Abstract: The plant self-incompatibility (SI) response is a common phenomenon in flowering plants, which prevents self degradation and maintains the genetic diversity of a reproductive segregation. The mechanism of self-incompatibility has diversity and independence, self-incompatibility mechanism among the various divisions is the origin of different, and genes of self-incompatibility are not homologous. This article summarized the classifications of plant self-incompatibility, and expounded different kinds of self-incompatibility mechanism according to the classification. Based on the results of summaries in this article, the research difficulties and the directions of self incompatibility were further analyzed.

Key words: self incompatibility, single factor SI, double factor SI, corn photo-thermo-sensitive self incompatible line
