Abstract: In December 2021, investigations were carried out on height, DBH, crown width, basic density carbon content of 32-year Cupressus funebris of 45 filial families in Chun’an, Zhejiang province, taking local C. funebris tree (CK1) and first generation mixed line (CK2) as control. The coefficient of variation was analyzed, and the correlation between heritability parameters and different traits was estimated. The results showed that there were significant differences in growth, basic wood density, and stem carbon content among families. The variation of individual plant volume and stem carbon content was relatively large, while that of wood basic density and carbon density was smaller, with the coefficient of variation below 5%. The family heritability of measured traits ranged from 0.21 to 0.63, indicating that the traits were controlled by heredity except crown width. The correlation analysis showed that the selection of fast growing families could improve the carbon content of trunk at the same time, but had little effect on wood basic density and carbon density. Based on fast growth, high quality and high carbon sequestration, five plus families were selected, their single tree volume, basic wood density and trunk carbon content were 97.93%, 2.17% and 132.36% higher than that of CK2.
