Table 4.

Local versus foreign population contrasts of the plant performance of intrapopulation crosses at each site, based on the same dataset and statistical model of Table 3. Table entries of traits are F values of the linear contrasts, df = 1, N = 60 per site. The data of the F1 and F2 generations were combined in these analyses

Trait	Potsdam	Tübingen	Wageningen
Height1	0.03	6.72↓	0.01
Height2	7.13↑**	26.62↓***	0.27
Height3	6.81↑**	11.24↓***	0.45
Time to Flowering	9.89**	0.39	0.75
Fruit number	60.57↓***	5.37↑	0.86
Total Biomass	3.57↑	7.38↓**	1.29

“↑” indicates the direction of contrasts (local > foreign, suggesting local adaptation); “↓” indicates local < foreign, suggesting local maladaptation.

** and *** indicate P ≤ .005 and .001 respectively, significant after false discovery rates correction.
