Abstract: The variety, ‘Chuangxin’, was selected from the progeny of Populus deltoides CL. ‘Nankang’×P. deltoides CL. ‘Imperil’ with artificial control pollination. It is male clone and an intraspecific hybrid of P.deltoides. Average DBH, height and volume of nine-years-old ‘Chuangxin’ were 19.90 cm, 18.0 m and 0.2064 m3, and the volume was 22.0% greater than control variety of ‘2025’. The elite variety has characteristics of straight trunk, middle crown, fast-growing, high resistance to Anoplophora glaberipennis and tolerance to soil barren.
