Abstract: The region tests of the second_generation seletions were arranged in the main distribution of Chinese fir in China in 1992. The results of studies on 39 families of the early stage in the site of Huangshan showed that the families of the second_generation improvement had a good production level, but the difference of growth among families was significant, so re_selection from the families of the second_generation and then generalization would bring good potential of increase of growth. The expected genetic gains of height, dbh and volume of 16 re_selectecl families would be 6.22％～11.43％，8.86％～25.36％ and 21.43％～53.76％ respectively. The correlation between the growth of family and the ability of anti_snow damage was at 0.01 level, so it was possible for the joint selection of growth and anti_snow. 
