摘　　要：The genus Corylus is an important member in the Betulaceae family of the order Fagales. Self-incompatibility is one of the choke points in breeding and hazelnut production. This reviewe describes, the progress on pollen-stigma compatibility in Corylus, including basic re- productive characteristics, S-alleles testing and their applications, in- ter-specific hybridization, self-compatibility in wild species, and recent molecular research on the genetic mechanism of compatibility. Com- pared with other species, progress on pollen-stigma compatibility （sporophytic self-incompatibility, SSI） in Corylus is slow, especially those in the Brassicaceae family. De novo approaches should be used to target the unique reproductive characteristics of hazelnuts. The continu- ous improvement of technological platforms based on molecular biology should broaden the pathways in investigating compatibility in Corylus. In addition, research should be conducted on overcoming self- and cross- incompatibility, and approaches based on biological, chemical, and physical principles should be introduced. Both theoretical and practical study of compatibility in Corylus should be devoted to change the self-incompatibility trait into a benefit in the species evolvement and nut quality establishment.The genus Corylus is an important member in the Betulaceae family of the order Fagales.
