摘　　要：【目的】为确定适宜重庆酉阳及周边区域种植的油茶品种,开展系统的多品种引种试验研究。【方法】以‘长林3号’、‘长林4号’、‘长林40号’、‘长林53号’、‘湘林210’、‘长林23号’、‘长林18号’、‘长林27号’等品种大树为研究对象,对比研究不同品种间树高、地径、冠幅、冠高等生长指标和果实产量、果实性状、种子性状等经济指标,计算果油率并预估理论产量。【结果】不同油茶品种在当地均能正常生长,但性状差异较大,‘长林53号’、‘长林3号’、‘湘林210’等品种在酉阳表现较好,理论产油量可达441.05~553.54 kg·hm^(-2)。【结论】‘长林53号’、‘长林3号’、‘湘林210’等品种有较大推广潜力,为产业发展和技术研究提供参考。【Objective】In order to determine the most suitable clonal lines of Camellia oleifera for cultivation in Youyang,Chongqing,and its surrounding areas,a systematic experiment was conducted to compare multiple clonal lines.【Method】Varieties including“Changlin 3”,“Changlin 4”,“Changlin 40”,“Changlin 53”,“Xianglin 210”,“Changlin 23”,“Changlin 18”,and“Changlin 27”were selected as research subjects.The study assessed various growth parameters such as tree height,diameter at breast height,crown width,crown height,as well as economic indicators including fruit yield,fruit characteristics,seed traits.Additionally,the oil yield rate was calculated,and theoretical yields were estimated.【Result】Results indicated significant trait variations among different clonal lines of Camellia oleifera while demonstrating normal growth in the local environment.Certain clonal lines,such as“Changlin 53”,“Changlin 3”,and“Xianglin 210”,exhibited favorable performance in Youyang,with theoretical oil yields ranging from 441.05 to 553.54 kg·hm^(-2),【Conclusion】“Changlin 53”,“Changlin 3”,and“Xianglin 210”suggesting significant potential for promotion.This study provides valuable insights for industrial development and technological research.
