Abstract: In this paper, biomass production and calorific values of components for oneyearold hybrid poplar clones were studied after one growth season. The results showed that the biomass production in 13 poplar clones were higher than population mean, and clones 208 had the highest biomass production in aboveground, underground and total, reached 485.77g, 146.18g and 631.95 g. Gross calorific values of components were also different, it was ordered as stem, bark, root. There were significant difference in seedling individual gross calorific values among all poplar clones, and the variation ranges were 18.659—19.141 kJ/g. The means of individual calorific values, biomass production and individual gross calorific values for poplar clones that were selected as elite clones were 26.12%, 25.99% and 0.12% higher than the population mean. The differences of individual calorific values for poplar clones were mainly determined by their biomass production.
