Abstract

Investigation and analysis were made of semi-sib progenies for forests of ten-year-old Chinese fir in the seed orchard of Bamianshan State-owned Forest Farm in Hongya County.Results showed that there were significant differences in breast diameter,tree height and volume between 51 families.The real gain was significant,with a DBH gain of 6.3%,a tree height gain of 3.6%,and a volume gain of 16.7%.The maximum of DBH reached 23.7 cm in No.42 family.The highest value of tree height appeared in No.31 family,reaching 14.8 m.A comprehensive analysis showed that there were good volume gain and genetic stability in No.4,No.44,No.10,No.34,No.21,No.8,No.11,No.43,No.22,No.42,No.28,No.19,No.7 and No.47.
