In a previous paper evidence was presented which, it was argued, suggested that self-incompatibility in Papaver rhoeas was determined by a single, multi-allelic locus and that control of the pollen phenotype was gametophytic. In the present paper further evidence is given which proves that control of the pollen is gametophytic and which all but excludes the possibility that more than one locus is involved. The implications of these results in respect of the hypothesis that one-locus systems have evolved from multi-locus systems of self-incompatibility are discussed.
