摘要:杨树新品种‘中成1号’,雌株,通过人工控制授粉选育而成,美洲黑杨F2代种内杂种,其母本为丹红杨,父本为南杨。5年生平均胸径19.7 cm,平均树高15.8 m,单株材积0.174 6 m3,比对照I-69杨和中林46杨材积生长量分别提高33%和46%。窄冠,速生,树干通直,抗天牛,耐涝。
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-homed borers and waterlogging tolerance besides fast-growing.
