摘　　要：对种植在闽西红壤区的17个油茶闽杂优无性系的生长及果实主要经济性状、产量、茶油品质等指标进行连续4a的观测。结果表明,在试验林粗放管理下,仍有闽杂优3、闽杂优11、闽杂优22、闽杂优32无性系的各项指标达到油茶优良无性系选育标准,其鲜出籽率41.90%~45.88%,干出籽率25.06%~25.44%,种仁含油率45.45%~46.73%,年均冠幅产果量1.21~1.38kg·m^-2,年均产油量为556.25~645.25kg·hm^-2,丰产稳产,抗性强,油脂品质优良,适宜在闽西红壤区推广种植。The growing situation,fruit main economic trait,yield,oil quality and other indexes of 17 Minzayou clones of Camellia oleifera planted in the red soil of Mountain-hill area of western Fujian were measured continuously four years.According to the yield monitoring and analysis from 2016 to 2019,in the case of extensive management of experimental forests,the various character indexes of four clones including Minzayou 3,Minzayou 11,Minzayou 22 and Minzayou 32 attained the standard of selecting and breeding of superior clones C.oleifera.Their fresh seed rate of fruit,dry seed rate of fruit and oil-bearing in kernel reach 41.90%~45.88%,25.06%~25.44%and 45.45%~46.73%,respectively.And their average fruit yield of unit crown area per year and oil yield were 1.27~1.45 kg·m^-2 and 556.25~645.25 kg·hm^-2,respectively.Having high and stable yield,high resistance and good oil quality,these four superior clones was fine and appropriate for popularizing in Mountain-hill areas of western Fujian.
