Abstract
Crosses were performed using superior poplar clones of aigeiros section widely cultivated in Hubei Province to breed new poplar clones.The progenies showed abundant genetic variation and obvious heterosis.Both seedling height and root-collar diameter were traits with high heritability.Heritability in the broad sense of one-year old seedlings with one-year old roots in height and root-collar diameter were 76.74% and 5.22%,respectively.The general combining ability and specific combining ability of height were 21.56% and 78.44%,respectively.Those abilities of root-collar diameter were 61.39% and 38.61%.All of them were consistent with the one-year old seedlings with two-year old roots.Poplar resistances to the rust disease,canker and longicom beetles were polygenic.The resistance of progenies in rust disease was obviously related with their parents,but this kind relativity did not occur in resistance of canker and longicom beetles.According to growth of widely cultivated clones,obvious heterosis of higher-parent and genetic gain could be obtained after primary selection.Some progenies grew more rapid than the widely cultivated clones.
