Effect of genotype, nutrient, and infection on fitness: effect tests
| Source | d.f. | SS | F-value |
|---|---|---|---|
| Genotype | 4 | 2963 | 35.1*** |
| Nutrient | 1 | 648 | 30.3*** |
| Infection | 1 | 104 | 4.9* |
| Flat (nutrient, infection) | 15 | 2979 | 9.4*** |
| Genotype × nutrient | 4 | 885 | 10.5*** |
ANOVA of effects on fitness with genotype, nutrient, and infection as fixed effects and “flat” as a random effect. Seed-yield data were cube root transformed to conform to assumptions of ANOVA. SS, sum of squares. *Significant F-values at P < 0.05; ***significance at P < 0.001.
