Eucalyptus globulus is the most important plantation eucalypt in Australia and a model for tree genetic research. The project aims to study the quantitative genetic architecture of this species, focusing on traits of economic significance, and provide new insights into: the relative importance of non-additive genetic effects, including maternal and reciprocal effects; the importance of indirect genetic effects, particularly on the competitive interactions amongst trees; and the genetics of traits impacting the production of emerging plantation products such as veneer. This information is needed to improve genetic evaluation models and to better target germplasm to environments and products.

蓝桉是澳大利亚最重要的种植园林树种，也是林木遗传研究的典范树种。该项目旨在研究该物种的数量遗传结构，重点是经济意义的性状，并提供新的见解：非加性遗传效应的相对重要性，包括母体和相互效应;间接遗传效应的重要性，特别是对树木之间的竞争相互作用;以及影响新兴种植园产品（如单板）生产的性状遗传学。需要这些信息来改进遗传评估模型，并更好地将种质资源用于环境和产品。
