| Abstract: | Based on 183 provenances selected from 13 provinces and regions, according to the BIB design of Chinese Fir provenance test, a variance analysis has been made on the height, diameter breast-height, and volume to show that: (1)a marked difference exists in the growth characteristics of the height, the D. B. H and the volume with a result that the quicker growth provenance Chinese Fir is 46% higher,55% bigger in D. B. H. and 2.16 times larger in volume than the slower one; (2) by way of a comprehensive praisal made on the various characteristics of the genetics distance, the provenances have been classified into 4 types, i.e. the fastest growth, the moderate, the slower and the slowest, of which the 12 fastest ones have the genetics gains of 5.22% in H, of 3.81% in D. B. H. and 12.65% in V as compaired with CK, there being a noted tendency that the 12 fastest provenances are centred mainly on Rongjian River valley, southeast of Guizhou Province and northwest of Guangxi Province, and the upper reaches of Minjian River valley, Fujian Province; (3) the provenances are of better heritability of 0.721 6~0.729 9,in H, D. B. H. and V, whose phenotype C. V. is larger than genotype C. V.; the volume genotype C. V. is larger than D. B. H. one, with the latter larger than the height C. V.; of 3 growth characteristics, the genetics variance components account for 11.3%~13.3% in the total variation,replication ones 17.7%~27.8%, and error ones 60.9%-69.0%. |
