One susceptible lesion developed on the seedlings of Toride 1 in 1979. The monospore culture derived from the lesion was inoculated to 9 differential varieties (shin 2, Aichi-asahi, Ishikari-shiroke, Kanto 51, Tsuyuake, Fukunishiki, Yashiromochi, Pi No. 4 and Toride 1) and Reiho, Mokoto, Nishihomare. Shin 2, Aichi-asahi, Yashiromochi, Pi No. 4, Toride 1 of these differential varieties and Reiho, Mokoto, Nishihomare showed susceptible reactions. The isolate was thus identified as a new race 703. When the susceptible reaction of Reiho was included, the race was designated as 703S. The number of susceptible lesions on Toride 1 and especially Pi No. 4 was fewer than that on other susceptible varieties under the conditions of 26 or 28 C after inoculation for about 20 hours. But the number of susceptible lesions on Pi No. 4 and especially Toride 1 increased when these varieties were placed under the conditions of 20 C for 5 days following inoculation. The isolate of the new race 703 (703S) and all tested isolates were pathogenic toward seedlings of barley, but only two isolates, race 703 (703S) and 102 (102S), were pathogenic toward seedlings of wheat.
