Abstract: To select suitable poplar varieties for cultivation in large scale in Jianghan plain, using nineteen introduced poplar clones such as‘Danhong’and the main planted poplar variety‘Zhongqian 3’of Jianghan plain as the materials, this article analyzed the growth, wood properties and resistance of the twenty poplar clones at six-year-old and twelve-year-old. The results showed that there were significantly differences in the DHB, height and volume among the six-year-old and twelve-year-old twenty poplar clones. Among all the poplar clones, five clones,‘Danhong’,‘Juba261’,‘DD102-4’,‘Nanlin 895’and‘Juba2025’, performed prominently, the volumes of which were higher than the that of‘Zhongqian 3’by 107.7%, 50.18%, 39.8%, 50.9%, and 42.1%, respectively, at twelve-year-old. The five poplar clones had differences or significant differences in basic density and fiber length. The‘Danhong’and‘Lushan’showed strong disease and insect resistance. According to the rhythm of volume rowth,‘Danhong’is suitable for cultivating little-middle DBH or big-diameter timber,‘Juba261’is suitable for cultivating big-diameter timber, and the other three clones are suitable for cultivating small and middle timber.
