This research was conducted in Boldaji research nursery from Chaharmahal and Bakhtiari province. At the first step, saplings of 39 clones from Alborz research nursery and 9 native clones were selected and planted on Boldaji research nursery in 1996. From these clones, 34 clones including 18 clones of Populus nigra, 11 clones of Populus x euramericana and 5 clones of Populus deltoides were established. After cutting the poplars from first and second year's nursery, three nurseries with 1/1, 1/2 and 2/3 age (right number: root age and left number: stem age) were created. Some factors such as germination percent, resistance to pest and disease, frost tolerance, height and diameter in 0.5 meter height were measured. The results showed that Populus nigra clones have most germination percent.Height and diameter growth of Populus euramericana 561.41 clone was more than other clones.
