Abstract

Abstract: ‘Zhongyu 1’, a female clone and intraspecific hybrid of Populus deltoides hybid, was selected from the F₂ progeny of Populus deltoides CL. ‘Danhong’×P. deltoides CL. ‘Chuangxin’ by artificially controlling cross pollination. The average DBH, height and volume of five-years ‘Zhongyu 1’ were 18.2 cm, 14.8 m and 0.1428 m³, which were 16.7%, 22.5% and 26.6% more than 108(P. euramericana cv. ‘Guariento’), respectively. The new variety has the fine characteristic of moderate size crown, up straight trunk, fast-growing, high resistance to long-horned borers.

Key words: poplar, variety, selecting and breeding
