Sporophytic Self-incompatibility is reported in

Sporophytic Self-incompatibility is reported in Beetroot, Radish and Brussels Sprout.
Sporophytic self-incompatibility (SSI) is a self-pollen recognition system that enforces outcrossing in plants. It is a mechanism that prevents pollen from one flower from fertilizing other flowers of the same plant.
Recognition in SSI systems is typically controlled by a complex locus (S-locus) with separate genes that determine pollen and stigma specificity.
