Abstract:

Populus deltoides‘Zhongcheng 1’, a female clone and intraspecific hybrid of P. deltoides, was selected from the F2 progeny of a cross derived from artificial pollination of P. deltoides cl. ‘Danhong’×P. deltoides cl.‘Nanyang’. Average DBH, height and volume of 5-year-old ‘Zhongcheng1’were 19.7 cm, 15.8 m and 0.174 6 m3, respectively, and the volume was 33% and 46% more than that of ‘I-69’and ‘Zhonglin 46’. The elite variety also has characteristics of narrow crown, up-straight trunk, high resistance to long-horned borers and waterlogging tolerance besides fast-growing.

Key words: Populus deltoides, new variety, selecting and breeding
