| Abstract: | The study results show that there is an significant difference of Cunninghamia lanceolata second generation seed orchard progeny growth between families.The genetic differentiations between individuals inside families are acute.The increasing production effects of the planting of fine families selected from populations and fine individuals inside families are significant.The relatively high phenotype and genetic correlation of Cunninghamia lanceolata exist between growth characters of height,dbh and volume,etc. |
