Abstract

Abstract: In this study, qPCR assays of the rice sheath blight (SB) pathogen inoculated to detached rice leaf tissues were performed to evaluate the disease level. Rice cultivars with the relative content of pathogen DNA in inoculated samples from the lowest to the highest are as below: YSBR1, Xudao 3, Taipei 309, Taijing 394, Lemont. The disease severity of leaf tissues indicated by the qPCR results was verified by precise control of the experimental conditions in SB inoculation, digital scanning of disease lesions, and statistical analysis of lesion areas. The average disease indexes of YSBR1, Lemont and Taijing 394 were significantly different from each other in field SB inoculation, further demonstrating that qPCR can be used to quantitatively evaluate the SB resistance level of rice cultivars. This study provides an effective method for quantification of the SB severity, evaluation of the resistance level of rice cultivars, and the forecast of the SB disease.

Key words: rice (Oryza sativa), sheath blight, detached-leaf inoculation, pathogen quantification
