| 摘 要： | 通过对陕西陇县八渡97个优树自由授粉子代进行遗传测定,结果表明:油松家系间树高、胸径和材积均达到极显著水平,家系内个体间方差分量也较大,个体变异明显;生长性状间的遗传相关系数较大,为材积间接选择提供理论依据,而环境相关系数反映了油松生长家系对环境反应比较敏感;采用独立淘汰法选择出优良家系17个,树高、胸径和材积遗传增益达到5.6%、11.5%和28.2%。 |

| Abstract: | Progeny test was carried out on 97 open-pollination families of Pinus tabulaeformis.The genetic analysis showed that there are significant differences among the height,DBH and volume;variance component among the individuals are of significant difference too.Growth traits have high relevance to genetic coefficiencies,providing a theoretic foundation for volume selection.Environmentally-relevant coefficiencies are the reflection of the sensitivity of Pinus tabulaeformis family to environment.10 super families are selected on the basis of independent eliminative method,with their genetic gains out of height,DBH and stock volume reaching 5.6%,11.5% and 28.2%,respectively. |
| Keywords: | Pinus tabulaeformis genetic variation open pollination progeny test |
