Abstract:Poplar 741 is a clone of hybrid from 4 different species: Populus alba ×(P. davidiana+P. simonii)×P. tomentosa. The regional tests and character analysis for 741 show that it possesses the following advantages: fast growing, high quality, straight and round trunk. its average volume of 4-9 year-odd trees is 240% higher than that of P. tomentosa and 12—169% higher than that of P. tomentosa f. yixianensis. Its wood basic density, compressive strength parallel to the grain, bending strength and hardness are much better than those of P. tomentosa f. fixianensis. Its adaptability is also studied in this paper.It is conasidered that 741 can be used to plant forest for wood and get the genetic gain.
