| Abstract: | 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. |
