Eucalyptus are the potential species for biomass production and carbon sequestration. Considering the demand for superior planting material of Eucalyptus a clonal evaluation trail was established with 18 clones at 2 x 2 m spacing. Data at the age of six year was recorded for growth, biomass and carbon storage potential. Significant variation was observed among all the clones for the studied parameters. Based on the findings clones such as EC-8, EC-4, EC-11, EC-10, EC-13 and EC-1 are shortlisted as clones with superior growth, biomass production and carbon sequestration potential. Fresh biomass was correlated with volume and carbon storage through regression equation. The association between Volume (m³) with Fresh Biomass (kg tree-1) and Carbon storage (kg tree-1) among 18 Eucalyptus clones was found to be strong (R² = 0.9645). Further to understand the genetic control of the studied characters genetic estimates i.e., GCV, PCV, H² and GG were worked out. Regression equations are also suggested for estimating standing fresh biomass and carbon storage of Eucalyptus clones
