MANCOVA examining effects of population, kinship coefficient between plants crossed, and their interaction on two estimates of fitness, sexual and clonal offspring performance

					F-ratio from univariate tests
Source of variation	Error term	d.f.	Wilks' F	P	Sexual performance	Clonal performance
Population	Pooled error	24, 554	2.75	<0.0001	3.12***	2.41**
Kinship coefficient	Population × kinship coefficient	2, 11	0.64	0.5477	1.39	0.98
Population × kinship coefficient	Pooled error	24, 554	2.02	0.0029	2.00*	2.09*

Significance of univariate tests is indicated (*P < 0.05, **P < 0.01, ***P < 0.001; N = 304; R² = 0.273 for sexual performance, and R² = 0.271 for clonal performance).
