| 摘 要： | 运用巢式固定效应模型，分析了油松亲本和苗期１３个表型性状在种源—林分—家系三个水平上的遗传差异。结果表明，三者中以家系间变异最大，种源次之，林分最小，分别占总变异的５８．７％、２８．１％和１３．２％。遗传力估值也以种源和家系较高。据此提出了油松遗传改良的最佳策略

| Abstract: | According to a nest design moddle,genetic variation of 13 phenotype characters of Chinese pine ( Pinus tabulaeformis Carr.) were analyzed among provenance,stand and family.The results showed that the variation of families is the most significant one of the 3 levels,the variation of provenances is the secand one, the variation of stands is the last one.The individual value of varianance on the 3 levels are 58.7% (families),28.1%(provenances),13.2% (stands).The value of genetic abilities of provenance and family is bigger too. The strategy of genetic improving of Chinese pine was put forward |
