The genetic effects of general and specific combining ability, male, female, and specific reciprocal cross were estimated for height, diameter of breast height (dbh), volume, crown-width, under branch height, crook degree and ratio of branch with shoot in Eucalyptus globulus Labill. Three quantitative characters, i.e. tree height, dbh, volume were focused, and their effects were discussed in detail. It was found that the GCA, SCA and specific reciprocal cross effects (SRE) were most important, and female effect (FEM) and male effect (MAL) were less important. Three parents with high GCA were good materials used for establishing seed orchard. Eight combinations significantly improved quantitative characters. One of them was improved on quantitative character and trunk quality at the same time. The breeding strategy and methods were also suggested for E. globulus.
对蓝桉的树高、胸径、材积、冠幅、分枝高、弯曲度和枝梢比等性状，估算了一般配合力、特殊配合力、父本、母本及特殊正反交的遗传效应。重点研究了树高、胸径和材积这三个数量性状，并详细讨论了它们的效应。结果表明，一般配合力、特殊配合力和特殊正反交效应最为重要，母本效应和父本效应相对不太重要。三个具有高一般配合力的亲本是建立种子园的优良材料。八个组合显著改良了数量性状。其中一个组合在数量性状和树干质量方面同时得到了改良。还提出了蓝桉的育种策略和方法。
