Above ground biomass production of one-year-old hybrid poplars was investigated to select the best clones which are suitable for short rotation forestry. The results were as follows: 1. Average dry weight of Populus alba X P. glandulosa Fl clones was 2.86 for stem,0.41 for branches 0.70 for leaves and 3.97 t/ha for total. and the ratios of green weight to dry weight were 0.47 for stem,0.36 for branches,0.31 for leaves and 0.42 for total. Dry weight of Populus nigra X P. maximowiczii Fl clones was 1.48 for stem, 0.54 for branches.0.71 for loaves and 2.73t/ha for total, and the ratios of green weight to dry weight were 0.42 for stem. 0.37 for branches, 0.28 for leaves and 0.36 for total. 2. Biomass production (green and dry weight)of Populus alba X P. glandulosa F1 clones can be predicted by diameter measurement only, but biomass production of Populus nigra X P. maximowiczii F1 clones can not be predicted by any of investigated characteristics. 3. Dry weight distribution of pepulus alba X P. glandulosa Fl clones were 73
