摘  要:
为给油茶新品种选育及确定合理的杂交组合奠定基础,利用江西省林业科学院山茶属种质基因库丰富的油茶种质资源,采用有性杂交技术,于2005年选用12个油茶优良无性系、优良农家品种、油茶物种作为亲本,进行了12个不同组合的杂交育种试验,并于2006年10月采收杂交果实83个。通过试验得出不同杂交组合的平均坐果率,初步确定了不同亲本材料之间的杂交亲和力。其中,白皮中子×赣无1组合平均坐果率最高,为90%,表现亲和。

摘  要:
In order to lay a foundation for selection and breeding new varieties in Camellia oleiferaand determining reasonable cross combinations,a cross breeding experiment of 12different combinations was done in 2005by using sexual cross technology,selecting 12superior clones,superior cultivated varieties and species from Camellia Germplasm Gene Pool of Jiangxi Academy of Forestry as parents,and 83cross seeds was harvested in October,2006.The average fruit setting rate of different combinations was obtained through the experiment,and the cross affinity between different parent materials was determined preliminarily.The Baipizhongzi× Ganwu 1combination had the highest average fruit setting rate and showed affinity.
