In order to discuss the cross compatibility and hybrid seed vigor of sympatric species among Guralensis, Gglabra and Geurycarpa distributed in Xinjiang, the cross fruiting rate, the pollen germination on stigma, the pollen tube growth in style after cross pollination and germination parameters of hybrid seeds were analyzed. Results showed that there was highly cross compatibility among these three Glycyrrhiza plants and their hybrids seeds were highly vigor. It suggested that the interspecific isolation mechanism of the three Glycyrrhiza plants was weak. Moreover, the natural hybridizations may occur and form natural hybrid zone.

Key words: Glycyrrhiza species, Interspecies cross, Compatibility, Hybrid vigor
