为了创制广西油茶( Camellia oleifera)新种质，开展了普通油茶优良家系杂交育种试验，重点对杂交组合与亲本的果实经济性状进行了对比分析。结果表明：油茶优良家系自花授粉呈明显不孕或孕性极低的现象；运用5个优良家系采用单交方式试验的15个杂交组合中，组合3、组合4在果实大小和单果鲜籽重方面表现出正向超亲优势，而其他组合的主要性状指标均趋向于某一亲本。普通油茶优良家系间杂交可以创制出超越亲本的杂种优势，通过组合亲本，获得具有特异性状的油茶新种质是可行的。

In order to create new germplasm of Camellia oleifera in Guangxi, hybridization experiment a-mong Camellia oleifera superior families was carried out, focusing on comparative analysis of fruit eco-nomic traits between hybridized combinations and their parents. The results showed that when Camellia oleifera superior families pollinated themselves, they had obvious infertility or very low pregnancy. Group 3 and group 4 had positive heterosis in fruit size and fruit fresh seed weight among 15 hybridized combina-tions by single cross with 5 superior families, while main character indexes of another combinations were tend to be one of the parents. Heterosis beyond parents could be created by hybridization among Camellia oleifera superior families, and new Camellia oleifera germplasm with specific traits was achievable through combination of parents.
