Appendix 1
General combining ability (GCA) estimates of female parents, parental rankings (according to the GCA) and estimates of family-level inbreeding depression (FIDk) due to selfing (SELF) for DBH at different ages from planting. The results pertain to the 26 parents that are represented in both the SELF and Polymix (POL) cross types.

The GCA estimate of each parent is based on the data from the POL crosses, and it is
given in cm on an absolute scale (i.e. after adding the least-squares mean of the POL
crosses to the BLUP of the parent effect). FIDk is given in
cm on an absolute scale, as well as on a relative scale in parenthesis. Relative values
of FIDk were calculated as
FIDk/maximum, with “maximum” = LSM
when POL
outperformed SELF, or “maximum” = LSM
when SELF
outperformed POL (Ågren and Schemske, 1993; Dudash et al., 1997).
