| 摘 要： | 遗传相关分析表明,巨桉家系各性状间相关极显著,胸径与材积的遗传相关比树高与材积之间的遗传相关更密切。遗传相关系数大于表型相关系数,以遗传相关系数进行间接选择较科学。通径分析进一步揭示,胸径是构成巨桉单株材积的最主要因素。

| Abstract: | The genetic correlation of characters of E. grandis family was analyzed in this paper. The results showed that different families had highly significant correlations in characters, and the correlation between DBH and volume was more significant than that between height and volume. Genetic correlation coefficients were higher than phenotypic coefficients and it was more effective to select E. grandis indirectly by genetic correlation coefficients. The path analysis revealed that DBH was the most important element to volume of E. grandis individuals. |
