Abstract
The syringe method was newly adopted as an easy and reliable technique for selecting the rice plants resistant to sheath blight, Rhizoctonia solani. The method was as follows : 1) the fungus was cultured on PSA medium at 28°C for 2 days, 2) about 0, 25 ml aliquot of crushed agar culture was injected into the 3rd leaf sheath interstice at heading stage, and 3) in order to evaluate the resistant level of plants to sheath blight, the ratio of areas of disease lesion to that of total leaf sheath (disease scores) was used on 2 and 4 weeks after inoculation ; the most effective evaluation of the resistance level to the disease was made by reading the disease scores on the 2nd leaf sheath on 4 weeks after inoculation. Some of the F7 lines selected for the resistant to bacterial leaf blight were also found to be resistant to sheath blight.
