| 摘 要： | 经苗期对比试验，从全国１０省种源的１０４７株毛白杨优良基因资源中初选出３４个无性系进行中试，以比较速生的天然三倍体毛白杨雌株做对照。９年测定结果表明，鲁毛５０、５３１４、１４１４、５０１５和南×毛新五个无性系的材积增益高达３０％～５８．２％，且干形直，形态变异明显，易识别，适应性和抗逆性较强，有较高的推广利用价值。

| Abstract: | clones selected out of 1047 Populus tomentosa fine gene resource from 10 provinces through seedling contrast test was tested with fast growing female plants of Populus tomentosa as control,The results of test for 9 years show that 5 clones,Lumao 50,5314,1414,5105,and Nanmaoxin have high value of spreading and utilization because of their 30X2% increase of volume as compared with the control,strain stem form,remarkable morphological variation,easy to distinguish,and good adaptability and stress resistance. |
