Bacterial soft rot caused by Erwinia carotovora subsp. carotovora is a major disease in Zantedeschia spp. Chemicals or modified cultivation methods only provide partial control of this disease. So highly resistant cultivars are needed to produce high quality calla flowers. Experiments were conducted to screen for Erwinia resistance in Zantedeschia spp. by a leaf disk test. To determine variation for aggressiveness, 20 Erwinia isolates collected from sites at Jeonju, Pyeongchang, and Suwon weredoi:10.17660/actahortic.2005.673.90 fatcat:qs7vejhvvne3ji3nzwvm44buda
