Abstract

Abstract: The‘Beiyang’, male clone and intraspecific hybrid of Populus deltoides hybrid, was selected from the progeny of Populus deltoides‘Nankang’×P. deltoides ‘D175’ by the way of artificial control cross pollination. Average DBH, height and volume of nine-year-old ‘Beiyang’ were 21.3 cm, 20.4 m and 0.250 m³, which were 49.9% greater than the control ‘2025'. The elite variety has the fine characteristics such as straight trunk, middle crown, fast-growing, strong resistance to Anoplophora glaberipennis and soil barren tolerance.

Key words: poplar, elite variety, selecting and breeding, resistance to insect
