| 1. | They may kill newly established ramets . 新成长起来的无性系分株可能会被致死。 |
| 2. | Each clone has the same genetic information as the original . 每个无性系都具有与母体相同的遗传信息。 |
| 3. | Will it be sufficient to rely on the heterozygosity of one clone ? 是否依靠一个无性系的杂合性就足够了? |
| 4. | At the outset they must contain several ramets of every selected clone . 在开始时每个入选无性系必须包括几个无性繁殖后代。 |
| 5. | There are obvious differences between clones with regard to their self-fertility . 自交能孕性在不同的无性系中是明显不同的。 |
| 6. | Clonal propagation can also give some large gains in a relatively short time . 繁殖无性系也可以在较短期间内提供较大的增益。 |
| 7. | Potentially "high-yielding" clones are likely to be the material which first come to hand . 有“高产”可能的无性系大概首先是随手可得的材料。 |
| 8. | A compromise has to be made as to the choice of clones to be used as pollen parents . 对于用作授粉亲本的一些无性系的选择,不得不采用一种折衷办法。 |
| 9. | Its use is limited to the preservation of breeding material or the establishment of clonal seed orchards . 其用途仅限于保持育种材料或建立无性系种子园。 |
| 10. | Various clones families could be propagated commercially without having been clonally tested . 在这些家系中不同无性系被大量地繁殖,也没有进行无性系的测定。 |
