However, if galling intensity is used as a sole criterion for classifying resistance, a galling index that is greater than the resistance threshold (GI > 2) may not be practically significant for breeding when a source of high resistance (GI = 0) is needed in the development of new rootstocks ( Maquilan et al., 2018a ).
