WebMore recent esti- mates are that around 50% of angiosperms are self-incompatible (de Nettancourt, 1977), which would mean that the absence of self incompatibility in our 17 species is statistically very unlikely to be due to random sampling of plants in general (χ2 = 17.0, d.f. = 1, P < 0.001; goodness-of-fit test). WebAbstract Sexual reproduction in many flowering plants involves self-incompatibility (SI), which is one of the most important systems to prevent inbreeding. In many species, the self-/nonself-recognition of SI is controlled by a single polymorphic locus, the S-locus.
