| 摘 要： | 通过对7个无性系的苗高、地径的生长对比分析,可以看出各无性系间的高、径变幅较大,从而说明了可供选择的范围之大;同时各无性系苗高、地径、生根率的遗传力均在80%以上,说明了遗传的稳定性。 |
| 关 键 词： | 无性系 苗高 地径 早期选择 遗传力 |

| Abstract: | Comparing and analysing seedling heights and ground diameters of 7 chones showed that their heritability in height,diameter and rhizogenous rate was all above 80%.This indicated that the clones have better genetic stability. |
| Keywords: | clone seedling height ground diameter early selection heritability |
