摘　　要：对分布于广东省博罗县与增城镇龙镇2个试验点的23个引进南洋楹种源/家系进行调查观测。结果表明,生长性状和形质性状在种源/家系间表现出了不同程度的差异性,树高和形质性状在区组×种源/家系效应中存在显著或极显著差异,而胸径差异不显著。在0.05水平上与对照进行多重比较,筛选出若干单性状表现突出的种源/家系。运用主成分分析法对引进种源/家系进行多性状联合选择,分别为博罗和增城地区选择出优良材料:菲律宾家系(P1、P6、P8、P4)、马来西亚家系(M9、M3、M7)和菲律宾家系(P2)、菲律宾种源(P11)、马来西亚家系(M14、M15),可获得2.3%-14.0%材积遗传增益。The 23 intreducted Paraserianthes falcataria seedlots/families were tested in Boluo County and Zengcheng Zhonglong Town, Guangdong Province, the results showed that there were highly significant differences or significant differences in growth and stem-form qualities in seedlots/families, the differences of height and stem-form qualities in block × seedlots/families were highly significant or significant, whereas the DВН was not. Some superior seedlots/families highlighting in some single characters were selected by multiple comparison at level 0.05. The result of multicharacters＇ comprehensive selection produced by principal component showed that Philippines＇ family （P1, P6, P8, P4）, Malaysia＇s family （M9, M3, M7） and Philippines＇ family （P2）, Philip- pines＇ seedlot （P11 ）, Malaysia＇s family （M 14, M15） were considered as good materials for Boluo and Zengcheng, respectively, their volume genetic gains were between 2.3% and 14.0%.
