Eucalyptus, Trial, PlantationAbstract
In recent years, dozens of fast-growing Eucalyptus clones were approved by Ministry of Agricuture and Rural Development as new advanced-technological varieties. However, only some of those clones were planted in a large scale, such as U6 and PN14. In order to put newly approved varieties into large-scale planting, trials of these varieties in major ecological regions of Vietnam should be
conducted. Trials of new advanced-technological Eucalyptus clones was built in 2010 in Truong Son, Luong Son, Hoa Binh and Luong Son, Thuong Xuan, Thanh
Hoa. After three years, clones PN10 and PN108 achieved a Mean Annual Increment (MAI) of more than 20 m3/ha/yr in trial in Thanh Hoa. Meanwhile, six clones (PN10, PN46, PN47, PN46, PN108 and PN14) in trial in Hoa Binh had a
MAI of more than 20 m3/ha/yr, especially clone PN108 had highest MAI (31.2m3/ha/yr). Leaf diseases occurrence in all trials but with low damage incidence and it has no impact on tree growth.
