摘要：The height of seedling, ground diameter and number of leaves were assessed for seedling cultivation techniques and l 51 Toona ciliata families. Analysis of variance showed that there were significant differences on studied traits among treatments. The medium treatment 1-2 （Yellow Subsoil： Vermiculite=1：1） and 2-6 （Light Medium） could improve the growth traits of seedling, suggesting that this two treatments could be popularized in seedling cultivation for Toona ciliate. The results showed that there were significant differences on studied traits among families, indicating clear differences among families. Coefficients of genotypic variation were 32.96% for height, 24.27% for ground diameter, 48.23% for number of leaves. Heritabilities were 0.96 for height, 0.81 for ground diameter, 0.91 for number of leaves. The strongly positive phenotypic correlations suggested that selection on one traits can be effective to predict other studied traits of Toona ciliata families
