Abstract:: Eight Camellia species or varieties，including C.chrysantha，C.longgangensis,C.grandis，C.nitidissima and C.amplexicaulis，C.polyodonta，C.changii， C.japonica var.pleniflora，were used as experimental materials in this research,a total of 14 cross combinations were designs based on the conventional methods of crossbreeding，the interspecific reciprocal crosses and seed growth were carried out in order to study the compatibility.The results showed that in the 14 hybrid combinations，3 ones get hybrid offspring（seed setting rate 50.00%-75.00%）and obtain progeny seedlings（germination rate 68.04%-100.00%）.The hybrid seeds of intrasectional crossing all exhibited good characters of fruit,seed germination,the growth of F1 seedings was still a little better than that of female parent.The hybrid seeds had been cultured,and their late features needed further study.The new Camellia chrysantha germplasm with specific traits was achievable through combination of parents.
