Key Results: Ovules penetrated by tubes from self-pollen uniformly failed to develop into seeds, as expected from ovarian self incompatibility (or strong early inbreeding depression). ... Despite reducing visitation by some pollinators, emasculation led to increased seed production and reduced rates of seed abortion.

Which will lead to inbreeding depression?

Inbreeding depression and heterosis could be caused either by the presence of (largely recessive) deleterious mutations that are present at low frequencies in populations (so that inbreeding increases the frequency of individuals expressing their effects; the 'dominance hypothesis') or by alleles with heterozygote ...

Which pollination promotes inbreeding depression mostly?

The strategy for breeding F1 hybrid squash is to develop parental lines through self-pollination. However, it increases plant mean homozygosis, which is not the natural genetic state of a cross-pollinated species, and can cause "inbreeding depression".
