%X In order to obtain faster growth and high survival rate <em>Pinus koraensis</em> offspring families, with 51 <em>P.koraensis</em> families in Kaishantun Forest Farm in Longjing City, Jilin Province as materials, and studied their growth traits(seedling height and ground diameter), rate of survival and preserving rate. By analysis of variance, the traits were significantly different(<em>P</em>&lt;0.05) among different families except rate of survival at block-family interaction. The coefficients of phenotypic variation of all the traits ranged from 6.85%-29.89%. The heritabilities of different traits ranged from 0.51 to 0.80 except for the ground diameter in 4 a seedlings and rate of survival, and other traits showed their higher heritability. High variation and heritability values were beneficial to evaluation and selection of excellent families. Correlation analysis results showed that there were significantly positive correlations among all the traits. Using the method of multiple-traits evaluation, with a selection rate of 10%, family PK29, PK38, PK21, PK37 and PK48 were selected as elite families, and the genetic gains of seedling height and ground diameter were 10.08%-2.33%, respectively. The study can provide theoretical basis for evaluating <em>Pinus koraiensis</em>.
