Abstract:
The heredity variability of the height, diameter and volume growth, interaction effect of biomass and circumstance of 6~7 years old Fokienia hodginsii plantation including 17 geographical provenances and 48 families in Hunan province were studied. The results indicated that there were obvious differences in the height, diameter and volume growth at mountain, middle mountain and hill. Heritability of the height, diameter and volume is 0. 5561~0. 903 4, 0.630 3~0.9140, 0.670 1~0.914 3 respectively. Between the provenances and environment of interaction, the rank of the height, diameter and volume growth was mountain>middle mountain area>hill. Based on the selection standard on the volume growth exceeded (15%) of average provenances, 7 superior provenances and 16 families were tentatively selected with the genetic gain of 18.99~94.96%, 16.78~215.75% respectively. Based on the selection standard on the volume growth exceeded of average provenances, 99 superior provenance plus trees and 140 families plus trees were tentatively selected with the genetic gain of 63.66%~257.61G, 138.33%~878. 340//oo respectively.
