In order to know whether or not the artificial inoculation onto leaf blade can be used as measures of the scab susceptibility, several wheat varieties, which were known for their susceptibility to scab, were subjected to the leaf blade inoculation. The result, however, did not show any reliability of this method. The foliage lesion was similar in the resistant varieties as in the susceptible ones, whenever the scabs were inoculated. In both the resistant and susceptible varieties, the development of the disease was stopped within several days, without further progress of symptoms. The mycelia were found only in the diseased tissues. The result of this experiment may be explained by suggesting that the mycelia invading into leaf tissues by the nutrients from agar are incapable of utilizing the wheat cell sap; for this reason, no difference in the degree of foliage lesion could be seen in spite of the marked difference in the scab susceptibility of wheat varieties. This hypothesis will be supported by the future works.
