摘　　要：富锦林木种子园6年生子代测定林生长结果表明:22个处理间和处理内遗传变异丰富,树高平均变异系数为28.91%,胸径平均变异系数为47.79%。处理间生长性状差异极显著,日5×长78-3、日5×兴12、日5×兴9、兴7×日77-2树高和胸径生长均排在前5名,入选优良家系,其树高平均值超出当地生产对照、白刀山种源、乌伊岭种源、和小北湖种源31.66%、73.04%、32.47%、和52.51%。树高和胸径的遗传力分别为81.07%和58.11%,遗传增益分别为37.66%和52.07%,增产效果明显。The growth of progeny in 6-years-old from Fujin forestry seed orchard indicates that there was larger genetic variation within treatments and treatment,the average variation coefficient of tree height was 28.91%,the average variation coefficient of diameter at breast height（DBH） was 47.79%.The growth traits were extremely significant within treatments,the tree height and DBH of four treatments grew among the top five,as superior families.The average tree height of four treatments exceeded CK、Baidaoshan provenance、Wuyiling provenance、Xiaobeihu provenance in 31.66%、73.04%、32.47% and 52.51%,heritability of tree height and DBH was 81.07% and 58.11%,genetic gain of tree height and DBH was 37.66% and 52.07%,it was obvious effection in increasing yield.
