摘　　要：为研究油茶高产无性系在各地区的生长特性及稳定性,运用Eberhart&Russell联合回归分析、无性系×试验点的交互作用值估算等方法,对江西、贵州、浙江、湖北、安徽5个省6个试验点的8个油茶无性系生长性状区域化试验数据进行了分析.结果表明:长林4号具有较强的生长势和较高的稳定性,适应性最强;长林18号、长林26号和长林53号的稳定性高于平均水平,对环境的变化不敏感,高生长潜势易在不良环境中出现,在立地较好的环境下反而表现一般,适合在立地条件较差的地区推广;长林3号、长林27号、长林40号和长林166号属于生长势强健但稳定性较差的无性系,在立地条件较好的环境下表现良好,在立地条件差的环境下表现一般,适合在立地条件较好的地区推广.In order to study the growth characteristics and stability of oil-tea camellia,characteristics of eight clones from the data at 6 test sites located in Jiangxi,Guizhou,Zhejiang,Hubei and Anhui were analyzed with Eberhert-Russel regression analysis and clone-site interactions evaluation.The results showed that the clones Changlin 4 had the best adaptability due to its higher growth vigor and stability.Changlin 18,Changlin 26 and Changlin 53,whose growth vigor and stability were above the average level,were not sensitive to the change of environment.Their high production potential usually appeared in adverse environments and,therefore,they were suitable to be popularized in areas with bad site conditions.Clones 3,7,40 and 166 were suitable for good site conditions for they showed high growth vigor but low stability and were greatly influenced by environment in this study.
