Cuttings of ‘Reikoudai 1 gou’ line, Ficus erecta, cultivated fig varieties and existing resistant varieties were grown in soil, then a suspension with Ceratocystis ficicola, causative agent of Ceratocystis canker, was poured onto soil, to test whether ‘Reikoudai 1 gou’ was as resistant as F. erecta. After 180 days, 64–100% of cultivated figs and existing resistant varieties were dead; none of ‘Reikoudai 1 gou’ including wound-inoculated, or F. erecta were dead. Thus, resistance to C. ficicola of ‘Reikoudai 1 gou’ is equivalent to that of F. erecta regardless of inoculation method.
