The growth of Populus deltoides and Populus× euramericana clones from thegene-
pool in Changqing County,Shandong Province is studied. A significant variance is ob-served in
growth among clones. The broad- sense heritability for DBH and height are higherfrom the
fourth year on,and till the tenth year they remain above 0.7. There are differentcharactertstics of
growth and genetic variation between P. deltoides and P. × euramericana. The growth in DBH
and height at early stage of P. euramericanais superior to P. deltoides, till the tenth year, both
are basically the same. Average heritability of DBH is higher thanthat of height for P. ×
euramericana, but it is contrary for P. deltoides. The growth for P. deltoides shows significant
negative correlation to the original latitude.
