The tree height, DBH and volume were analyzed for 19-year-old plantations of seventy-two chinese fir half-sib families planted in 1992 in Xishan forest farm of Rong＇ an county. The results showed that there were significant or very significant differences among all families in tree height, DBH and volume. The gains of tree height, DBH and volume were more 10 % than control in the fam- ilies which accounted for 19.4 %, 18.1% and 31.9 % of the tested families respectively. According to the differences of growth, twenty-one families such as Liu241, Liu449, Liu428, Linduol4, Liu244 were selected which were highly gains. The highest gain was 26.75 %, 23.50 % and 83.02 % in tree height, DBH and volume respectively.
