In this experiment. the inoculation of scad into the ligule or the delicate parts inside the uppermost leaf sheath just below the ligule was carried out, using the wheat plants (Variety. Wheat Norin No. 12) which were water-cultured after being pulled out from the field. Only the hyphae, cultured on the potato agar medium, were applied, instead of the conventional method of spore inoculation. The treated plants were at or just after the heading stage. After the inoculation, they were grown in the glass-covered thermostat (23°C) in the room. The clear lesions were observed on the treated parts. From the results of this study, the conclusion was drawn that the hyphae of scab, even without spore, can be successfully applied in the attempt of inoculating the scab into the wheat plants.
