| Abstract: | This papar deals with the diseases resistance of young trees of Populus cathayana Rehd of 294 individual trees from 22 different provenances by the method of statistics analysis .The results show that there are significant variations in all provenances and clones and few clones of the same provenances at 0.01 level, some provenances have a high index of infection to two diseases, others have a low index of infection to two diseases ,some provenances have a high index of infection to one, at the same time, they have a low index of infection to another, however,others are contrary. |

| Keywords: | Populus cathayana provenance clone index of infection statistics analysis |
