摘　　要：杂交育种是桉树遗传改良的重要手段。本研究以1个尾叶桉母本与巨桉、赤桉等4个树种为父本的10个杂交子代为研究材料，通过对它们1~5年生数据的分析，研究了杂种子代材积生长、抗风能力在树种、家系水平的遗传变异，分析了材积生长与抗风能力间的相关性，并根据研究结果对今后的桉树杂交育种提出了建议。Hybrid breeding is an important means of eucalypt genetic improvement. In this paper 10 families developed from a single Eucalyptus urophylla female artificially hybridized with 10 males from 4 different species were studied. Data on their growth from ages 1 to 5 years were analyzed to enable genetic variation for stem volume growth and typhoon resistance to be examined at both the species level and family level. Correlations between growth traits and typhoon resistance were also examined. Suggestions on future breeding of eucalypt hybrids were proposed based on the results from this study.
