For each Rhynchosporium population (abbreviated by the country’s name) and trait, least squares mean (top line) and standard deviation (calculation based on isolate means; bottom line) are reported. The last three rows contain the mean, standard deviation (SD) and coefficient of variation (CV) across populations for each trait. For virulence, original, non-transformed data was used to calculate population means.
