Progeny testing of plus trees and selection of Fokienia hodginsii

    Corresponding author: HUANG De-long

Abstract: In order to chose plus trees of Fokienia hodginsii to utilization,mensuration and analysis were conducted on 80 families of Fokienia hodginsii from 5-year-old progeny in the National Forest Farm of Yongan,Fujian Province,in 2005. We used balanced lattice square method with 10 replications. Results showed significant differences(P<0.01) among families for tree height,diameter at breast height (DBH),and stem volume which were mainly controlled by genetic factors. According to progeny tests and based on stem volume while considering tree height,DBH,and straightness,thirteen superior families(J007,N001 etc.) and 35 superior individuals(Di001,Di002 etc.) were preliminarily selected. For 13 superior families,average tree height was 4.05 m with a 9.36% average genetic gain,average DBH was 5.57 cm and 16.46%,and average stem volume was 0.005 94 m3 and 33.77%. For the 35 superior individuals,average tree height was 4.65 m with 24.19% average genetic gain,average DBH was 7.5 cm and 42.17%,and average stem volume was 0.010 66 m3 and 146.93%. These superior families and individuals showed favorable growth traits and could be used for seed orchard or vegetative propagation. [Ch,6 tab. 10 ref.]
