Early inbreeding depression for (A) germination rate (%) and (B) survival until 4 weeks (%). For each of three parental backgrounds (PB1–PB3), control outcrossed progeny (white bars) were compared with selfed progeny (dark grey bars), and for PB3 also to biparentally inbred progeny (light grey bars). Sample sizes (n) are indicated within each bar. Significance of differences among seed classes was assessed by one-sided Fisher's exact tests (letters a–h identify individual comparisons). All comparisons showed significant differences, with the following exact P-values: Pa=2.0 × 10−2; Pb=2.0 × 10−6; Pc=5.7 × 10−4; Pd=1.2 × 10−3; Pe=1.3 × 10−5; Pf=4.8 × 10−9; Pg=2.7 × 10−3; Ph=3.3 × 10−4.
