Abstract
The classical model of gametophytic self-incompatibility is based on a single multi-allelic locus, the S-locus. However, exceptions may involve as many as 4 different loci. According to this interpretation, the S-locus (or loci) control the active inhibition of incompatible pollen types. Although widely accepted, this model leaves several observations unexplained, three of which will be considered in the present paper.
