Characterization of panicle blast severity distribution in progeny lines of Miyazakimochi/Bikei 22. (A–C) Frequency distribution of the severity of panicle blast among progeny lines derived from a cross between Miyazakimochi (M) and Bikei 22 (B). Closed circles and error bars, at the top of the graph indicate the average and range of panicle blast severity of parental cultivars, respectively. (D–F) Correlation between panicle blast and leaf blast severity. Regression lines, equations, and correlation coefficients (r) are shown for the progeny lines (L) and the parental cultivars (M and B).
