| 摘 要： | 通过白榆苗期1年的试验结果可以看出：白榆种源、家系高生长之间存在着显著差异，白榆种源遗传力、遗传增益均大于家系，首先进行种源选择，再选择优良家系可获得更大的遗传增益。

| Abstract: | One year test for Ulmus Pumila at seedling stage showed that significant differences existed in growth among different provenances and families. The habitability and genetic gain of provenance were greater than that of the family. The first thing should be done is to select provenance and then select the excellent family would can get greater genetic gain. |
