|Summary of ANCOVA results for sporulation capacity|
|Source||DF||Type II SS||F||p|
|Host x Pustule density||4||0.618||3.06||0.0393|
|Pathogen x Host||16||0.944||1.17||0.3636|
The response variable is total spore production (mg spores per cm2 of leaf tissue) and it was log transformed before analysis. Log transformed pustule density (pustules per cm2of leaf tissue) was used as the covariate. The interaction effect of pathogen genotype x pustule density was not significant and was removed from the model.
