摘  要:
以山茶属(Camellia)的普通金花茶、弄岗金花茶、大金花茶、防城金花茶、越南抱茎茶、宛田红花油茶、杜鹃红山茶、牡丹山茶花为试材,采用常规杂交育种方法,设计14个杂交组合,开展了金花茶杂交亲和性及杂种生长研究。结果表明:14个杂交组合中,有3个可结实(结实率50.00%~75.00%),且均获得了后代子苗(发芽率68.04%~100.00%);综合分析杂种在果实性状、种子萌发方面基本保留了母本的优良性状,F1代的幼苗生长量还略优于母本。目前杂种已正常培育,其后期表现有待进一步观测研究。通过组合亲本,获得具有特异性状的金花茶新种质是可行的。

摘  要:
Eight Camelliaspecies 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.
