| Abstract: | The tree height and base diameter of Pinus yunnanensis superior stand of Baimahe forest farm of Yongren county were measured to estimate and calculate the hereditability and genetic gain of the stand. The results showed that the hereditability and the genetic gain of tree height growth of Pinus yunnanensis natural superior stand were 87.9 % and 5.7 % respectively, that of base diameter growth were 52.6 % and 8.6 % respectively. |
