摘　　要：选择天然营养有效成分和微量成分高且花量大、花多的防城金花茶(A)、凹脉金花茶(B)和越南红顶凹脉金花茶(D)3个品种的优树为杂交亲本,开展杂交亲和性和杂交生长研究。结果表明:杂交授粉64个,获得杂交果15个,结果率为23.4%。获种子37个,培育杂交苗15株,经1年培育,苗高均值为16.9 cm、地径为0.19 cm。目前杂交苗正常培育,其生长变异有待进一步观察,通过杂交,获得优质金花茶新品种是可行的。Three varieties of Camellia nitidissima(A),C.impressinervis(B)and C.impressinervis(D)were selected as hybrid parents to carry out cross-compatibility and hybrid growth studies.The results showed that 64 cross pollination and 15 cross fruits were obtained,and the fruiting rate was 23.4%.Thirty-seven seeds were obtained,and 15 hybrid seedlings were cultivated.After one year of cultivation,the average seedling height was 16.9 cm,and the ground diameter was 0.19 cm.At present,the hybrid seedlings are normally cultivated,and their growth variation needs to be further observed.It is feasible to obtain new varieties of high quality C.nitidissima through hybridization.
