Baseline surveys at IRRI’s key research site for acid upland rice-based farming systems in Claveria, Mindanao, indicated that upland rice-based patterns were less widespread than maize-based patterns. This was attributed to a number of unique constraints associated with upland rice production, including late-maturing cultivars that prevented production of a succeeding crop. Cultivar evaluations of elite upland rice breeding materials were conducted to identify promising cultivars adapted to the acidic (pH
