| 摘 要： | 对杉木无性系生长性状、木材基本密度和管胞长度的遗传变异进行了研究。结果表明，无性系间树高、胸径、材积、木材基本密度和管胞长度存在显著至极显著差异。5个性状（树高、胸径、材积、木材基本密度和管胞长度）都受中等强度的遗传控制，无性糸重复力分别为0．771，0．651，0．566，0．529和0．495。树高、胸径和材积与木材基本密度、管胞长度间以及木材基本密度与管胞长度间呈遗传负相关。通过多性状综合指数选择选出2个纤维用材优良无性系。 |
| 关 键 词： | 杉木 无性系 木材基本密度 管胞长度 指数选择 |

| Abstract: | Genetic variations of growth traits,wood basic density and tracheid length of Chinese fir clones were investigated in this paper. The results indicated that the five traits like height,diameter at breast height,volume,wood basic density and tracheid length showed at least significant genetic variation among clones. They were under moderated genetic control with clone repeatabilities of 0. 771,0. 651,0. 566,0. 529 and 0. 495 respectively. Height, diameter at breast height and volume had a negative genetic correlation with wood basic density and tracheid length. The negative genetic correlation was also found between wood basic density a multiple nd tracheid length. Two superior clones were selected for fibre wood use based on traits combined index |
