percentage of successful infections, legion diameters and bean production, following a proposed grading system. Among the selected cultivars PA 30 and PA 150 showed most promising resistance to P. capsici, P. palmivora and P. citrophthora. Disease - Phytophthora palmivora, P. megakarya (Local Names: Black Pod, Podredumbre negra, Pourriture Brune, Podridao parda).

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).
