Riviera & Salas, 1989a [RIV89A], Riviera, 1989a [RIV89B]. A collection of 120 elite plants noted for high pod production (100-300 pods) and resistance to Black pod. Selected from the farms "San Ignacio", "La Soledad", "Villa Edna", "San AgustÃn Ixtacapa" and "Buenos Aires" in San Antonio and "El Recreo" in Cuyotenango in the state of SuchitepÃ©quez. From these selections, 40 commercial clones were selected.

Costa Rica - CATIE Datafile: DIS_MODS - Disease reaction to Monilia Pod Rot Descriptors: Resistance based on severity of infection of Moniliophthora roreri using the aspersion method Environment: CATIE, Costa Rica Germplasm: Clones held at the CATIE germplasm collection Experimental conditions: External severity of infection: scale of six values, assessed 9 weeks after inoculation (0 = healthy pod, 5 = necrosis and sporulation). Internal severity of infection: scale of six values, assessed 9 weeks after inoculation (0 = 0% of internal tissues affected, 5 = more than 80%). This parameter was used to classify the cultivars. Incidence of infection: sick pods in relation to inoculated pods.
