Abstract: 13-year poplar clonal stand in the 3 sites of Beijing,Hebei,Henan are observed for their growth character. 12 clones including 10 clones and 2 CK are tested for their wood properties. The test material comes from the test stands from Daxing,Beijing by sampling one tree from each of the 3 repeats for each clone. The analysis result shows significant variation of fiber length,fiber width and length/width ratio among the poplar clones,their repeatability is 0.777,0.537,0.676 respectively. The poplar clones,timber total density,spring wood density,fall wood density have significant variation,their repeatability is 0.536,0.517,0.429 respectively. Fiber length(YL)with age assumes exponential curve growth model: YL =7.195 5 e-0.836 9(t-1). Total density(YD)with age assumes fluctuated growth model: YD=0.505 3+0.000 67t. The heritablity is independent among the properties of fiber length,fiber width. 8 excellent clones are selected for Beijing,through the economical weights analysis and index selection of industrial timber properties such as volume increment,timber total density,fiber length and stem straightness. The comprehensive breeding gain of industrial timber can be higher than 20%. According to the conclusion of wood properties resulting from Beijing,excellent clones for two sites including Hebei and Henan are chosen.
