Abstract: Self-incompatibility (SI) was widespread in plants. And it was one of the most important mechanisms which developed through long-term evolution of plants to prevent plants from selfing and maintain genetic diversity. The various mechanisms of plant self-incompatibility were controlled by different amounts of genes. Up to now, many experiments attested self-incompatibility in Poaceae which was controlled by two unlinked loci (S and Z) which both had series of alleles. This paper described the origin of S -Z self-incompatibility system in Poaceae, and summarized the progress of self-incompatibility genes about Secale cereale, Phalaris coerulescens, Hordeum bulbosum, Lolium perenne and so on. In addition, it also questioned this system. At last, drawing a high-resolution mapping of S and Z locus by conquering the self-incompatibility of O. longistaminata to construct segregating population was proposed.
