Abstract: In order to select superior families ofPinus elliottii , seedling height and basal diameter of 1-yearoldPinus elliottii of 36 half-sib families in fine variety base clonal seed orchard of the State-owned Taolin Forestry Station were studied in this paper. The results showed that: there were significant differences in seeding height and basal diameter. The optimal families in seedling height were 0-1027, 0-456, II-101, 0-761, 11-16, 0-53, 7-245, 25,
