Abstract:

In this paper the genetic correlation analysis on wood properties of new clones of Populus deltoides×P.Simonii was studied.The results showed that ring width was closely related to both earlywood width and latewood width genetically, but hardly related to latewood percentage.Ring density was closdly interrelated to the other wood traits genetically(r= 0.84—0.95), including earlywood density, latewood density, the minimum wood density and the maximum wood density, but weakly related tO both early—late wood density rate and the gradient of wood density.Moreover, the genetic relationship between ring width and ring density was negatie and very weak.
