Abstract

Abstract:

P.deltoides ‘Nanyang’, male clone and intraspecific hybrid of Populus deltoides hybid, was selected from the progeny of Populus deltoides CL.55/65'× P. deltoides CL. ‘2KEN8’ by the way of artificial control cross pollination. Average DBH, height and volum of six-years ‘Nan’were 20.70 cm, 15.0 m and 0.183 4 m³, which were 22.3% and 14.7% more than ‘Zhonglin 46’ and I-69. The elite variety has the fine characteristic of up straight trunk, narrow crown, fast-growing, high resistance to Anoplophora glaberipennis, moderate resistance to Apriona germari and waterlogging tolerance.

Key words: poplar, elite variety, selecting and breeding
