| Abstract: | Chinese Fir is a fast growing wood species in China. A lot of excellent fast growing families were selected by selecting puls-trees, establishing seed orchards, progeny test etc. The regional test plantation was established with the selected excellent families. The analytical results of 5-year old plantation were showed as follows: (1) 41 excellent families were selected, and the average volume genetic gain was 23.9%, the selection rate was 39.4%. (2) The differences among sites, seed orchards and seed orchard x sites were all significant. The results showed that family selection would be efficient and the environment significantly affected the growth of Chinese Fir. (3) The benefit of establishing seed orchards was obvious. The average genetic gain of the 14 seed orchards tested was 18.6%. The gain from the central region was higher than that from the general region. The results was similar to that of provenance test. |
