Abstract
本試驗係測定非洲稻種對臺灣稻熱病病原菌生理小種之致病反應，以供今後在非洲選拔抗病且高產之稻品種之參考。
1.達荷美、查德、沙烏地阿拉伯之稻種對本省稻熱病病原菌生理小種均呈抗病性反應。
2.race 3，13，17，20，21及24對象牙海岸稻種，race 3，13，19，21及25對塞內加爾稻種，race 13對加彭稻種，race 3及21對上伏塔稻種，race 3對賴比瑞亞稻種，race 19，20及24對獅子山稻種，race 13，19，21，22，24及25對馬拉加西稻種均呈感病反應。
3.臺灣主要稻熱病病原菌生理小種中對非洲稻種較為重要者為race 3，13，21及24等。
The purpose of this experiment was to test out the reaction of Africa varieties to the physiologic races of rice blast fungus exist in Taiwan to find out resistant varieties of rice.
The results are summarized as follows;
Among the thirty five varieties of Africa rice, four varieties of Dahomey, Chad, Saudi Arabia showed resistant reaction to all physiologic races of rice blast fungus tested in Taiwan while the rest varieties of Ivory Coast, Senegal, Gabon, Upper Volta, Sierra Leone and Malagasy showed correspoudingly susceptible reaction to race 3, 13, 17, 20, 21, 24; race 3, 13, 19, 21, 25; race 13; race 3, 21; race 3; race, 19, 20, 24; and race 13, 19, 21, 22, 24, 25
The four races 3, 13, 21, and 24 exist in Taiwan seemed more sensitive to the Africa varieties.
