摘要
通过１０．５年生９×９半双列杂交后代试验林的生长差异、配合力效应、遗传方差、遗传力和杂种优势的分析，进一步验证了一般配合力（ＧＣＡ）效应在杉木生长的遗传效应中起主要作用，特殊配合力（ＳＣＡ）效应起次要作用的结论。在杉木遗传改良进程的不同阶段，应选择具有ＧＣＡ和ＳＣＡ效应值不同的亲本分别用于育种园和生产性种子园的建设。
The growth difference,combining ability effect,genetic variation,heritability and heterosis were studied and analyzed by use of 10 5 years old Chinese fir progeny crossed 9×9 half diallel The results proved further that GCA played a leading role and SCA a secendary role in genetic effect of growth traits of Chinese fir During the different stages of Chinese fir genetic improvement,the various parents with different GCA and SCA should be selected as genetic materials of breeding orchard and productive seed orchard
