摘　　要：采用聚合遗传值法，对９年生的印度、秦国、缅甸、尼日利亚等柚木种源９种性状进行评价，结果表明，除保存率外，各种性状在种源之间存在显著至极显著差异，并主要受遗传所控制。生长的早晚期呈紧密相关表明：对苗高进行汰劣性选择和在幼林生长初期作种源的生长评价，具有一定价值。为两个试验点评选的３０７１、３０７０、３０７４、３０７２、３０７８种源，在材积生长、质量和生活力方面具有很高的遗传效益，其中３０７１种源为最优。Nine characters of teak provenances from India,Thailand,Nigeria at 11 yearsold are evaluated according to a method of aggregated genetic value which has been used inthe evaluation of an international series of teak provenance trials. The results show that thereare sighificant or highly significant differences among provenances in 9 characters of growth,quality and viability except for survival rate. The great relevance between juvenile and agedtree of teak indicate that it is potential to make evaluation on the characters of provenance ofteak and selection of superior trees at the seedling stage.The superior provenances selectedare No. 3071,3074,3070 and 3072.Their volume growth,quality and viability can be herita-ble highly. Provenance 3071 is the best.
