摘　　要：为了明确长林系列油茶品种的最佳配置组合,以5~8年生10个长林系列良种为研究对象,设计49个配置组合并进行人工控制授粉,对当代杂交果实的座果率、种实特征、种仁含油率以及油脂油酸含量进行了分析。结果表明:不同授粉组合对座果率、果实重量、鲜出籽率、籽粒数、单籽粒重和种仁含油率影响显著,对种子脂肪酸油酸含量无显著影响;油茶授粉座果率与果实重量、籽粒数存在明显的正相关关系,果实籽粒数和单籽粒重则呈现出明显的负相关关系;通过对品种间控制授粉的座果率、种实特征以及种仁含油率的综合评价,优化筛选出长林系列油茶良种的最佳品种配置组合6个,即长林21号和长林4号、长林21号和长林18号、长林53号和长林40号、长林53号和长林23号、长林53号和长林166号、长林3号和长林27号。In order to clarify the best collocation of ＇Changlin＇ oil-tea camellia varieties, five to eight years old oil-tea camellia trees from ten ＇Changlin＇ varieties were selected to carry out cross pollination test involved forty-nine combinations and the effect of different combinations on fruit set, seed and fruit characteristics, oil and oleic acid content was analyzed. The result showed that the fruit set, fruit weight, seed ratio, seed number per fruit, seed size and oil content in kernel were significantly influenced by different combinations, while no significant effect on oleic acid content was found. The fruit weight and seed number were positive correlation to the fruit set ratio apparently and a negative correlativity was found between seed number and single seed weight. The following six collocations were screened by comprehensive evaluation of fruit set, seed and fruit characteristics and oil contcat. They were ＇ Changlin 21＇ and ＇Changlin4＇ , ＇Changlin21＇ and ＇Changlinl8＇ , ＇Changlin53＇ and ＇Changlin40＇ , ＇Changlin53＇ and ＇Changlin 23＇, ＇Changlin53＇ and ＇Changlin166＇ , ＇Changlin3＇ and ＇Changlin27＇ .
