摘　　要：为了提高油茶果实产量,以湖北省油茶4个主栽品种(‘长林53’‘鄂油102’‘华金’‘华鑫’)为试材进行授粉配置实验,统计坐果率,并测定分析主要果实性状。研究结果表明:授粉组合对各品种的坐果率、单果重、横径、籽粒重、鲜果出籽率、干果出籽率、干籽出仁率、种仁含油量有显著影响;‘长林53’ב鄂油102’组合的坐果率较高;‘长林53’ב鄂油102’、‘华金’ב鄂油102’2个组合在单果重、横径、纵径和籽粒重方面较同母本其他组合更加突出。‘华鑫’是‘华金’的优良授粉品种,‘鄂油102’是‘华鑫’与‘长林53’的优良授粉品种;‘长林53’ב鄂油102’、‘华金’ב华鑫’、‘华金’ב鄂油102’是3个性状优良的授粉组合。该研究为油茶高产栽培提供了理论参考。In order to improve the fruit yield of Camellia oleifera Abel.,four main varieties of Camellia oleifera Abel.in Hubei Province(′Changlin 53′,′Eyou 102′,′Huajin′and′Huaxin′)were used as pollination materials to investigate the fruit setting rate and determine the main fruit characters.The results showed that the pollination varieties had significant effects on the fruit setting rate,single fruit weight,transverse diameter,grain weight,seed-setting rate of fresh fruit,seed-setting rate of dry fruit,seed-setting rate of dry seed and oil content of seed kernels;′Changlin 53′×′Eyou 102′had a higher fruit setting rate.The combinations of′Changlin 53′×′Eyou 102′and′Huajin′×′Eyou 102′were more prominent than other combinations of the same parent in terms of single fruit weight,transverse diameter,longitudinal diameter and grain weight.′Huaxin′was a good pollinator of′Huajin′,′Eyou 102′was a good pollinator of′Huaxin′and′Changlin 53′;′Changlin 53′×′Eyou 102′,′Huajin′×′Huaxin′and′Huajin′×′Eyou 102′were three pollination combinations with excellent characters.The research provided theoretical reference for high-yield cultivation of Camellia oleifera Abel..
