Title: Chinese fir: genetic variation and combination selection for DBH growth and wood volume weight in the filial generation.
Abstract: This study was made in 10-year-old Chinese fir plantation of filial generation in Fujian Province .The result shows that there is a great difference in DBH and wood volume weight among filial generations .The genetic variation coefficient of DBH is 7.39 %, and wood volume weight is 4.45 %only .The broad heritability of DBH is
0.77 , and wood volume weight 0.86 .There is a negative correlation in heredity between DBH and wood volume weight , and correlation coefficient is -0.604 9 .Four superior cross combinations are selected by simple index method .Their genetic gain of DBH is 9.18 %, and wood volume weight approximates to the ck (Weimin F1 seed orchard).
