Abstract:

In this study, 60 hybrid clones of Section Airgeiros were used as plant material and I-108(Populus×euramericana‘Guarien’) was the control, combining with the disease resistance, wood and pulping properties, nutrition using efficiency, and the growth testing in seedling in Beijing and multi-regional trials in different ecological areas, such as Linghai of Liaoning Province, Zhucheng,Juancheng,Ninyang and Juxian of Shandong Province, two new pulpwood varieties P.×euramericana cl.‘Bofeng 1’and‘Bofeng 2’were selected. The mean individual volume of‘Bofeng 1’and‘Bofeng 2’were 0.348 7 m3 and 0.323 9 m3 at the age of 6 years in Linghai, Liaoning Province, the growth rate were respectively 23.52% & 14.73% higher than CK I-108(0.282 3 m3). Both the new selected varieties had the characteristics of fast growing, high disease resistance, good wood properties, high nitrogen using efficiency and wide-ranging adaptability. As the new poplar varieties for pulp wood,‘Bofeng 1’and ‘Bofeng 2’are especially suitable to plant in the region around the Bohai Bay in northeast China.
