Comparative Performances Of Slash Pine For Fusiform Rust Resistance In High Rust Hazard Locations

Rust infection of open-pollinated slash pine families, planted at four sites over two years, differed significantly among geographic origins and families. The year and site differences were even greater. Rank correlations of family infections among sites planted in the same year were good but those between the same sites in different years were poor. Correlation between sites was higher with moderately high infection levels at both sites than when there were large differences in average infection percent. Some families showed consistent rust resistance in all plantings while others were highly variable.
