Inbreeding depression in partially self-fertilizing
Decodon verticillatus: population-genetic and experimental analysis.
pisiformis tested in this study, but not tested by Zhang and Mosjidis (1995), is predominantly self-fertilizing ([PX.
varia was larger than that in the predominantly self-fertilizing species by more than 10%.
A polyploid that is self-fertilizing is more likely to spread in a diploid population because most matings will result in fertile polyploid offspring; outcrossing polyploids are more likely to produce inviable or sterile triploid offspring from 2x-4x matings.

Inbreeding depression studies on highly self-fertilizing species from a wide range of taxa are only recently becoming available, presumably because they are difficult to pollinate experimentally.
In our study, cumulative inbreeding depression was negatively correlated with selfing rate [ILLUSTRATION FOR FIGURE 2 OMITTED] and inbreeding depression in predominantly self-fertilizing species was 43% of that in outcrossing species (Table 1).
Predominantly self-fertilizing species in our survey ranged widely in inbreeding depression, from -0.
For the data based on three or four life-history stages, self-fertilizing populations had lower inbreeding depression at all stages except at growth/reproduction.
Populations in the lab and in nature consist of self-fertilizing hermaphrodites and rare males.
