Fig. 1 Disease index of fusarium wilt on radish plants inoculated with Fusarium oxysporum f. sp. raphani. 0, healthy plant; 1, plant with browning of the vascular system; 2, wilted plant with poor leaf development; 3, plant with wilting and chlorosis; 4, plant with wilting and necrosis; 5, dead plant.
Fig. 2 Disease symptoms of fusarium wilt in the field and resistant/susceptible plants in seedling test. A and B, wilting and chlorosis of leaves and browning of root vascular tissues in diseased plants; C and D, resistant and susceptible plants after inoculation with Fusarium oxysporum f. sp. raphani Heonggye-2 isolate.
Fig. 3 Distribution of the incidence rates of fusarium wilt (A) and mean disease indexes (B) in radish germplasm after inoculation with Fusarium oxysporum f. sp. raphani Honggye-2 isolate by soil-drenching with root-wounding. Resistant check cultivar is ‘Myeonsanmoo’ and susceptible one is ‘Asia baekchun’.
