Conspicuous varietal differences were found with the rice plant grown on the soil of the paddy field where H_2S is produced as regard to the degree of the root-rot caused by H_2S. The varieties having high adaptability to "Akiochi" (fall-down) paddy field showed higher resisting capacity for the root-rot disease as compaired with those having low adaptability. The writer has devised a convenient method to test the varietal resisting capacity for root-rot disease. The method is as follows:- The plant is taken from the paddy field and its root is immersed in a diluted solution of H_2S. After several days either the degree of blackening of the root due to FeS or the degree of root-rot is measured. The varieties resistant to root-rot have always lower degree of blackening and root-rot as compaired with non-resistant ones.
