Notes: Data are the mean ± standard error of two experiments (four replicates for each experiment). Statistical analyses of data were based on log10 (x + 1) transformed data. Means within a column followed by the same letters for each plant species are not significantly different according to Tukey's HSD test at P<0.05. aGI was based on a scale from 0 (no galls) to 10 (100% of roots galled) (Bridge and Page, 1980). bResistance is based on reproduction relative to the most susceptible genotype (55BA03-A1 and 55CA15-A2 for C. maxima and G9-A5 for C. moschata). Reproduction <10% that of the susceptible genotype is considered highly resistant (HR), £50% is considered moderately resistant (MR), and >50% is considered susceptible (S).
