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.
