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。
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.
