| 摘 要： | 对31个柳杉优树自由授粉的子代苗期和造林 1～3年早期测定表明,子代间存在着明显的性状变异.经综合评定,选出早期生长优良的3个优良家系,可获得树高12.06%、胸径68.81%的相对遗传增益,同时,优树子代内也有明显的性状变异,具有进一步优中选优的潜力.

| Abstract: | The early test for thirty-one elite trees obtained from f ree pollination in their seedling stage and 1-3 years old plantation shows a significant character variation between their offsprings.By comprehensive evalu-tion, three fine pedigrees growing well during early stage were selected. Their relative genetic gain reaches 12.06% in tall and 68.81% in dreast high diameter. Meanwhile, the evident character variation also exists among the offsprings of elite trees. |
