YSBR1 shows high resistance to sheath blight (ShB) with a strong ability to suppress Rhizoctonia solani (R. solani) infection. (a) Evaluation of YSBR1 and Lemont in resistance to ShB disease in a field. Artificial inoculation was performed at booting stage for both varieties and ShB disease scores were rated at 30 days after heading. Photographs were taken at 30 days after heading. Values are means±s.d. Scale bar, 10 cm. (b) Lesion lengths and areas of adult plants were measured at different days post inoculation (DPI) in the growth chamber. Values are means ± SD. (c) Scanning electron microscopy (SEM) of R. solani hyphal behaviour on the surface of leaf sheaths of Lemont and YSBR1 at 24, 60 and 72 h after inoculation (HAI). 8‐week‐old plants grown in natural conditions were inoculated. The inoculated sheaths were collected at the indicated time points. Infection cushions are labelled with yellow arrows. All data are presented as mean ± SD, *, P < 0.05, **, P < 0.01 using Student’s t‐tests.
