This research was performed to analyze growth performance and pattern of eighteen families of hinoki cypress (Chamaecyparis obtusa), which were imported in Jeju region. The growths of ``Yako-7``, ``Muei-1``, and ``Sangsong-9`` families were superior to other families whereas those of ``Sanguen-3``, ``Yago-6``, and ``Hyena-2`` families were poor. The height growth between age 9-year to 15-year was superior to those between other ages. No specific growth pattern was observed in the diameter at breast height (DBH) by ages. Family heritability of height, DBH, and volume were estimated at 0.68, 0.75, and 0.75, respectively. Pearson``s correlation analysis showed that there was little juvenile-mature correlation in the growth of C. obtusa.
