Sheath blight (ShB) response was evaluated in Arkansas, USA (AR) and Nanning, China (NC) using both field scoring and microchamber disease index (DI). Correlation values (r) are bold if significantly positive, italics if significantly negative, and black if not significant at α = 0.05. Significance at α = 0.01 and α = 0.001 are indicated with ** and ***, respectively
