| 摘要: |
| 应用随机扩增多态性DNA(Random amplified polymorphic DNA, RAPD)技术，对核果类果树（桃、杏、李、樱桃等）间的亲缘关系进行了研究。结果表明，杏与李间有着较大的遗传差异，具有不同的发育过程，中国樱桃和桃是由李分化形成的，杏与甜樱桃间有一定亲缘关系。 |

| The Relationship of Drupe Fruit Trees Redetected by RAPD |
|
|
| Abstract: |
| Random amplified polymorphic DNAs were used to research on the relationship of drupe fruit trees (peach,apricot,plum and cherry etc.).The results of UPGMA cluster proved that there existed a larger inheritance distance between apricot and plum which implied that they had different developmental experience.Chinese cherry and peach were generated by plum,and apricot and sweet cherry might have a close relationship. |
| Key words: drupe fruit tree,RAPD,affinity relation |
