Abstract The potential of breeding Zantedeschia cultivars for resistance to soft rot caused by Erwinia carotovora subsp. carotovora (syn. Pectobacterium carotovorum subsp. carotovorum) was determined. Hybrids of six cultivars (`Back Magic`, Galaxy`, Pink Persuasion`, Sensation`, `Treasure` and `Florex Gold`) were screened using a non-destructive resistance test (leaf disk test) and scored different levels of susceptibility. Some hybrid families were less susceptible than the very susceptible reference `Florex Gold`, while all hybrid families were more susceptible than the partial resistant reference Z. rehmannii. The half-sib family of `Pink Persuasion` was more resistant, but less vigorous than the half-sib family of `Florex Gold`. We concluded that resistance and vigour may be negatively correlated in the deployed cultivars and that resistance should be bred from other sources than the used cultivars
